Mild non-acidic vitamin C Citrus bioflavonoids Calcium

Vitamin C 500 Complex is a pure, non-acidic vitamin C formula combined with naturally-occurring bioflavonoids. Unlike ordinary products, this formula’s vitamin C is uniquely non-acidic and therefore gentle even to the most sensitive stomach. This special formula promotes the greatest utilization of vitamin C without the stomach discomfort, loss of potency and rapid nutrient loss associated with ordinary ascorbic acid. Vitamin C is a powerful antioxidant that protects numerous body tissues and systems, including our immune, skeletal and circulatory systems, along with our heart, brain, liver, skin and eyes. Vitamin C is readily depleted by stress and although abundant in the healthiest of foods, it is sadly lacking from the typical American diet, which is why it has become among the most popular separate supplements in America. The calcium ascorbate form of vitamin C in this formula also provides a bonus of 50 milligrams of super-soluble, easily absorbed Calcium. It also comes with natural Citrus Bioflavonoids that are present in most Vitamin C rich foods.

Our Vitamin C 500 Complex also comes in small, soft, easy-to-swallow capsules that are guaranteed gentle even to sensitive stomachs.

Contains no additives or common allergens Contains no milk, soy, yeast, corn, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
