If you're after relaxation, sleep quality, and muscle function support, the full 2-teaspoon serving delivers 350mg of **Magnesium** as ionic magnesium citrate — near the top of the clinical supplemental range (100–400mg). The brand recommends starting low at half a teaspoon and building up, which is wise since citrate forms can affect digestion at higher amounts.
The unflavored version keeps your ingredient list minimal — just citric acid and magnesium carbonate alongside the magnesium citrate. No sweeteners, no added flavors. That makes it easy to mix into any beverage without changing the taste significantly.
The directions suggest splitting your daily amount into 2–3 portions throughout the day, which improves absorption since your body can only take in so much magnesium at once. If you're taking the full 350mg in a single serving, you may absorb less and experience more digestive effects than if you divide it up.

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.
With or without food
Space it a couple of hours from Iron and Calcium
On the label
