What it is

Iron is a mineral that the body needs to function properly. In supplement form, it is usually provided as a salt, which is a chemical compound that allows the mineral to be stable and easier for the body to absorb.

Why it's used

It is primarily used to prevent or treat anaemia, a condition where the blood lacks enough healthy red blood cells to carry oxygen to the body's tissues. This helps to reduce feelings of extreme tiredness and weakness.

How it compares to Vitamin C

While both are often sold together, they serve completely different roles in the body. Vitamin C is a vitamin that helps the body absorb Iron more effectively.

How it's made

Commercial iron supplements are made by reacting iron with an acid to create a stable salt. This resulting powder is then tested for purity and either packed into hard gelatin capsules or pressed into tablets using a binding agent to hold the shape.

What it typically costs

These supplements are generally mid-range in price. This is because the raw iron minerals are relatively inexpensive to source, but the cost increases when companies use specialised coatings to prevent the supplement from irritating the stomach lining.
