Maca showed promising effects on menopausal symptoms including hot flashes and mood
Sexual dysfunction improved in menopausal women across available trials
Evidence limited by small sample sizes and methodological concerns in existing RCTs
3Erectile and sexual function in men with EDMeta-Analyse2025
Einfach gesagt: In contrast, evidence for other agents such as Tribulus terrestris and Maca remains insufficient, underscoring the need for larger, high-quality trials with longer follow-up.
Ho CY et al. · Journal of traditional and complementary medicine (2025)
Fourteen RCTs with a total of 1227 males with ED were included.
Herbal dietary supplements as a class had significant positive effects on erectile function (SMD = 1.20), sexual desire (SMD = 1.02), and satisfaction, driven mainly by saffron and ginseng.
In contrast, evidence for other agents such as Tribulus terrestris and Maca remains insufficient, underscoring the need for larger, high-quality trials with longer follow-up.
4Metabolic syndrome parametersSystematische Übersichtn=113 · medium study2018
Einfach gesagt: Furthermore, conclusions may be different if other health benefits are considered.
van den Driessche JJ et al. · Food & function (2018)
Overall, only limited evidence was found for the effects of the foods described as superfoods on metabolic syndrome parameters, since results were not consistent or the number of controlled intervention trials was limited.
The inconsistencies might have been related to intervention-related factors, such as duration or dose.
Furthermore, conclusions may be different if other health benefits are considered.
Einfach gesagt: Nevertheless, due to individual differences and limitations of the subjects, further high-quality studies are needed to confirm the clinical efficacy of the plant.
Chen R et al. · Phytotherapy research : PTR (2021)
Additionally, the research on the change of active components in Maca at different growth stages by MS will be beneficial to full utilization of active components in Maca and other natural resources.
We reviewed the study in the visible distribution of amino acids, amide alkaloids, imidazolium alkaloids, and saccharides in Maca by imaging mass spectrometry (IMS).
We also reviewed the pharmacology value associated with improvement of reproductive function, anti-stress response, anti-osteoporosis, antitumor activity, clinical research and toxicity of Maca, and so forth.

Wang S et al. · Food chemistry (2019)
Plant genetics, botanical parts, processing, extraction, and experimental protocols represent the major factors affecting the chemical composition, physicochemical attributes, and health effects of maca-based products.
However, clinical studies to support the claimed health effects of maca and related mechanisms appear to be lacking.
Product innovation and diversification in food and non-food utilization of different parts of maca to maximize the value perceptions are suggested.
Einfach gesagt: This review documents the Peruvian maca composition and the recent findings regarding the medicinal effects of this root in sexual dysfunction regulation, neuroprotective effects, action in memory enhancement, antidepressant, antioxidant, anti-cancer, and anti-inflammatory activities, and skin protection.
da Silva Leitão Peres N et al. · Food & function (2020)
Peruvian maca (Lepidium meyenii) is a root native to the Andean region, cultivated for at least 2000 years.
Maca is rich in fiber, a large number of essential amino acids, fatty acids, and other nutrients, including vitamin C, copper, iron, and calcium.
Besides these essential nutrients, this root contains bioactive compounds responsible for benefits to the human body, which has caused a considerable increase in its consumption in the last 20 years worldwide.
Einfach gesagt: Although experimental studies have shown that maca has diverse beneficial effects, more clinical studies are needed to confirm these results.
Gonzales GF et al. · Revista peruana de medicina experimental y salud publica (2014)
Black maca shows the best results on spermatogenesis, memory and fatigue, while red maca is the variety that reverses the benign prostatic hyperplasia and experimentally induced osteoporosis.
In addition, maca reduces the glucose levels, and its consumption is related to the lowering of blood pressure and an improved health score.
Experimental studies have proven that short and long term consumption don't show in vivo and in vitro toxicity.

Li Y et al. · International journal of biological macromolecules (2018)
Maca polysaccharides, some of the major bioactive substances in Lepidium meyenii (Walp.) (Maca), have various biological properties, including anti-oxidant, anti-fatigue, anti-tumor, and immunomodulatory effects, as well as hepatoprotective activity and regulation function.
Although many therapeutics depend on multiple structures of maca polysaccharides in addition to providing sufficient foundations for maca polysaccharide products in industrial applications, the relationships between the pharmacological effects and structures have not been established.
Therefore, this article summarizes the extraction and purification methods, compositions, pharmacological effects, prospects and industrial applications of maca polysaccharides.
Einfach gesagt: Scientific evidence supports the use of mucuna and ashwagandha as phytotherapics for improving serum T concentrations and semen parameters.
Santos HO et al. · Journal of ethnopharmacology (2019)
Scientific evidence supports the use of mucuna and ashwagandha as phytotherapics for improving serum T concentrations and semen parameters.
Despite inconclusive evidence for use of tribulus as a T booster, it may provide advantageous effects on sperm parameters in men with idiopathic infertility.
Nutraceutical strategies and some phytotherapics may also be effective to promote prostate health.
Einfach gesagt: To date, the health claims of maca cannot be fully supported from a scientific standpoint and more research is needed.
Beharry S et al. · Journal of ethnopharmacology (2018)
To date, the health claims of maca cannot be fully supported from a scientific standpoint and more research is needed.
It appears that the indigenous local knowledge about the health benefits of maca has been dragged out of context to fit the demands of a growing market for herbal remedies.
This globalisation (or hype esp. in China) also has had serious consequences for the local producers in Peru.
Einfach gesagt: For each of these plants, information about their traditional uses and current commercialization is also included.
Lock O et al. · Natural product communications (2016)
It is estimated that there are as many as 1400 plant species currently used in traditional Peruvian medicine; however, only a few have undergone scientific investigation.
In this paper, we make a review of the botanical, chemical, pharmacological and clinical propierties of the most investigated Peruvian medicinal plants.
For each of these plants, information about their traditional uses and current commercialization is also included.
