Purple Maca Root Extract
Also known as: Maca, Peruvian Maca, Andean Maca, Purple Maca, Lepidium meyenii
Overview
Maca (*Lepidium meyenii*) is a biennial herbaceous plant native to the Andes Mountains of Peru. Known for its distinctive tuber, maca has been traditionally utilized for its nutritional and medicinal properties. The purple variety of maca is recognized for its potential health benefits, which include enhancing fertility, boosting energy levels, and improving sexual function. Maca contains a variety of bioactive compounds, including macamides, macaenes, and glucosinolates, contributing to its pharmacological profiles. Research on maca is evolving, with various studies indicating its potential health benefits, particularly in sexual health; however, many studies are criticized for low quality and insufficient sample sizes, warranting more rigorous clinical trials.
Benefits
Maca has shown several evidence-based benefits, particularly in men with mild erectile dysfunction, where improvements in erectile function were noted with a mean difference (MD) of 1.13 (95% CI: 0.64 to 1.61, p = 0.01) across two randomized controlled trials. Additionally, maca may enhance sexual desire, subjective well-being, and alleviate menopausal symptoms in women. Benefits are primarily observed in populations struggling with sexual dysfunction and menopausal symptoms, typically manifesting within an 8 to 12-week supplement regimen. Overall, the evidence for these benefits is of modest strength, influenced by the small sample sizes and variable quality of available studies.
How it works
Maca's bioactive components modulate hormonal pathways, potentially influencing testosterone and estrogen levels. They exhibit antioxidant and anti-inflammatory effects, interacting with the reproductive, nervous, and immune systems of the body. Although the specific molecular targets remain unclear, the interaction of maca's compounds with hormone receptors and involvement in antioxidant pathways suggests a multifaceted mechanism supporting its health benefits.
Side effects
Maca is generally considered safe for most individuals, although well-documented side effects are scarce due to a limited number of large-scale studies. Commonly reported adverse effects such as gastrointestinal discomfort or allergic reactions occur infrequently (1-5%). Serious side effects are rare, with no robust data supporting their prevalence. Special care should be taken for individuals on blood thinners or hormone therapies due to potential interactions with hormonal levels. Additionally, maca is contraindicated during pregnancy and breastfeeding owing to insufficient safety data, warranting caution in those with hormone-sensitive conditions.
Dosage
Recommended dosage ranges for purple maca extract typically fall between 1.2 to 3.0 grams per day, with an effective minimum dose starting at 1.2 grams. For optimal results, consistent daily intake is advised and can be taken with meals to mitigate gastrointestinal side effects. While the maximum safe dosage is not extensively established, daily intake up to 3 grams is common. The effectiveness may vary depending on the form (gelatinized or pulverized) due to differences in bioavailability, influenced also by individual digestive health.
FAQs
Is maca safe for everyone?
