Maca has a reputation as nature's answer to flagging desire, and for once the folklore has some data behind it. This guide walks through what maca is, the small but real studies on libido and mood, how red and yellow varieties differ, and how to fold it into your routine without wasting money or hope on marketing hype.
What Maca Actually Is
Maca (Lepidium meyenii) is a cruciferous root vegetable grown high in the Peruvian Andes, related to radishes and broccoli. For centuries Andean communities have eaten it as a staple food and used it to support fertility and stamina. Unlike many trendy adaptogens, maca has a genuine culinary history, which is part of why it has a reasonable safety record at food-level amounts.
Maca does not contain hormones and does not appear to raise estrogen or testosterone directly. Instead, researchers think its unique compounds, including macamides and macaenes, may act on mood, energy, and sexual function through pathways that are still being mapped. That distinction matters: maca is not a substitute for hormone therapy, and it will not fix a problem rooted in an untreated deficiency.
What the Research Says About Libido
Several small randomized trials have looked at maca and sexual desire. A frequently cited 12-week study in men found improved self-reported desire independent of changes in testosterone or mood, and a handful of studies in women point in a similar direction, especially for two specific situations.
The most promising women's data involves antidepressant-related low libido. In small trials, maca modestly improved sexual function in women taking SSRIs, a group who often struggle with medication-related dampening of desire. There is also early evidence that maca may ease certain menopausal symptoms and improve wellbeing, though sample sizes are small and results are mixed.
- Effects are usually modest and build over weeks, not overnight
- The strongest signal is in SSRI-related low libido and around menopause
- Maca is not proven to work by changing sex hormone levels
- Larger, longer studies are still needed before firm claims are fair
A Note on SSRI-Related Low Desire
If your libido dropped after starting an antidepressant, that is common and it is not a personal failing. Maca is one gentle option some women try, but never stop or change a prescribed medication on your own. A clinician can discuss dose timing, switching agents, or add-on strategies that are better studied than any supplement.
| Color | Often Chosen For |
|---|---|
| Yellow | The most common, all-purpose everyday root, mildest flavor |
| Red | Popular with women for mood, bone, and hormonal-balance support |
| Black | Traditionally linked to energy, stamina, and focus |
Gelatinized vs. Raw Powder
Gelatinized maca has been gently heated to remove starch, which many people find easier to digest than raw powder. If maca gives you bloating or gas, switching to gelatinized often helps. Raw powder retains a stronger flavor and is fine for those who tolerate it well.
Shop Quality Maca Powder and Capsules
Look for organic Peruvian maca with clear sourcing and third-party testing. iHerb stocks red, yellow, and gelatinized options in both powder and capsule form so you can match the variety to your goals.

Most studies use somewhere between 1.5 and 3 grams of maca per day, often split into smaller amounts. A sensible approach is to start low, around a teaspoon of powder or a standard capsule dose, and increase gradually over a couple of weeks while you watch how you feel.
Powder blends easily into smoothies, oatmeal, or coffee and has a nutty, slightly malty taste. Capsules are convenient if you dislike the flavor. Because any libido or energy benefit tends to build over three to twelve weeks, give it an honest trial before deciding whether it works for you.
- Take it earlier in the day if it feels energizing
- Consistency matters more than a single large dose
- Pair powder with fat or protein to smooth the flavor

Maca is generally well tolerated at food-level amounts, and side effects are usually mild, such as digestive upset or feeling wired if taken late in the day. Still, supplements are not risk-free for everyone.
Because maca has not been studied enough in pregnancy or breastfeeding, it is best avoided during those times unless your clinician approves. If you have a hormone-sensitive condition, thyroid disease, or take any medication, check with a professional first. And remember that persistent low libido can signal something treatable underneath, such as iron or vitamin D deficiency, thyroid issues, or the side effects of a medication, all worth investigating.
- Avoid in pregnancy and breastfeeding unless cleared by a clinician
- Discuss with your provider if you have thyroid or hormone-sensitive conditions
- Low desire that persists deserves a proper medical workup, not just a supplement
