    L-Arginine for Wound Healing

    Arginine shows benefit in pressure ulcers as part of combined nutritional formulas.

    Overview

    Arginine shows benefit in pressure ulcers as part of combined nutritional formulas.

    Verdict

    Insufficient evidence

    How It Works

    Precursor to nitric oxide and proline, supporting perfusion and collagen deposition.

    Dosing & Protocol

    Typical dose

    Recommended dose
    4.5-9g/day within a nutritional formula
    Expected timeframe
    8-12 weeks

    Protocol

    measurement
    Wound surface area and PUSH score every 1-2 weeks
    studied dose
    4.5-9 g/day arginine within a complete oral nutritional supplement, in pressure ulcer trials
    evidence note
    Verdict is insufficient - benefit cannot be separated from the protein and calories delivered alongside it
    what happened
    Pressure ulcer healing improved, but the formulas also supplied extra protein, energy, zinc and vitamin C, so arginine's independent contribution is unknown
    if you still use it
    Use the whole nutritional formula as studied, twice daily between meals, alongside standard wound care and dietitian input - not isolated arginine powder

    Evidence

    What the studies say

    Trials of arginine-containing oral nutritional supplements show improved pressure ulcer healing, though the contribution of arginine alone cannot be separated from added protein and energy.

    No studies are yet linked to both L-Arginine and Wound Healing.

    Safety

    Caveats

    Effects confounded by the protein and calories in the same formulas. Caution after myocardial infarction.

    Less likely to help if

    People with adequate protein intake and no nutritional deficit, and those whose wounds are limited by ischaemia, infection or continued pressure.
