7 Maca Benefits: Uses, Dosage and What Science Says

Maca benefits may include support for sexual desire, reproductive health, energy, mood, and physical performance. However, some popular claims about this traditional Peruvian root are supported by stronger evidence than others.

Maca is commonly sold as a powder, capsule, or concentrated extract and has gained a reputation as a natural supplement for vitality and hormonal health. But what does scientific research actually say about maca benefits, how much should you take, and is it safe?

Let’s examine its traditional uses, potential effects, dosage, safety, and the current scientific evidence.

Maca is a traditional Peruvian root that has become increasingly popular as a natural supplement for energy, sexual health, fertility, mood, and athletic performance.

Often sold as a powder or concentrated extract, maca has gained a reputation as a natural way to support vitality and hormonal health. But what does scientific research actually say?

Let’s take a closer look at maca, its potential benefits, how it may work, and what you should know before using it.

What Is Maca?

Many proposed maca benefits are associated with the root’s nutritional content and unique plant compounds, including macamides.

Maca (Lepidium meyenii) is a plant native to the high-altitude regions of the Andes in Peru.

The root has traditionally been consumed as a food and used in traditional medicine for centuries.

Today, maca is available in several forms, including:

• Maca powder
• Capsules
• Tablets
• Concentrated extracts

Maca contains carbohydrates, proteins, fiber, minerals, and various plant compounds, including macamides, which have attracted scientific interest.

There are also different varieties of maca, commonly described by their color, including yellow, red, and black maca. Their chemical composition and potential effects may differ.

1. Maca May Support Sexual Desire

A human clinical study indexed by PubMed reported an improvement in sexual desire after several weeks of maca supplementation without significant changes in testosterone. A more recent comprehensive scientific review of maca concluded that maca shows potential in areas such as sexual health and fertility, although additional high-quality clinical research is required.

Of all the potential maca benefits, its possible effect on sexual desire is among the most frequently studied in humans.

One of the most frequently studied potential benefits of maca is its effect on sexual desire.

Several small human studies have reported improvements in sexual desire among people taking maca, particularly after several weeks of supplementation.

Importantly, these effects do not necessarily appear to be caused by an increase in testosterone.

In other words, maca may potentially influence sexual well-being without directly acting as a testosterone booster.

However, the available studies are generally small, and researchers still need larger, better-controlled trials to establish how effective maca really is.

2. Maca and Male Fertility

The potential maca benefits for male fertility remain uncertain because studies have used different products, dosages, and research methods.

Maca has also attracted attention for its potential effects on male reproductive health.

Some studies have investigated whether maca can improve:

• Sperm concentration
• Sperm motility
• Semen quality
• Sexual function

Some research has reported positive results, but findings have not been completely consistent.

A systematic review of clinical trials found that evidence for maca’s effects on semen quality remains limited and inconclusive.

Therefore, maca should not currently be considered a proven treatment for male infertility.

3. Does Maca Increase Testosterone?

Maca is not a proven testosterone booster. For lifestyle and nutritional strategies with stronger supporting evidence, read our guide on how to boost testosterone naturally.

It is important to separate possible maca benefits for libido from claims that maca directly increases testosterone.

This is one of the biggest questions surrounding maca.

Maca is frequently marketed online as a natural testosterone booster, but the scientific evidence does not strongly support this claim.

Several human studies have found that maca may improve sexual desire or aspects of sexual function without significantly increasing testosterone levels.

This distinction is important.

Feeling more energetic or experiencing increased libido does not necessarily mean that testosterone has increased.

If you are concerned about low testosterone, a proper medical evaluation and blood testing are much more reliable than using maca as a diagnostic or hormonal treatment.

4. Maca and Energy

More controlled human research is needed before energy and improved endurance can be considered established maca benefits.

Maca is commonly used as a natural energy supplement.

Some people report feeling more energetic after incorporating maca into their diet, and preliminary research has investigated its potential effects on physical performance and fatigue.

However, there is not yet enough high-quality evidence to conclude that maca reliably increases energy levels in everyone.

Its nutritional composition may contribute to its traditional use as a food, but more research is needed to determine whether concentrated maca extracts have meaningful performance-enhancing effects.

