GU Energy Labs

GU Energy Labs nutrition and supplement products give you all the juice you need for your training—no matter how far you go.

Nutritionists pack each GU product with just the right amounts of essential nutrients to keep you at the top of your game. Easily digestible carbs will help keep you from bonking in the middle of a race, while amino acids can jump start your recovery.

Fine tune your race-day strategy with a GU Energy Gel or top off your tank with a pre-training GU Stroopwafel. With energy gels, snacks, drink mixes and more, GU Energy has the nutrition products you need to fuel up before a workout and recover after.
