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.

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
Recommended use for adults: We suggested starting out with a half teaspoon (1 g) of Natural Vitality CALM powder, and gradually increasing to 2 teaspoons (4 g) daily. Directions: Start by placing the desired amount of powder into a cup or mug, add 2-3 ounces of warm water, and let your drink fizz. Stir the drink until the powder is completely dissolved, then fill the remainder of the cup with warm or cold water. Pour, fizz, mix, drink
