Thyroid Zen Defense by Allergy Research Group

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.
• 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.
• Myo-Inositol: Supports iodine uptake and organification, essential for thyroid hormone production in thyrocytes.
• Selenium: A cofactor for deiodinase and antioxidant enzymes (glutathione peroxidases, thioredoxin reductases), selenium protects thyroid tissue from oxidative stress and modulates immune signaling.
• Shiitake Mushroom (Lentinula edodes): Provides immunomodulatory beta-glucans and polysaccharides that influence natural killer (NK) cell activity, supporting immune surveillance and thyroid-immune interaction.
• Immune-Thyroid Interactions: NK cell activity plays a regulatory role in thyroid function, particularly during aging and times of immune activation.

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.
