This refreshing, fizzy drink mix delivers fast-acting support to help you feel the power of CALM and work it into your day. Once combined with warm water, it fizzes and bubbles to life, transforming the citric acid, magnesium carbonate, and water into a highly absorbable Ionic Magnesium Citrate. It also delivers Magnesium Glycinate in ionic form for additional CALM support. This soothing cup of CALM is as much fun to make as it is to sip.*
