No, age is not a determining factor when it comes to the effectiveness of CarboFix. This nutritional supplement has been designed to improve the fat-burning process for both men and women irrespective of their ages. However, some of the most significant results were found among individuals in their 40s, 50s, and 60s. With that said, you should note that CarboFix is not ideal for pregnant or breastfeeding women as well as individuals with medical conditions unless a practitioner prescribes you.
