Formula OSX provides a high amount of calcium from microcrystalline hydroxyapatite along with magnesium and synergistic nutrients necessary to assist with osteoporosis and metabolic bone disease. A variety of factors can weaken bone tissue such as traumatic injury, inadequate calcium intake, aging and poor diet. Hydroxyapatite crystals, rich in highly absorbable calcium, anti-inflammatory mucopolysaccharides and proteins, assist to stimulate calcium uptake, which is particularly crucial during perimenopause and menopause.
