Regulatory framework and categorization

Groups with solid evidence vs. questionable products

The performance-oriented supplement industry is immensely lucrative and plagued by aggressive marketing, requiring stringent selection criteria.

To protect the health and careers of exercisers, various institutions have developed a letter-based classification framework, separating products according to the weight of their scientific evidence.

The highest level groups together those inputs that have irrefutably demonstrated their efficacy in clinical trials.

Here we find formulations rich in proteins, electrolytes or creatine, whose use is fully justified in specific protocols.

A second tier contains promising substances, such as certain polyphenol or collagen extracts, which show initial positive results but require further research before being universally recommended.

Finally, there is a large group of compounds that completely lack scientific backing to validate their purported athletic benefits.

Investing resources in these products is not only futile, but diverts attention from the real pillars of nutrition.

Warnings about contaminated formulations

At the darker end of this classification are products that pose an imminent danger to both human physiology and competitive integrity.

This category includes synthetic stimulants and hormone disruptors whose use is strictly prohibited by the world's sports regulatory bodies.

The greatest risk lies in the fact that many of these toxins are hidden in multi-ingredient formulas or enter permitted supplements through cross-contamination during the manufacturing process in negligent laboratories.

Consuming an adulterated product, even accidentally, can trigger severe hepatic collapse or result in an irreparable doping violation.
