Osteoporosis & CBD Oil: Best Products & Research on Building Bone Density
Osteoporosis is a medical condition in which bone loss exceeds the creation of new bone. Literally translated as, “porous bones,” the bones of people with osteoporosis become increasingly brittle and fragile as density decreases. All of this puts osteoporosis suffers at an increased risk of bone fractures, but CBD oil may be able to help.
Bone is not a static system, but is continually undergoing change. Under the influence of hormones and stressors, new bone is continually laid down while old bone is lost, or resorbed.
In a healthy individual, the rate of bone turnover is equal, meaning that there is not a net gain or loss of bone tissue. In osteoporosis, there is a net loss of bone tissue, leaving bones brittle and susceptible to fracturing.
There is plenty of research that is ongoing but the information that we have so far points to a number of ways in which using CBD oil for osteoporosis could be beneficial.
Benefits of Using CBD Oil for Osteoporosis
Bisphosphonates is the class of medication most commonly prescribed for people with osteoporosis. Bisphosphonates do an excellent job of slowing or even preventing bone loss, though unfortunately, these results come with some less than pleasant side effects. Many who are prescribed bisphosphonates complain of nausea, abnormal heartbeat, dizziness, and pain. Although bisphosphonates are generally thought of as the gold standard in the treatment of osteoporosis, they are not always very effective and sometimes bone loss does still occur after a few years of taking them.
If you’re taking bisphosphonates and are considering adding CBD oil to your wellness regimen, first speak to your doctor, and keep this chart handy.

For those looking for a relatively worry-free alternative to bisphosphonates, and some of the other prescribed medications, cannabidiol (CBD) is an excellent option. CBD has very few side effects and is non-habit-forming. Additionally, research exists that supports using CBD oil as a way to slow, or even stop, the bone loss associated with osteoporosis.
Effectiveness of Using CBD Oil for Osteoporosis
To get an idea for how CBD may benefit those dealing with osteoporosis, it is helpful to understand what plays a part in bone density. Two different types of cells affect bone density: osteoclasts, which degrade bone, and osteoblasts, which help produce bone. It is the balance between these two cell types that maintains homeostasis in bone density.
Research has identified a cell receptor on osteoclasts that, when stimulated, speeds up bone degeneration. This receptor, called GPR55, was found to increase the rate of bone loss when artificially stimulated in studies.
Researchers then went on to attempt to find a chemical or compound which could block the GRP55 receptor, and one such compound that proved effective was CBD. Researchers found that CBD effectively blocked the GPR55 receptor, resulting in a significant reduction in bone degradation.
Further research confirms CBD’s role in affecting the balance between osteoclasts and osteoblasts in the bones. Supplementing with CBD appears to tip the balance towards osteoblast, or bone-building, activity, resulting in increased bone density!
In another study, CBD was found to increase the rate of bone healing in rats with fractured femurs. CBD did so by encoding enzymes that increased collagen cross-linking, which is associated with overall bone strength. The study concludes with, “Taken together, these data show that CBD leads to improvement in fracture healing and demonstrate the critical mechanical role of collagen crosslinking enzymes.”
As the research into CBD oil for osteoporosis continues, we will reach a greater understanding of all the ways CBD oil may be able to help. With the evidence available now, CBD oil appears to be a safe and natural way to prevent or reverse osteoporosis without the side effects of traditional treatments.
How to Take CBD Oil for Osteoporosis
The first step to using CBD oil for osteoporosis is speaking with your doctor. While CBD oil is generally considered safe, it can interact with certain prescription medications, yielding unwanted effects.
Once your doctor has cleared you for safe use, you’ll need to choose how you’d like to take your CBD. If you’re interested in trying CBD oil for osteoporosis, there are plenty of great options available. CBD is available in a variety of different preparations such as:
For osteoporosis, any of the above options should be effective. CBD topicals, like lotions or salves, will provide targeted, external relief for hours at a time. However, because they do not penetrate past the skin, you may want to supplement with a CBD inhalant, edible, or drops to up your bone density by targeting osteoclasts and osteoblasts in your bones. It will take some experimenting to find which CBD delivery method(s) are most comfortable and effective for your needs.
