Overview: MapleLife® Pure Vegan Calcium is a naturally sourced, plant-based, naturally available calcium supplement. Our calcium comes from Red Algae, a “live” source that is more readily absorbed. Sustainably harvested in the pure, frigid waters off the coast of Iceland, our calcium contains high amounts of natural, easily absorbed plant calcium. In addition, plant calcium can help maintain the slightly alkaline pH of blood, preventing bone calcium loss associated with an acidic blood pH. In addition to calcium, red algae also contains magnesium, iron, zinc, selenium, boron, copper, and dozens of other trace elements, as well as the most powerful antioxidant to date – astaxanthin. Our red algae is milled from the whole plant, with nothing else added. It is Non-GMO, Kosher, Halal, and certified Organic. Ingredients: Medicinal Ingredients: (per tablet) Calcium (Calcium Carbonate from Red Algae - whole) 200 mg Directions: Adults: Take 1 tablet 1-3 times a day with food, or as directed by a health care professional.
