Studies show that Vitamin D is crucial for strong bones. Yet, only one in ten Americans get the amount of Vitamin D that research suggests is optimal. With 2000 IU’s of Vitamin D3 and potent levels of Ipriflavone, Silica and Ionic Trace Minerals, Bone-D™ is perhaps the world’s best bone support system. It can be used alone, or with Ionic-Fizz™ Calcium Plus or any other high quality calcium/magnesium supplement (calcium should never be used with equal levels of magnesium). It can also be used with any multiple that does not provide more than 4000 IU’s of Vitamin D per day.
