Calcitriol + Calcium citrate + Zinc Sulphate Monohydrate + Methylcobalamin + L-Methyl Folate + Boron + Magnesium Oxide is a combination of seven nutritional supplements. Calcitriol is a synthetic Vitamin D that regulates the absorption of calcium in the body and strengthens the bones. Calcium citrate increases calcium depositing in the bones which increases the density of the bones to them stronger. Zinc Sulphate Monohydrate helps to fulfill the zinc deficiency in the body for proper growth and development. Methylcobalamin is an active form of Vitamin B 12.
