What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

This formula combines magnesium and amino acids like L-theanine and L-glycine, which have moderate to strong evidence for promoting relaxation and improving sleep quality. L-tryptophan and 5-HTP serve as precursors to serotonin and melatonin to support sleep onset. Research generally supports these ingredients for sleep regulation, though overall evidence coverage for this specific blend is limited.
