Cortisol & Stress 8% DV

Magnesium (undefined% DV) calms the nervous system. It blocks NMDA receptors and reduces stress-induced cortisol spikes.

🧘

Cortisol 5% DV

Vitamin B6 (undefined% DV) helps produce serotonin and GABA — calming neurotransmitters that counter cortisol.

🦋

Thyroid 24% DV

Selenium (undefined% DV) converts T4 to active T3. Essential for thyroid function.

🏥

Hypothyroid

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

🏥

Testosterone Low

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

🩸

Iron 11% DV

11% DV. Supports red blood cells and oxygen transport. Low iron = fatigue, brain fog.

Frequently Asked Questions

Does Tofu, extra firm, prepared with nigari affect hormones?
Yes — Tofu, extra firm, prepared with nigari is rich in selenium (24% DV), which Required for T4→T3 conversion (deiodinase enzyme). Selenoproteins protect Leydig cells from oxidative damage.. selenium supports T3 (active thyroid) and Testosterone production. zinc supports Testosterone and DHT production.
Does Tofu, extra firm, prepared with nigari contain anti-nutrients?
Phytates (reduce zinc, iron, calcium absorption 20-60%). Lectins (can irritate gut lining — destroyed by proper cooking). Soaking 12-24h reduces phytates 30-50%. Cooking destroys lectins and protease inhibitors. Fermentation (tempeh, miso) reduces all anti-nutrients. Sprouting increases nutrient bioavailability. Benefits (fiber, protein, minerals) far outweigh anti-nutrient concerns for most people.
