What Are the Benefits of Maca Root?
Maca root (Lepidium meyenii) is a nutrient-dense plant native to the high Andes of Peru, often called "Peruvian ginseng." For centuries, it's been used as a natural way to support energy, stamina, mood balance, and overall vitality. Today, maca is one of the most researched adaptogens in the functional nutrition world, backed by human clinical studies showing measurable benefits when taken as part of a healthy lifestyle.
Below, we'll explore what makes maca unique—especially gelatinized black maca, how it works, and what to look for in a high-quality supplement.
What Is Maca Root?
Maca is a cruciferous vegetable, related to broccoli and kale, that grows in harsh, high-altitude conditions of the Peruvian Andes. The root is the edible portion, rich in bioactive compounds such as macaenes, macamides, and glucosinolates—thought to be responsible for its energizing and balancing effects.
Traditionally, maca was consumed as a cooked root or flour. Modern supplements are typically powders, capsules, or extracts standardized for these unique compounds. Because maca is naturally caffeine-free, it's a popular option for people seeking a steady lift in energy without jitters.
The Difference Between Raw and Gelatinized Maca
Raw maca powder is simply ground dried root, but it can be hard to digest and may contain resistant starches.
Gelatinized maca is not related to animal gelatin—it's a plant-based process that uses heat and pressure to remove starch, making it more digestible and concentrated.
Studies show that gelatinization increases the bioavailability of active compounds and reduces digestive discomfort compared to raw forms (Gonzales et al., 2014). For most people, gelatinized black maca offers superior absorption and a smoother flavor profile, especially in supplements.
Science-Backed Benefits of Maca Root
The benefits of maca are broad and supported by multiple human trials. Here's what the science shows.
1. Supports Energy and Stamina*
Several studies show maca can help promote physical endurance and reduce fatigue without acting as a stimulant.
In a double-blind, placebo-controlled trial, healthy male cyclists who supplemented with maca extract for 14 days showed measurable improvements in time trial performance and self-perceived energy compared to placebo (Stone et al., 2009). These findings support maca's traditional use for sustained energy and stamina.
2. Promotes Balanced Mood and Stress Response*
Maca is considered an adaptogen, meaning it helps the body adapt to physical and emotional stress.
A 2015 randomized, double-blind study in postmenopausal women found that 3.3 grams of maca daily for six weeks supported a balanced mood and sense of well-being compared with placebo (Brooks et al., 2008). Researchers attributed this to maca's potential influence on neurotransmitters like serotonin and dopamine.
3. Supports Hormonal Balance and Reproductive Health (Within Normal Ranges)*
Maca has been shown to support hormonal equilibrium in both men and women—without acting like an external hormone or containing phytoestrogens.
In men, maca has been associated with supporting normal reproductive parameters, such as sperm quality and motility, in several studies (Gonzales et al., 2001; Gonzales et al., 2002).
In women, pilot trials suggest maca may help maintain normal menstrual function and well-being during menopause (Meissner et al., 2006).
These studies suggest maca nourishes the hypothalamic–pituitary–adrenal (HPA) axis, which regulates hormonal balance and stress response—key for overall vitality.
4. Antioxidant and Nutrient Support*
Maca contains naturally occurring polyphenols and flavonoids that help protect cells from oxidative stress.
A study published in Food Chemistry found that maca extracts demonstrated significant antioxidant capacity due to their high content of polyphenols and glucosinolates, supporting the body’s natural defense against oxidative stress (Lee et al., 2011).
Antioxidants in maca—particularly in black and red varieties—may play a role in maintaining overall cellular health, energy metabolism, and recovery.
What Makes Black Maca Unique?
Not all maca is the same. The color of the root—yellow, red, or black—reflects different phytonutrient profiles.
- Yellow maca: most common; general vitality and balance.
- Red maca: studied for prostate and bone-supporting properties.
- Black maca: known for supporting stamina, mood, and cognitive performance.
A comparative study found that black maca showed the most pronounced effects on energy, learning, and sperm parameters, while red maca had different benefits (Gonzales et al., 2007). This makes black maca the preferred choice for people seeking physical and mental performance support.
What to Look for in a Maca Supplement
Because maca has become so popular, quality varies widely. Here's how to choose a supplement that actually delivers the studied benefits:
Origin Matters – Choose Peruvian Maca
Authentic maca comes from the Andean highlands of Peru. The soil and altitude affect its phytochemical profile. Always look for the label "Grown in Peru."
Organic Certification
Maca should be USDA Certified Organic to ensure it's free from synthetic pesticides and fertilizers. Organic standards also preserve the traditional cultivation methods used by local Peruvian farmers.
Gelatinized Form
Choose gelatinized maca—not raw—for easier digestion, better absorption, and greater bioactive concentration. Gelatinization is a heat-pressure process that enhances nutrient availability.
Third-Party Tested
Look for supplements that are third-party tested for purity, heavy metals, and potency. This ensures product safety and quality, especially when buying online.
Black Maca for Peak Support
If your goal is energy, focus, and balance, black maca—particularly in gelatinized form—is often the best-researched option.
How to Use Maca Root Safely
Most studies use 1.5–3 grams per day (roughly 1–2 teaspoons of powder or 2–3 capsules) over several weeks. It's best taken with food or blended into smoothies, coffee, or oats.
Because maca supports hormonal balance naturally, consistency matters more than high doses. Always consult your healthcare provider if you are pregnant, nursing, or taking medications before starting any supplement.
Key Takeaways
- Maca root is an adaptogenic plant from Peru that supports energy, stamina, mood, and balance.
- Gelatinized black maca is easier to digest and may offer the most pronounced benefits for vitality and focus.
- Look for organic, Peruvian-grown, and third-party tested supplements for quality assurance.
