The maca plant is native to central Peru and can be found growing at very high altitudes. It’s often sold as a powder, in capsules, or as a liquid extract.
Its history dates back to the Incan Empire, and it’s widely used in Peruvian cuisine and medicine. Maca shows promise as a male health supplement.
Its health claims include improved sexual performance, libido, fertility, energy, and stamina. However, research into the effectiveness of maca is still in its infancy, and still ongoing. Many of the published studies have relied upon small sample sizes or animal models, and have been unable to draw firm conclusions.
Thanks to social media and celebrity endorsements, the maca plant has come from relative obscurity to superfood superstardom.
The plant’s root is available in a range of forms and colours (most notably red, yellow, and black), and has been traditionally used to boost libido, enhance fertility, and improve stamina.
But how do those claims stack up? In this article, we’re going to explain what maca is and how to use it, before delving into its potential health benefits and side effects.
What Is Maca?
Maca (Lepidium meyenii) — otherwise known as Peruvian ginseng — is an edible herbaceous plant of the Brassicaceae or Cruciferae family. This makes it a cruciferous vegetable, and a relation of broccoli, cabbage, cauliflower, and kale.
Native to South America, maca can be found flourishing in the harsh climates and lofty altitudes of the Andes in central Peru, some 12,500 feet (3,800 metres) above sea level.
The turnip-like root, which grows underground, is the main edible part of the plant. And long before it arrived on the superfood supplement scene, it was widely used in Peruvian cuisine and medicine for centuries.
How to Use Maca
Incorporating maca into your diet is simple. The root is typically dried and sold as a powder, although it can also be purchased in capsules or as a liquid extract.
It can be taken as a supplement, but some people like to mask the taste by mixing it in with their favourite baked goods, porridge, oatmeal, energy drinks, or smoothies. Maca has a distinct flavour — described as mildly nutty and earthy, with a hint of butterscotch.
You’ll find maca for sale in most major supermarkets, in specialist health food shops, and from online retailers.

Potential Health Benefits of Maca
There are a number of potential health benefits to using maca supplements. Yet, before we examine these claims in a little more detail, it’s important to note that research into the efficacy of maca is still in its infancy, and still ongoing.
Many of the studies use small sample sizes, while some have been animal studies and others have been sponsored by companies with a vested interest in producing or selling maca.
One benefit, however, is beyond question. As a food supplement, maca is high in nutritional value and full of vitamins & minerals.
Other maca male health benefits may include:
- Increased fertility
- Improved libido and sexual performance
- Increased energy and improved athletic performance
- Reduced prostate size
Maca Is Highly Nutritious and Full of Vitamins & Minerals
While some of the claims further down this article are worthy of scrutiny, there’s no getting away from the fact that maca root is highly nutritious. It’s a good source of carbs, it’s low in saturated fat and sodium, and it contains a healthy amount of fibre.
Maca is also rich in amino acids and a great source of essential vitamins and minerals, including vitamin B6, vitamin C, copper, manganese, and iron. But a considerable part of its calorific profile comes from sugars (32.1g per 100g serving), so it should be used sparingly; especially by diabetics.
Maca May Increase Fertility
Sperm quality AND quantity are vital to male fertility. And maca remains a popular choice among men looking for a natural way to improve both the quality and the quantity of their sperm.
A 2016 review of clinical trials by Korean researchers suggested that maca favourably affects sperm mobility and semen quality in both fertile and infertile men.
However, the total number of trials, the small sample size, and the risk of bias of the included studies prevented the research team from drawing any firm conclusions.
Maca May Improve Libido and Sexual Performance
A reduction in sexual desire is a common issue — and it’s one that a number of natural supplements readily claim to solve. Maca is no different, although its claim is at least backed by some research:
- A 2002 double-blind placebo-controlled study observed an improvement in sexual desire after 8 weeks of ingesting maca;
- And a 2010 review of randomized clinical trials found that maca improved sexual desire after 6 weeks.
The 2010 study does, however, highlight that the total sample size was too limited to draw firm conclusions and that more rigorous studies are required.
There are also suggestions that black maca can alleviate stress, a common contributor to erectile dysfunction (ED). Yet, beyond a small 2009 study, there’s minimal evidence that maca can directly affect or improve erectile function.

Maca May Increase Energy and Improve Athletic Performance
It’s claimed that maca helps to increase strength and endurance, boost energy, and gain muscle mass. These claims have made maca root powder a popular supplement among the bodybuilding community, and with athletes in general.
But what does the science say?
A small study of eight male cyclists set them the task of completing a 40km time trial, before spending 14 days supplementing with maca extract. After the two weeks were up, they cycled the same route, completing the ride in a quicker time.
Meanwhile, a number of animals studies involving mice and rats point to maca enhancing endurance performance.
However, there remains no evidence to suggest that maca increases strength or muscle mass.
Maca May Reduce Prostate Size
An enlarged prostate gland — a common issue faced by men as they age — can cause problems with the passing of urine. This, in turn, can result in painful urination, painful ejaculations, and general abdominal discomfort.
Does maca offer a natural remedy?
While a 2007 animal study suggests that red maca could potentially reduce the size of the prostate, this has yet to be proven by a corresponding human study.
What Are the Side Effects of Maca?
Maca is generally safe for consumption and unlikely to cause any serious side effects in moderate doses.
But if you suffer from thyroid problems, you should think twice about adding maca to your daily routine. It contains goitrogens, substances that can interfere with the normal functioning of the thyroid gland.
In Summary
As a food supplement, there’s no denying the nutritional benefits of adding maca to your diet.
However, while it shows promise as a natural male health supplement, studies remain thin on the ground. Those that do exist have relied upon small sample sizes or animal models, and only large-scale human studies will determine if maca is as effective as its marketing suggests.
And while there is some evidence to suggest it can help with ED and libido, this has not yet been proven conclusively. Maca cannot, therefore, be compared with FDA-approved drugs like Sildenafil and Tadalafil.
