CBD

A widely sold plant compound with a regulatory status most sites don't mention

Not psychoactive (unlike THC)
One real FDA-approved medical use
Important: These statements have not been evaluated by the FDA. This information is not intended to diagnose, treat, cure, or prevent any disease. Always consult your physician before starting any supplement.
Regulatory status: In January 2023, the FDA concluded that CBD does not fit the legal definition of a dietary supplement under the FD&C Act, because it's the active ingredient in an FDA-approved drug (Epidiolex) that entered clinical trials before CBD was sold as a supplement. This is different from state-level hemp legality — it means the FDA doesn't consider CBD products legally marketable as dietary supplements, and it declined to create a new pathway that would change that. We're including this page because CBD is extremely commonly searched and sold anyway, and think you deserve to know this before anything else.
If you take any prescription medication: CBD inhibits several liver enzymes (including CYP3A4 and CYP2C19) that metabolize a wide range of common drugs, including blood thinners, some antidepressants, and antiepileptics. It also carries a dose-dependent risk of liver enzyme elevation. Talk to your doctor or pharmacist before combining CBD with any medication -- this is one of the more genuinely interactive ingredients covered on this site.
Overview

CBD (cannabidiol) is one of over 100 compounds found in the cannabis and hemp plant. Unlike THC (tetrahydrocannabinol), CBD is not psychoactive -- it doesn't produce a "high." That distinction is real and well established, and it's the main reason CBD became so widely available after hemp (cannabis with under 0.3% THC) was federally legalized for cultivation under the 2018 Farm Bill.

What most CBD product pages don't tell you: separately from that hemp-legalization question, the FDA has concluded CBD does not meet the legal definition of a dietary supplement. That's a genuinely important piece of context most sites skip entirely -- see the regulatory callout above, and the FAQ below, for exactly what it does and doesn't mean.

Potential Benefits

The One Clear FDA-Approved Use

Epidiolex, a purified prescription CBD oral solution, is FDA-approved for seizures associated with Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex in patients 1 year and older. This is a precisely dosed pharmaceutical drug, not a retail supplement -- but it's the strongest, clearest evidence base CBD has.

Anxiety (Real Signal, Still Limited)

A 2024 meta-analysis of 8 studies (316 participants) found a significant reduction in anxiety with CBD across generalized anxiety, social anxiety, and PTSD. The authors were upfront that the finding rests on a limited number of small trials and needs more research before it's considered settled.

Not Psychoactive

CBD does not produce intoxication or a "high" the way THC does. It interacts with the endocannabinoid system differently, which is why it's marketed for calm and stress support rather than any recreational effect.

Acute Situational Anxiety (Small Study)

A small 2011 trial gave a single 600mg dose of CBD to people with social anxiety disorder before a simulated public-speaking test and found it reduced anxiety compared to placebo. It was a one-time, single-dose study in 24 people -- suggestive, not proof of how daily use performs.

Typical Dosage
No Standardized OTC Dose
Varies widely
Because CBD isn't FDA-regulated as a supplement, there's no official dosing guidance -- product concentrations and labeling accuracy vary a lot between brands
Studied Ranges
Single doses of 300–600mg
Used in acute anxiety research; Epidiolex uses precise, weight-based mg/kg dosing under a doctor's supervision
Pro Tips
  • Look for a third-party Certificate of Analysis (COA) before buying -- product content isn't FDA-verified
  • Start low and go slow; there's no official dose to anchor to
  • Never combine with medications without talking to your doctor or pharmacist first
  • If seizures are the reason you're interested in CBD, ask your neurologist about Epidiolex specifically
Research Snapshot: Strong for Seizures, Promising-But-Early for Anxiety

The seizure evidence behind Epidiolex is genuinely strong -- large, controlled trials led to full FDA drug approval. The anxiety evidence is a different picture: a 2024 meta-analysis found a real, statistically significant effect across 8 studies and 316 participants, but the authors explicitly cautioned that the sample is still small and more trials are needed before treating it as settled. That's a meaningfully different confidence level than the seizure indication, even though both get marketed under the same "CBD" label.

How CBD Compares

Ingredient Best For Key Difference
CBD Stress, Anxiety (Early Evidence) Not FDA-recognized as a supplement; real drug interaction risk
Ashwagandha Stress, Cortisol Legally a dietary supplement; larger, more consistent human trial base
L-Theanine Calm Focus, Mild Relaxation Non-sedating; works well alongside caffeine
Passionflower Anxiety, Sleep Onset Legally a supplement; comparable RCT evidence to a benzodiazepine for GAD

These are the most common comparisons our customers ask about in-store.

Frequently Asked Questions
Is CBD legal?
It's complicated, and "legal" isn't quite the right question. Hemp-derived CBD (under 0.3% THC) is federally legal to grow and sell as a hemp product under the 2018 Farm Bill. But separately, the FDA has concluded CBD does not meet the legal definition of a dietary supplement under the Food, Drug & Cosmetic Act, because it's the active ingredient in an FDA-approved prescription drug (Epidiolex) that was already in clinical trials before CBD supplements existed. So CBD products are widely sold at retail, but the FDA says they shouldn't legally be marketed or labeled as dietary supplements — and as of 2023, the FDA has said it will not create a new regulatory pathway to change that without Congress.
Will CBD get me high?
No. CBD (cannabidiol) is not psychoactive in the way THC (tetrahydrocannabinol) is — it doesn't produce a "high." They're both compounds found in the cannabis/hemp plant, but they act differently in the body. Products should list their THC content; hemp-derived CBD products are required to test under 0.3% THC, though third-party lab testing is the only way to actually confirm what's in a given product, since the FDA doesn't regulate CBD supplement labeling the way it does actual dietary supplements.
Can I take CBD with my medications?
Talk to your doctor or pharmacist first — this is a real interaction risk, not a formality. CBD inhibits several liver enzymes in the cytochrome P450 family (including CYP3A4 and CYP2C19) that metabolize a wide range of common medications, including blood thinners like warfarin, some antidepressants, and antiepileptic drugs. It can also cause dose-dependent liver enzyme elevation, which is why Epidiolex (the FDA-approved CBD drug) requires liver function monitoring. This is one of the more genuinely medication-interactive ingredients on this site.
