Natural Vitality CALM® is an effervescent drink mix that helps to replenish magnesium levels and deliver fast-acting support to help you feel the power of CALM. Once combined with warm water, CALM fizzes and bubbles to life, transforming into a highly absorbable Ionic Magnesium Citrate. A soothing cup of Natural Vitality CALM is as much fun to make as it is to sip. This delicious watermelon formula is made with organic flavor and organic stevia leaf extract, and is a refreshing way to enjoy essential magnesium.
