Scientific Background – Peer-Reviewed Context

Magnesium is an essential mineral involved in a wide range of biochemical processes, while L-Theanine is a naturally occurring amino acid commonly found in tea leaves and studied for its unique interactions with relaxation pathways. Combination products like Magnesium plus L-Theanine are widely referenced in nutritional science discussions for support within evening routines or general calm focus.

Magnesium’s role in metabolism and nervous system function is well documented (Magnesium Overview – PubMed).

L-Theanine’s presence in botanical nutrition and its biochemical interactions have been explored in peer-reviewed literature (L-Theanine Research – PubMed).
