Chromium is an essential trace mineral that plays a crucial role in various physiological functions, particularly in glucose metabolism, insulin sensitivity, and overall metabolic health. While naturally present in foods such as whole grains, broccoli, green beans, and lean meats, chromium supplementation has gained popularity due to its potential health benefits, such as improving glucose metabolism, regulating serum lipid levels, and reducing body fat parameters that often decline with aging. The most bio-available form, chromium picolinate, has been extensively studied for its impact on men’s health, including its influence on testosterone production, muscle growth, weight management, and cardiovascular function.
One of the primary benefits of chromium for men is its potential to support testosterone levels. Studies suggest that chromium enhances insulin sensitivity, which plays a key role in regulating sex hormones, including testosterone. Insulin resistance has been linked to lower testosterone levels, contributing to issues such as reduced libido, fatigue, and muscle loss. By improving insulin function, chromium supplementation may help maintain optimal testosterone levels, particularly in men with metabolic disorders such as diabetes and obesity.
Additionally, chromium’s role in reducing oxidative stress may support testicular function and sperm quality. Research indicates that oxidative damage negatively impacts sperm motility and viability. Chromium’s antioxidant properties help protect reproductive cells from free radical damage, thus contributing to better reproductive health.

Tongkat ali (Eurycoma longifolia), also known as longjack or Malaysian ginseng, is an herb from Southeast Asia. The main bioactive components in tongkat ali are the quassinoid compounds (eurycomanone and eurycomanol), eurycolactones, canthin-6-one metabolites, eurylene and teurilene (derivatives of squalene) and eurypeptides. Supplementation may increase total testosterone in healthy and hypogonadal men, improve erectile function and alleviate symptoms of erectile dysfunction, increase fertility, and enhance sexual function and well-being. One study found evidence of an anxiolytic (anxiety and stress-reducing) effect of tongkat ali.
Tongkat ali’s effects on male sexual enhancement are primarily attributed to eurycomanone, which has steroidogenic activity. Eurycomanone has been shown to have anti-estrogenic effects. It inhibits the aromatase enzyme and prevents the conversion of testosterone to estrogen in the Leydig cells of the testes, the primary site of sperm production in men.
When given in a dose of 200-600 mg/day, Tongkat ali appears to increase free and total testosterone levels in men, although effects seem to be most noticeable in men with hypogonadism (testosterone levels <300 ng/mL).
