Organic Maca Gelatinized Powder
Also known as: Maca, Peruvian ginseng, Organic Maca Gelatinized Powder, Lepidium meyenii
Overview
Maca (*Lepidium meyenii* Walp.) is a biennial plant indigenous to the high-altitude Andes Mountains, traditionally valued for its nutritional and medicinal properties. The gelatinized powder form is derived from dried maca root, which undergoes a heating process to remove starch. This process enhances its digestibility and improves the bioavailability of its active compounds, such as macamides, macaenes, and glucosinolates. Maca is primarily utilized as an adaptogen and functional food, with its main applications focusing on improving sexual health, fertility, energy levels, and alleviating menopausal symptoms. While research on maca is evolving, it includes a growing number of clinical trials. However, there is a recognized need for more large-scale, high-quality randomized controlled trials to solidify its efficacy across all claimed benefits. The current evidence base shows varying quality, with systematic reviews indicating mixed results, particularly concerning fertility outcomes.
Benefits
Maca offers several potential benefits, with varying strengths of evidence: - **Sexual Health:** Clinical studies, including randomized controlled trials, suggest that maca may improve sexual desire and alleviate erectile dysfunction, particularly in men with hypogonadism or general sexual dysfunction. Doses typically range from 2-3 g/day over 12 weeks. The evidence for this benefit is moderate to strong, with consistent findings across several smaller studies. - **Energy and Fatigue:** A double-blind randomized controlled trial found that 3 g/day of black or red maca significantly increased self-reported energy levels compared to a placebo over a 12-week period. This suggests a moderate level of evidence for its role in combating fatigue and boosting energy. - **Menopausal Symptoms:** Preliminary evidence indicates that maca may help alleviate certain menopausal symptoms, such as hot flashes and mood swings. However, the data are limited, and more robust, larger-scale studies are needed to confirm these effects, making the evidence strength weak to moderate. - **Antioxidant and Anti-inflammatory Effects:** Preclinical studies have demonstrated that maca can enhance the activity of endogenous antioxidant enzymes like glutathione peroxidase and superoxide dismutase, and exhibit anti-inflammatory properties. While promising, these findings are primarily from in vitro and animal studies, requiring human clinical trials for confirmation. The evidence strength for these effects in humans is currently weak. - **Fertility:** A meta-analysis of randomized controlled trials showed inconclusive effects on semen quality parameters (sperm concentration, motility). While some individual studies reported improvements, the overall meta-analysis did not find a statistically significant improvement in sperm concentration, indicating mixed results and weak evidence for this specific benefit.
How it works
Maca's therapeutic effects are attributed to its unique blend of bioactive compounds, including macamides, macaenes, and glucosinolates. These compounds are believed to modulate neuroendocrine function, potentially influencing the regulation of hormones and supporting sexual function. Its adaptogenic properties may help the body adapt to stress and maintain homeostasis. The antioxidant effects of maca are thought to stem from its ability to upregulate endogenous antioxidant enzymes, thereby reducing oxidative stress at a cellular level. The gelatinization process, which removes starch, significantly enhances the bioavailability of these active metabolites, facilitating their absorption and utilization by the body. While the exact molecular targets are still under investigation, hypotheses include interactions with the hypothalamic-pituitary-gonadal axis and nitric oxide pathways, contributing to its observed effects on energy and sexual health.
Side effects
Maca is generally considered well-tolerated, with a low incidence of adverse effects reported in human studies. The most commonly observed side effects are mild gastrointestinal symptoms, such as bloating or stomach upset, occurring in approximately 2.5% of individuals at doses up to 6 g/day. These symptoms are typically transient and resolve with continued use or dose adjustment. No significant drug interactions have been firmly established, but due to limited research, caution is advised when combining maca with medications, particularly those affecting hormone levels or blood pressure. Contraindications are not well-defined, but individuals with hormone-sensitive conditions (e.g., certain cancers) or thyroid issues should consult a healthcare professional before use, as maca may influence hormonal balance. Pregnant and breastfeeding women should also avoid maca due to insufficient safety data. Long-term safety data are currently lacking, as most clinical studies have durations of three months or less. Therefore, prolonged use beyond this period should be approached with caution and under professional guidance.
Dosage
For optimal benefits, the minimum effective dose of gelatinized maca powder is typically around 1.5-2 g per day, particularly for supporting sexual health and energy levels. Clinical studies commonly utilize doses ranging from 2 to 3 g per day, administered orally. These doses are generally well-tolerated. The maximum safe dose observed in studies is up to 6 g per day, which has shown good tolerance in short-term use. To achieve noticeable effects, supplementation duration in studies typically ranges from 8 to 12 weeks. Gelatinized maca powder is recommended over raw maca powder due to its improved digestibility and enhanced bioavailability of active compounds, as the starch has been removed. It can be mixed into beverages, smoothies, or food. There are no specific timing considerations, but consistent daily intake is crucial for efficacy.
FAQs
Is gelatinized maca powder more effective?
Gelatinization improves digestibility and absorption by removing starch, which may enhance the bioavailability of active compounds. While direct comparative efficacy data are limited, it is generally preferred for better tolerance and potential absorption.
How soon do benefits appear?
Most clinical studies report that the beneficial effects of maca, particularly for sexual health and energy, typically become noticeable after 8 to 12 weeks of consistent daily supplementation.
Is maca safe long-term?
Long-term safety of maca is not well-established, as most studies have durations of three months or less. Short-term use (up to 3 months) appears to be generally safe and well-tolerated.
Does maca improve fertility?
Evidence regarding maca's effect on fertility, specifically semen quality, is inconclusive. A meta-analysis found mixed results and no statistically significant improvement in sperm concentration, suggesting more research is needed.
Are there side effects?
Maca is generally well-tolerated. The most common side effects are mild gastrointestinal discomfort, such as bloating or stomach upset, which occur in a small percentage of users and are usually transient.

It notes that while maca is generally safe, much of the evidence comes from preclinical and small clinical trials, indicating a need for more robust human studies to confirm its efficacy and mechanisms of action.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC9468664/ – This systematic review and meta-analysis evaluated the effects of maca on male fertility, specifically semen parameters. It concluded that based on the available randomized controlled trials, maca showed no statistically significant effect on sperm concentration and presented mixed results for other semen parameters, indicating inconclusive evidence for its role in improving male fertility.
- https://www.hims.com/blog/maca-root-men – This source references a double-blind randomized controlled trial (Brown et al. 2016) which found that 3 g/day of black or red maca significantly increased energy levels in 175 adults over 12 weeks compared to a placebo. This study provides strong evidence for maca's potential in boosting energy and combating fatigue.
