Why Men Have Unique Mineral Needs

Men’s mineral needs differ from women’s due to:

• Testosterone production — Requires zinc, magnesium, and vitamin D3
• Prostate health — Selenium and zinc are critical for prostate function
• Higher muscle mass — Greater magnesium and potassium needs
• Semen production — Zinc and selenium are required for sperm quality
• No menstrual iron loss — Men rarely need iron supplementation

The Men’s Mineral Priority List

Tier 1: Essential

Tier 2: Highly Recommended

Tier 3: As Needed

Zinc: The Testosterone Mineral

Zinc is the single most important mineral for male hormonal health:

How zinc supports testosterone:

• Required for the enzyme 17β-HSD that converts androstenedione to testosterone
• Supports Leydig cell function in the testes
• Regulates aromatase (the enzyme that converts testosterone to estrogen)
• Deficiency causes hypogonadism (low testosterone)

Clinical evidence:

• Zinc supplementation in marginally zinc-deficient elderly men increased testosterone from 8.3 to 16.0 nmol/L over 6 months
• In young men with normal zinc status, additional zinc does NOT further increase testosterone
• Key insight: Zinc only boosts testosterone if you’re deficient

💡 Testing: Ask for serum testosterone and serum zinc levels. If zinc is below 70 mcg/dL, supplementation is likely to help.

Selenium: The Prostate Mineral

The prostate contains the highest selenium concentration in the body. Research shows:

• Men with higher selenium levels have lower prostate cancer risk
• Selenium supports sperm motility and morphology
• Selenium reduces thyroid antibodies (relevant for overall hormonal health)

Best sources: Brazil nuts (1-2/day), tuna, sardines, eggs. If supplementing, 100-200mcg selenomethionine daily.

Magnesium: The Vitality Mineral

Magnesium supports male health through:

• Testosterone production — Required for the enzymes that synthesize testosterone
• Muscle function — Supports strength and recovery
• Sleep quality — Deep sleep is when testosterone is produced
• Blood pressure — Cardiovascular health affects sexual function
• Insulin sensitivity — Low insulin resistance supports higher testosterone

What Men Should Avoid

❌ Iron supplements — Unless diagnosed deficiency. Excess iron is pro-oxidative and accumulates in men. ❌ Calcium above 1000mg — May increase prostate cancer risk in some studies ❌ Soy isoflavones — May have estrogenic effects at high doses ❌ 5-alpha reductase inhibitors (without doctor) — Can cause sexual side effects ❌ High-dose zinc above 40mg — Can cause copper deficiency and GI issues
