Innovative iron complex with iron bisglycinate
Iron is a real powerhouse – essential for oxygen transport, energy production and a strong immune system. QuattroFerrin® 21 combines a clever blend of four sources of iron, including the proven iron bisglycinate, plus natural vitamin C from camu camu for optimal absorption.
Why iron with iron bisglycinate is worthwhile:
Quadruple power: Iron from curry leaf, koji mushroom, iron pyrophosphate and iron bisglycinate – versatile and effective.
Gentle & well tolerated: Highly bioavailable, also perfectly suited for sensitive individuals.
More energy & performance: Supports haemoglobin formation and helps reduce fatigue.
Strong immune system & focus: Boosts your immune system and ensures clear concentration*.
