A recent narrative review by Clemesha et al. (28) concluded that many supplements claiming "testosterone-boosting" properties, including formulations using herbs, spices, plants, or their extracts, do not appear to be supported by scientific evidence. Given the increasing body of research on herbal supplementation to support natural hormone production, it presents as a potential treatment option for AD. From the age of 30 onwards, testosterone concentrations in men tend to decline at the rate of ∼1% per year (1–6). The aim of this systematic review was to summarize and critically evaluate randomized controlled trials published on the efficacy of single herbal ingredients on testosterone concentrations, in addition to its fractions or binding proteins, in men (≥18 y). A pilot investigation into the effect of maca supplementation on physical activity and sexual desire in sportsmen. In several studies, maca shows no adverse effects. Maca is most widely known for its potential to support energy levels. Maca also has other benefits. Maca root is classified as an adrenal adaptogen. Maca root is native to Peru and has been cultivated for at least 2,000 years. In women, testosterone is produced in smaller amounts in the ovaries and adrenal glands. Maca root has been used traditionally for its nutritional properties. More research is needed to confirm a direct rise in serum testosterone levels with maca use. Maca also helps nourish the adrenal glands, which may support testosterone levels in both men and women. Over time, maca has been used to support energy levels and promote fertility and stamina. This article examines the scientific evidence to explore whether maca can influence testosterone levels in humans. For fertility and sperm quality goals, research supports 3,000mg daily. For general energy and vitality, 1,500 to 2,000mg daily is effective and well tolerated. For men experiencing low mood, irritability, or performance anxiety — conditions that often compound libido and vitality issues — maca addresses the emotional and psychological dimensions alongside the physical ones. For maximum targeted benefits, some users prefer a pure black maca supplement for gym and cognitive goals alongside BeepWell Gummies for the broader adaptogen stack. Most users report noticeable energy improvements by week 2 to 3 of consistent daily use. This produces clean, sustained energy without jitteriness, crash, or tolerance buildup — one reason maca is increasingly used as a natural caffeine alternative or complementary energy source. For example, some advocates claim that maca can improve energy levels, reduce stress, and even enhance cognitive function. Studies suggest that taking a small dose of maca can increase feelings of well-being and energy in both men and women, and can reduce stress. Another study published in the journal Fertility and Sterility in 2008 found that men who took maca supplements for four months had increased semen volume and improved sperm motility. Fatigue, lower libido, and even depression are all common side effects of low testosterone. As men get older, their testosterone levels naturally decline, which can lead to a host of uncomfortable symptoms. To put it simply, while Maca does offer several health benefits, its role as a direct testosterone booster remains ambiguous. Multiple scientific studies have examined maca's relationship with testosterone levels with mixed results. Studies examining hormone levels in men taking maca supplements have consistently found no significant changes in testosterone compared to placebo groups. However, larger studies in humans are still needed to investigate the effects of maca on female libido and sexual function. This systematic review provides some evidence that certain herbs and herbal extracts increase testosterone concentrations in men. Despite a lack of robust support for herbal supplementation increasing testosterone concentrations in men, there are potential mechanisms of action. Just like coffee or chocolate, maca has a distinct taste. But before you dive into the world of maca, there’s something to note. If you’re a coffee drinker, stirring in a spoon of maca powder can be a good start to your day. She started including a teaspoon of it in her daily smoothie. Men with low testosterone experience vitality improvements because maca optimizes how the body uses available hormones and supports adrenal function. This Peruvian root has been used for over 2,000 years as a performance and vitality enhancer, and modern clinical research confirms significant benefits for libido, energy, endurance, fertility, and mood in men. Several studies show significant increases in testosterone with regular ashwagandha supplementation. ✲ 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.
