Recommended Usage

We suggest you start by taking half a serving (2 capsules), 20-40 minutes before 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 and fat burning formula, so it's 3 products in 1. 

Frequently Asked Questions (FAQ)

When Should You Take Core?

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 before cardio, on an 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.

How long should you take Core for?

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 affect your adrenal glands. Instead, it works alongside the natural processes of fat burning for fuel within your body - just encouraging more of it.


How many servings of Core can I take per day?

We recommend not to exceed 2 servings per day. If your workout schedule requires two workouts, we recommend only to 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 preventing consuming any stimulants like coffee, energy drinks or tea if you decide to take more than one serving/day.

How much caffeine does Core have per serving?

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