Each serving gives you 200mg of **Magnesium** from lysinate glycinate chelate — a premium chelated form that absorbs well and is easy on your stomach. The label recommends two servings daily (four tablets), which puts you at 400mg, right at the top of the clinically studied supplemental range. At that intake, you're well-covered for goals like sleep quality, muscle relaxation, stress support, and energy production.

Magnesium deficiency is extremely common — estimated to affect over half the population — and standard blood tests often miss it. If you follow the full label dose, you're getting enough to meaningfully close that gap. The chelated form also means you're unlikely to experience the laxative effects that come with forms like citrate or oxide.

The tradeoff is pill burden: hitting 400mg means four tablets a day. If you only take one serving (200mg), you're still within the effective range but at the lower end — enough for general maintenance, though you may want the full dose if you're targeting a specific benefit like sleep or recovery.
