At the full 3-tablet daily dose, you're getting 345mg of elemental **Magnesium** — right in the clinical sweet spot (100–400mg) for supporting energy, muscle recovery, sleep quality, and heart function. Magnesium deficiency is extremely common, and this dose is enough to meaningfully close that gap.

The malate form absorbs well and is easy on your stomach, which matters if you're taking it daily. The malic acid component also feeds directly into your body's energy production cycle, making this form a particularly good fit if fatigue or muscle soreness is your main concern.

The catch is that each tablet only contains 115mg of elemental magnesium — about 29% of the upper clinical range. If you only take one tablet instead of the recommended three, you're getting minimal benefit. Stick to the full dose to get what the research supports.
