Each capsule provides 21mg of iron and 12mg of vitamin C in a thoughtfully developed daily formula. Iron contributes to the normal formation of red blood cells and haemoglobin, normal oxygen transport in the body, normal cognitive function, and normal energy-yielding metabolism. Iron and vitamin C also contribute to the reduction of tiredness and fatigue, while vitamin C increases iron absorption. The combination of four iron sources offers a varied approach to iron supplementation in a single capsule. Whether you're looking to top up your daily iron intake or support periods of increased nutritional demand, QuattroFerrin® 21 offers a simple way to include iron as part of your everyday routine. Its Clean Label formula and carefully selected ingredients make it an easy addition to a balanced lifestyle. ### Why BIOGENA is Healf Rather than relying on a single form of iron, QuattroFerrin® 21 combines four different sources, including plant-derived iron from curry leaves and iron-enriched _Aspergillus oryzae_, alongside iron bisglycinate and ferric pyrophosphate.
