Vitamin C is an antioxidant involved in connective tissue metabolism, drug-metabolizing systems, and mixed-function oxidase systems to list a few. Vitamin C deficiency causes scurvy; manifestations include impaired formation of mature connective tissue, bleeding into the skin, weakness, fatigue, and depression.
Preparation: Overnight fasting is preferred. Refrain from eating fruits and from taking vitamin C supplements for 24 hours prior to collection. Please do not exercise prior to testing. It is best that your blood is taken in a rested state.
