Each capsule delivers 125mg of **Magnesium** in the bisglycinate form — well-absorbed and gentle on your stomach. That's enough to put you at the low end of the clinical supplemental range (100–400mg), but if you're targeting sleep, stress, or muscle recovery, you'd likely want 2–3 capsules daily to reach the 250–400mg range where most benefits show up in research. Magnesium deficiency is extremely common, estimated to affect over half the population, so even one capsule adds meaningful support.

The small amount of **Vitamin C** (25mg as ascorbyl palmitate) is there as an antioxidant preservative, not a therapeutic dose — you'd need ten times that to enter the clinical range. Don't count on this product for vitamin C support.

With 180 capsules in the bottle, you have flexibility to adjust your daily dose based on your needs. At 2–3 capsules per day, you're looking at a 2–3 month supply and landing in the sweet spot for energy, muscle function, and relaxation support.
