10 Benefits of Niacin
Niacin Benefit #2: Relieves Insomnia
Niacin can also be used to induce REM (rapid eye movement) sleep, thereby helping combat insomnia in some individuals. Vitamin B3 can work with the adrenal gland in secreting stress-reducing hormones, eventually reducing stress and anxiety, as well as increasing serotonin and melatonin.
Although this process helps the body relax, the mechanism behind why niacin helps with REM sleep is unclear. However, it is known that the essential amino acid L-tryptophan helps improve sleep and reduce stress due to its involvement with serotonin and melatonin production; L-tryptophan is then converted to niacin in the body.
