How to Have Good Dreams

While there's no research on whether or not taking B6 leads to more lucid dreams, the Internet is awash with anecdotal reports that it does—which, according to Dr. Barrett, makes good biological sense. "B6 is the co-factor our body uses to turn some of the amino acids we eat into the neurotransmitters that affect our dreaming," she says. To stop the vivid dreams, stop the supplements. But if you're looking to encourage dreaming, stay within the recommended amount of B6 daily—too much could cause nerve damage or numbness over time.
