Quote from
Lars' Dreaming FAQ
Melatonin is a neurotransmitter/hormone that is only active during sleep. It is being
metabolized when you fall asleep from Serotonin, a neurotransmitter that is being metabolized
from the amino acid Tryptophan. Melatonin increases non-REM sleep and makes it easier for you
to fall asleep. But it has also an interesting rebound effect that gives more frequent and
vivid dreams. The vividness might even give you a lucid dream.
The amino acid Tryptophan can be metabolized into Serotonin and Niacin (B-3). Vitamin B-6
promotes this conversion.
Taking Niacin or Nicotine patches will increase the Serotonin
production. The more Niacin you take, the more Serotonin is produced and more Melatonin is
metabolized. Calcium and Magnesium promotes Serotonin production as well. Zinc is in every cell
of the body and is a part of over 200 enzymes, so Zinc supplements may increase REM-sleep, too.
