You're getting 420mg of **Magnesium** per capsule in bisglycinate form — one of the best-absorbed forms available, and gentle on your stomach. A single capsule already meets the full adult RDA (310–420mg), and the label suggests up to three daily, which would put you well above the supplemental upper limit. For most people, one capsule is plenty to support muscle relaxation, energy production, and sleep quality.

**Vitamin B6** is included at 5mg to help your body absorb and transport magnesium into cells — a well-studied synergy. However, it uses pyridoxine rather than the active P5P form, meaning your body needs to convert it before use. **Taurine** at 200mg is a nice addition for cardiovascular and cellular support, but falls well short of the 1,000–3,000mg range used in clinical research.

The main caveat is the taurine dose — at 200mg, you're getting about 20% of the minimum studied dose, so don't rely on this product for taurine's specific benefits. The magnesium itself, though, is solidly dosed and well-formulated.
