Sodium Bicarbonate

MODERATE EVIDENCESupplementLast updated

AVELOR SUMMARY

Sodium bicarbonate is one of the most evidence-backed ergogenic aids in sports nutrition — a meta-analysis of 40 studies confirmed it improves high-intensity exercise performance by 2.9%. It works by buffering blood pH, allowing muscles to tolerate more lactic acid before fatigue. Our research confirms the performance benefit is real and reproducible, but the GI side effects (nausea, bloating, diarrhea) affect 30-60% of users and are the primary barrier to practical use. Serial loading protocols (smaller doses over days) significantly reduce GI distress while maintaining the ergogenic effect.

WHAT IT DOES

High-intensity exercise produces hydrogen ions (H+) that lower muscle pH — the "burn" of lactic acid. When muscle pH drops below ~6.8, enzyme function is impaired and muscle contraction weakens. Sodium bicarbonate (NaHCO₃) acts as an extracellular buffer: it neutralizes H+ ions in the blood, creating a steeper concentration gradient for H+ to leave the muscle cells. This means muscles can produce more acid before reaching the performance-limiting pH threshold. The 2-3% improvement translates to meaningful time savings in competition (e.g., 1-2 seconds in a 400m sprint).

OPTIMAL DOSAGE

Look for: Pharmaceutical-grade sodium bicarbonate; enteric-coated capsules (reduce GI distress); capsule form for precise dosing
Avoid: Random grocery store baking soda for sport performance (imprecise dosing, severe GI effects); effervescent tablets with added sweeteners
Minimum effective dose: 0.2g/kg body weight (14g for 70kg person)
Third-party tested brands: SiS (Go Hydro), Maurten (sodium bicarbonate system), bulk pharmaceutical-grade NaHCO₃ in capsules
