Natural Vitality MaxCalm, also known as the anti-stress drink, is a multi-award-winning magnesium supplement. It helps restore the body’s magnesium levels while providing key nutrients for calcium assimilation simultaneously. Calcium excites nerves while magnesium calms them down—calcium makes muscles contract while magnesium is necessary for muscles to relax. Calcium is needed for blood clotting, but magnesium keeps the blood flowing freely. Natural Vitality Calm helps keep these two nutrients in proper balance so your body can function optimally.
