Liquid Target-Mins Calcium-Magnesium with Vitamin D3 Complex Country Life offers the unique Target-Mins delivery system for increased effectiveness of mineral supplementation. First, we use a complex of free form amino acids combined for increased absorption. Second, we use not only a 2 to 1 ratio of Calcium to Magnesium, but we also use a 2 to 1 ratio of Calcium to Phosphorus. In a clinical study at Creighton University by Dr. Haney, it was demonstrated that for every 1,000 mg of Calcium consumed as a supplement, your body requires 500 mg of added Phosphorus for proper utilization. Third, we add vitamin D3, which has been shown to support proper regulation of the bodys Calcium/Phosphorus ratio and activate osteoblast function to support healthy bone structures. This is all combined scientifically to ensure optimal support for bone health.** Directions: Take one cap (1 fl. oz.)(29.59 mL) daily or as directed by a health care professional.
