B الأدلة تدعم ذلك تجربة عشوائية واحدة على الأقل، مع نتائج متسقة في معظمها.بناءً على 5 دراسة (1 RCT) بمشاركة 50 مشاركًا إجمالاً. 3/5 دراسة تُظهر تأثيرات إيجابية.
الخلاصة
Vitamin B6 may play a role in supporting sleep through its involvement in melatonin production, but the direct evidence for insomnia is limited and preliminary.
- Only 5 studies with 50 total participants — evidence is preliminary
- B6 is involved in producing serotonin and melatonin, both important for sleep
- Genetic studies (Mendelian randomization) suggest a link between B6 and sleep behaviors
- More clinical trials with larger sample sizes are needed
