For relaxation, sleep support, and muscle recovery, this powder delivers 350mg of **Magnesium** from ionic magnesium citrate per 2-teaspoon serving. That puts you near the upper end of the clinical supplemental range (100–400mg).
Magnesium citrate is well absorbed and has decades of research behind it. The liquid format (you dissolve the powder in water) allows your body to start absorbing the magnesium quickly. With 113 servings per 16oz container, this offers good value if you're using it daily.
The tradeoff with citrate at this dose is digestive tolerance. At 350mg, some people experience loose stools — especially when starting out. If that's you, halving the serving and building up over a week or two is the standard approach. Glycinate-based magnesium products tend to be gentler at equivalent doses.

How to Take It
Best taken in the evening
Magnesium citrate pulls water into the bowel — mildly laxative at higher doses. Evening suits that; split the dose or switch to glycinate if it's too much.
