In the prostate gland, zinc serves as an important enzymatic cofactor. It also helps maintain prostate tissues. It does not help with urine flow, but is important to the overall health of the prostate. Zinc can be found in many multi-vitamin-mineral formulas or you can choose Zinc Picolinate 30 mg by Lindberg.
Saw palmetto extract has been prescribed for decades in Europe to treat mild to moderate prostate enlargement at a dosage of 160 mg taken twice a day using at least an 85% extract. Saw palmetto can be taken by itself as in Lindberg Saw Palmetto Extract, but is more popular as part of a complete prostate formula.
Nettle extracts or urtica diocia may work by inhibiting aromatase, which causes a number of other events that influence the frequency of nighttime urination. Nettle extracts are usually only found in complete prostate formulas.
Lycopene, green tea extract and the mineral selenium boost the value of a complete prostate formula since they deal with the long-term health of the prostate, not symptomatic relief that other ingredients may provide. Cancer research is ongoing with some of these supplements.
