Dietary Supplements for Men

If a balanced and healthy diet is not maintained, men may experience deficiencies in certain vitamins and minerals. Men generally require adequate vitamins, minerals, and energy, especially with aging due to physiological differences. Below are the most important supplements for men.

Vitamin D

Vitamin D helps increase calcium absorption to support bone and muscle strength. It may also help maintain healthy testosterone levels, supporting fertility, libido, metabolism, and immune function. It is considered essential for overall men’s health.

Magnesium

Magnesium is vital for blood glucose control, protein synthesis, nerve function, and muscle performance. Rich food sources include spinach, almonds, black beans, and bananas.

Research suggests magnesium supplementation may support testosterone levels, particularly when combined with exercise.

Recommended intake:

Men aged 19–30: 400 mg daily
Men aged 31 and older: 420 mg daily
Supplemental magnesium should not exceed 350 mg daily unless prescribed by a physician.

Boron

Boron is a trace mineral found in raisins, almonds, prunes, and chickpeas. It supports bone health, brain function, and immune response. Men with low fruit and vegetable intake may have lower boron levels.

Omega 3

Omega-3 fatty acids are known for their anti-inflammatory properties. They support heart health, joint health, and brain function. Found in fatty fish, flaxseeds, sardines, and walnuts.

If dietary intake is insufficient, fish oil supplements may help. A minimum of 1.6 grams daily is often recommended.

Zinc

Zinc plays a critical role in:

Strengthening immunity
Accelerating wound healing
Reducing inflammation
Supporting testosterone production and sperm health
Maintaining prostate health

Recommended daily intake for men is 11 mg.
