Have you also heard of the plant with the mysterious name maca, also known as Peruvian ginseng? You may even have it on your shelf at home, as it has gained many fans over the years. It is an interesting plant with a significant proportion of bioactive substances, the effects of which can be felt, for example, in your athletic performance or fertility. What are its other benefits?
In this article you will read about the effect of maca on these areas:
What is maca?
The Peruvian Maca (Lepidium peruvianum or Lepidium meyenii), also called Peruvian ginseng, Brazilian ginseng, Peruvian cress or simply maca, is an exceptional plant that grows primarily in the Peruvian Andes at altitudes of 2,800 to 5,000 metres above sea level. It is thus a hardy plant that is not challenged by hard frosts, snow or low oxygen levels.
Maca has been known and loved for centuries, and is a constant in traditional medicine. Its effects are due to its numerous beneficial substances, thanks to which it is now even classified as a superfood. Its nutrients and benefits were recognised by the indigenous inhabitants of the high mountain regions of the Peruvian Andes some 2000 years ago. 
Interestingly, this plant belongs to the brassica family of vegetables, which also includes for example broccoli, cauliflower and cabbage. There is not just one type of maca, but several varieties. You may come across red, yellow, purple or black maca. However, the most widespread and most widely used worldwide is yellow, and in any case, the root is the most used. Each species differs slightly in its content of biologically active substances and so may also have slightly different effects. 
What are the health benefits of maca?
1. It has antioxidant properties
Maca contains a mixture of various bioactive compounds, many of which act as antioxidants. For example, phenolics, alkamides or glucosinolates.
Thanks to the effects of these substances, maca helps to fight free radicals, which are produced by oxidative stress. This can occur, for example, as a result of smoking or excessive exposure to UV radiation, which can further lead to premature skin ageing.
Some studies have even shown that certain substances contained in maca (e.g. macamides) have an effect on tumour cells and may limit their growth.
In addition, thanks to its antioxidant properties, maca may be useful, for example, in athletic sports where muscle damage occurs. In fact, it can help to better manage muscle fatigue. [1,12]
Antioxidants generally play an important role in the prevention of chronic diseases that are related to oxidative stress and inflammation in the body. Thus, maca can be a useful part of an overall healthy lifestyle that can help you stay physically fit, healthy and stay in shape. 
2. Positive effect on brain and cognitive abilities
One of the most well-known effects of maca is its positive effect on the brain. Not only is it involved in the protection of nerve cells, but it may even be useful for the memory or other cognitive functions. These include, for example, the ability to learn, concentrate or maintain attention.
How does maca affect the brain?
- Studies show its effect on improving cognitive functions such as memory or learning. [7,12]
- Its antioxidant effects also seem to be involved in the protection of neurons (nerve cells). 
- For example, macamides could have a protective effect on nerve cells. These help to promote the processes that lead to nerve cell growth. 
- In addition, it turns out that maca could alleviate brain damage caused by beta-amyloid plaques (clumps of proteins). These typically accumulate in the brain in Alzheimer’s disease. 
- Studies are also showing a possible effect in other neurodegenerative diseases (Parkinson’s disease, Huntington’s disease). 
If you want to support brain health and improve your memory, concentration or other cognitive functions, maca could be an option for you. Its properties make it ideal when you’re working or studying hard or dealing with complex tasks. It can also help with brain health as well, as part of a healthy ageing and anti-ageing approach.

3. Can improve sports performance
Studies also report positive effects of maca on athletic performance, especially in terms of endurance activities and muscle recovery.
How does maca affect sporting performance?
- The use of maca is said to have an energising effect. This could potentially result in better endurance performance.
- In some studies, an effect on hormonal balance has also been observed, specifically on sex hormone levels ( oestrogen, testosterone, etc.). Maintaining optimal levels is essential for the body, as an upward or downward deviation can manifest itself in various problems. 
- The antioxidant properties of maca could help with muscle recovery, which may reduce muscle damage after exercise, for example.
- Maca is also known to have promising effects on relieving fatigue.

A scientific perspective on maca: What effect does it have on cycling performance?
In the study, researchers followed a group of eight cyclists. Half of them took 2g of maca per day for two weeks, while the other half consumed a placebo in the form of Arabic gum. The groups were then swapped and those taking the placebo were given maca and vice versa.
The aim was to find out if maca had an effect on their cycling performance. Therefore, they completed a 40 km race before the start of each stage and repeated it after the end of each stage. It turned out that their race time was better after taking maca than without it. Performance improved by a full minute on average. While this may seem like a negligible amount at first glance, in reality, every second counts in endurance races. 
From research available, it seems that maca could be useful if you are involved in endurance as well as strength sports. This could include not only cycling, but also running, strength training or intense activities such as crossfit. Maca may be involved in the processes related to athletic performance, recovery or fatigue management.

