What is Maca Root?
Maca (Lepidium meyenii) is a cruciferous vegetable native to the high-altitude Andes Mountains of Peru, where it has been cultivated for over 2,000 years. Growing at elevations between 4,000–4,500 meters (13,000–15,000 feet), maca thrives in harsh conditions where few other plants survive—and this extreme environment contributes to its unique phytochemical profile.
Traditionally used by indigenous Peruvians as both a staple food and medicine, maca earned the nickname “Peruvian ginseng” for its adaptogenic properties. Unlike stimulants that provide a temporary boost, adaptogens help your body maintain balance and resist stress over time.
Key bioactive compounds in maca include:
- Macamides and macaenes – Unique fatty acid compounds found only in maca, responsible for many of its effects on energy, mood, and libido
- Glucosinolates – Sulfur-containing compounds with antioxidant and potential anti-cancer properties
- Polysaccharides – Complex carbohydrates that support immune function
- Amino acids – including all essential amino acids for protein synthesis
- Vitamins and minerals – Rich in vitamin C, copper, iron, potassium, and B vitamins
A 2024 comprehensive review published in Frontiers in Pharmacology confirmed that maca demonstrates neuroprotective, anti-inflammatory, immunoregulatory, and antioxidant effects in both preclinical and clinical studies (PMC10910417).
Science-Backed Benefits of Maca Supplements
What does the research actually say? Here are the benefits supported by clinical evidence:
1. Energy & Stamina Enhancement
One of maca’s most consistent effects is its ability to increase energy without the jitters or crashes associated with caffeine. Multiple studies show improved physical performance, reduced fatigue, and enhanced endurance in both athletes and general populations.
A study on elite athletes found that 8 weeks of black maca supplementation improved cycling time performance compared to baseline (PMC3184420). Another study showed cyclists improved their 40km time trial performance after just 14 days of supplementation.

2. Sexual Desire & Function
Perhaps maca’s most famous benefit, multiple randomized controlled trials confirm its positive effects on libido in both men and women—often without directly changing hormone levels.
A 12-week study of 57 healthy men found a 40-42% improvement in self-perceived sexual desire by weeks 8-12 (PMC3184420). Importantly, this occurred without measurable changes in testosterone, suggesting maca works through different mechanisms than hormone replacement.
For women, research shows maca effectively addresses antidepressant-induced sexual dysfunction. A dose-finding study found that 3g/day significantly improved sexual function scores, while 1.5g/day did not produce the same effects (PMC6494062).
3. Hormone Balance (Without Adding Hormones)
Here’s what makes maca unique among supplements claiming to support hormones: it doesn’t contain plant estrogens or phytohormones. Instead, maca works through the hypothalamic-pituitary axis, essentially helping your body optimize its own hormone production.
Research confirms maca contains no plant hormones but instead uses plant sterols to stimulate the endocrine system and maintain hormonal balance (PMC3614596). This makes it a fundamentally different approach than phytoestrogen-based supplements like black cohosh.

4. Menopausal Symptom Relief
Multiple clinical trials demonstrate maca’s effectiveness for perimenopause and menopause symptoms—including hot flashes, mood changes, and sleep disturbances.
A pilot study in perimenopausal women showed gelatinized maca acted as a non-hormonal alternative to HRT, improving symptoms while also demonstrating energizing effects (PMC3614596).
5. Male Fertility & Sperm Health
Black maca specifically shows the strongest evidence for improving male reproductive parameters. Research demonstrates improvements in sperm concentration, motility, and overall semen quality.
One study found black maca affected sperm production in as little as one day of treatment, with continued improvements over time (PMC3184420).

6. Mood & Mental Wellbeing
Maca demonstrates mood-balancing effects, particularly for reducing anxiety and depression symptoms. Studies in postmenopausal women show reduced depression scores and improved psychological symptoms.
Research suggests these effects occur through maca’s influence on the endocannabinoid system—macamides act as fatty acid amide hydrolase (FAAH) inhibitors, which help regulate mood and stress response.

7. Cognitive Function & Memory
Black maca specifically shows neuroprotective effects, with studies demonstrating improved learning and memory in animal models. This may be related to maca’s antioxidant properties, protecting brain cells from oxidative stress.

Maca Types: Black vs Red vs Yellow
Not all maca is created equal. The color of the maca root determines its phytochemical profile and, consequently, which benefits it delivers best.
Yellow Maca (60-70% of harvest)
Yellow maca is the most common variety and serves as an excellent all-purpose option. It’s the most studied form and provides balanced benefits across energy, mood, and general wellness.
Best for: General wellness, daily energy support, newcomers to maca
Red Maca (20-25% of harvest)
Red maca contains higher levels of anthocyanins (antioxidants) and shows particular strength in female-specific benefits.
Best for: Women’s hormone balance, bone health support, prostate health in men
Scientific backing: Studies show red maca specifically reduces prostate size in rats and supports bone density better than other varieties.
Black Maca (10-15% of harvest)
The rarest variety, black maca, consistently outperforms other colors in studies on male fertility, cognitive function, and athletic performance. It contains higher concentrations of macamides and fatty acids.
Best for: Male fertility, memory and cognition, athletic performance, energy
Scientific backing: A clinical trial with 175 participants found black maca significantly improved sperm concentration compared to red or yellow varieties (PMC5039502).

