Biogena QuattroFerrin® 21 is an innovative iron preparation designed for optimal absorption, effectiveness, and gentle digestion. This premium formula features the unique QuattroFerrin® blend, which combines four distinct iron compounds that utilize different absorption pathways in the body: plant-based iron from Curry Leaf extract and Koji Mushroom (fermented with iron), alongside highly bioavailable organic Iron Bisglycinate and well-tolerated Iron Pyrophosphate.
This multi-faceted approach aims to maximize iron uptake while minimizing the potential for gastrointestinal side effects often associated with iron supplementation. The formula is further enhanced with natural Vitamin C sourced from Camu-Camu berries, which significantly improves iron absorption.
QuattroFerrin® 21 is ideal for individuals needing to replenish iron stores, combat fatigue associated with iron deficiency, and support energy production and red blood cell formation. It offers a well-tolerated, effective solution for maintaining healthy iron levels.
