BioStacksWhy Vitamin B6 for Sleep
For sleep support, Vitamin B6 is a supporting ingredient backed by research. Active form is pyridoxal-5'-phosphate (P5P), a coenzyme involved in over 100 reactions including neurotransmitter synthesis and amino acid metabolism. Standard pyridoxine must be converted to P5P in the liver, while P5P supplements bypass this step.
What dose to look for
Clinical studies typically use 25–100 mg of vitamin b6. Common B-complex dose; UL is 100 mg/day. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
What form to look for
Avoid pyridoxine — must be converted to active p5p. For best results, choose pyridoxal-5-phosphate (p5p).
