CBD (cannabidiol) has exploded as a sleep supplement. It's in everything from gummies to pillow sprays. But does CBD actually help with sleep, or is it mostly marketing hype? The research is more nuanced than the ads suggest.
CBD is a compound found in cannabis and hemp plants. Unlike THC (the compound that gets you high), CBD is non-intoxicating. It interacts with your body's endocannabinoid system, which regulates mood, pain, appetite, and sleep.
The evidence is mixed. Here's what we know:
CBD's strongest effect is reducing anxiety. If your sleep problems are caused by anxiety, CBD may help by calming your mind. But CBD itself isn't a sedative; it works by removing a barrier to sleep (anxiety) rather than directly inducing sleep.
CBD has anti-inflammatory and pain-relieving properties. If chronic pain keeps you awake, CBD might help by reducing the pain. Again, it's not a direct sleep aid.
Whether you use CBD or not, a consistent sleep schedule is the foundation. Use our free Sleep Calculator to find your ideal bedtime.
In the US, hemp-derived CBD (containing less than 0.3% THC) is federally legal under the 2018 Farm Bill. State laws vary. CBD derived from marijuana is still federally illegal but legal in some states.
Start with 25 mg, 30-60 minutes before bed. If that doesn't work after a week, increase to 50 mg. Studies showing sleep benefits used 25-160 mg. Don't exceed 160 mg without medical supervision.
Yes, and many products combine both. They work through different mechanisms: CBD reduces anxiety and pain, while melatonin signals your brain that it's nighttime. There are no known negative interactions.
Pure CBD isolate (0% THC) won't. But full-spectrum CBD products can contain trace amounts of THC that may accumulate in your body over time. If you're subject to drug testing, use CBD isolate only.
