Ferrous Sulphate

Ferrous sulphate is just one of many forms of the metal element iron.In its natural state, the solid mineral resembles small crystals. The crystals are typically a shade of yellow, brown, or bluish-green — hence why ferrous sulfate is sometimes called green vitriol.

Ferrous Sulphate is a type of iron that's used as a medicine to treat and prevent iron deficiency anaemia.

Iron helps the body to make healthy red blood cells, which carry oxygen around the body. Some things such as blood loss, pregnancy or too little iron in your diet can make your iron supply drop too low, leading to anaemia.

Common side effects include feeling or being sick, constipation and diarrhoea.
