Formulation Notes

A balanced combination of calcium, magnesium and zinc. Minerals must dissolve before they can be absorbed. Formula 817 is formulated to dissolve rapidly and completely for maximum absorption. Regular exercise and a healthy diet with enough calcium helps all women approximately 11 to 35 years of age maintain good bone health and may reduce their high risk of osteoporosis later in life. For persons with a family history of osteoporosis, menopausal women, or elderly men and women, adequate calcium intake is linked to reduced risk of osteoporosis through the mechanism of slowing the rate of bone loss. Adequate calcium intake is important but daily intakes above 2000 mg are not likely to provide any additional benefits.
