Water iron supplements are a type of dietary supplement that are designed to increase the levels of iron in the body. Iron is an essential nutrient that plays a vital role in the production of haemoglobin, which carries oxygen in the blood. Low levels of iron can lead to anaemia, which can cause fatigue, weakness, and other health problems. Water iron supplements come in various forms, including tablets, capsules, and liquids, and are suitable for individuals who have trouble absorbing iron from food or who have increased iron requirements due to pregnancy or heavy menstrual bleeding.
