Do Maca Supplements Really Help Boost Energy?

Dr. Oz has the answer.

The Claim: Fans say that maca root powder in smoothies, capsules, or foods can boost energy, mood, and sex drive and take down blood pressure and menopause symptoms.

Maca comes in red, yellow, and black varieties, each with different levels of about a dozen active compounds, says Debra M.

So basically: It's a gamble.

The Verdict: Skip It
