Fazit

Vitamin B6 may help support falling asleep faster, especially for those with low B6 levels, as it plays a key role in the body's melatonin production process.

31 studies with 3,623 participants, including 9 RCTs
About 55% of studies show positive effects on falling asleep
B6 is essential for converting tryptophan to serotonin and melatonin
May be most beneficial for people with insufficient B6 intake