Quick Comparison Table
Variety | % of Harvest | Primary Benefits | Best For |
Yellow | 60-70% | General energy, mood, hormone balance | Everyone / Daily use |
Red | 20-25% | Bone health, female hormones, prostate | Women / Men 40+ |
Black | 10-15% | Fertility, cognition, athletic performance | Men / Athletes |
Forms of Maca Supplements
Choosing the right form affects absorption, convenience, and results.
Raw Maca Powder
Ground from sun-dried roots without heating above 105°F. Retains maximum enzymes but contains difficult-to-digest starches that can cause digestive discomfort.
Pros: Maximum enzyme content, versatile for recipes, and most affordable. Cons: Can cause bloating/gas, contains raw starches, earthy taste
Gelatinized Maca Powder
Despite the name, this contains no gelatin. The gelatinization process uses heat and pressure to remove starch, resulting in a product that’s 4x more concentrated in minerals and dramatically easier to digest.
Pros: 4x mineral concentration, excellent digestibility, better taste.e Cons: Some enzyme loss, slightly more expensive
Maca Capsules
Pre-measured doses of powder (raw or gelatinized) in vegetable or gelatin shells.
Pros: Convenient, precise dosing, no taste, portable. Cons: Slower absorption, cannot add to recipes
Maca Extract
Concentrated liquid or powder extracts (4:1, 6:1, 10:1 ratios) provide maximum potency in minimal doses.
Pros: Highest potency, fast absorption. Cons: Most expensive, may lack synergistic compounds

How to Choose the Right Maca Health Supplement
With thousands of maca food supplements available, here’s what separates quality products from the rest:
Non-Negotiable Quality Markers
Peruvian Origin
Authentic maca must come from the high-altitude Andes of Peru—specifically regions like Junín at 4,000+ meters elevation. Maca grown in China or at lower altitudes contains significantly fewer bioactive compounds due to different soil composition and climate conditions.
Gelatinized Form
Unless you have a strong digestive system and want to add maca to recipes, gelatinized maca offers superior absorption, 4x mineral concentration, and dramatically fewer digestive side effects.
Third-Party Testing
Look for products tested by independent laboratories for purity, potency, and contaminants. Heavy metal testing is particularly important for root vegetables grown in mineral-rich soils.
GMP Certification
Good Manufacturing Practices certification ensures the product was made in a facility meeting strict quality and safety standards.
Red Flags to Avoid
- No country of origin listed
- Unusually low prices often indicate Chinese-grown maca.
- No third-party testing mentioned
- Contains fillers, artificial colors, or unnecessary additives
- No specific maca color/variety identified
Why Multi-Ingredient Formulas Outperform Standalone Maca
Here’s what most maca vitamin products don’t address: maca works best when supported by complementary ingredients.
The problem with standalone maca:
Maca supports your endocrine system—but it doesn’t directly address cortisol (the stress hormone that undermines hormone balance), inflammation (which impairs nutrient absorption), or absorption itself. Taking maca alone means you’re only addressing part of the equation.
Circle of Nature Maca Root + Ashwagandha combines four synergistic ingredients:10,000 mg maca root raw form, which is equivalent to 500 mg of extract.
Organic Maca Root delivers the adaptogenic foundation—supporting energy, hormone balance, and vitality through the mechanisms described throughout this guide.
Ashwagandha directly reduces cortisol levels, protecting your endocrine system from stress damage. Research shows ashwagandha increases testosterone in men (PMC8166567)—something maca alone doesn’t reliably do.
Turmeric Curcumin (95% curcuminoids) combats inflammation that impairs nutrient absorption and hormone function, particularly important as we age.
BioPerine® Black Pepper Extract enhances absorption of all ingredients by up to 2,000%, ensuring you actually utilize what you’re taking.
This combination addresses the complete picture: adaptogenic support, stress protection, anti-inflammatory action, and enhanced absorption—all in a single, convenient capsule.
Made in a GMP-certified USA facility with no fillers, no artificial ingredients, and no unnecessary additives.
Frequently Asked Questions
Q: What does maca root supplement do?
A maca root supplement supports energy levels, hormone balance, libido, and overall vitality through adaptogenic mechanisms. Rather than adding hormones to your body, maca helps optimize your own endocrine system function. Benefits typically develop over 2-12 weeks of consistent use.
Q: Can I take maca every day?
Yes. Clinical studies lasting up to 12 weeks with daily dosing show maca is safe for regular use. Some practitioners recommend cycling (5 days on, 2 days off), though continuous daily use is also well-tolerated.
Q: How long does it take for maca to work?
Energy improvements may appear within 1-2 weeks. Libido benefits typically emerge around weeks 4-8. Hormonal balance and fertility improvements often require 8-12 weeks of consistent use.
Q: Is maca root the same as a multivitamin?
No. While maca contains vitamins and minerals, maca root vitamins provide unique bioactive compounds (macamides, macaenes, glucosinolates) not found in standard multivitamins. Maca works as an adaptogen, while multivitamins simply provide essential nutrients.
