Nutritional supplements: prevalence of use and contamination
with doping agents
In a review article by van Thurne and colleagues they discuss the role that nutritional supplements play in the lifestyle of a substantial proportion of the population
In addition to vitamins or minerals products, several precursors of anabolic steroids are marketed as nutritional supplements. Another group of commercially available supplements are products for weight loss based upon herbal formulations originating from Ephedra species.
Whilst some supplements indicate the presence of these active compounds, numerous non-hormonal nutritional supplements are to be found that were contaminated with non-labelled anabolic steroids. Stimulating agents other than naturally occurring analogues of ephedrine were detected
A major group using dietary supplements are sportsmen, ranging from amateur level to elite athletes. Besides the possible health risks associated with the use of dietary supplements, athletes should take care not to violate the rules of the World Anti-Doping Agency
The responsibility for knowing what is in these supplements lies with athletes. They remain responsible for substances detected in their biofluids, irrespective of their origin.
The consequences of failing to do this are dire. The drug testing system is now very efficient. Or appears to be.

    Interesting post,

    Nutritional supplements can come in all different shapes and sizes – many different nutritional supplements can make a huge difference in your life. Nutritional supplements are exactly what they imply; they are the vitamins and minerals and other nutrients that your body needs to be healthy. Here are a few of the nutritional supplements available as well as what they are used for.
    Calcium and vitamin D are very important in the development of children, because these supplements help to promote the development of healthy and strong bones. Many different foods contain calcium and vitamin D, but just eating these foods is sometimes not enough.
