Osteo Support contains everything you need to help support normal bone health, including 1200 mg of calcium, 200 IU of Vitamin D, and 200 mg of Ostivone. Ostivone is a relatively new raw ingredient that has been shown to increase the effectiveness of calcium supplements. Osteo Support also contains Soylife, which provides standardized levels of isoflavones. Soylife is the brand used in several studies that have shown these isoflavones to be effective in preventing osteoporosis.
