Each scoop delivers 200 mg of elemental **magnesium** from **magnesium lysinate glycinate chelate**, a premium chelated form known for high absorption and minimal digestive side effects. The suggested two scoops per day bring you to 400 mg, right at the top of the clinically studied supplemental range (100–400 mg). Magnesium is involved in hundreds of processes in your body, from energy production and muscle function to heart rhythm and bone health.

The glycinate chelate form absorbs efficiently through your intestines without the laxative effect that citrate or oxide can cause. The glycine component also supports relaxation and sleep quality, making this a good option if you take magnesium in the evening. The powder format dissolves in liquid, which can further improve absorption compared to compressed tablets.

Magnesium deficiency is extremely common — over half the population may not get enough, since standard blood tests don't reflect what's stored inside your cells. If you pair this with vitamin D, magnesium is required to activate it in your body; without enough magnesium, supplemental vitamin D stays largely inactive.
