Thyroid Zen Defense – 120 capsules

Targeted Thyroid and Stress Response Support with Adaptogens and Immune-Modulating Nutrients*

What It Does
This formula delivers clinically studied nutrients and botanicals that support thyroid function, stress resilience, and immune system balance.* It targets the intersection of the hypothalamic-pituitary-thyroid (HPT) axis and stress physiology to promote healthy hormone synthesis, immune surveillance, and adaptive responses.*

How It Works
• Holy Basil (Holixer® extract): Clinically shown to reduce perceived stress and support cortisol balance, this adaptogen helps buffer stress-related disruptions to the HPT axis.*[1] • Myo-Inositol + Selenium: In combination, this duo has been shown in multiple trials to support thyroid hormone biosynthesis and regulation more effectively than selenium alone.*[2–5] • Myo-Inositol: Supports iodine uptake and organification, essential for thyroid hormone production in thyrocytes.*[4] • Selenium: A cofactor for deiodinase and antioxidant enzymes (glutathione peroxidases, thioredoxin reductases), selenium protects thyroid tissue from oxidative stress and modulates immune signaling.*[5–7] • Shiitake Mushroom (Lentinula edodes): Provides immunomodulatory beta-glucans and polysaccharides that influence natural killer (NK) cell activity, supporting immune surveillance and thyroid-immune interaction.*[8,9] • Immune-Thyroid Interactions: NK cell activity plays a regulatory role in thyroid function, particularly during aging and times of immune activation.*[10]

Who It’s For
Designed for individuals seeking stress resilience and thyroid balance, particularly those seeking optimal thyroid health, stress response balance, or immune-thyroid axis support.*

Special Features
Provides a cohesive formula aimed at the triad of stress, thyroid, and immune health.*
