Vitamin C is a water soluble vitamin found in many fruits and vegetables including oranges, peppers, strawberries, blackcurrants, tomatoes and potatoes.
Vitamin C is crucial for growth and repair of tissues, healing wounds, healthy bones and teeth and assisting the body with collagen production and iron absorption. It is also an antioxidant so fights off damaging free radicals.
What might a low result mean?
Vitamin C deficiency can lead to scurvy although this is rare. Signs of a deficiency are tiredness, weakness, muscles and joint pain, bruising, small bruise-like spots, dry skin, splitting hair, swelling and bleeding gums, nose bleeds, tooth and bone weakness and problems fighting infections.
Low levels of vitamin C are more common amongst smokers.
What might a high result mean?
As vitamin C is water-soluble it is unlikely to accumulate in the body. Taking vitamin C supplements can cause some reactions such as an upset stomach and diarrhoea.
