Manganese is a mineral salt that is found in several foods including nuts, legumes, seeds, tea, whole grains, and leafy green vegetables. It is considered an essential nutrient, because the body requires it to function properly. Manganese is used for prevention and treatment of manganese deficiency, a condition in which the body doesn’t have enough manganese. It is also used for weak bones (osteoporosis), a type of “tired blood” (anemia), and symptoms of premenstrual syndrome (PMS). Manganese is sometimes included with chondroitin sulfate and glucosamine hydrochloride in multi-ingredient products promoted for osteoarthritis.

Zinc Ascorbate can be used as a dietary supplement and as a nutrient. Zinc is an important antioxidant nutrient. It is necessary for protein synthesis, wound healing, for blood stability, normal tissue function, and aids in the digestion and metabolism of phosphorus. It also governs the contractility of muscles and maintains the body’s alkaline balance. Zinc ascorbate has superoxide dismutase-like activity and in vitro antimicrobial activity against Staphylococcus aureus and Escherichia coli. Zinc ascorbate may be effective for acne treatment. Zinc ascorbate inhibits the growth of P. acnes (MIC, 640 ug/mL).

Magnesium ascorbate is a non-acidic buffered form of Vitamin C and a source of the essential mineral Magnesium. The in vitro model system consisted of the isolated section of rat small intestine. The sources of magnesium ion (Mg2+) were magnesium chloride, magnesium sulphate, magnesium acetate, magnesium lactate, magnesium hydrocitrate and magnesium ascorbate. Magnesium ions from magnesium ascorbate were absorbed after the first 15 minutes to the highest extent of all salts, but after 120 minutes their absorption was the smallest of all. The use of magnesium ascorbate in food supplements may lead to an additional exposure to vitamin C and Magnesium.