Note from the Medical Editor: As mentioned before, unless there are fractures present, osteoporosis doesn’t really cause pain on its own. I think the best method would be edibles or drops to ensure consistent levels of CBD acting on osteoblasts/clasts.
While you’re trying out different CBD products, it is important to understand that different delivery formats will have different onsets and each will have a different duration.
For example, CBD vape oils and CBD flower can go to work in a matter of minutes but their effects are often gone within an hour. Whereas a CBD edible or CBD oil capsule can be slow to take effect, typically about an hour to start feeling effects, but can last for up to 6 hours.
CBD oil tinctures and drops are a good middle-of-the-road option, typically taking about 30 minutes to show effects and lasting for 2 to 4 hours. CBD oil drops and tinctures offer the best dosage control, making it easier to increase or decrease your dose as needed.
You may find that it takes more than one product to achieve desired effect. It may be best to supplement daily with a CBD oil capsule or tincture and apply CBD cream to areas with constant osteoporosis pain. You can use a CBD vape to address sudden aches when they pop up.
Given CBD oil’s safety profile, you can experiment without too much fear that something will go wrong.
CBD Oil Dosage for Osteoporosis
When it comes to selecting a proper CBD oil dosage, unless your doctor has advised otherwise, it is recommended that you start slowly with the lowest recommended dose listed on your CBD oil product.
If you’re having trouble finding a good starting dose, at CBD Oil Review, we have analyzed hundreds of products and come up with the following:
The CBD Oil Review Serving Standard is 25 mg of CBD taken twice daily.
This dose should be effective for most people, though individual results may vary. If you’re not seeing the effects you desire, increase your dosage by 25 mg every 3-4 weeks until you’re seeing results.
For more information on CBD dosing, consider reading through our dosing guide here, or speak with a naturopathic doctor for the most personalized action plan for using CBD oil to manage osteoporosis.

How Does CBD Help With Osteoporosis?
CBD (cannabidiol) is the primary non-psychoactive compound in cannabis. It’s been shown to support bone metabolism indirectly through its effects on the endocannabinoid system (ECS).
The ECS is a complex network of receptors that work to regulate various aspects of our health — including the formation and degeneration of bone . Through this system, CBD is thought to help reduce bone loss and promote the regeneration of lost bone tissue.
CBD should always be used in combination with other therapies for maximum benefit. CBD is not a cure for osteoporosis, but can offer a powerful supportive role when used alongside other medications, supplements, and exercises.
The benefits of CBD oil for osteoporosis may include:
- May improve the density of bones
- Alleviates pain & inflammation
- Supports hormone balance
- Relieves pain from bone fractures
1. CBD May Improve Bone Density
Research has discovered that CBD appears to enhance the growth and strengthening of bones through accelerated osteoblast formation.
Researchers believe that osteoclasts — the cells that breakdown bone — have a cell receptor that, when activated, speeds up bone loss and degeneration. This receptor is known as GPR55. CBD has been shown to specifically block the activation of this receptor, reducing osteoclast activity .
Further, in a recent study in Israel, mice were given CBD or a combination of THC and CBD. The study found that the administration of CBD alone has significant effects on fracture healing with increased bone strength and toughness by stimulating Lysyl Hydroxylase — an enzyme involved in bone healing .
This research has given us a deeper insight into how CBD influences the body and opens up some exciting potential for further research.
2. CBD Alleviates Pain & Inflammation
CBD may have a therapeutic role in inflammation and healing. It has long been used by people with chronic pain and offers a non-habit-forming alternative to pain medications.
Many patients have reported replacing their prescription pain medications with CBD, with evidence that its use can help in the treatment of headaches, mental health disorders, insomnia, arthritis, and other chronic pain syndromes .
What’s The Dose of CBD Oil For Osteoporosis?
The key is to start low and go slow.
As yet, there are no standardized dosing guidelines for CBD use. CBD oil can come in many different strengths. As products vary greatly, it’s important to read the label of the specific product you are using.
When it comes to managing osteoporosis, the benefits will take several months before any change is noticed. We recommend starting with a moderate dosage (based on your weight using our CBD oil calculator below).
If you experience side-effects (more on this later), reduce the dose until they disappear.

Is CBD Oil Safe?
CBD is safe, even at high doses — but there are a few exceptions to be aware of.
According to the WHO, CBD oil, in its pure state, does not cause harm or have the potential for abuse — even at high doses .
