Neurobiologix T3/T4 Support (formerly T3/T4 Plus)
Natural Thyroid Support
T3/T4 Supportis a targeted nutritional formula designed to promote healthy thyroid function by supporting the balanced production, conversion, and activity of thyroxine (T4) and triiodothyronine (T3). This comprehensive blend includes key bioactive compounds such as forskolin, zinc citrate, and bovine-derived glands, each contributing distinct support for thyroid physiology.
Forskolin (from Coleus forskohlii) has been shown to modulate cyclic AMP (cAMP) signaling pathways, which may positively influence thyroid hormone synthesis and activation, thereby supporting metabolic homeostasis. Zinc citrate, a highly bioavailable form of zinc, is critical for the enzymatic conversion of T4 to T3 and for the structural integrity of thyroid hormone receptors. The inclusion of bovine thyroid and adrenal glandular extracts provides tissue-specific peptides and cofactors intended to support the endocrine system’s functional resilience, particularly along the hypothalamic-pituitary-thyroid (HPT) and hypothalamic-pituitary-adrenal (HPA) axes.
Key Benefits:
Supports endogenous thyroid hormone synthesis and activity
Facilitates peripheral conversion of T4 to T3
Provides glandular support for thyroid and adrenal function
Promotes a healthy metabolic rate and energy production

More Info.
At the heart of the formula are forskolin, zinc citrate, and bovine thyroid and adrenal gland extracts, each chosen for their specific role in supporting thyroid performance:
Forskolin, derived from Coleus forskohlii, helps activate cellular pathways involved in thyroid hormone production and activation, supporting healthy metabolism and energy levels.
Zinc citrate, a highly absorbable form of zinc, is crucial for the conversion of T4 into the more active T3 hormone and supports optimal receptor function for thyroid hormones.
Bovine thyroid and adrenal glands deliver organ-specific nutrients to nourish and reinforce the body’s own thyroid and adrenal systems, promoting balanced hormone output and helping maintain resilience in the adrenal-thyroid axis.
Support your thyroid naturally with T3/T4 Support: a comprehensive solution for energy, hormonal balance, and well-being.
