“My supplements are batch tested – surely that covers the risks?”

Actually, no it doesn’t!

Synergy Biologics - Batch Tested Supplements Manufactured in the UK

Of course, for an athlete who is in the anti-doping testing pool, being assured that your particular batch of supplements is “clean” is a critical factor. But do you ever think of asking your supplement manufacturer about their validation processes that deal with other risks that can affect health and performance?

There is a whole host of risks associated with supplements aside from whether they contain prohibited substances or not. What if your capsules / powders etc contains toxic, or bacterial contamination? That’s not going to show up in a test for prohibited substances, and so every athlete or sports nutritionist who takes or procures supplements should be conducting ongoing risk analyses.

Have you ever asked your supplement supplier whether they manufacture in their own dedicated manufacturing/production facilities? So many supplements are produced by contract manufacturers, and many suppliers merely brand and market them. What’s more, the standards for Good Manufacturing Practice in the food supplement industry is far less rigorous than those required for licensed pharmaceuticals.

Even for licensed pharmaceuticals, cross contamination is not prohibited as long as the contamination does not lead to clinically significant outcomes.

Can elite sport really afford to leave such things to chance with food supplements?

So go ahead and ask yourself, and your supplier:

  • Are there choices available that cater for cultural or religious practices?

  • Do your supplements meet the equivalent of NHS requirements for non-licensed products?

  • Are your supplements actually produced by a manufacturer that obtains independent validations and verifications for contamination, active ingredient quantification?

  • Are the raw materials used in the manufacture sourced from validated suppliers?

  • Can your supplier confidently vouch for the cleanliness and hygiene in the manufacturing facility?

  • Is product quality consistent?

  • Are the product handling, storage and history documented?

  • Is your supplement supplier in full control of the manufacturing processes and environment?

At Synergy Biologics, we can confidently answer “Yes” to all of these, and many more searching questions. And these facts should reassure everyone taking or procuring supplements for use by athletes:
