Why are vitamins essential?
Vitamins and minerals are involved in hundreds of different chemical reactions in every part of your body. Some are needed to help release energy from food and to support a healthy immune system, while others are needed for strong bones and teeth, and healthy skin and hair.
Vitamins and minerals help to keep you healthy, so it's important that you get a steady supply in your diet every day. The amount you need will change at different stages of your life. For example, as you grow older you need more vitamin D and less iron and if you're having a baby (or trying for one) it's recommended that you get an extra supply of folic acid as well as a sufficient intake of nutrients before and during pregnancy. |
