OsteoBlend Bone Support is a high-quality, moderate dose calcium supplement. The reason for the moderate dose is that the scientific guidelines for calcium intake are supposed to be 1000-1500 mg, depending on age, for our total day’s intake. This amount should come from diet and supplementation, not supplementation alone. On average women consume about 400-500 mg of calcium per day from food. By adding 1000-1500 mg of supplemental calcium to this, many women are taking too much calcium from supplements. The daily dose of 600 mg featured in OsteoBlend is calculated based on these considerations and holistic concepts. Select individuals who have low bone mineral density may need to supplement with additional calcium above what is in this formula.
