Product Description
You know the feeling. You're 45 minutes into a race, pace is slipping, and you reach for a caffeine gel. Then you spend the next 20 minutes waiting for it to kick in. By the time it does, the damage is already done. Here's what most athletes don't realize: the format you use to take caffeine matters just as much as the dose. A gel or capsule has to clear your stomach and your liver before it reaches your brain. That takes 30 to 45 minutes. You don't always have 30 to 45 minutes.
SiS Caffeine Gum puts 100mg of caffeine in each piece and delivers it in 15 minutes, absorbed directly through the mouth and esophagus, bypassing the digestive system entirely. It's the fastest caffeine format available for athletes who need to time their boost precisely.
Faster Than Any Gel, Shot, or Drink
Research shows that around 85% of the caffeine in gum is absorbed within 5 to 15 minutes of chewing, compared to 20 to 45 minutes for capsules and drinks. That changes how you use caffeine entirely. Instead of pre-loading and hoping the timing works out, you chew with precision, exactly when you need it.
100mg Per Piece, Sugar-Free, Pocket-Ready
Each piece delivers a precise 100mg hit, the equivalent of a strong coffee, with no sugar, no liquid to carry, and no prep. Two pieces fit in a jersey pocket, a race kit, a shoe bag. It's the most compact caffeine delivery system available, and it works on the start line, mid-race, or the final push when you need to switch back on.
Batch Tested and Informed Sport Certified
Every batch is independently tested for all compounds on the WADA Banned Substances list through the Informed Sport program. Clean for drug-tested athletes at every level, from age groupers to professionals.
Caffeine works by blocking adenosine, the compound that builds up in your brain during sustained effort and creates the perception of fatigue. With adenosine blocked, your brain stays sharper, your perceived effort drops, and your reaction time stays quick. Decades of research back caffeine as one of the most consistently effective performance ingredients in sport, shown to improve endurance performance, sprint output, strength, agility, and cognitive function. The gum format adds one more advantage: because it bypasses the stomach, it's lighter on the gut than gels or drinks during high-intensity efforts, when GI distress is most likely to strike. SiS also added Vitamins B3, B6, and B12 at 15% of the recommended daily value per piece, supporting the neurotransmitter activity that keeps your focus sharp across long efforts.
Before your session: Chew one piece 15 minutes before the start. By the time you hit race intensity, it's already working.
Mid-race or late in a long effort: Chew one piece 15 minutes before you need the effect. For a 10K, that's around the 4K mark. For a long ride, that's the final climb. You control the timing in a way you never could with a gel.
Max dose: Up to two pieces can be taken at the same time. Do not exceed four pieces in a day.
Pro tip: If you're caffeine-sensitive or new to caffeine gum, start with one piece in training before using two on race day. The faster absorption means you'll feel it sooner than you're used to.
SiS Caffeine Gum has been studied specifically in team sport and endurance contexts, with research showing performance benefits for cyclists, runners, football players, and rugby athletes. It's trusted by professional athletes across disciplines who need caffeine timing they can actually control.
This isn't just another caffeine product. This is the fastest, most precise caffeine format available: two pieces in your pocket, 15 minutes to peak, and no GI gamble on race day.
What Is SiS Caffeine Gum?
SiS Caffeine Gum is a sugar-free, peppermint-flavored caffeine gum built specifically for athletes. Each pack contains 10 pieces at 100mg of caffeine each, with Vitamins B3, B6, and B12 to support energy metabolism and cognitive function. It's the same caffeine format trusted by professional cyclists, runners, and team sport athletes who have figured out that timing precision matters as much as dose. Now it's available at The Feed.
I've watched a lot of athletes time their caffeine wrong. They take a gel too late, or front-load so much before the start that they're crashing at exactly the wrong moment. What I like about the SiS gum is that it gives you actual control. You chew it when you need it, it kicks in 15 minutes later, and you can carry ten pieces in the same space as one gel packet. That's a different tool than anything else we carry. Once you understand the timing, it changes how you think about caffeine on race day entirely.

SiS Caffeine Gum FAQ's
Everything you need to know about SiS Caffeine Gum.
When you chew caffeine gum, the caffeine is absorbed directly through the mucous membranes in your mouth and esophagus before it ever reaches the stomach. This bypasses the digestive system and liver entirely, which is the bottleneck that slows absorption from gels, capsules, and drinks. Research shows around 85% of the caffeine in gum is absorbed within 5 to 15 minutes, compared to 20 to 45 minutes for traditional formats. For athletes who need to time their caffeine precisely, that difference is significant.
Each piece contains 100mg of caffeine, equivalent to a strong cup of coffee. Up to two pieces can be taken at the same time for a 200mg dose. Do not exceed four pieces in a single day. If you're new to caffeine supplementation or sensitive to caffeine, start with one piece in training to understand how your body responds before using two pieces on race day.
Chew one piece 15 minutes before you want the effect. Before a race or hard session, that means chewing at the start line or during your warm-up. During a race or long effort, chew 15 minutes before the point where you need the boost: the final climb, the last interval, the turn into a headwind. Because the onset is so fast, you can use caffeine reactively during a race in a way that gels don't allow. The precision is the point.
Yes. SiS Caffeine Gum is Informed Sport certified, meaning every batch is independently tested for all compounds on the WADA Banned Substances list by LGC Assure, an accredited laboratory that has been testing for banned substances for over 20 years. Caffeine itself was removed from the WADA prohibited list in 2004 and is safe for competition at all levels.
Caffeinated gels typically contain between 25mg and 100mg of caffeine alongside carbohydrates, and they're absorbed through the digestive system over 20 to 45 minutes. SiS Caffeine Gum contains no carbohydrates and absorbs in 5 to 15 minutes. They serve different purposes: gels deliver carbs and caffeine together as an on-course fuel source. Caffeine gum delivers a precise, fast-acting caffeine hit without the carb load. It's useful when you need the cognitive and performance effect without adding to your carbohydrate intake, or when timing precision matters more than convenience.
