Product Description
Your legs go rubbery the minute you need to hold on. Maybe that's an 800m repeat, the final kick of a crit race, or the last interval on a track workout. Lactic acid is piling up in your muscles faster than your body can flush it out, and that's the burn that shuts your legs down. Buffer that acid and you buy yourself more time at your best pace before it wins over you.
Carbs Fuel Bicarb delivers that extra time, packing a full and flexible dose of sodium bicarbonate into enteric capsules built to bypass your stomach and land intact in your small intestine.
Removes GI Issues - The capsules resist stomach acid and hold together until they reach your small intestine, cutting the bloating and cramping that scares athletes off bicarb all together.
Dosed to Your Body Weight - Every bag comes pre-portioned at 15g, 20g, or 25g per pouch, matched to a 0.2-0.4 g/kg range relative to body weight. Start low and build toward the higher end over a few sessions before race day.
15g: New to bicarb supplementation and/or athletes 50kg-70kg in body weight
20g: Intermediate bicarb users and/or athletes 60kg - 90kg
25g: Advanced bicarb users and/or athletes 70kg - 110kg
No Mixing, No Mess, No Excuses - Skip the bowl of chalky powder. Grab a pre-measured pouch and water, good for a trainer session or a race-day bag.
During an all-out effort, your muscles produce hydrogen ions faster than your bloodstream can buffer them, and that rising acidity forces you to slow down early. Sodium bicarbonate raises your blood's buffering capacity to absorb more of that acid, which is why loading it ahead of a hard effort lets you hold pace deeper into the red. Raw bicarbonate reacts almost immediately in the stomach, causing the gas and bloating that made athletes give up on it, while the enteric coating lets it pass through intact and release where your body can use it.
How to Use Carbs Fuel Bicarb
Dose: Take one full pouch (15g, 20g, or 25g depending on your body weight and bicarb history) with a full glass of water.
Timing: Take it 90 to 120 minutes before your hardest efforts, and fast for the hour before so the capsules move through unimpeded.
Building Your Dose: New to bicarb? Start at 0.2 g/kg and build toward 0.4 g/kg over a few sessions before race day. This formula carries a considerable sodium load, so track your fluids and total sodium intake.

Carbs Fuel Bicarb FAQ's
Everything you need to know before getting started.
Take a full pouch with water 90 to 120 minutes before your hardest efforts, and fast for the hour before you take it so the capsules move through your stomach without food in the way.
Dosing runs 0.2 to 0.4 grams of bicarb per kilogram of body weight. Start at 0.2 g/kg and build up toward 0.4 g/kg over a few training sessions before using it for a race.
The enteric capsules are designed to resist your stomach's acid and dissolve in the small intestine instead, which is meant to reduce the GI distress associated with traditional bicarb supplementation.
Sodium bicarbonate helps buffer the acid your muscles produce during high-intensity effort, which is part of what limits how long you can sustain a hard pace.
The 15g pouch fits athletes newer to bicarb or in the 50–70kg range, 20g fits intermediate users around 60–90kg, and 25g fits advanced users around 70–110kg. Use your body weight and bicarb experience to pick your size.
It's built for high-intensity, repeated-effort work like intervals, races, and time trials where acid buildup is the limiting factor, rather than steady, lower-intensity endurance sessions.