If you’re using any prescription medications, or have underlying health issues, you should always speak with your doctor before taking CBD. Certain medications may interact with CBD and lead to side-effects.
What is Osteoporosis?
Osteoporosis means “porous bones.” It results in fragile bones. The weakness of the bones puts those affected at a higher risk of fractures.
As the bones become thinner, even a minor fall or bump can cause a serious injury.
Middle-aged women are at the highest risk — however, men are also affected.
The main concern most people have when talking about osteoporosis is the high risk of bone fracture. A fracture is a complete or partial break in a bone.
It’s estimated that 50% of women and 20% of men over the age of 50 will have an osteoporosis-related fracture in their lifetime .
With osteoporosis, the most common bones affected are the hip, wrists, and spine. Fractures and breaks can lead to chronic pain and mobility issues.
Understanding the Definitions
- Cortical bone — the hard outside layer of all bones and makes up most of your skull and ribs.
- Spongy bone — occurs inside the vertebrae and the ends of the long bones, such as the thigh bones.
- Osteoblasts — specialized cells involved in producing new bones.
- Osteoclasts — specialized cells involved in breaking down bones.
- Bone density — the amount of mineral content in a bone.
Symptoms of Osteoporosis
There are no specific symptoms of osteoporosis — the first sign is usually a bone fracture. There are other symptoms, but these can be difficult to identify.
Other signs and symptoms may include:
- Back pain
- Collapsed or fractured vertebra
- Loss of height
- Stooped posture
- Lowered grip strength
Menopause & Osteoporosis
In osteoporosis, there is a thinning of the cortical bone and reduced bone density and structure in the spongy bone. Menopause is one of the main causes of the condition.
Bone tissue is continuously broken down and replenished. It’s a regular cycle, fluctuating on both a daily and monthly basis — affected by things such as time of day, diet, and season.
Specialist cells within the bones called osteoblasts and osteoclasts are essential for these fluctuations in healthy bones. From birth to adolescence, more bone is formed than broken down.
By the end of adolescence, bone growth has completed. By your mid to late 20s, peak bone mass has been achieved.
The sex hormones estrogen and testosterone have a major role in maintaining healthy bones in both men and women.
In menopause, as estrogen levels drop, the balance of hormones that were working to control bone density begins to fall apart. The result is an acceleration in bone loss. Women can lose up to 10% of their total bone mass within the first five years of menopause.
Risk Factors for Osteoporosis
- A family history of osteoporosis
- Previous bone fractures
- Age — people over 50 are at the highest risk
- Early menopause — before the age of 45
- Weight — being overweight is a major risk factor
- Vitamin D — important in the maintenance of bone tissue
- Calcium intake — calcium is a key mineral in bone architecture
- Lack of exercise — weight-bearing exercises directly lower the risk of osteoporosis
- Smoking (linked with osteoporosis)
- Alcohol intake — over three standard drinks per day increases the risk of osteoporosis 
- Medications — such as corticosteroid use
- Medical conditions — such as thyroid problems, celiac disease, chronic liver disease, kidney disease, or rheumatoid arthritis
- Conditions that affect the absorption of nutrients — such as Crohn’s disease, celiac disease, and other inflammatory bowel conditions
If osteoporosis is suspected, your doctor will most likely send you for a bone density scan.
This scan is used to measure bone mineral density (BMD). It is usually performed using a dual-energy x-ray absorptiometry (DEXA). This is a non-invasive process where, for 10 to 15 minutes, a machine passes over your body while you lie flat on a table.
The bone density scan will give you a T-Score and Z-Score, used to determine your risk of developing a fracture and whether further tests are needed.
According to the World Health Organization (WHO), your T-Score is classed as follows:
- -1.0 or above is normal bone density.
- Between -1.0 and -2.5 means you have low bone density or osteopenia.
- -2.5 or below is a diagnosis of osteoporosis.
The following procedures can also be performed to determine bone injury or fractures as a result of osteoporosis:
1. Bone X-Ray
Bone x-rays produce images of bones that aid in the diagnosis of fractured bones, which are sometimes a result of osteoporosis.
2. CT Scan
CT scans of the spine are used to assess alignment and fractures. They can be used to measure bone density and determine whether vertebral fractures are likely to occur.
