The use of nutritional supplements by competitive athletes and fitness enthusiasts alike has many nutritional supplement companies making claims about their products, but how many of them can actually back them up?
Currently there is very little regulation of nutritional supplements
Many companies partake in false labelling - knowingly listing ingredients that are not in their products or worse, not listing ingredients (sometimes banned substances) that are in their products
Even companies with good intentions can be unknowingly providing dangerous products to their customers. Using cheap and inferior raw materials that can expose their products to cross-contamination with banned substances
If you are a drug tested athlete the choice is simple, you should only choose products that are certified to be free of any banned substances by an accredited independent third party company that tests each batch of product produced, that uses ISO 17025 and/or NSF/ANSI Standard 173, and has a proven track record of success with professional and Olympic sport governing bodies.
