Vitamin C
Vitamin C is a water soluble vitamin. Common sources of Vitamin C are citrus fruits and vegetables. Vitamin C is vital for a healthy body. Vitamin C helps produce collagen which forms tissue in bones and cartilage. It is also vital for healing wounds, a healthy immune system, a well functioning nervous system. It helps in the production of hormones and works as an antioxidant to prevent disease such as cold and flu

These groups include men, the elderly, smokers, diabetics and those with high blood pressure. Possible symptoms include:

Effects on the cardiovascular system - If you have had a deficiency of Vitamin C, this could lead to heart disease. A Vitamin C deficiency could also lead to angina, high cholesterol or high blood pressure.
Increased chance of breathing problems - Scientific research suggests a link between a diet low in Vitamin C and an increased chance of having asthma.
