**Magnesium** at 400mg per serving hits the top of the clinically studied supplemental range (100–400mg), giving you a full effective dose for supporting energy production, muscle function, sleep quality, and stress resilience. The citrate form absorbs well and is one of the better-studied magnesium forms, though it can have a mild laxative effect at higher doses — something to be aware of if you have a sensitive stomach.
Magnesium deficiency is estimated to affect over half the population since standard blood tests don't reflect what's stored inside your cells. At this dose, you're well-positioned to close that gap. The product touches a wide range of health areas — from heart and bone support to mood and brain function — making it a versatile single-mineral supplement.
The main consideration is that each serving requires 3 capsules. If you prefer fewer pills, you'd need to weigh whether splitting the dose across the day works for your routine — which also helps with absorption since magnesium is better utilized in smaller amounts.
