What Every Athlete Should Know About CBD

Science is racing to uncover more about CBD's potential for managing pain, anxiety, and more.

Expert Verified By: Dr. Mike T. Nelson

It’s legal now. It’s no longer on the World Anti Doping Agency’s prohibited list. And a new company seems to be launching every other day — is it time you tried cannabidiol?

Some athletes (and brands) are claiming that CBD is the new cure all that can address everything from headaches to sore joints to inflammation to sleep issues. “It’s a wonder drug with zero side effects and bro, it’s not even really a drug.” (It is a drug.)

Its explosion of popularity has left this a topic rife with myths and the fact that it only became legal over the counter in 2018 means that historically, it’s been tough to carry out studies on the stuff. What do we know, and what might we see in the future? We’ve spoken to a biochemist and two entrepreneurs in the space to learn more about the following topics.

What Is CBD?

It’s just one of at least 113 cannabinoids that have been identified in cannabis, but it’s one of the most studied and it can make up to 40 percent of the plant’s extract. Tetrahydrocannabinol, or THC, is the one that’s been traditionally coveted by those looking for the psychoactive effects of your standard spliff. (It’s the stuff that gets you high.) THC does have links with managing pain and certain medical conditions as well, but we’re focusing on the cannabinoid that’s federally legal and more strongly associated with some particular health benefits.

CBD is kind of like the fiber in a brownie or the antioxidants in chocolate: it’s not why most people usually consume them, but it seems to sneak in some benefits.

One of the main ways it interacts with the body is with our endocannabinoid system, a regulatory system that scientists named while trying to figure out how cannabis affects the body. We now understand it to be one of our most important physiological systems: it mediates inflammatory response, memory, hunger, learning, and cognitive function.

CBD is kind of like the fiber in a brownie or the antioxidants in chocolate: it’s not why most people usually consume them, but it seems to sneak in some benefits.

You can find cannabinoids in the plant but we also produce our own endocannabinoids, and while we initially thought this system mostly interacted with mood and pain, we’re now learning that their receptors are present in organs, connective tissues, glands, immune cells, and elsewhere.

So disruptions in our endocannabinoid system are perhaps not so surprisingly linked to a wide variety of ailments, and stimulating or otherwise manipulating it could be key to influencing a huge variety of disorders. This is why CBD has been linked to so many roles in the body.

CBD and Pain

When it comes to athletes, the area with the most potential benefit seems to be for managing pain and inflammation.(1) We definitely need more large, randomized studies here, but a few studies — most on mice, but some on humans — have found that by acting on certain cannabinoid receptors, CBD can exert analgesic or pain-relieving effects.(2)(3)(4)

“It actually acts as an antioxidant, and through that mechanism it’s anti inflammatory,” says Michael Mastell, a biochemist and strongman. “It acts on the TRPV1 receptor, the same receptor as capsaicin. The dosing scheme seems to be about 300 milligrams taken orally. In studies on cannabinoids in general, they can have detrimental effects on athletes but when they look at CBD specifically, it doesn’t have any negative effects.”

He adds that it’s typically not a great idea for athletes to use non steroidal anti inflammatory drugs — NSAIDs — to manage their pain for an extended period of time because it works through what’s called COX inhibition. The side effects for long term use can include digestive issues, insomnia, and headaches, but since CBD doesn’t work as a COX inhibitor it might hold more promise as a longer term solution to pain and inflammation.

“NSAIDs and paracetamol are great for addressing inflammation and chronic pain, but are essentially suppressants that make the brain feel less pain by producing certain enzymes,” says Austin Katz, the founder of Shea Brand, which produces CBD-based products. “Cannabinoids, on the other hand, essentially cut out the middle man by binding directly to receptors that are either located on the affected area or are responsible for controlling certain functions like pain, immunity response, and inflammation.”

Again, research on this is still in its infancy, but the evidence suggesting that CBD can help mediate inflammation also means that, indirectly, it may help with immunity.(5) It’s an indirect bonus for an athlete, but we all know that getting sick can really throw a wrench into a well designed strength program

CBD, Anxiety, and Sleep

Much has been written on the topic of CBD and mental health. Some evidence has suggested that it could help to reduce tremors in people with Parkinson’s disease and rodent studies have found it may help to reduce iron buildup in the brain, which is associated with memory deficits and neurodegeneration.(6)(7)

What if you’re not worried about these sorts of conditions and just want to sleep better or manage your anxiety? If you’re struggling with anxiety, first of all, you should see a qualified mental health professional. That said, CBD may exert some effects, here.

