Macamides And Macaenes
Also known as: Lepidium meyenii, Maca, Peruvian ginseng
Overview
Maca (*Lepidium meyenii*) is a plant native to the Andean region, cultivated for its edible root. It is often referred to as Peruvian ginseng, though it is not related to ginseng. Maca contains various bioactive compounds, including macamides, macaenes, alkaloids, glucosinolates, and polyphenols. Traditionally, maca has been used to enhance fertility, energy, and endurance. Modern applications include improving physical performance and sexual function. Maca is rich in nutrients and bioactive compounds, which contribute to its potential health benefits. Research on maca and its components is growing, with increasing studies on its effects on physical performance and sexual health. However, more high-quality studies are needed to fully understand its efficacy and safety.
Benefits
Maca supplementation has demonstrated potential benefits in improving physical performance, with significant effects observed in studies using forced swimming tests, rota-rod tests, and grip strength tests. A meta-analysis reported a large effect size (SMD = 2.26) for improvements in forced swimming tests. Maca may also enhance sperm count and motility, suggesting benefits for male fertility. Secondary benefits include potential improvements in sexual function and stress reduction, although the evidence for these effects is less robust. These benefits may be particularly relevant for athletes seeking to enhance performance and individuals experiencing sexual dysfunction. Benefits may be dose-dependent and require consistent supplementation over time.
How it works
The bioactive compounds in maca, particularly macamides and macaenes, are believed to influence energy metabolism and hormonal balance, contributing to enhanced physical performance and sexual function. Maca interacts with the endocrine system, potentially affecting hormone levels related to fertility and energy. While specific molecular targets are not well-defined, maca may influence pathways related to energy production and hormonal regulation. The absorption and bioavailability of macamides and macaenes are not extensively studied, but they are believed to be influenced by the form of maca supplementation (e.g., raw vs. gelatinized).
Side effects
Maca is generally considered safe when consumed in traditional amounts. However, high doses or prolonged use may have unknown effects. Common side effects are not well-documented, but gastrointestinal upset is possible. Uncommon side effects include the potential for allergic reactions or interactions with medications. Rare side effects have insufficient data to determine. Maca may interact with blood thinners or medications affecting hormone levels, though evidence is limited. It is contraindicated in pregnancy and breastfeeding due to insufficient safety data. Individuals with thyroid issues should consult a healthcare provider due to potential effects on thyroid function. Caution is advised with high doses due to the lack of established maximum safe dose.
Dosage
While a minimum effective dose is not well-established, studies have used doses ranging from 500 mg to several grams per day. Higher doses may be more effective for physical performance, but optimal ranges are not clearly defined. A maximum safe dose has not been established, so caution is advised with high doses. Consistent daily supplementation is recommended. Gelatinized maca may be more bioavailable than raw forms. Bioavailability may be influenced by the form of maca and individual digestive health. No specific cofactors are required for maca supplementation.
FAQs
How should I take maca?
Maca can be consumed as a supplement or added to food. Choose a reputable brand and follow recommended dosages. Consistent daily use is recommended for optimal benefits.
Is maca safe?
While generally safe, maca should be used with caution in certain populations, such as pregnant women or individuals with thyroid issues. Consult a healthcare provider if you have concerns.
What results can I expect from taking maca?
Improvements in physical performance and sexual function may be observed over time with consistent supplementation. Maca is not a substitute for medical treatment and should be used under the guidance of a healthcare provider.
Can maca be taken with other medications?
Maca may interact with blood thinners or medications affecting hormone levels. Consult with a healthcare provider before combining maca with other medications.
