Powerbank Nutrition BiCarb ARC

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
