You're getting 300mg of **Magnesium** per scoop — right in the upper range of clinical supplemental doses (100–400mg) and well-positioned for stress reduction, sleep support, and muscle relaxation. The citrate form absorbs significantly better than oxide and dissolves easily in water, which makes this powder format particularly practical for hitting a solid dose without swallowing multiple capsules.
**Magnesium** deficiency affects an estimated half the population, and standard blood tests often miss it because serum levels don't reflect intracellular stores. At 300mg, you're close to the 350mg supplemental upper limit, so one scoop daily is the sweet spot — stacking this with other magnesium-containing supplements could push you over.
The citrate form does have a mild laxative effect, which is worth knowing if you have a sensitive stomach. If your primary goal is sleep or stress support specifically, glycinate or threonate forms may offer more targeted benefits — but for broad magnesium repletion at a clinically meaningful dose, this delivers.
