What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

This formula combines B vitamins and L-5-HTP, which have moderate evidence for supporting neurotransmitter synthesis and mood regulation. Chinese Skullcap root extract is included for its potential calming effects, though clinical evidence for its efficacy in this context is more limited. The ingredient profile maintains a high safety rating.
