What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

5-HTP, Valerian, and Magnesium are supported by moderate to strong evidence for promoting relaxation and mood regulation. Vitamin B6 and Calcium serve as essential cofactors in neurotransmitter synthesis. Overall, the ingredient profile is backed by established research, though the specific combination's synergistic effects have limited clinical documentation.
