摘要：The use of natural supplements, included
herbal supplements, by athletes has become an habit which often lacks any valid scientific rationale. It appears
evident that this habit may entail health risks (including more or less serious adverse effects), consequent
either: 1) to the pharmacodynamic effects of the drugs at high doses; or 2) to the occurrence of accumulation
especially when their administration is not justified by a reduced synthesis or an increased demand; or 3) to
the occurrence of intolerance; or, finally, 4) to the presence of not labelled ingredients. The abuse of this kind
of products always entails risks to the consumer, not only to the elite athlete, that can incur an adverse
analytical finding on the occasion of anti-doping tests, but also to the amateur sportman, for the possible
occurrence of adverse drug reactions (ADR).
