Vitamins and minerals play an important role in sport performance. Read on for more information about how iron, B vitamins, calcium, vitamin D and vitamins A, C and E help you to play sports at your best.
Why is iron important?
Iron is a mineral that you need to carry oxygen throughout your body and to your muscles when you play sports. Without enough iron, you can become tired and your muscles may not work at their full potential.
Where can I get iron?
Iron is found in:
- Meat, poultry and fish
- Beans, peas and lentils
- Whole grain and enriched breads and pastas
- Fortified breakfast cereals
- Green leafy vegetables
- Dried fruits, nuts and seeds
- Tofu and
The iron found in animal products like meat, poultry and fish is absorbed best. Iron from plant sources is not as well absorbed, but foods rich in vitamin C like citrus fruit and juices, strawberries, bell peppers or broccoli help your body absorb the iron.
Do I need more iron if I play sports?
You may need more iron if you are:
- a vegetarian who does not eat meat, fish and poultry
- an endurance athlete, who regularly does intense exercise
Low iron can be quite common, especially among women, adolescents and vegetarians who play high intensity sports. These groups should get iron levels checked regularly by their doctor.
If your iron is low, you may need to need to take iron supplements. It is also important to eat iron-rich foods every day. Speak to your health care professional before taking iron supplements.

If your doctor or healthcare provider tells you that you are low in vitamin B12, you may need to take a supplement. This can be in the form of a vitamin tablet or an injection into your muscle. Both forms of the B12 supplement can increase vitamin B12 levels in your blood.
