Abstract

BSOUL and TEREZHALMY, Department of Diagnostic Science at the University of Texas Health Science Center, San Antonio, TX, USA, have reviewed (132 references) vitamin C in health and disease. Abstract: Vitamins are essential to maintain normal metabolism and homeostasis in the human body. The amount required varies considerably. Most vitamins are stored only minimally in the human body, with a few notable exceptions such as vitamins A and D. A lack of vitamin C will generate symptoms within weeks and may result in death within 5 to 6 months. The current recommended daily allowance is 75 mg for women and 90 mg for men. This is based on the vitamin's role as an antioxidant as well as protection from deficiency. Higher intakes are generally well tolerated. However a Tolerable Upper Level was recently set at 2 grams based on gastrointestinal problems that sometimes accompany excessive doses. Several population groups need higher daily intakes. These include people with periodontal diseases, smokers, pregnant and breastfeeding women, and the elderly.
