näak Boost Energy Gels - One packet

Boost Gels are built for shorter, high-intensity efforts, with easy-to-digest carbs for quick energy. Ultra Gels are designed for long ultra-endurance events. They contain 2 g protein and 9 g fat, which slow digestion and provide more sustained, longer-lasting energy.

Boost Gels use a 2:1 glucose-to-fructose ratio (2g glucose for every 1g fructose). Using two sugars instead of one is intentional: glucose and fructose absorb through different pathways in your gut, so combining them lets your body take in carbs faster and helps reduce the stomach upset that can come from higher-intensity efforts.

For most people, yes, caffeine can give performance a boost. But some people are genetically slower caffeine metabolizers, and for this group caffeine may not help, and can sometimes hinder, performance. The best way to know where you land is to trial caffeine in training before race day, never for the first time on race day.

It can help you feel cooler, even if it doesn't lower your actual body temperature. Mint's cooling sensation comes from menthol, which triggers cold receptors in your mouth. Studies show menthol mouth rinses can improve perceived thermal comfort and, in some cases, boost performance in hot conditions. Most of this research tests menthol as a mouth rinse rather than swallowed, but since the cooling sensation happens on contact with your mouth, the same perceptual benefit should carry over to a gel. So while mint won't cool your core, it can make hot efforts feel more manageable.
