Natural Vitality created CALM, the #1 selling magnesium supplement in the United States for over a decade — and the bestselling supplement in the natural products industry. CALM addresses one of the most widespread nutritional deficiencies in the modern population: magnesium, which is involved in over 300 enzymatic reactions and is essential for healthy stress response, sleep, muscle relaxation, and cardiovascular function. Natural Vitality uses a highly soluble ionic magnesium citrate that dissolves instantly in warm water, delivering magnesium in a bioavailable form that is easy on the digestive system. From Classic CALM powder to CALM Gummies, CALM Sleep, and CALM Energy, Natural Vitality has built an entire wellness ecosystem around the fundamental importance of magnesium in daily health.
