Lepidium meyenii (maca) is a plant belonging to the Brassicaceae family cultivated exclusively between 4000 and 4500 m above the sea level (Gonzales, 2017). Maca is traditionally used because of its nutritional and allegedly medicinal properties and is now a famous food supplement, with growing international interest over the last two decades.

In another study, the effects of treatment with Ashwagandha root extract supplementation (675 mg per day for 90 days) on semen parameters and plasma hormone levels were investigated (Ambiye et al. 2013). Ashwagandha is a plant of the nightshade family that has been used as an aphrodisiac to treat male infertility in Ayurvedic medicine. The results of this investigation showed that in the treatment group (n = 21), testosterone levels increased significantly (p < 0.01) by 17%, whilst the control group who were treated with placebo showed no significant increase. In a similar vein, Peruvian Maca (Lepidium meyenii) has been shown to help sexual dysfunction in both males and females (Shin et al. 2010, 44) but studies failed to show a direct link to increased testosterone levels (Bogani et al. 2006, 415–417; Gonzalez et al. 2002, 367–372). Rather, Maca appears to help endurance sport performance by improving oxygen transportation in the body (Stone et al. 2009, 574–576).
Can the biological mechanisms of ageing be corrected by food supplementation. The concept of health care over sick care

The formulation of the nutraceuticals is given in Appendix. In summary, the nutraceuticals “A” and “B” had common ingredients, namely the vitamins B9 and B12, the antioxidant carotenoid astaxanthin as biomass of the algae Haematococcus pluvialis, the anti-inflammatory procyanidins of pine bark extract (Pinus maritima), and the mineral salt zinc bis glycinate. The extract of the phyto-adaptogen Lepidium meyenii (also called Maca) present in nutraceutical “A” was replaced by the extract of Rhodiola rosea in formulation “B.” Acetyl-l-carnitine, that promotes the transportation of fatty acids from the cytoplasm into the mitochondria, and vitamin B6 both present in formulation “A,” were deleted in formulation “B,” whereas the mitochondrial antioxidant ubiquinone Q10 and the amino acid selenomethionine were added to the latter. Also, krill oil rather than fish oil was used as a source of poly-unsaturated omega-3 fatty acids in formulation “B.”

Lepidium meyenii Walpers (maca), which belongs to the Brassicaceae family, is found in the Peruvian Central Andes. Maca has been used as a food and therapeutic product in both traditional and folk medicine (1). The edible portion, which is the storage organ of maca, comprises a transition zone between the hypocotyl and the root. The term “root” will be used to refer to the storage organ in this study. Traditionally, fresh or dried maca is boiled in water (aqueous extract) and consumed as juice (2). Most commercial maca products primarily comprise maca flour. However, the hydroalcoholic extracts of maca are also commercially available as nutraceutical products (3).

Maca (Lepidium meyenii) is a species originated in Peru (1), which belongs to the cruciferous (Brassicaceae) family. It had an increase in consumption in China, mainly through offensive marketing on the internet (2), leading to illegal cultivation and threatening product quality and safety (1, 3). Maca is sold as the ‘Peruvian Viagra’, increasing vitality and longevity, enhancing fertility and libido, as well as alleviating menopausal symptoms in women (1–3).
