What do iron and vitamin C do in the body?

  • Iron is an essential trace element that plays a central role in the body. It is responsible for the formation of haemoglobin - the protein in red blood cells that transports oxygen to the organs and tissues. Iron also helps to reduce fatigue and support the immune system.
  • Vitamin C is known for its immune-boosting properties and supports cell protection. It also contributes to collagen formation, which is crucial for healthy skin, cartilage and bones. In addition, vitamin C helps reduce oxidative stress and supports energy metabolism.

Why take iron with vitamin C?

It has been shown that taking vitamin C with iron is particularly effective. Vitamin C promotes the absorption of plant-based iron (non-haem iron), which is more difficult for the body to absorb than iron from animal sources. In combination with vitamin C, plant-based iron is more easily converted into a form that the body can better absorb (Lynch & Cook, 1980) (Hallberg, 1983).

Why is iron better absorbed with vitamin C?

Vitamin C helps iron to be more easily absorbed by your body. It changes iron from a form that is difficult to absorb (Fe³+) to a form that can be better used by your body (Fe²+).

This is especially useful for people who eat a vegetarian or vegan diet, as they often consume less iron from meat. Taking iron with vitamin C regularly can therefore help you get enough iron.

When should you take iron and vitamin C?

It is best to take iron and vitamin C in the morning on an empty stomach. This helps your body to absorb the iron better, as it is not disrupted by other substances such as calcium or caffeine.

If you are sensitive to supplements, you can also take it after a light meal, for example with a juice that contains a lot of vitamin C.

Can you take iron without vitamin C?

Yes, you can also take iron without vitamin C. However, without vitamin C, the iron is absorbed less effectively, which is not ideal if you need a lot of iron. Vitamin C is therefore not strictly necessary, but it does help to absorb iron better, especially when it comes to iron from plant sources.

Which other vitamins should you take with iron?

In addition to vitamin C, there are other nutrients that help with the absorption and functioning of iron. Vitamin B12 and folic acid are important for blood production and, together with iron, can ensure that your body has sufficient reserves.
