Marathon / Ultra Marathon

When it comes to tough events, Marathon and Ultra-Marathon races rank as the toughest events you will mentally and physically take on, so that RECOVERY is key to continue building fitness, preventing injuries, repairing broken-down muscles - so you can race faster.

Xendurance provide the best running supplements for training and racing.

When you're walking or running very slowly, your muscles burn modest amounts of carbohydrate and produce modest amounts of lactic acid, which doesn't do you any harm.

As you run faster, however, your muscles burn more carbs and produce more lactic acid, which quickly breaks down into a good guy (lactate) and a bad guy (hydrogen ions).

The hydrogen ions are bad because they lower the pH of your muscles, decreasing muscle efficiency, and causing that awful burning sensation - that is why Xendurance's goal was to develop running supplements that are all-natural, drug free product, which would improve an runner's performance by improving both aerobic and lactate acid threshold. 

BUT Xendurance is now here to help with the best running supplement you can find - the Xendurance formula and physical chemistry of its 9 ingredients not only assures you that it will buffer production of H+ (Hydrogen ions) and help prevent the acid buildup in your muscles, but it has also been clinically proven to increase aerobic threshold so you can work harder for a longer period of time.

Research conducted in 2016 at the University of Louisiana at Lafayette examined the effects of 10 days Xendurance on performance, buffering capacity during exercise and post exercise muscle damage, oxidative stress and inflammation.

In this a double-blind, placebo controlled, crossover study with 16 active males that assessed the total effects of Xendurance during exercise.


  • 26% Reduction in Lactic Acid,
  • 39% Reduction in Oxidative Stress
  • 6x lowering of CK Levels.


1) Xendurance - for Performance / Recovery to reduce the effect of lactic acid.

2) Fuel 5- Quick & Sustained Energy from 5 forms of Fuel, carbohydrate and lactate.

3) Protein - Recover & Rebuild to support new lean muscle growth.

4) Hydro X - Hydration & Energy to prevent cramping.


Amazing product for muscle soreness and tiredness

"I've been using these for a few months now and really noticed the difference they make when I ran out of tablets last week and had to do a sportive and training without them for about a week. I used to always suffer with cramp - to the point that I would be in tears with pain at night, but nothing since I started using these. They really work and I will make sure not to run out again"
