Detailed Breakdown
Why it works: Cholesterol is precursor for all steroid hormones. Egg yolks provide cholesterol + vitamin D3 + saturated fat for Leydig cell T production.
Recommended intake: 2-3 whole eggs daily
Why it works: Zinc (6.3mg/100g) is cofactor for 5α-reductase (T→DHT). Also provides saturated fat and cholesterol for hormone synthesis.
Recommended intake: 150-200g, 2-3x/week
Why it works: Highest dietary zinc source — single oyster provides 100%+ DV. Zinc inhibits aromatase → less T→estradiol conversion.
Recommended intake: 3-6 oysters, 1-2x/week
Why it works: Vitamin D3 (11μg/100g) activates Leydig cell VDR → increased LH sensitivity. Omega-3 reduces SHBG → more free T.
Recommended intake: 100-150g, 3x/week
Why it works: Magnesium (270mg/100g) reduces SHBG ~10% → more bioavailable free T. Also vitamin E for Leydig cell membrane protection.
Recommended intake: 30-50g/day (handful)
Why it works: Magnesium + boron co-occur naturally. Boron (0.37mg/100g) reduces SHBG and increases free T by 28% in studies.
Recommended intake: 100-200g cooked daily