Research published earlier this year in the The Permanente Journal, for example, found that 25 to 75 milligrams of CBD helped to decrease anxiety and improve sleep in two thirds of its participants, and a couple of studies have even found that higher doses (300 to 600 milligrams) can reduce fear of public speaking among anxiety prone individuals.(8)(9)(10)

Mastell points to a study that found CBD to help rats perform better in a particularly stressful maze called an elevated plus-maze, which sounds unusual but it’s a well established type of experiment for figuring out how something might affect a person’s ability to handle stressful situations.(11)

“It seems to have a positive impact as anti anxiety effects, and there’s benefit there because some of these SSRIs, which are your typical depression drugs, can interfere with the sleep cycle,” he notes. “So it seems like you might not get as strong an anti-anxiety benefit as you do with those drugs, but you also don’t get the sleep problems. This has benefit to the athlete for helping their sleep cycle, but a lot of these benefits are in the secondary — you wouldn’t take it for (sleep).”

In short, there’s more evidence to suggest that it can improve sleep if your sleep is disturbed because of anxiety, not so much if you’re just a healthy individual who wants to sleep better.(12)

How to Take CBD

The recommended dosages vary a lot. Many experts suggest about 300 milligrams taken orally, but others have found benefit with as little as 20 milligrams, which is a relatively common dose in CBD supplements for athletes. It’s smart to start with small doses to assess your sensitivity.

While many recommend taking it orally, there’s also decent evidence that when applied topically — say, in an ointment to sore joints — it can also have an effect. Rodents with osteoarthritis experienced significantly improved symptoms this way in a 2017 study published in Pain, as did a study published the previous year on a rat model of arthritis.(4)(12)

“There is data that even if you take CBD sublingual, which is probably better as the first pass metabolism of the liver is very high, even then, taking it with food appears to increase bioavailability,” says exercise physiologist Dr. Mike T Nelson.(13) “Although that data is still extremely variable from one person to the next.”

“Topicals, sublingual oils, ingestible and vapes are all viable administration options, but you really need to know how to use them as tools respective to your specific needs, rather than cure-alls,” says Katz.

He recommends taking it sublingually for anxiety, topically for pain, and for headaches either topically on your temples and forehead, or through inhalation. Note that he considers these more as the optimal methods than the only viable ones. Start small and ask yourself how you feel every ten minutes until an hour hits.

“If the effects weren’t enough, up the dosage,” he suggests. “If it worked for you first try, then next time try lowering the dosage in pursuit of a more cost-effective dosage. As you do this enough times with various delivery systems, over time, you’ll develop an understanding of what works for you and how to get the most utility out of it.”

Masters Olympic weightlifter and CrossFit® athlete Hank Berger co-founded the athlete-focused CBD company Altrufuel in 2018 and emphasizes the importance of sourcing your products from the right places.

“One of the biggest mistakes is taking a product where you don’t know where it’s from — not everyone is following the standards that are set out,” he says. “There’s a really specific compliance you have to follow. The actual CBD or hemp has to be tested by a third party lab, so as soon as it comes off the flower it has to go to a lab and then if it has greater than 0.3 percent THC, then it’s really not acceptable for commercial use.”

This is especially important for competitive athletes. Note that first of all, while WADA has allowed the use of CBD, some federations may still have it on their prohibited list. But secondly, if you’re not using quality CBD, then it may contain enough THC to result in a positive test. Demand proof of quality from your suppliers.

Wrapping Up

The majority of the studies we’ve been citing here were on rodents — we really don’t have enough high quality studies on humans to make very  firm statements about CBD, not statements that have a complete consensus in the scientific community. But it’s pretty widely accepted that CBD holds real promise as a means for alleviating pain, and researchers are racing to further explore the potential benefits for anxiety, immunity, and other areas of health.

For now, we’re still in the early stages. But the radical shift in scientific opinion on CBD — from an illegal and maligned substance to a groundbreaking pain medicine — is nothing short of astounding.
