I’ve added a short appendix, Wound Healing in Vegans, to our Protein page.
Posso et al. (United States, 2025) conducted a review of studies examining the impact of wound healing in vegans and vegetarians. They found poorer wound healing in vegans.
In my opinion, the difference is likely due to lower protein intakes, and possibly zinc intakes, among vegans recovering from surgery.
Vegans with wounds should pay particular attention to obtaining ample amounts of protein and may want to consider taking a zinc supplement of approximately the RDA (11 mg for men, 8 mg for women), in addition to obtaining the typical nutrients of concern in vegan diets (see Nutrition Tips for Vegans).
