An important water-soluble antioxidant
• The absorption of iron
• Synthesis of collagen
• Production of neurotransmitters
• Synthesis of steroid hormones
Why should I take Vitamin C?
Vitamin C prevents scurvy and improves iron uptake from non-heme sources, such as leafy vegetables. Vitamin C is an anti-oxidant that also is used to improve healing of burns, fractures, ulcers, and sunburn. It is a co-factor in the manufacture of collagen to promote skin, bone, and blood vessel integrity. It supports several immune cell parameters, protects lipids from oxidation and encourages the synthesis of carnitine in the presence of lysine and methionine.
What is the recommended dose of Vitamin C tablets?
One tablet supplies 1,000 mg of ascorbic acid, which is half the recognized adult tolerable upper limit. Oxidized Vitamin C, such as from ready-to-drink orange juice, is not freely absorbed across the intestinal mucosa, making supplementation a more reliable resource. Other doses may be recommended by your health care provider.
What are the side effects of Vitamin C tablets?
Side effects of Vitamin C tablets are dose-dependent and GI-related, including nausea and diarrhea from osmotic absorption that pulls water into the colon. In some people, Vitamin C overdoses may precipitate oxalate, urate, or cysteine kidney stones. There are no side effects at recommended doses.
Are there any interactions?
Vitamin C increases chromium uptake. It should not be taken in the presence of high-dose acerola and rosehips to avoid overdose. Large amounts of Vitamin C will show a false increase in AST liver tests or other tests that use colorimetric measurement techniques.
