When it comes to finding ways to promote strong and healthy bones, Swanson Ostivone is a great place to start. Ostivone, which is the commercial name for a substance known as ipriflavone, is commonly found in alfalfa and soy plants. A non-hormonal nutrient, Ostivone is popular among people who are looking for a supplement that will support bone development. Research suggests that when an Ostivone ipriflavone supplement is combined with calcium, it may help to generate new bone cells.
