Iron
Iron is an essential mineral required for the production of haemoglobin, the protein in red blood cells that carries oxygen throughout the body. It is also involved in energy metabolism, immune function, and cognitive function. Iron deficiency is one of the most common nutritional deficiencies worldwide, particularly among women of reproductive age, pregnant women, and those following plant-based diets. The form of iron used in a supplement has a significant impact on its tolerability and absorption, as standard ferrous sulphate, the form commonly used in pharmaceutical iron tablets, is associated with digestive discomfort and constipation. Gentler chelated forms such as iron bisglycinate and ferrous bisglycinate (Ferrochel) are widely used in food supplements for their improved tolerability and bioavailability. This collection brings together iron supplements across a wide range of forms and formats. The majority of products use iron bisglycinate, available in capsule format from brands including Solgar, Natures Aid, G&G Vitamins, Cytoplan, Health Aid, Balanced, DR VEGAN, and Together Health. Many formulas also include vitamin C, which increases iron absorption, alongside other cofactors such as B12, folate, and copper. Liquid iron formats include Floradix Floravital, hubner Iron Vital sachets, BioCare Nutrisorb liquid drops, a Vitanica iron tonic, and a Kiki Health ionic concentrate. Specialist delivery formats include a BetterYou iron oral spray, a liposomal iron formula from Nutrivital, and a chewable iron tablet from Seeking Health. Wholefood and botanical iron formulas are also included from Terranova, Together Health, and Natura Health Products. An iron phosphate cell salt from New Era in FastMelt dissolve-on-tongue tablet format is also available.