4. Can enhance libido and sexual health
Maca has been used in the past to support fertility or libido. It is now also being shown in research that it could actually have a positive effect on these areas of one’s sex life.
The impact of maca on sexual health and desire for sex
- The effect on libido is often apparent in both men and women, and often, for example, in menopausal women. 
- It is also likely to have an effect on hormonal balance, which is also related to better sexual function.
- It also might possibly help with erectile dysfunction. [4,15]
- Actions to relieve stress can also translate into a higher desire for sex and intimacy.

A scientific perspective on maca: What effect does it have on libido?
One study followed a group of 57 healthy men over 12 weeks. They were divided into three groups, with one group taking 1.5 g of maca daily, the second taking 3 g, and the third receiving a placebo. The researchers tracked the effect of maca on libido – participants rated it by giving a score (e.g., a value of 1 = no change, a value of 3 = slight increase, etc.). The study found that after twelve weeks of follow-up, men taking maca (at both doses) experienced an approximate 40% increase in libido. 
In the event that you want to boost your sexual health and increase your desire for sex, maca could be the aphrodisiac worth trying.
5. Effect on women’s health
Maca is a plant that is appreciated by many women as it proves to be helpful in terms of menopause, the menstrual cycle and overall hormonal balance.
How can maca improve women’s health?
- It could relieve some of the symptoms of menopause, such as hot flushes or night sweats. 
- Its effect is also seen in menopause-related psychological problems, such as depressive states or anxiety. 
- It also appears that it can help to optimise hormonal balance during menopause. [5,15]
- Available studies suggest that it could also help with increasing oestrogen levels. 
From resources available so far, it seems that maca may also be suitable if you need help with menopausal symptoms. Thus, it may be the supplement that could make this period a little more bearable for you.

6. It has an effect on male health and fertility
The use of maca is popular and widespread among men, as it is known for its benefits on fertility and testosterone.
How can maca improve men’s health?
- Studies suggest that it has a positive effect on sperm quantity and quality (morphology). 
- It is also apparently involved in improving sperm mobility (motility). Greater sperm motility means better sperm activity and a greater likelihood of fertilising the egg.
- Maca is associated with optimal hormonal balance not only in women, but also in men.
- Apparently, it can also help with achieving optimal testosterone levels. 
- It has also been shown to have a positive effect on prostate health.
As you can see, it turns out that maca can be beneficial for men’s health as well. Not only is it useful in helping to care for the prostate, but also for optimal testosterone levels. The latter is an important male hormone that affects both the muscles and the overall vitality of the male body. Along with its effect on the quantity, quality and motility of sperm, maca is thus an interesting plant that could come in handy in promoting fertility.
Our article Men and Nutrition: The Most Important Vitamins and Minerals for Health, Testosterone and Performance will explain more about the substances that men’s health will appreciate.
A scientific perspective on maca: What effect does it have on sperm quality?
A group of researchers looked at the effect of maca use on sperm quality in eighteen healthy men in a study. Eleven of them took 1.75 g of maca for twelve weeks, while the remaining seven were given a placebo. The aim was to see if maca had an effect on sperm quality and count. It turned out that taking maca increased sperm concentration, or the number of motile sperm, by an average of 14%. 
7. Can improve mental health
The effect of maca on nerve cells and the brain can also be reflected in mental health. This plant is known for its promising effect on improving mood and overall psychological well-being. Studies also show that the amount of energy felt after taking it can increase. It could even have a positive effect on sleep and even help to cope better with stress. [3,16,19]
In scientific papers, its contribution to the alleviation of anxiety or depressive states, for example, is also discussed. Thus, according to the results of these studies, maca appears to have antidepressant and anxiolytic effects. [10,13,19]
Therefore, if you’re looking for a herbal supplement to help you cope with daily mental strain and stress, maca may be a worthy candidate. You would do well to combine it with a healthy lifestyle, other stress management techniques or a range of other adaptogens such as the popular ashwagandha.
Other possible health benefits
- It could also play a role in the prevention of osteoporosis during menopause, which is linked to low oestrogen levels, and which studies suggest maca could help optimise. 
- It is also demonstrating its potential effect on type 2 diabetes. In fact, in studies, an effect on increased insulin secretion has been observed. 
- It seems that maca could also have an effect on improving blood pressure levels.