3. Magnetic Resonance Imaging (MRI)
An MRI of the spine is used to evaluate vertebral fractures for evidence of underlying diseases, such as cancer, and to assess the newness of the fracture.
How is Osteoporosis Treated?
Depending on how severe your osteoporosis is and your risk of bone fracture, your doctor may recommend lifestyle changes to strengthen your bones.
Lifestyle changes can help to ensure both men and women take steps to prevent the risk of developing osteoporosis.
1. Lifestyle & Diet Changes
- Incorporate a varied diet with plenty of fresh fruit, vegetables, and whole grains
- Avoid smoking
- Reducing alcohol intake
- Limit caffeine
- Do regular weight-bearing and strength-training activities
- Ensure adequate vitamin D and calcium intake
However, if your osteoporosis is more advanced, lifestyle changes alone may not be enough to help you strengthen your bones.
Prescription medications are standard care in the treatment of established osteoporosis. Their purpose is to either increase the formation of new bone or slow down the breakdown process.
However, they each come with their own set of side-effects and risks.
2. Bisphosphonate Medications
Bisphosphonates encourage bone density by slowing the breakdown of cells. You can take them with a combination of vitamin D and calcium supplements.
Side-Effects of Bisphosphonates:
3. Selective Estrogen Receptor Modulators (SERMs)
SERMs mimic estrogen in the body, reducing bone loss and increasing bone formation.
Side-Effects of SERMs:
This is given via an injection under the skin twice a year. It slows down the breakdown of bone, resulting in higher bone mineral density and reduced fractures. It is often used as an alternative to bisphosphonates.
Side-Effects of Denosumab:
5. Hormone Replacement Therapy (HRT)
Doctors prescribe HRT for women during menopause when there is a drop in estrogen levels, increasing the risk of osteoporosis. However, HRT is no longer routinely recommended due to the increased risks with long-term use.
Side-Effects of HRT:
6. Testosterone Therapy
When testosterone levels are low in men, doses of testosterone are given by injection to improve bone density.
Side-Effects of Testosterone Therapy:
- Acne and oily skin
- Worsening of sleep apnea
- Increased risk of blood clots
- Increased risk of prostate abnormalities
- Enlarged breasts in men
- Decreased testicular tissue
- Increased aggression, mood swings
- Increased risk of heart disease and stroke (maybe)
Final Verdict: Using CBD for Osteoporosis
Osteoporosis can be a debilitating disease, and the fear of bone fracture can have a significant effect on one’s lifestyle and mobility.
While there is no cure, there is good evidence that CBD may be an effective treatment for osteoporosis by slowing down the progression of the disease and relieving pain.
These are very exciting times, especially as we look at CBD and the clinical research that’s still in its infancy regarding verifying its use in reducing bone loss and fracture.
Based on this information, CBD is seen as a safe, effective, all-natural therapeutic treatment for osteoporosis.
Everything You Need to Know About CBD Oil and Bone Health
The first written record of cannabis use dates back to 440 BC. That’s over 2000 years ago!
The Greek historian Herodotus tells how the Scythians, an ancient Siberian tribe, used hemp as part of their funeral rituals. They would place red-hot stones in a dish and add hemp-seeds to produce a vapor.
Now, if the Scythians lived in modern times, they’d be right on trend.
Hemp is a variety of the cannabis plant that’s rich in cannabidiol (CBD). So, CBD oil is derived from the hemp plant— and it’s becoming more popular by the day thanks to its potential therapeutic benefits.
These benefits have been at the center of a lot of research in recent years. In fact, studies show that CBD may relieve pain, anxiety, depression, and several other conditions. And some suggest it even supports bone health.
So with all the questions circulating about CBD and it’s potential benefits, we decided to dig into the most recent research to find out what we know— and don’t know— so far…
But first, what is CBD exactly?
What is CBD?
CBD is one of many naturally occurring compounds that come from the flower of the cannabis plant. These compounds are called “phytocannabinoids”, although this is often shortened to cannabinoids.
So, CBD oil is simply a concentrated liquid extracted from a plant!
Fun Fact: “Phyto” is a prefix that stands for “plant”, so “phytocannabinoids” literally means cannabinoids from plants.
