Rayo energy gels deliver steady, usable energy without the crash or the stomach trouble most gels cause. Each Cucumber Lime gel packs 24g of dual-carb fuel, 65mg of sodium for hydration, and 325mg of amino acids to support muscle performance, all in a smooth gel that's easy to get down mid-effort. Taken one every 30 minutes, they help you hold your energy and pace from start to finish.

Rayo stands apart on flavor and formula. Most gels are bland, artificial, or hard on your stomach, while Rayo leads with bold, real flavors and a 2:1 glucose-to-fructose dual-carb blend that uses two absorption pathways to deliver more energy at once without overloading your gut. You also get more gels per box at a lower price per serving than most major brands.

Cucumber Lime is built on maltodextrin and fructose for dual-carb fuel, BCAAs (leucine, isoleucine, valine) for muscle support, sodium citrate for hydration, and chromium picolinate plus vitamin B12 for energy metabolism, finished with natural cucumber and lime extracts. It's free from GMOs, gluten, dairy, and soy. Horchata is made with real almond butter, natural caffeine, and cinnamon, with zero added sugar.

Rayo is designed to provide effective carbohydrate and caffeine fueling in a smooth, easy-to-consume format. As with any endurance fuel, individual tolerance varies, so we recommend testing Rayo during training before using it in competition.

Cucumber Lime was created to give athletes a more light, crisp, refreshing flavor instead of the overly sweet or artificial taste commonly associated with energy gels. We use natural cucumber and lime extracts to create a recognizable flavor that works especially well during longer efforts. Cucumber Lime is intentionally formulated to be refreshing rather than overwhelmingly sweet. Our customers frequently highlight the light, crisp flavor and lack of a chemical aftertaste as some of their favorite things about the gel.

Take one gel about every 30 minutes during activity to keep your energy steady and avoid bonking. Start fueling early, before you feel depleted, rather than waiting for the crash.

It depends on the flavor. Cucumber Lime is caffeine-free, so you can use it any time of day without affecting sleep. Horchata contains 60mg of natural caffeine per gel for extra focus and energy, roughly the equivalent of half a cup of coffee.

Rayo is formulated to be gentle on the gut. The 2:1 glucose-to-fructose ratio lets your body absorb carbs through two pathways instead of overloading one, which is a common cause of the GI distress people get from high-carb gels. Many athletes who can't tolerate other gels find Rayo easier to take.

Rayo comes in two flavors. Cucumber Lime is a crisp, cooling everyday fuel with 24g of dual carbs, electrolytes, and amino acids. Horchata is a lighter, cinnamon-forward option with natural caffeine and zero added sugar for fast, clean energy. More flavors are on the way.

Cucumber Lime comes in a 15-pack for $39.99, about $2.67 per gel, or less with a first-order discount. That's more servings per box and a lower price per gel than most major gel brands. A sample pack is also available if you'd like to try it first.

Rayo gels go down smooth on their own, so water isn't required.

Cucumber Lime is free from GMOs, gluten, dairy, and soy. Horchata is made with almond butter, which is a tree nut, so it isn't suitable for anyone with a tree nut allergy.

Yes. Rayo is built for endurance efforts of all kinds, including running, cycling, lifting, and long training days. The dual-carb formula and steady 30-minute fueling rhythm suit anything from marathon training to long rides, and the gels are light and easy to carry.
