Thyroid Zen Defense is designed to support three key pathways for maintaining healthy thyroid and immune function. This advanced formula features Holixer® Holy basil extract, clinically studied for its ability to promote cortisol balance and a healthy stress response, both of which are vital for maintaining thyroid health. A combination of selenium and myo-inositol, included in a clinically-supported ratio, work together to promote thyroid hormone production, cellular function, and overall endocrine balance. Time-honored shiitake mushroom extract is included to enhance immune resilience and help maintain healthy immune function by supporting natural killer (NK) cell activity and immunomodulation. With its blend of clinically supported and traditional ingredients, Thyroid Zen Defense offers a multi-mechanistic approach to maintaining optimal thyroid, mood, and immune health.
