You're getting 200mg of **Magnesium** per serving in the bisglycinate chelate form — a well-absorbed option that's gentle on your stomach and unlikely to cause the GI issues common with cheaper forms like oxide. At 200mg, you're squarely within the clinical supplemental range (100–400mg), making this a solid maintenance dose for sleep, muscle relaxation, and stress support.

Magnesium deficiency is estimated to affect over half the population, and blood tests often miss it because serum levels don't reflect what's stored in your cells. If you're supplementing proactively, this dose covers the gap for most people without approaching the 350mg upper limit for supplemental magnesium.

If you're targeting a specific goal like sleep quality or muscle cramps, you may want to work toward the higher end of the clinical range. At one serving daily, you have room to increase to two servings (400mg) without exceeding safe limits — the bisglycinate form is well-tolerated even at higher intakes.
