Iron is found in haemoglobin in red blood cells, which transports oxygen to tissues. Iron deficiency can result in chronic exhaustion, hair loss and a pale complexion. Quest Synergistic Iron also provides thiamin, riboflavin and vitamins B5 and B6 - all of which are essential to the process of energy generation. It also contains folic acid and B12, which are required for normal red blood cell metabolism. It is recommended for those diagnosed with anaemia, menstruating women to help meet additional iron requirements and vegetarians - to help ensure sufficient iron and vitamin B12 intake. The Amino acid chelation creates a gentle ‘iron’ formulation that will not cause constipation. Vitamin C is included to enhance iron absorption, and copper helps to maintain the iron and zinc balance in the body. Suitable for vegetarians and vegans.
