Vitamin A

A fat-soluble vitamin essential for growth and repair, vision and the functioning of the immune system. Used by every organ in your body, and essential for iron metabolism.

B Vitamin Complex

A combination of eight B vitamins, used for increasing energy levels and supporting macro-nutrient metabolism. The B vitamin complex is important for the functioning of the nervous system, skin, red blood cells and eyes. Supplementing with Vitamin B complex will help reduce feelings of tiredness and fatigue.

Vitamin C

Vitamin C, also known as ascorbic acid is required to support the formation of collagen for healthy hair, skin and nails. It is also a powerful antioxidant which helps protect cells against oxidative stress, support the immune system and aid the absorption of iron to reduce tiredness and fatigue – a pretty great all rounder!

Vitamin D

Needed for the absorption of calcium into the body to support the health of bones, muscles and teeth. A lack of vitamin D can lead to bone problems and osteoporosis. Recent studies have found that Vitamin D can also protect the body against cold and flu. The body cannot make vitamin D, it must be supplemented, or taken in through sunlight.

Vitamin E

Found in supplement form and in nuts such as almonds, vitamin E is the healthy skin vitamin. An important one for keeping skin radiant and nourished and helping with healthy ageing.



Found naturally in your joints, glucosamine prevents inflammation and joint pain. It must be supplemented, as there are no food sources of glucosamine.



Iron is needed to produce healthy red blood cells. A lack of iron can result in anaemia, a condition characterised by a lack of oxygenated blood, leading to low energy levels and feelings of fatigue.

Vitamin K
