If you're looking for relaxation and sleep support, this delivers 420mg of **Magnesium** per scoop — the full RDA for men in a single serving, sitting at the top of the 100–400mg clinical supplement range.
The citrate form is a solid middle-ground choice — well absorbed and widely studied, though it can have a mild laxative effect at higher doses, which is worth knowing at 420mg. The powder format mixes into water or juice, making it easy to take before bed as part of your wind-down routine.
One consideration: the 420mg dose exceeds the 350mg supplemental upper limit set for magnesium from supplements specifically (the UL doesn't apply to food sources). If you're also getting magnesium from food and other supplements, you may want to start with one scoop and adjust based on how your digestion responds.