CBD is the second most abundant phytocannabinoid after tetrahydrocannabinol (THC).
Now, THC and CBD both have therapeutic properties. But there’s one big difference between the two:
- THC is psychoactive meaning it causes the high associated with cannabis.
- CBD is non-psychoactive meaning it doesn’t cause a high.
In other words, CBD is non-intoxicating, but it still provides a wide range of potential therapeutic benefits. (A fact that explains it’s rising popularity!)
But why can this simple compound from a plant have such an effect on the human body? The answer lies in the endocannabinoid system…
What is the Endocannabinoid System?
All vertebrate species have an endocannabinoid system. It’s a crucial part of our biology that’s evolved over thousands of years. In large part, this system helps your body maintain homeostasis.
Homeostasis is like a balancing act. Your biological systems need to stay within a certain range to function properly. Your blood sugar levels shouldn’t be too high or two low. Your body temperature shouldn’t be too hot or too cold. And so on.
There are many functions like this throughout the body… and that’s why the endocannabinoid system is so widespread! (And why when a compound like CBD interacts with your system, you can experience diverse effects.)
Fun Fact: “Endo” is a prefix that stands for “within”, so “endocannabinoid” literally means cannabinoids from inside the body.
- Cannabinoid receptors: These receptors interact with both endocannabinoids and phytocannabinoids.
- Endocannabinoids: These are the cannabinoids your body makes itself.
- Enzymes: These enzymes are responsible for both creating and breaking down endocannabinoids once they’re done their job!
There are two main receptors called cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2). Recently, GPR55 has also been identified as a third cannabinoid receptor.
CB1 receptors are expressed mainly in the brain, spinal cord, and nervous system. CB2 receptors, on the other hand, are mostly found in peripheral tissues like your spleen and immune cells. And GPR55 is expressed in your brain and peripheral tissues.
Now, you can think of endocannabinoids as the “keys” and receptors as the “locks” in this system. By turning these keys, the system sends signals throughout your body and helps regulate many physiological functions.
These functions include pain perception, learning, memory, and appetite (to name just a few!). And as we’ll see in a moment, early research shows this system is involved in the bone remodeling process.
Fun Fact: The endocannabinoid system is actually named after cannabis, not the other way around! This is because the natural compounds in cannabis that interact with this system— phytocannabinoids— are what led to its discovery. But the endocannabinoid system itself existed long before we found out about cannabis.
The Research on CBD’s Potential Health Benefits
One of the first studies exploring the health benefits of cannabis was published in 1843 by John Clendinning. Clendinning presented 18 case studies where he treated patients with hemp. In the end, he found hemp had many therapeutic benefits like improving sleep and soothing anxiety.
Of course, Clendinning’s research wouldn’t be considered high quality by today’s standards. His study looked at a small sample, and he used a simple observational method. Yet, it does go to show that CBD has a rich medicinal history.
Since then, science has come a long way. And though modern research investigating CBD is still in its infancy, there are some interesting findings worth noting…
CBD Oil May Help Slow Bone Loss
A number of preclinical studies suggest the endocannabinoid system plays a role in bone metabolism. “Preclinical” means research that takes place before human trials to find out whether a treatment might be useful.
In other words, the evidence so far comes from cell culture studies and animal studies. If you’re a regular reader of the AlgaeCal blog, you’ll know that preclinical findings need to be taken with a grain of salt because they aren’t always applicable to humans.
That said, animal studies are useful because they can point us in the right direction. And some researchers think that when it comes to the endocannabinoid system, they’re pointing towards possible therapeutic strategies to deal with bone loss.
But how would this work?
Well, CB1 and CB2 receptors can both be found in your bone cells, including your osteoclasts (bone-clearing cells) and osteoblasts (bone-building cells). And GPR55 is expressed in your osteoclasts too.
Now, most studies on osteoporotic mice show that blocking CB1, CB2, and GPR55 receptors protects against bone loss. In other words, by blocking these channels, the mice in these studies increased their bone mass.
Researchers are hopeful they can harness this discovery to develop new anti-resorptive treatments. But this mechanism is problematic for several reasons…
As you may recall, CB1 and CB2 are also present on osteoblasts, your bone-building cells. So blocking these receptors may slow bone loss, but it also inhibits bone formation. And since it takes a lot longer to build bone than it does to break down bone, this will tip the balance in favor of bone loss over time.
