BootBurn STRONG ACTIVE 1000 now has an even more powerful formula than our previous fat burners: it contains double the amount of L-carnitine, green tea and mate tea.


  • Green tea, mate tea and guarana are well-known thermo burners, which make the body speed up fat burning to produce more heat.
  • L-carnitine is essential for burning fat and producing energy. It is like a public transport system that carries most of the fat we consume (long-chain fatty acids) to the fat-burning core of our cells, the mitochondria. Without L-carnitine, we could not burn fat or get energy from it!
  • Combined with B-complex, without which we could not transform food into energy, BootBurn STRONG ACTIVE 1000 has even more functionality: it raises energy levels, prevents fatigue and increases performance.


“I had never had problems with excess weight before. I had always been very physically active. However due to health problems, I was forced to give up extreme physical activities, so the pounds starting to pile on. I no longer felt comfortable in my skin and I lacked energy. BootBurn STRONG ACTIVE 1000 saved me! After a long time, I could finally do sport without any problems and I immediately noticed how more effective my workouts became. Now my body is more toned and I feel good about myself again - when I look in the mirror in the morning, I am proud of my transformation and the days seem much brighter!”
