Nutritional aspects of ascorbic acid: uses and abuses

R W Vilter

    The Western Journal of Medicine
    |December 1, 1980
    PubMed
    Summary

    Ascorbic acid is vital for bodily functions and treating deficiencies like scurvy. While megadose therapy is explored for various conditions, scientific evidence is lacking, and it may even cause harm.

    Area of Science:

    • Biochemistry
    • Human Physiology
    • Nutritional Science

    Background:

    • Ascorbic acid (vitamin C) is crucial for normal human physiological functions.
    • Higher doses are necessary for treating severe vitamin C deficiency, such as scurvy.
    • Metabolic disorders involving ascorbic acid may necessitate massive doses.

    Purpose of the Study:

    • To review the role of ascorbic acid in human health.
    • To evaluate the scientific basis for megadose ascorbic acid therapy.
    • To assess the safety and efficacy of high-dose vitamin C supplementation.

    Main Methods:

    • Literature review of existing studies on ascorbic acid.
    • Analysis of clinical data regarding vitamin C supplementation.
    • Examination of anecdotal reports on megadose therapy.

    Main Results:

    • Physiological doses of ascorbic acid are essential for health.
    • Megadoses of ascorbic acid have been anecdotally linked to cold prevention, wound healing, and cancer treatment.
    • No robust scientific data support the efficacy of megadose ascorbic acid therapy for these conditions.
    • Some instances of injurious effects from megadose therapy have been reported.

    Conclusions:

    • Ascorbic acid is indispensable for normal bodily functions and deficiency treatment.
    • Current scientific evidence does not substantiate the benefits of megadose ascorbic acid therapy for unproven indications.
    • High-dose vitamin C supplementation may pose risks and should be approached with caution.
