Vitamin C is an essential cofactor for enzymes involved in the synthesis of collagen the chief structural protein in muscles, vascular tissues, skin, bones and cartilage and also plays roles in the synthesis of hormones and neurotransmitters, in immunity, and in prevention of oxidative damage.

Major vitamin C deficiency weakens vascular tissue a condition called scurvy and causes widespread capillary bleeding, bleeding gums, and loosening of the teeth. Lesser deficiencies can be caused by insufficient C intake, physical or psychological stress, smoking, alcohol use, and infections. Symptoms include fatigue, lassitude, loss of appetite, drowsiness, insomnia, irritability, and lowered immunity.

According to clinical studies, vitamin C suppresses cancer, heart disease, Parkinsons, and Alzheimers; it speeds wound healing.

In a study of 700 students, Vitamin C at 1000 mg/hour for the first 6 hours followed by 3000 mg/day reduced cold and flu symptoms by 85%.
