* 1,000 mg Calcium. * 500 mg Magnesium. * 400 I.U. Vitamin D3. Country Life offers the unique Target-Mins delivery system for increased effectiveness with mineral supplementation. First, we use a complex of free form amino acids and organic acids combined for increased absorption. Second, we use not only a 2 to 1 ratio of Calcium to Phosphorus. A clinical study has demonstrated that a 2 to 1 ratio of Calcium to Phosphorus is key for proper mineral utilization, and Phosphorus plays an important role in bone structure. Based on these proven ratios, this product contains 1,000 mg of Calcium, 500 mg of Magnesium, and 500 mg of Phosphorus. Third, we add Vitamin D3 which has been shown to support proper regulation of the body's Calcium/Phosphorus ratio and activate osteoblast function to support healthy bone structures. This is all combined scientifically to ensure optimal support for bone health.*** Suggested Use: Take one cap (1 fl oz) (29.59 ml) daily or as directed by a health care professional.
