The Active Ingredient Is: Thymic Protein A (Protein Polypeptide)

Thymic Protein A is a biologically active protein polypeptide involved in immune regulation. This primary ingredient is sourced within the product as a thymic protein A component designed for sublingual delivery. It functions as the key active ingredient supporting immune-related processes.

This form is described as a thymic protein A polypeptide derived from thymic tissue and is presented in a manner suitable for sublingual absorption, with other ingredients serving as carriers. This formulation focuses on immune support through this main component, with additional ingredients playing supporting roles.

What Does Thymic Protein A Do?

Thymic Protein A is involved in regulating and balancing immune system function and plays a role in activating T-lymphocytes, contributing to immune surveillance and response. The mechanism aligns with normal immune operation and body defences.

Its activity is described in the context of supporting the body to cope with common immune challenges and aging, with the formulation designed to provide natural support for immune function in line with standard understandings of thymic protein activity.
