Dietary supplements are defined by the US Dietary Supplement Health and Education Act (DSHEA) as a vitamin; mineral; herb or other botanical; amino acid; dietary substance for use by man to supplement the diet by increasing the total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of the preceding substances.
Nutraceuticals are dietary supplements that contain a concentrated form of a presumed bioactive substance derived from a whole food. These now present in a non-food matrix and are used to enhance health in doses exceeding those obtainable from whole foods. Evidence-based recommendations require a technical review of the pertinent clinical literature in which publications are rated according to their level of scientific substantiation.
The American Association of Clinical Endocrinologists’ (AACE’s) Nutrition Guidelines Task Force published their evidence-based findings on the clinical use of dietary supplements and nutraceuticals (DS/N) in endocrine practice; some of the findings are summarized throughout this article.
The AACE recognizes that as emerging scientific data become available, these recommendation grades will change.The routine use of unproven therapies with DS/N should be discouraged by physicians. Many DS/N have adverse interactions with other DS/N and with certain medications. In addition, many patients who take DS/N fail to disclose this to their physicians. It is hoped that with continuing education regarding DS/N, physicians
- DS/N with a recommendation grade A (strong evidence of benefit greater than risk);
- DS/N with a recommendation grade B (intermediate evidence of benefit greater than risk) are suitable for second-line treatments;
- Physicians may have no objection to the continued use of DS/N with a recommendation grade C (weak evidence of benefit greater than risk);
- Various DS/N have been used in alternative medicine for unproven uses or situations with excessive risk (grade D).
will be able to communicate more effectively with their patients.
