Calcium does not function alone but rather works synergistically with other nutrients such as magnesium and zinc to deliver the most benefits. 500 mg of magnesium provides the widely popular 2:1 ratio of calcium to magnesium. Zinc plays an important role in the development of bone structure. 1000 IU of Vitamin D works with phosphorus to help support calcium in the blood. Glutamic Acid is an amino acid that aids in the absorption of calcium. Xylitol is naturally found in many fruits and vegetables and helps to support overall oral health.Other products from HerbsPro
