Nutritive, aphrodisiac, anti-stress, a hormone regulator for post-menopause support: so many benefits that have not yet been scientifically proven.
In 2004, the Anses (Agence nationale de sécurité sanitaire de l'alimentation, de l'environnement et du travail) conducted tests on rats and humans to measure the effects of consuming maca extracts at a dose of 1.5 to 3 grams (similar to the recommended dose). In humans, a beneficial effect on spermatogenesis (sperm formation) and an increase in sexual desire and performance were observed. However, no hormonal changes were measured. In animals, however, researchers measured an increase in progesterone and testosterone. In conclusion, the health agency states that "the hormonal effects highlighted in the animal studies should be taken into consideration, as they suggest a potential risk in humans. Studies in humans are insufficient to conclude that this product is harmless in terms of hormonal balance".
Today, the French National Agency for Food, Environmental and Occupational Health Safety (ANSES) does not officially recommend the consumption of maca.
In fact, according to this agency, the safety of maca powder has not been demonstrated. This means that the danger of using maca has not been demonstrated, but that there is a potential risk. It does appear that the use of maca powder has been linked to cases of high blood pressure, particularly in people with metabolic syndrome.
