ContextThe problems of doping in sport and the increasing use of nutritional supplements by athletes are issues that intersect to the degree that a large number of supplements may contain substances that are banned in sport. Many supplements contain substances that are associated with significant health hazards. Athletes consuming such supplement products may jeopardize their sporting status, and their health. ObjectivesTo clarify and summarize the current status of dietary supplements in… 

Use of nutritional supplements in sports: risks, knowledge, and behavioural-related factors.

In addition to the necessity of an appropriate regulation of dietary supplements, nutritional education and scientifically sound guidance for athletes is required.

Nutritional supplements: prevalence of use and contamination with doping agents

The present review attempts to address the issues concerning the use of nutritional supplements and the detection of doping agents as contaminants in dietary supplements.

Contamination of dietary supplements and positive drug tests in sport

There is now evidence that some of the apparently legitimate dietary supplements on sale contain ingredients that are not declared on the label but that are prohibited by the doping regulations of the International Olympic Committee and of the World Anti-Doping Agency.

Assurance Issues in the Use of Dietary Supplements , with Special Reference to Protein Supplements 1 , 2

The risk associated with the use of protein powders produced by major manufacturers is probably low, and the risk can be further reduced by using only products that have been tested under one of the recognized supplement quality assurance programs that operate in various countries.

Quality assurance issues in the use of dietary supplements, with special reference to protein supplements.

The risk associated with the use of protein powders produced by major manufacturers is probably low, and the risk can be further reduced by using only products that have been tested under one of the recognized supplement quality assurance programs that operate in various countries.

Dietary supplement use by adolescents.

The unrestrained consumption of dietary supplements should be avoided, since, besides the lack of evidence that such practice will lead to improvement of performance, it exposes adolescents to several adverse effects.

The continuing story of nutritional supplements and doping infractions

The NZVT experience has shown that paper-based quality systems are still prone to possible contaminations, which leads to the conclusion that the best possible solution for athletes who wish to use nutritional supplements must include laboratory-based analysis for doping substances, preferably repeated for every new batch.

Cardiovascular toxicities of performance-enhancing substances in sports.

The current evidence regarding cardiovascular risk for persons using anabolic-androgenic steroids including 2 synthetic substances, tetrahydrogestrinone and androstenedione (andro), stimulants such as ephedra, and nonsteroidal agents such as recombinant human erythropoietin, human growth hormone, creatine, and beta-hydroxy-beta-methylbutyrate is examined.

It is argued that antidoping regulators may wish to review current data gathering and information provision systems so that the problem of inadvertent doping can be more directly assessed as a factor in sports doping overall.

Clinicians should be aware of the problems that such drug use can engender, and be sensitive to the possibilities of such abuse in caring for athletes and young patients, particularly in those presenting with unusual or unanticipated cardiovascular signs and symptoms.



Sport nutritional supplements: quality and doping controls.

The combination of theGC/MS and the GC/C/IRMS offers a powerful tool to discriminate between the natural and synthetic origin of the urinary steroids, which cannot be proven by the sole identification of the substances in the urine.

These mislabeling problems show that the labels of the dietary steroid supplements studied herein cannot be trusted for content and purity information and athletes who use them are at risk for positive urine test results.

Over-the-Counter Drug Use in Gymnasiums: An Underrecognized Substance Abuse Problem?

Millions of men and women are currently using potent drugs, widely sold over the counter as ‘supplements’, despite their known adverse effects, unknown long-term risks, and possible potential for causing abuse or dependence.

American College of Sports Medicine roundtable. The physiological and health effects of oral creatine supplementation.

Although Cr supplementation exhibits small but significant physiological and performance changes, the increases in performance are realized during very specific exercise conditions, suggesting that the apparent high expectations for performance enhancement, evident by the extensive use of Cr supplementation, are inordinate.

Caffeine and Endurance Performance

A review of the literature suggests that caffeine at doses of approximately 6 mg/kg is not of ergogenic benefit to high intensity exercise performance, but similar doses are ergogenic in endurance exercise performance.
