Health Condition Relevance

🩸

Anemia

vitamin c, folate, copper. Iron-deficiency is the most common nutritional deficiency. Vitamin C increases non-heme iron absorpt.

🏥

Hypothyroid

selenium, zinc. Thyroid hormone synthesis requires iodine + tyrosine for T4 structure, selenium for T4→T3 conversion.

💪

Testosterone Low

zinc, selenium. Zinc for 5α-reductase and aromatase inhibition. Mg reduces SHBG. D3 activates Leydig cells. Boron si.

Hormonal & Metabolic Impact

🧬 Selenium → T3 (active thyroid), Testosterone (52% DV)

Required for T4→T3 conversion (deiodinase enzyme). Selenoproteins protect Leydig cells from oxidative damage.

🧬 Fiber → Estrogen, Insulin (9% DV)

Binds excess estrogen in gut for excretion (enterohepatic circulation interruption). Slows glucose absorption → lower insulin spikes.

🧬 Sugar → Insulin, Cortisol (25% DV)

Rapid blood sugar spikes → insulin surges → cellular insulin resistance over time. High sugar intake correlates with elevated cortisol.
