For relaxation, muscle recovery, and sleep support, the full 2-teaspoon dose gives you 325mg of **Magnesium** as ionic magnesium citrate — well within the clinical range of 100–400mg. The directions suggest starting at half a teaspoon (about 81mg) and working up, which is practical since magnesium citrate can cause loose stools at higher doses.

The fizzing powder format dissolves in water and makes your daily magnesium feel more like a beverage than a supplement. Citrate is a well-absorbed form, though not quite as gentle on digestion as glycinate or bisglycinate at higher doses.

The serving size listed on the label is 1 gram (about half a teaspoon), which contains only a fraction of the full dose. To reach the 325mg shown on the panel, you need the full 2-teaspoon (4g) serving. Make sure you're reading the label carefully to know how much you're actually getting per scoop.
