NaHCO3 (Baking Soda)Extracellular pH BufferPerformance Supplement (60-180 sec efforts)Dietary Supplement

Sodium Bicarbonate (NaHCO3, baking soda) is one of the most-studied performance supplements - alkalizing agent that buffers exercise-induced acidosis in 60-180 second efforts. Mechanism distinct from beta-alanine (intramuscular carnosine) - bicarbonate works extracellularly to buffer hydrogen ions diffusing out of muscle cells.

How it works

Sodium Bicarbonate buffers extracellular pH:

Bicarbonate Buffer

HCO3- combines with H+ ions diffusing out of muscle cells to form carbonic acid → CO2 + water (exhaled). Net effect: extracellular pH stays higher.

Time-Domain Specific

Most effective for 60-180 second efforts where lactic acidosis is rate-limiting. Less effective for shorter sprints (<30 sec) or longer endurance (>10 min).

Distinct from Beta-Alanine

Beta-Alanine raises intramuscular carnosine for INTRACELLULAR buffering; bicarbonate works extracellularly. Often combined for additive effect.

Acute Mechanism

Single-dose loading 60-90 min pre-event. Some users adopt chronic loading protocols (multiple smaller doses over days) to reduce acute GI burden.

Sodium Load

Performance dose (~21g) contains ~5.7g sodium - significant for users on sodium restriction.

What to expect

Early

Days 1–7

60-90 min onset for performance.

Mid

Weeks 2–4

Performance window 1-3 hours.

Later

Weeks 4–12

Chronic loading: cumulative buffering over days.
