The Active Ingredient Is: Astragalus membranaceus (root extract)

Astragalus membranaceus is a herb used in traditional medicine to support immune function and overall resilience. This form is derived from the root as an extract and is commonly used to facilitate normal immune processes.

This ingredient is included for its potential to participate in immune activity, with the root extract representing the primary botanical component in Phytogen.

What Does Astragalus membranaceus Do?

Scientific research suggests astragalus root extract promotes immune activation and supports interferon production, contributing to normal immune function.

EFSA-aligned interpretation notes the extract plays a role in supporting physiological immune responses as part of a balanced immune toolkit.
