HelloPharmacist Scorecard of Maca 500 mg by NOW
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: maca root, 500 mg per capsule. Maca is a plant used in traditional medicine and foods.
The capsule itself is made from hypromellose (a plant-based capsule material) and stearic acid (a binder).
Does it work?
Insufficient evidence
The evidence we hold doesn't establish that maca is effective for any of the conditions it's marketed for—including amenorrhea (missed periods), chronic anemia, depression-related sexual dysfunction, athletic performance, or osteoporosis. All of those carry a rating of insufficient reliable evidence.
That doesn't mean it doesn't work; it means the research to prove it isn't solid enough yet.
How safe is it?
Well-documented data
Maca is generally well tolerated when eaten as a food, but long-term safety in supplement amounts hasn't been studied. Fresh, uncooked maca can cause stomach pain in some people.
The safety data advises against using it during pregnancy and breastfeeding because there isn't enough reliable information to know it's safe in those situations.
Meds to double-check
No known interactions
No interactions are documented in our data for maca.
The bottom line
Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Maca might appeal to you if you're exploring traditional remedies, but the evidence for what it actually does isn't established in our data. If you're pregnant, breastfeeding, or have concerns about long-term supplement use, talk with your pharmacist or doctor before starting.
Since it's not documented to interact with medications, it's worth checking your specific drugs anyway—just to be sure.

Formula
Maca (Lepidium meyenii) is grown at high elevations in the Andes region of Central Peru. It has been traditionally used for centuries as a food source and as a general energy tonic. Modern scientific research suggests that maca may help to support a healthy reproductive life for both men and women. Clinical data indicate that maca does not exert a direct effect on endocrine function.
