Vitamin A plays an important role in ensuring a healthy immune system, cell membranes, vision, growth and reproduction.

Vitamin B helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA. (e.g: folate)

Vitamin C is essential for the healing of wounds, and for the repair and maintenance of cartilage, bones, and teeth.

Vitamin D helps to form and maintain strong bones. It is found in food – in particular in fish, milk, and dairy products – and can also be made by the body after exposure to ultraviolet radiation. A deficiency of vitamin D leads to decalcified bones and the development of rickets. It can also result in bone fragility in the elderly.

Vitamin E protects body tissue from damage caused by unstable substances called free radicals. Vitamin E is also important in the formation of red blood cells and it helps the body to use vitamin K.

Vitamin K plays an essential role in the clotting of blood.
