Q: Why Do Men Need Different Vitamins Than Women?
A: While many vitamins are essential for both men and women, biological differences mean that men often require higher amounts of certain nutrients. For example:
- Testosterone production relies on vitamins like vitamin D, zinc, and magnesium, which are crucial for muscle mass, energy, and reproductive health.
- Heart health is a major concern for men, and nutrients like coenzyme Q10 (CoQ10) and omega-3 fatty acids help support cardiovascular function.
- Prostate health benefits from vitamin E, selenium, and lycopene, which may reduce the risk of prostate-related issues.
- Muscle recovery and strength depend on protein synthesis, which requires adequate B vitamins, vitamin D, and magnesium.
While women may prioritize nutrients like iron (especially during childbearing years), men need a stronger focus on testosterone support, heart health, and muscle maintenance.