That’s why researchers were most intrigued by the third cannabinoid receptor, GPR55.
A recent study showed that blocking this receptor in adult male mice reduced osteoclast activity and increased bone mass. Notably, the researchers found that blocking GPR55 didn’t interfere with bone formation. And of course, slowing bone loss without inhibiting bone building tips the balance in favor of increased bone density.
The researchers also found that cannabidiol (CBD) was effective at blocking this receptor. Remember the lock and key analogy? Well, CBD is like a “key” that deactivates GPR55. So based on this study, they concluded that CBD could be a tool to slow bone loss.
But once again, there’s a major issue with this conclusion… and with what blocking any of these receptors does!
Here’s the thing: slowing bone resorption may increase bone mass temporarily, but this strategy is inherently flawed.
There’s a reason your body breaks down bone. It’s getting rid of damaged or worn out bone to make way for new, strong bone. So, if you block this process, your bone density may increase… but really, you’re left with poorer and poorer quality bone that’s more prone to fracture in the long run!
Of course, it’s unlikely that taking CBD oil recreationally would have a major effect on your bones. However, it could be a problem if scientists leveraged this discovery to create a treatment for bone loss.
Because a treatment for bone loss targeting these receptors would likely just be another band-aid solution.
And slapping a band-aid on bone loss is not a good idea…
The best course of action is to address the root cause of the problem, and feed your body the nutrients it needs to build strong, new bone. In fact, three human clinical trials show that when you provide your body with 13 minerals and three vitamins, you can build brand new bone and reduce your risk of fracture!
CBD Oil Helps Relieve Pain
You may have heard stories of cancer patients using CBD to deal with pain. Or maybe you know someone first-hand who uses CBD oil to ease aching joints or to manage inflammatory bowel disease…
But is there research to back up this belief?
Well, a review of randomized controlled trials (RCTs) investigating the use of cannabinoids in the management of difficult to treat pain came to favorable conclusions. Researchers looked at several different cannabinoids, including CBD. They reported that in addition to having neuroprotective, antioxidant, and anti-inflammatory properties, CBD also works as an analgesic. (“Analgesic” simply means it relieves pain.)
They concluded that the use of cannabinoids to treat pain shows great promise.
Other studies investigating the use of CBD with THC in pain management have come to similar conclusions.
For example, in a review of medical cannabis in cancer pain management, researchers found that a combination of THC and CBD provided significant relief. But they cautioned that due to the limited number of studies and study subjects, more research is needed to determine how effective cannabis-based therapies really are.
In another study, researchers looked into whether an oromucosal spray containing THC and CBD helped patients with severe chronic pain. They looked at 800 patients and measured their pain at the end of 12-weeks based on nine-factors of symptom relief. In the end, they found that treatment with THC and CBD was effective at relieving chronic pain— especially neuropathic pain, which is caused by damage to the nervous system.
But since these studies looked at THC and CBD together, there’s no way of knowing whether the effects were due to one or the other cannabinoid.
As you can see, there are many limitations when it comes to the research on CBD and pain relief. So at this point, we can’t say anything definitive about the effectiveness of CBD for treating pain. And more quality research is needed to investigate this usage.
CBD Oil May Help With Sleep
Another common reason people use CBD oil is to help with sleep.
And there is some research to back this application. A recent analysis of clinical trials found that CBD did show a positive effect on sleep. Many of the studies reviewed suggested “cannabinoids could improve sleep quality, decrease sleep disturbances, and decrease sleep onset latency”. (That is, how long it takes to fall asleep!)
But it should be noted that this analysis had its limitations.
First off, most of the current research on CBD focuses on the treatment of chronic health conditions. So sleep wasn’t the main outcome being measured in these studies, and the measurements weren’t validated as rigorously as a main outcome might be.
What’s more, many of these studies had small sample sizes. And we can’t draw general conclusions from studies with small sample sizes.
So the research is interesting when it comes to CBD and sleep, but there’s still a lack of evidence to back this benefit.
Even though the evidence isn’t conclusive, it’s worth noting that getting adequate sleep is important for bone health! So it’s possible CBD oil could benefit your bones indirectly by helping you achieve higher quality sleep.
Is CBD Legal in the United States?
