Overview
What does the SiS Beta Fuel + Nootropics Gel do that other gels don't?
The SiS Beta Fuel + Nootropics Gel combines 40g of dual-source carbohydrates in the 1:0.8 maltodextrin-to-fructose ratio with a cognitive performance stack: 200mg of caffeine, 200mg of L-theanine, 250mg of Cognizin Citicoline, and 1g of L-taurine. The result is a gel that fuels both your muscles and your mind simultaneously. The caffeine provides the physical and mental boost, L-theanine reduces the jittery edge that caffeine alone can cause, and Cognizin Citicoline is a clinically studied nootropic compound shown to support information processing and mental focus. Science in Sport designed this gel for the latter stages of long endurance efforts when cognitive performance and decision-making start to decline alongside physical fatigue.
Due to the high caffeine content (200mg per gel), the maximum dosage is one gel per day. Consume it approximately 60 minutes before you want to benefit from the cognitive effect, ideally in the final phase of your event. The physical carbohydrate delivery works identically to the standard Beta Fuel Gel: isotonic, no water required. Available in Apple and Lemon and Lime. Informed Sport certified, every batch independently tested against the WADA banned substances list.

FAQ
Good questions
Get to know Science in Sport

There's more to Science in Sport than this one product. Our Science in Sport page has the full Science in Sport lineup we carry and more about the brand.
Visit the Science in Sport page →What are nootropics and why are they in this gel?
Nootropics are compounds that can enhance cognitive function. In this gel, 200mg caffeine, 200mg L-theanine (which reduces caffeine-induced jitteriness), and 250mg Cognizin Citicoline are combined to sharpen focus, improve information processing, and maintain decision-making quality during the late stages of endurance events when the brain, like the body, starts to fatigue.
Is there a usage limit on the Beta Fuel + Nootropics Gel?
Yes. Maximum one serving per day due to the 200mg caffeine content. Do not combine with other caffeine sources on the same day without accounting for total caffeine intake.
When should I take the Beta Fuel + Nootropics Gel during a race?
Consume it approximately 60 minutes before you want to benefit from the cognitive effect. This is typically during the latter stages of a long race or training effort.
Does this gel need to be taken with water?
Like all Beta Fuel gels, this product is isotonic and can be consumed without additional water.
