Cal-Plus is a comprehensive bone formula that promotes bone strength and density. Cal-Plus balances 650 mg of calcium citrate and 650 mg of magnesium citrate, 500 mg of silica, along with 200 mg of New Zealand bovine microcrystalline hydroxyapatite (MCHA), natural vitamin K-2 (MK-7), important synergistic nutrients and trace minerals designed to support bone strength, flexibility, remineralization, and joint health. Cal-Plus's unique formula with natural vitamin K-2 (MK-7) assists in directing calcium to the bone for remineralization. Silica in Cal-Plus's formula supports bone flexibility and strength, paired with a balanced ratio of calcium to magnesium, MCHA, and trace minerals, give the added support the body needs to maintain healthy bones and comfortable joints. The trace minerals boron, vanadium, and iodine were selected specifically for their contribution in assisting with the calcium utilization and remineralization processes. Betaine HCL provides the acid environment needed for calcium absorption. The Western Diet is deficient in many important minerals and trace minerals. Trace minerals aid in everything from healthy blood, hormone levels, and yes - healthy bones and teeth!
