Product Features

Xendurance is a supplement company specializing in supplements designed to improve health and wellbeing. The company does not sell multiple products, but rather focuses on a select few. The products include Extreme Endurance, a supplement designed to reduce lactic acid in the muscles. Extreme Xecute, a protein-based supplement designed to promote lean muscle growth. The final supplements include Extreme Immune Boost, a vitamin supplement and Extreme Gut Endurance, a blend of probiotics. All of the supplements are available on the website. When we compared the supplements to similar products, we noticed the prices were a bit more expensive.

Throughout the website, there was information pertaining to clinical research associated with the supplements. Typically, supplement companies do not publish the findings, but Xendurance included the studies on the website. This is a positive for Xendurance. Dieters have the opportunity to see what works and what does not. The company maintains the results are provided by a third party testing site with no affiliation to Xendurance.

    I was looking for the side effects of this product. I brought this product on the 2 of Oct and received it on the 4th. I took it for about three days and now I’m having headaches, dizzy spells and I can eat. However I’m gaining weight.
