Des réponses simples sur la carnosine, la performance, la récupération et la recherche sur l’application cutanée — ainsi que sur ce que les données scientifiques permettent, ou non, de conclure.
FAQ
Application cutanée ou voie orale
La plupart des données solides concernant la carnosine proviennent de la prise de bêta-alanine par voie orale. L’application d’un gel sur la peau est une autre voie d’administration, avec ses propres données scientifiques — bien moins nombreuses.
Ce que la recherche montre : la bêta-alanine par voie orale augmente la carnosine musculaire au fil des semaines. Ce qu’elle n’a pas mesuré : les effets de la carnosine appliquée sur la peau.
Ce que la recherche montre : la carnosine peut être appliquée et étudiée sur la peau. Ce qu’elle n’a pas démontré : qu’elle atteint le muscle humain en quantités utiles.
Product research
These are studies and reports about topical carnosine gels. They are small, and some have not been independently published. Here is what each one looked at — and what it doesn’t show.
Researchers applied a carnosine–magnesium gel to lab-grown human skin models and measured carnosine passing into and through the skin layers over 24 and 48 hours. Adding magnesium increased delivery to the lower skin layer by up to 60% compared with carnosine alone. This was skin tissue in a lab; it did not measure muscle or exercise.
Read the study (s’ouvre dans un nouvel onglet)Seven elite rugby sevens players did a 12-sprint cycling test twice, once after a topical carnosine gel and once after a placebo gel, triple-blind. Peak power was higher with the carnosine gel in 3 of the 12 sprints; average power, heart rate and perceived effort did not differ. Muscle carnosine was not measured, and the authors say this still needs to be studied.

The gel's delivery system is covered by U.S. Patent No. 10,973,868. A patent describes an invention and how it is meant to work; it is not evidence that a product is effective.
