Formulation Notes

Contains Phosphorus and now 4x more vitamin D

Why is Phosphorus important? According to recent studies, consuming calcium with phosphorus is more effective at building strong bones than consuming calcium alone.

If you are among the 50 million American women who don't obtain the daily RDI for phosphorus from a balanced source in their normal diet... Take Posture-D, the only leading calcium supplement that delivers the ratio of calcium to phosphorus found in healthy bones.

Why has Vitamin D been increased to 500 IU per caplet? Vitamin D is extremely important in helping your body absorb calcium. Recent studies have shown that Vitamin D has other important benefits such as maintaining breast, colon and cardiovascular health. Many of us don't get enough sun exposure or eat foods sufficiently rich in Vitamin D, so now two caplets of Posture-D provides 1000 IU of Vitamin D.
