Maca Tuber Extract
Also known as: Maca, Peruvian ginseng, Andean radish, Lepidium meyenii
Overview
Maca (Lepidium meyenii) is a biennial herbaceous plant native to the high altitudes of the Andes Mountains. Traditionally used by indigenous peoples for its health benefits, maca is categorized as a herbal supplement and adaptogen. Its root contains a complex mixture of bioactive compounds, including macamides, macaenes, and glucosinolates, whose levels can fluctuate based on cultivation conditions and processing practices. Although the growing interest in maca has led to various studies, the quality of research remains inconsistent, often marked by variability in study designs and supplement preparations. Clinical investigations have primarily examined maca's effects on sexual function, fertility, relief from menopausal symptoms, and enhancement of overall health, with varying degrees of supporting evidence.
Benefits
Maca has shown several potential health benefits, especially regarding sexual health. A systematic review concluded that maca supplementation may positively influence erectile function, particularly in men with mild erectile dysfunction, presenting a mean difference of 1.13 (95% CI 0.64 to 1.61, p = 0.01). While findings on semen quality are less clear, maca has demonstrated positive effects on sexual desire and menopausal symptoms across various studies. Notably, it significantly alleviated hot flushes and other menopausal symptoms in early postmenopausal women. The overall evidence suggests that maca may particularly benefit men experiencing mild erectile dysfunction and women undergoing menopause, despite methodological limitations in many investigations.
How it works
The beneficial effects of maca are attributed to its bioactive constituents, such as macamides, macaenes, and glucosinolates. These compounds are proposed to act through several biological mechanisms, potentially including neuroprotective actions, anti-inflammatory effects, and modulation of immune responses. Such interactions with the reproductive, nervous, and immune systems likely contribute to the enhancement of sexual function and overall well-being associated with maca use, albeit the precise molecular mechanisms remain partially understood.
Side effects
Maca is generally well tolerated with low toxicity, as indicated by preclinical studies. Although adverse effects are generally rare, individual reactions could vary. Current literature does not report frequent (>5%), uncommon (1-5%), or rare (<1%) side effects associated with maca consumption. Nevertheless, caution is warranted for individuals on hormone-regulating medications, as maca may influence hormone levels. It is advisable for people with hormone-sensitive conditions, pregnant or breastfeeding women, and those with chronic health issues to consult healthcare professionals before using maca, due to limited comprehensive safety data.
Dosage
The commonly recommended dosage range for maca is between 1.5 and 3 grams per day, typically divided into multiple doses. While there are no well-established minimum effective doses, research suggests that daily doses ranging from 1 to 5 grams can yield beneficial effects without significant side effects. Timing of supplementation is flexible, but many experts recommend taking maca before meals to optimize absorption. Additionally, the form of maca may affect its bioavailability, with gelatinized or fermented versions believed to offer enhanced absorption compared to raw maca. Individuals are encouraged to monitor their responses to different preparation methods.