5. May Support Mood and Well-Being

For another traditional supplement studied for stress and well-being, explore our evidence-based guide to ashwagandha benefits.

Researchers have also investigated maca in relation to mood and psychological well-being.

Some preliminary studies suggest that maca may have potential effects on mood, particularly in areas related to stress and well-being.

However, human evidence remains limited.

Maca should therefore not be considered a treatment for depression, anxiety, or other mental health conditions.

6. Maca and Menopause

Maca has also been studied in women experiencing symptoms associated with menopause.

Some small studies have reported improvements in areas such as:

• Mood
• Sexual function
• Psychological well-being
• Certain menopausal symptoms

However, the evidence is still limited and more research is needed before maca can be recommended as an established treatment for menopausal symptoms.

7. Could Maca Help Athletic Performance?

Maca has become popular among athletes and fitness enthusiasts because of its traditional reputation for improving stamina and endurance.

Some preliminary research has investigated maca and exercise performance, including endurance activities.

However, there is currently not enough evidence to consider maca a proven sports-performance supplement.

Training, nutrition, hydration, adequate protein intake, and sleep remain much more important factors for improving athletic performance.

Does Maca Affect Hormones?

Maca is sometimes described as a hormone-balancing supplement.

The reality is more complicated.

Current research suggests that maca may influence certain aspects of sexual and reproductive health without necessarily producing large changes in circulating sex hormones.

This is why claims such as “maca dramatically increases testosterone” should be viewed with caution.

Its potential effects may involve neurological, metabolic, or other biological pathways rather than simply increasing testosterone or estrogen.

How Much Maca Should You Take?

There is no universally established therapeutic dose of maca.

Human studies have used different preparations and amounts, making it difficult to recommend one specific dosage for everyone.

Maca powder is commonly added to:

• Smoothies
• Yogurt
• Oatmeal
• Protein shakes
• Coffee or other drinks

If you are using a concentrated extract, follow the manufacturer’s instructions and avoid assuming that the dose of a powder is equivalent to the dose of an extract.

Is Maca Safe?

Understanding possible side effects is just as important as learning about potential maca benefits.

Maca appears to be generally well tolerated when consumed in amounts commonly used as food or dietary supplements.

Possible side effects may include digestive discomfort, particularly when large amounts are consumed.

However, long-term safety data are limited.

People with specific medical conditions or those taking medications should discuss maca supplementation with a healthcare professional before using it regularly.

What About Maca and Thyroid Health?

Because maca is a cruciferous plant, questions sometimes arise about its potential effects on thyroid function.

There is currently no strong evidence that normal amounts of maca cause thyroid problems in healthy individuals.

However, people with thyroid conditions should avoid assuming that any herbal supplement is automatically safe. If you have a thyroid disorder or take thyroid medication, discuss supplementation with your healthcare professional.

How Long Does Maca Take to Work?

Maca is not generally considered an instant-effect supplement.

Studies examining sexual desire and other outcomes have typically used supplementation over several weeks.

Individual responses can vary significantly.

Some people may notice changes in libido or perceived energy, while others may experience little or no noticeable effect.

Maca vs. Testosterone Boosters

Nutritional status can also influence normal hormonal function. Learn more about the potential role of vitamin D benefits and supplementation.

It’s important to distinguish maca from products marketed specifically as testosterone boosters.

Maca may potentially support libido and sexual well-being, but that does not mean it significantly increases testosterone.

If your goal is to improve testosterone naturally, the fundamentals remain more important:

• Adequate sleep
• Resistance training
• Healthy body composition
• Sufficient calories and protein
• Managing chronic stress
• Correcting nutritional deficiencies

Supplements should generally be considered secondary to these factors.

The Bottom Line

The most promising maca benefits appear to involve sexual desire and well-being, but individual results may vary.

Maca is an interesting traditional plant with promising but still limited scientific evidence.

Research suggests that it may support sexual desire and certain aspects of sexual well-being, while evidence for fertility, energy, mood, menopause symptoms, and athletic performance remains less conclusive.

Perhaps the most important point is that maca should not automatically be considered a testosterone booster. Some of its potential benefits may occur without significant changes in testosterone levels.

As with any supplement, product quality, dosage, individual health, and expectations all matter.

Maca may have potential — but science is still working out exactly how much it can do.
