Product Overview
GU Original Energy Gel is a compact sports-fuel packet built around carbohydrates, sodium and amino acids. It is intended for convenient fueling during sustained activity rather than as a replacement for everyday meals or hydration. Each packet contains 100 calories and 21–23 g of carbohydrate, while sodium and caffeine vary by flavor. MotionLab offers single gels and multi-pack formats in selected flavors.
Construction & Technology
Dual-source carbohydrate blend
Maltodextrin and fructose provide two carbohydrate sources in one packet. Each flavor supplies 21–23 g of carbohydrate and 100 calories.
Flavor-specific sodium content
Each packet contains 60–125 mg of sodium depending on flavor. GU advises taking the gel with water rather than treating it as a complete hydration solution.
Amino-acid blend
The formula includes 450 mg of amino acids per packet alongside carbohydrates and electrolytes.
Caffeinated and caffeine-free options
Caffeine is not the same across all flavors. Check the exact packet before use, especially when combining gels with coffee, sports drinks or other caffeinated products.

Finally found a store that actually understands runners.
I was dealing with knee pain for months — every other store tried selling me random shoes. Motion Lab actually asked about my pace, surface and training plan. They recommended the Brooks Ghost and it completely changed my runs. Zero pain now.

Delivered in 24 hours — literally saved my race weekend.
I ordered On Cloudmonster 2 the day before a 10K race, expecting it to arrive after the event. Not only did it arrive the next morning, they even WhatsApp’d me with tips for breaking them in safely. Unreal service.

The only store in Israel that actually stocks the latest Hoka releases.
I’ve been waiting months for the Hoka Mach X — every big chain still didn’t have it. Motion Lab had it first, in my size, and even let me exchange after one run when I wasn’t sure about the fit. Customer service at another level.
