There's only one FDA-approved CBD product — Epidiolex — that's used to treat seizures. Otherwise, the FDA doesn't regulate CBD products the way it regulates prescription medications. BUT it will send warning letters to companies if they violate rules surrounding CBD marketing and labeling. This usually happens if a company makes some wild claim about what its products can do. CBDistillery hasn't received any FDA warning letters. CBDistillery is U.S. Hemp Authority-certified though, which is currently the best certification you can get in the CBD world.
