HealthViva Calcium (With Vitamin D3 Magnesium) is a scientifically designed formulation to support and maintain strong bones in adults. Fortified with magnesium and vitamin D3, HealthViva Calcium ensures optimal absorption of calcium for healthy bones and lowers risk of fall and fractures in advancing years. In human body, calcium is required for bodily functions, such as such as nerve impulse transmission, muscle contraction, and blood clotting. Whenever there is less calcium in the blood, it leaches calcium from bones, the reservoir. In women peak bone mass is attained by the age of 25 and continues to decline thereafter. Hence, calcium supplementation is recommended to all women who find it difficult to meet dietary requirement of calcium. In women post menopause (cessation of periods) the hormone estrogen stops to secrete. As a result, women absorb less calcium from foods, which makes supplementation necessary. A consensus statement issued in 1994 by the National Institutes of Health (NIH) recommends 1500 mg of elemental calcium per day, obtained from dietary sources or supplements, for postmenopausal women. Moreover, older individuals synthesize less vitamin D from sunshine and adequate vitamin D is critical for optimal absorption of calcium from foods and supplements. Fortified with vitamin D3, HealthViva Calcium fills in the need gap in such individuals. Serving Suggestion: Take ONE tablet thrice daily with meals or as directed by your healthcare advisor
