Copper
Copper is needed to absorb and utilize iron. Copper supplementation is usually due to symptoms of deficiency (anemia, osteoporosis, and neutropenia, a blood disorder), or with zinc supplementation, as zinc interferes with copper absorption. See ‘Zinc’ below. Damiana Damiana has been used in folk medicine for centuries, traditionally in Mexico as a mild male aphrodisiac. Results of a few small laboratory studies suggest that damiana may have some slight ability to widen blood vessels – an effect that may provide some ED relief. Damiana is also used for inability to achieve orgasm in women. Damiana appears to be safe at the recommended dosages. However, it contains low- levels of compounds similar to cyanide, so excessive dosages may be dangerous. Safety of damiana in young children, pregnant or nursing women, or those with severe liver and kidney disease is not established. The only common side effect is mild digestive distress. Dehydroepiandrosterone (DHEA) DHEA is the most prevalent of the hormones produced by the adrenal glands. After being secreted by the adrenal glands, it circulates in the bloodstream as DHEA-sulfate (DHEAS) and is converted as needed into other hormones. Supplementation with DHEAS has resulted in increased levels of testosterone and androstenedione, two steroid hormones. The FDA banned the sale of DHEA as a therapeutic drug in 1996 until its safety and value could be reviewed. DHEA products on the market as dietary supplements are regulated under a 1994 law, the dietary supplement health and education act (DSHEA,Buy Levitra). Although it is difficult to show clear side effects from DHEA supplements, several publications have raised concerns regarding altered hormone profiles, liver abnormalities, increased cancer risk (prostate in men and breast in women), and other steroid-like effects (increased facial hair, acne, mood swings). Since DHEA is converted into testosterone, there have been concerns that chronic use in men might worsen prostate hyperplasia or even promote prostate cancer.
