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-Dâ„¢ 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 ProstateEssenceâ„¢ or any other prostate supplement that does not provide more than 2000 IUs of vitamin D per day.*
