This formula combines magnesium, L-theanine, and GABA, which are supported by moderate evidence for promoting relaxation and sleep quality. Valerian root and 5-HTP are also included to support sleep onset, though research on these specific extracts varies in strength. The ingredient profile is generally recognized as safe for most healthy adults.
