A Key Mineral Men May Be Missing for Healthy Testosterone

Testosterone is the primary sex hormone in men. It’s best known for its role in sexual health, but it also helps maintain muscle mass, strength, bone density, mood, and cardiometabolic health.

Many factors affect testosterone levels. Some, such as poor sleep, can reduce production, while others, including strength training, may support healthier levels. One often-overlooked nutrient linked to this hormone is magnesium.

Magnesium and testosterone

Magnesium is an essential mineral involved in more than 300 enzymatic reactions in the body. It supports energy production, muscle and nerve function, blood sugar regulation, protein synthesis, and the creation of ATP, the body’s main source of cellular energy.

Researchers have also examined how magnesium relates to testosterone. Although the exact pathways are still being studied, evidence suggests magnesium may help maintain healthy testosterone levels by influencing how the hormone circulates in the bloodstream and by supporting processes tied to hormone production, including exercise recovery, stress regulation, sleep quality, and inflammation balance.

The research does not show magnesium to be a simple “testosterone booster.” Its effects appear most relevant for people whose magnesium status or testosterone levels may be influenced by the very factors magnesium helps support.

Here are three situations in which magnesium may be especially useful.

If you’re physically active

magnesium + rest and recovery

Men who are active may have the most to gain from getting enough magnesium.

In one study involving both athletes and sedentary men, four weeks of magnesium supplementation increased testosterone in both groups. The largest gains were seen in the athletes, suggesting that magnesium and exercise may work especially well together to support healthy testosterone status.

That may be because magnesium supports muscle contraction, energy metabolism, exercise performance, and recovery, all of which become more important as training volume and intensity rise.

Athletes and highly active people may also need more magnesium because they lose more through sweat and place greater metabolic demands on the body during regular training. Getting enough can help support muscle function, recovery, and the hormonal adjustments that come with exercise.

If you’re stressed

Stress and testosterone often move in opposite directions.

When the body senses ongoing stress, it produces more cortisol, the main stress hormone. Chronically high cortisol can interfere with testosterone production and may contribute to low energy, reduced motivation, and poorer exercise performance.

Magnesium plays an important role in the stress response and in nervous system function. Some research also suggests magnesium needs may rise during chronic stress, creating a cycle in which stress lowers magnesium and low magnesium makes stress harder to handle.

While magnesium is not a replacement for healthy stress-management habits such as exercise, mindfulness, or adequate recovery, maintaining good magnesium levels may help support a more balanced response to everyday stressors.

If you’re not sleeping well

Good sleep is one of the most important factors in healthy testosterone production.

Most daily testosterone release happens during sleep, which helps explain why even a few nights of insufficient rest can negatively affect levels. Research consistently shows a close connection between sleep duration, sleep quality, and hormone health in men.

Magnesium helps regulate the nervous system, supports muscle relaxation, and contributes to healthy neurotransmitters involved in the sleep-wake cycle.

Better magnesium intake will not fully offset chronic sleep deprivation, but it may help support more restorative sleep.

How to increase magnesium intake

Because magnesium is an essential mineral, it must come from food or supplements. A good place to start is by eating more magnesium-rich foods such as pumpkin seeds, leafy greens, legumes, avocado, and whole grains.

Magnesium supplements can also be helpful, especially for people seeking extra support with sleep or stress. This magnesium powder combines 230 milligrams of magnesium with 480 milligrams of tart cherry powder to support rest and relaxation.

The takeaway

Boosting magnesium intake is an underrated but effective way to support testosterone. This mineral plays an important role in several processes that influence hormone health. Men who are physically active, dealing with chronic stress, sleeping poorly, or not getting enough magnesium may benefit most from making sure they get enough of this essential nutrient.
