Athletes turn to FlyCarb BiCarrb when every second counts. With sodium bicarbonate to buffer muscle acidity and caffeinated options to fight fatigue, BiCarrb helps endurance athletes push harder, push longer, and recover faster.
If you’ve ever put in hard effort, whether in training or racing, you know about that "wall"...that familiar burn you bump up against that forces you to slow down. FlyCarb BiCarrb just launched three new flavors — including caffeinated options — designed to help you push harder, delay fatigue, and feel fresher on race day.
What's New:
Peach with Caffeine – Already a fan favorite. Clean peach flavor with 120mg of caffeine per serving.
Original with Caffeine – Straightforward flavor, same 120mg caffeine boost.
Mint – No caffeine. A refreshing option for race day.
How It Works:
During all-out efforts, your muscles produce hydrogen ions faster than your body can clear them. These ions make your muscles more acidic, which interferes with muscle contraction and forces you to slow down. Sodium bicarbonate increases your blood's buffering capacity—neutralizing hydrogen ions so you can maintain higher power output longer.
The caffeinated versions attack fatigue from two angles. Bicarbonate buffers the muscle burn. Caffeine sharpens your central nervous system—motor units fire harder, and hard efforts feel easier. One drink, dual mechanism, no extra timing.
The Benefits:
Push harder, longer. Sustain race pace deeper into efforts that used to break you.
Delay the burn. Buffer the buildup of hydrogen ions that acidify your muscles, so you can hold threshold longer.
Stomach-friendly formula. FlyCarb uses an energy gel base that wraps sodium bicarbonate in maltodextrin and fructose, helping protect your stomach. Way easier to tolerate than raw powder or capsules.
Weight-based dosing. Available in four precise portions (12g, 16g, 20g, 24g) matched to your body weight. No guesswork.
How to Take It:
Timing: Take 90 minutes to 2 hours before your race or hardest training session. For events longer than 90 minutes, you can reduce the timing to 60-90 minutes before the start. Have a light meal about 30 minutes before taking BiCarrb. Avoid consuming other nutrition or food 20 minutes before or after.
Preparation: Mix the Energy component with 60ml of water until smooth, then stir in the Bicarb component. Consume immediately—do not pre-mix hours in advance.
Frequency: Use a maximum of twice per week for your most important sessions or races. Stay well-hydrated and minimize other sodium intake on bicarb days. Why only a couple times per week? Sodium bicarbonate is powerful, but your stomach and digestive system can only handle so much at once. Using BiCarrb only a couple of times per week helps you get the performance benefits without overstressing your gut or running into GI discomfort.
Dosing by Body Weight:
Under 60 kg (under 132 lbs): 12g
60–80 kg (132–176 lbs): 16g
80–90 kg (176–198 lbs): 20g
Over 90 kg (198+ lbs): 24g
Proper dosing is critical. Too little may reduce buffering benefits, while too much can increase the risk of GI discomfort.
Pro tip: Test it in training before race day. Every athlete responds differently.
