Research suggests ashwagandha may be more effective than maca for directly increasing testosterone levels. Ashwagandha has more direct evidence for increasing testosterone levels in some studies. When combined with other herbs like Tribulus terrestres, maca might influence testosterone levels indirectly. However, research shows it doesn't directly increase testosterone levels in most men. Many people have questions about maca's effects on testosterone and overall hormonal health. Since maca appears to influence hormone levels, it could potentially complicate certain health conditions. Rather than altering hormone levels, maca appears to work through other pathways to improve sexual drive. Yes — maca root has multiple randomized controlled trials in humans confirming benefits for libido, sexual function, energy, and sperm quality in men. Research shows that maca root likely does not directly increase testosterone levels in men. Moreover, 8 wk of supplementation with an ashwagandha root extract resulted in a significant increase in both muscle strength and testosterone concentrations (62). For example, studies in this review, such as Guo et al. (42), identified a significant increase in lean body mass in addition to a significant increase in testosterone concentrations from 12 wk of supplementation with a fenugreek seed extract. In support of the findings of this review, a recent meta-analysis of clinical trials on fenugreek seed extract supplementation reported a significant increase in testosterone concentrations (68). Fenugreek seed extracts (positive findings in 4 out of 6 studies) and ashwagandha root and root/leaf extracts (positive findings in 3 out of 4 studies) demonstrated the most consistent increases in testosterone concentrations. One randomized, double-blind, placebo-controlled study was conducted examining the effects of a longjack extract (Physta®, manufactured by Biotropics; freeze-dried water extract) on testosterone concentrations (45). A 2019 study suggests combining maca with Chinese chive seed (Allium tuberosum) improved erectile dysfunction in male mice. Maca products have increased in popularity due to claims they may help increase libido and fertility. Its root is a natural remedy that some people use to treat specific health issues, including infertility and low sex drive. It's best to stick to food amounts rather than concentrated supplements if considering maca during these sensitive periods. The hormonal effects could potentially affect pregnancy outcomes or infant development. Traditional use of maca as a food in Peru doesn't necessarily translate to safety as a concentrated supplement for pregnant or lactating women. Due to lack of sufficient safety data, many experts recommend avoiding maca supplements during these periods. A 2022 study in young adult females also showed that maca extract might reduce fatigue. Limited evidence suggests that maca may help improve energy levels and enhance mood. A 2020 study suggests that taking 2 grams (g) of maca per day for 12 weeks may significantly improve sperm concentration compared with a placebo treatment. Shilajit works through direct testosterone and cellular energy pathways; maca works through neurological, endurance, and libido pathways. Some animal studies suggest black maca may support testosterone production, but this has not been confirmed in human trials. Maca improves male vitality, libido, and energy largely independently of testosterone — multiple human trials confirmed benefits with no significant testosterone changes. A pilot study published in the Journal of Ethnopharmacology tested male cyclists who received maca extract for 14 days versus placebo. For men working on fertility, maca combined with shilajit (which also demonstrates sperm quality benefits) represents a comprehensive two-ingredient natural fertility stack with multiple human studies supporting each compound. A 2001 study in Asian Journal of Andrology found that men who took maca for 4 months showed significant improvements in sperm concentration and motility versus baseline, with no changes in hormone levels. ✲ Some small data sets have indicated that it increased testosterone production in the Leydig cells of lab animals. Zinc, vitamin D, and fenugreek also show promise for natural testosterone support. Maca works as an adaptogen that helps the body respond to stress and potentially normalize hormone levels. Research shows it can help with libido issues and may alleviate sexual dysfunction. Here are answers to common questions about this Peruvian root and its potential benefits. Though some research explores maca for managing PMS and menopause symptoms, those with existing hormonal imbalances should consult healthcare providers before use. I've tried various maca brands over the last 20 years and The Maca Team brand is very special. Great energy boost and just feel great all day. I had been using another brand of maca powder and decided to try The Maca Team's. I take 24 products from five to six times a week to increase my well-being and sensual and sexual delights. If you have specific health concerns, speak with a qualified healthcare professional before adding maca to your routine. Maca root is generally considered safe and has no known serious side effects. Its main value appears to lie in supporting overall vitality, drive, energy, and performance. Is maca a replacement for testosterone therapy? Black maca is the most common recommendation for men seeking support for vitality, stamina, and performance.
