    Beta-Alanine for VO2 Max Improvement

    Beta-alanine improves high-intensity endurance without raising maximal oxygen uptake.

    Overview

    Beta-alanine improves high-intensity endurance without raising maximal oxygen uptake.

    Verdict

    Insufficient evidence

    How It Works

    Increases muscle carnosine, buffering hydrogen ions during glycolytic work.

    Dosing & Protocol

    Typical dose

    Recommended dose
    3.2-6.4g/day in divided doses
    Expected timeframe
    4-10 weeks

    Protocol

    studied dose
    3.2-6.4 g/day in divided doses for 4+ weeks
    evidence note
    Verdict is insufficient - VO2 max itself does not change
    what happened
    Meta-analyses show performance gains in 1-4 minute efforts, but measured VO2 max is unchanged. What improves is the ability to sustain intensity at or near VO2 max, which is a different variable
    if you still trial it
    3.2-6.4 g/day split into 1.6 g doses for 4+ weeks, judged on time-to-exhaustion at VO2 max pace rather than on the VO2 number
    what actually raises VO2 max
    High-intensity interval training and increased training volume - no supplement moves this meaningfully

    Evidence

    What the studies say

    Meta-analyses show performance gains in 1-4 minute efforts. VO2 max itself is unchanged; the benefit is in sustaining intensity.

    No studies are yet linked to both Beta-Alanine and VO2 Max Improvement.

    Safety

    Caveats

    Harmless paraesthesia is common. Does not change maximal oxygen uptake.

    Less likely to help if

    Anyone judging the effect on a VO2 max value, and untrained people whose training will move it far more.
