Ma vitamine C préférée

J’ai testé les vitamines C de pharmacie mais je retourne toujours à ce produit que je trouve efficace sans etre agressif et qui ne s’oxyde pas rapidement ce qui permet de terminer la bouteille sans perdre les bénéfices (contrairement a d’autres beaucoup plus chers).
Je recommande
