Nature's Answer Plant Based Magnesium 500mg Vegan Capsule For Bone & Muscle Health are derived from red algae that naturally grows in pristine Iceland Arctic waters. Magnesium is a vital mineral that plays a role in multiple processes in the human body, including muscle function, bone development and vision health. Due to difficulty in reaching the RDI for magnesium from food sources alone, supplements are increasingly being used. Pure Marine Magnesium is a natural remedy which will help to support optimum nerve and muscle function. Magnesium for this supplement is sourced naturally from pure sea water and is one of the seven essential macrominerals we need for our bodies to function healthily. Aquamin's Red Algae and Seawater Marine Calcium, Magnesium and Multi-Mineral complex supplies bio-active calcium, magnesium and 72 other trace minerals. Untouched by the industry, the warm waters of the gulfstream meet the cold clean waters of the arctic and the perfect conditions exist for red algae to build up. The Aquamin'1s unique matrix of trace minerals works synergistically to give a powerful boost to magnesium's bioactivity. Magnesium derived from a marine-derived multimineral product is bioavailable to a significantly greater degree.
