Supplements can be important for men’s health as they can help fill nutritional gaps in their diet and support specific health concerns such as heart health, prostate health, and immune system function. Men who have restrictive diets, busy lifestyles, or specific health concerns may benefit from taking supplements to help ensure they are meeting their daily nutritional needs. Omega-3 fatty acids can support heart health and brain function, while vitamin D and magnesium can support bone health and immune system function. Also zinc is important for prostate health and supports the immune system.
