    L-Citrulline for Sprint Performance

    Citrulline is better supported for volume work than for sprint speed.

    Overview

    Citrulline is better supported for volume work than for sprint speed.

    Verdict

    Insufficient evidence

    How It Works

    Raises plasma arginine and nitric oxide, improving blood flow and ammonia clearance.

    Dosing & Protocol

    Typical dose

    Recommended dose
    6-8 g citrulline malate pre-exercise (studied dose)
    Expected timeframe
    Assessed acutely

    Protocol

    dose
    6-8 g citrulline malate
    form
    Citrulline malate 2:1
    timing
    Pre-exercise
    duration
    Assessed acutely

    Evidence

    What the studies say

    Trials show improved resistance training repetitions and reduced soreness. Sprint-specific improvements are inconsistent and generally small.

    No studies are yet linked to both L-Citrulline and Sprint Performance.

    Safety

    Caveats

    INSUFFICIENT verdict — a few small sprint/repeated-sprint trials with inconsistent findings; no reliable benefit demonstrated. Nitrate/PDE5 interaction applies.

    Less likely to help if

    Unknown — too little data
