Product Description
You've heard about sodium bicarbonate. Maybe you've even tried it — and spent half your race paying for it. The bloating, the belching, the cramping that shows up at exactly the wrong moment. That's not your body just rejecting bicarb, that's the delivery system failing you.
Sodium bicarbonate is one of the most proven legal performance tools in endurance sport — the International Olympic Committee recognizes it as an effective ergogenic aid. The biochemistry is clear: it neutralizes the hydrogen ions that build up in your blood during hard efforts, pushing back the point where your muscles force you to slow down. The problem has never been the molecule. It's always been getting it to where it needs to go.
Powerbank Nutrition BiCarb ARC solves that problem at the hardware level.
Acid-Resistant Capsule Technology – This changes everything. ARC stands for Acid Resistant Capsule. The capsule is chemically engineered to survive your stomach's acidic environment completely intact, bypassing it entirely and releasing the bicarbonate in your small intestine — the optimal site for clean, efficient absorption. No CO₂ gas reaction in your gut. No bloating. No taste. No GI interference.
25% Lower Dose Required – When bicarb reacts in your stomach, a significant portion of the active compound is wasted before it ever reaches your bloodstream. You compensate by taking more, which compounds the GI risk. Clinical data confirms that intestinal delivery is measurably more efficient. BiCarb ARC reaches the same performance-critical blood saturation level — 5 mmol/L — with 25% less total bicarbonate load. You get there with less, and you get there clean.
Same Bicarb Benefits, Easier to Take – Traditional bicarb formats ask you to trade GI comfort for performance. BiCarb ARC doesn't make you choose. The capsule format is tasteless, convenient, and titratable — you dial in your dose based on body weight using the 1000mg/10 lbs protocol, round up or down based on your GI sensitivity, and take it 90–120 minutes before your performance window.
How to Use Powerbank Nutrition BiCarb ARC
Dose: Take 1,000mg per 10 lbs of body weight. Round up to the nearest 1,000mg capsule to maximize buffering; round down to minimize any potential GI sensitivity.
Timing: Consume 90–120 minutes before your target performance window — intervals, race-pace efforts, or the final hard block of a long race.
Pro Tip: Test your dose in training before race day. Start at the lower end of your weight-based dose and build up across sessions to dial in your personal sweet spot.
If your buffering protocol has been leaving you doubled over at mile three, the issue was never bicarb itself. BiCarb ARC delivers the same proven buffer — cleaner, lower, and without the interference that derails direct-dose products when it matters most.
BiCarb ARC Dosing Guide
Formula: 1,000 mg per 10 lb body weight, rounded up to the nearest capsule.
| Body Weight | Dose Range |
|---|---|
| 100 – 129 lb | 10 – 13 capsules |
| 130 – 159 lb | 13 – 16 capsules |
| 160 – 189 lb | 16 – 19 capsules |
| 190 – 219 lb | 19 – 22 capsules |
| 220 lb + | 22+ capsules |
|
Find your exact dose: divide your weight (lb) by 10, then round up to the nearest whole capsule. Example: 143 lb ÷ 10 = 14.3 → round up to 15 capsules (15,000 mg). Take 90–120 minutes before your target performance window. New to BiCarb ARC? Start at the lower end of your range and build up across sessions. |

Powerbank Nutrition BiCarb ARC FAQ's
Everything you need to know about Powerbank Nutrition BiCarb ARC.
Sodium bicarbonate acts as a blood buffer — it neutralizes the hydrogen ions that accumulate during high-intensity efforts and cause the burning sensation that forces you to slow down. By keeping blood pH higher for longer, it pushes back the point at which your muscles hit their ceiling. The IOC and ISSN both recognize it as one of the few supplements with consistent evidence of improving high-intensity performance.
Because the delivery method fails them, not the molecule. Traditional bicarb formats react with stomach acid to produce CO₂ gas, causing bloating, belching, and cramping — often timed perfectly to coincide with the start of a race. BiCarb ARC's acid-resistant capsule bypasses the stomach entirely, releasing only in the small intestine where absorption is efficient and gas production doesn't happen.
ARC stands for Acid Resistant Capsule. The capsule is chemically engineered to remain intact through the stomach's acidic environment and dissolve only in the small intestine — the optimal site for bicarbonate absorption. This isn't an enteric coating applied after the fact; it's the capsule material itself that provides the resistance.
When bicarb breaks down in the stomach, a significant portion reacts before it ever reaches the bloodstream — wasting active compound and creating GI side effects in the process. Intestinal delivery bypasses that reaction entirely, meaning more of what you take actually reaches your blood. Clinical data confirms this efficiency difference, which is why BiCarb ARC achieves the same performance-critical blood bicarbonate level with a meaningfully lower total dose.
The protocol is 1,000mg per 10 lbs of body weight. Round up to the nearest 1,000mg to maximize buffering, or round down if you're more GI-sensitive. A 150lb athlete would take 15,000mg (15 capsules); a 180lb athlete would take 18,000mg (18 capsules). If you're new to bicarb, start at the lower end and build across training sessions to find your personal threshold before using on race day.
Consume your dose 90 to 120 minutes before your target performance window — intervals, race-pace efforts, or the hard final block of a long race. This timing accounts for the capsule passing through the stomach and bicarbonate being absorbed into the bloodstream. Unlike traditional bicarb which peaks unpredictably, the controlled intestinal release makes that timing window more reliable.
