You're getting 300mg of **Magnesium** as citrate — solidly within the 100–400mg clinical range and enough to support muscle relaxation, stress reduction, and sleep quality. The powder format dissolves in water for easy absorption, and citrate is a well-absorbed form, though it can have a mild laxative effect at higher doses.

The formula adds **L-Theanine** and **GABA** at 100mg each. L-Theanine promotes calm without drowsiness, but the most-studied single dose for relaxation is 200mg — so you're getting half of that. GABA's ability to cross the blood-brain barrier when taken orally is still debated in the research, and the clinical evidence for supplemental GABA remains limited.

The magnesium dose is the real strength here. If you're taking this primarily for relaxation or sleep, the L-Theanine is a nice addition but falls short of the dose used in most studies — you'd get more from it at 200mg.
