My husband, is 63 yrs old, has recently had his yearly physical and passed with flying colors. He is taking Lisinopril 20 mg., multi-vit. and 2,000 units of Vit D 3 a day. He has noticed a little more frequent urination and we are sure it is his prostate, enlarging as is normal for men as they age. Is there any natural or herbal, OTC pill for this? Yes, he had his prostate checked and no problems.