With all these potential health benefits, it’s no wonder CBD is gaining popularity. But despite this surge, many people are unclear on whether CBD is, in fact, legal.
And unfortunately, the answer isn’t cut and dry.
In the United States, federal law says that CBD oil derived from hemp is legal as long as it contains less than 0.3% THC. (Remember, THC is a psychoactive compound, while CBD is not.)
But state laws are another story. Most states haven’t changed their laws to align with federal regulations which is a big source of confusion for local authorities and residents alike.
What’s more, federal rules prohibit adding CBD to food products. Yet, there are states like Colorado that have legalized adding CBD to food for sale…
Suffice to say, the legal situation is hazy, and neighboring states might have very different laws concerning CBD than your state!
So even though legislation has come a long way, it’s best to exercise caution and check your local regulations before purchasing a CBD product.
Safety and Side Effects of CBD Oil
The popularization of CBD oil raises an important question, “Is it safe?”
And once again, the answer is a little complex. Here’s what the research tells us so far…
The first comprehensive review to look at the safety and side effects of CBD was conducted in 2011. Researchers looked at 132 animal and human studies where CBD was administered at varying doses and concluded that:
- It doesn’t cause catalepsy (a condition where your muscles go rigid and you lose sensation in the body).
- It doesn’t alter heart rate, blood pressure, or body temperature.
- Psychological and psychomotor functions aren’t affected.
- It’s non-toxic in cells and doesn’t affect food intake or gastrointestinal transit.
- Chronic use and doses of up to 1500 mg per day are well tolerated in humans.
A more recent review reported that in studies of epilepsy and psychotic disorder, CBD did have some side effects including tiredness, diarrhea, and changes of appetite and weight. But these side effects were mild compared to those of other treatments.
In the end, their conclusion was in line with the first review. They found that though CBD has a favorable safety profile, there are still knowledge gaps concerning its side effects— especially in the long-term.
So, more high quality human studies are definitely called for. Until that happens, we won’t have an in-depth understanding of the effects of chronic CBD use.
In addition, CBD sold online isn’t regulated by the FDA or any outside agency. What this means is the quality and purity of CBD products varies greatly. A label might say one thing about dose or concentration, but the reality could be vastly different.
In a study investigating the labeling accuracy of CBD sold online, researchers purchased and analyzed 84 products from 31 companies. They found that of the tested products, 26% contained less CBD than labeled and 43% contained more than labeled!
Although this study used a small sample, it does highlight the inaccuracies in the sale of CBD products, and the need for more rigorous manufacturing and testing standards.
So it’s little surprise the FDA cautions buyers to beware when purchasing CBD products.
Basically, the growth of the CBD industry outpaced both science and legislation. We still have a lot to learn about the effects of CBD, and regulations are needed to control the quality of the product on the market.
So if you’re interested in trying it, just make sure to talk to your healthcare professional first.
Finally, bear in mind that even though CBD is extracted from a plant, it’s not a natural supplement in the sense that we don’t have cannabidiol circulating in our bodies already. So, it’s best to think of CBD as you would any drug, and take the appropriate precautions. In other words, weigh the benefits against the potential side effects before making a decision.
Note that our Resident Bone Health Expert, Lara Pizzorno, did a thorough review of PubMed, the PDR, Up to Date, and the physician version of drugs.com, and found no interactions between CBD and any of the nutrients in AlgaeCal Plus, Strontium Boost, or Triple Power. So, you can take CBD oil with AlgaeCal products.
CBD Oil and Bone Health Takeaways
The CBD industry seemingly sprung up overnight. And like many young industries, it’s going through some growing pains.
CBD manufacturers have made some bold claims regarding the therapeutic effects of their products. But these claims are largely unsubstantiated by science and have landed them in hot water with the FDA.
The truth is there’s not enough high quality, long-term research on CBD yet to back its potential health benefits.
So if you’re interested in trying CBD, there are a few things you should keep in mind:
- Talk to your healthcare provider first, so they can advise you on possible interactions.
- Check your local legislation to ensure CBD is legal in your state.
- Make sure you choose a quality CBD product from a reputable company.
And remember, everybody is unique, so success with CBD oil may vary from person to person. So start small, listen to your body, and if it’s not for you, that’s perfectly okay too!
