Studies show that vitamin D is crucial for prostate health. Yet only one in ten Americans get the amount of vitamin D that research suggests is optimal for prostate health. With 4000 IUs of vitamin D3 and potent levels of green tea extract, DIM, genistein and lycopene, Prostate-D is a wondrous prostate support system. It is not designed to offset prostate enlargement, but may help such problems from occurring. It may be used with any multiple, or with ProstateEssence or any other prostate supplement that does not provide more than 2000 IUs of vitamin D per day.
