Studies have also shown that maca root can help rebalance hormones, decrease total cholesterol and treat constipation. It is even a rare example of a land-based vegetable that is rich in the essential, thyroid-regulating trace mineral, iodine.
However, maca contains another health benefit that is often overlooked by researchers: it is an excellent natural libido and sexual performance booster in both animals and humans, and numerous studies prove it.
Effects on treating sexual dysfunction
Two double-blind studies have confirmed that maca root can treat sexual dysfunction in humans. For the first study, which was published in the Andrologia journal in April 2009, the researchers fed 50 male patients who were suffering from mild erectile dysfunction with either a 2,400 milligram extract of maca rootor a placebo. After 12 weeks of testing, both groups experienced an improvement in their International Index of Erectile Function (IIEF) scores. However, the researchers noted that “patients taking maca experienced a more significant increase than those taking placebo.” The maca group also exhibited greater “sexual well-being” than the control group.
