Bserk Core Fat Burner Supplement Facts

Core x3 Trial Packs

We are profoundly passionate about fitness. It’s a force that’s driven and inspired us from day one. So we’ve set out to make it better. To bring you a better product, one that combines our experience to help drive the level of your training. To give you the focus, mindset, and needs to get the most out of your workout. Developed by world's top trainers, to serve one passion we both share in common—fitness.

We've teamed up with Rob Riches—A world class fitness model and professional competitor to help us develop the product. And we created Core with the same sense of mindset. We didn't want to sell just a product, but rather sell the experience that comes with the product. Core is a natural and safe fat burner that includes a unique blend of over 12 synergistic, botanic and performance-driven ingredients that help increase the focus and intensity of your workout. We've also included a potent fat metabolizing formula to help breakdown the body fat and uses it as energy after you burn out to ensure you're giving your training the absolute best.
We believe that being comfortable is essential for creating a fat burner product that delivers a good workout experience. But we've also wanted to add the right sum of energy to fuel you through your workout and make the feeling noticeable.
The moment after you take Core, the combination of the 12 plant-based, active-ingredients will start to bring everything into focus. You'll feel the vibrant details of your surroundings from grabbing the barbell, dropping the weights to running or doing any other physical activity. You will feel the rich music notes leaping off your headphones straight to your head to deliver a bold, and even visual training experience effortlessly.
Core has been engineered from the ground up to deliver a comfortable, efficient performance that leaves you without any crashing or jittery feeling after. We didn't want to take what's out there and improvise, but rather we started from a plain sheet of paper. Instead of asking 'What can the product do?" We asked, "What do we want the product to be able to do?"


We integrated the natural power of over 12 botanical ingredients to increase the breakdown of body fat, to give you the drive and liveliness to commit to every bit of your training from start to end.


We recommend you start by taking half a serving (2 capsules), 20-40 minutes prior to training. Once your tolerance has been assessed, you may take a full serving prior to training.
Each serving of Core consists of 4 vegan-capsules. This may sound like a lot at first but remember that this is more than just a Pre-Workout product. It also includes a fat metabolizing formula, so it's like 3 products in 1. 



The most effective time to take a Core is 20-40 minutes before training or any physical activity/sport.

For best weight loss results, take one serving of Core 20-40 min prior to cardio, on empty stomach after not having eaten for at least an hour. This is so that the body has a greater preference towards body fat as fuel, and so the ingredients can work best. For best results, perform cardio in the morning before eating and take 1 serving with an additional 16 oz of water, to stay hydrated during exercise. 


Due to the natural formulation of CORE, you can use it daily. Although due to the body's tendency to adapt to external stimuli, we recommend taking 1-2 days off each week so that the effects remain strong. Unlike many other products marketed towards weight loss, this doesn't effect your adrenal glands. Instead, it works alongside the natural processes of fat burning for fuel within your body - just encouraging more of it.


We recommend to not exceed 2 servings per day. If your workout schedule requires two workouts, we recommend to only use one serving of Core per workout. Make sure to have a 6-8 hour gap in between the consumption. And since Core includes caffeine from Green Coffee Extract, we recommend to prevent consuming any stimulants like coffee, energy drinks or tea if you decide to take more than one serving/day.


Core contains 300mg of caffeine mainly from Green Coffee Extract, Caffeine Anhydride, and TeaCrine®.
