    Vasireddi 2025 anchors the most relevant signal. BPC-157 fits wound healing when the target is tissue repair, vascular recruitment, or inflammation control, but the case still rests mostly on preclinical models. The…

  2. Red Light Therapy

    8.0–8.5 /10 for wound healing 7.5–8.0/10 overall Strong recommend Light Therapy

    Hamblin 2017 summarizes angiogenesis, collagen, and inflammatory pathways that make photobiomodulation biologically credible. The evidence is strongest for selected superficial wounds and clinical protocols, not every burn or surgical scenario. Pradal 2025…

  3. GHK-Cu

    8.0–8.5 /10 for wound healing 7.0–7.5/10 overall Strong recommend Cosmetic & Dermatologic Peptide

    Pickart et al. 2015 supports the core mechanism. GHK-Cu keeps an 8 because topical wound evidence is clinically meaningful, especially Mulder 1994, where diabetic plantar ulcers had 98.5% median area closure versus…

  4. Hyperbaric Oxygen Therapy

    7.5–8.0 /10 for wound healing 5.5–6.0/10 overall Worth trying Hyperbaric

    Hyperbaric Oxygen Therapy is most often evaluated as an adjunct to standard wound care, where it appears to increase oxygen delivery to hypoxic tissue and support fibroblast activity. The evidence tier remains…

  5. TB-500 (Thymosin Beta-4 Fragment)

    7.5–8.0 /10 for wound healing 7.5–8.0/10 overall Strong recommend Growth & Repair Peptide

    Full-length Tbeta4 has credible wound and corneal-healing evidence: Dunn 2010 reported compassionate-use corneal healing, and Sosne 2023 found 6 of 10 RGN-259 subjects healed versus 1 of 8 placebo, a trend that…

  6. Ozone Therapy

    7.0–7.5 /10 for wound healing 5.0–5.5/10 overall Neutral Ozone & Oxidative Therapy

    Maglia 2024 reports Verified audit Track 1 source; 12 clinical studies, oral-ulcer size and pain reduction versus placebo, limited evidence quality. Lima 2024 points in the same direction, but route, dose, baseline…

  7. Essential Amino Acids

    7.0–7.5 /10 for wound healing 7.5–8.0/10 overall Strong recommend Amino Acid

    Hagiyama 2024 reports 12 RCTs; 622 patients; low-certainty improvement in patient-reported outcomes and very-low-certainty strength signal after lower-limb surgeries. Wittholz 2024 points in the same direction, but route, dose, baseline status, and…

  8. Glycine

    7.0–7.5 /10 for wound healing 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Holecek 2025 anchors the most relevant signal. Glycine fits wound healing because glycine participates in sleep signaling, glutathione, collagen, methylation, and nervous-system balance, depending on the endpoint. The score stays bounded because…

  9. PEMF (Pulsed Electromagnetic Field Therapy)

    6.5–7.0 /10 for wound healing 7.5–8.0/10 overall Strong recommend PEMF

    Postoperative wound and edema data support a moderate wound-healing rating. Stocchero 2015 found fewer healing complications after third molar extraction, while Rohde 2015 found reduced wound exudate and inflammation after breast reconstruction.…

  10. Molecular Hydrogen

    6.0–6.5 /10 for wound healing 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Dhillon 2024 reports 25-article systematic review; mixed preliminary clinical evidence, heterogeneity, and need for stronger trials. Zhou 2024 points in the same direction, but route, dose, baseline status, and outcome tracking decide…

  11. Vitamin C (Ascorbic Acid)

    6.0–6.5 /10 for wound healing 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Collagen deposition is the structural backbone of healing tissue, and vitamin C is the obligatory cofactor for the hydroxylase enzymes that stabilize collagen, so deficiency directly impairs wound closure and reopens healed…

  12. Lactoferrin

    5.5–6.0 /10 for wound healing 7.0–7.5/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Berthon et al. 2022 gives the strongest anchor. Wound-healing remains modest because lactoferrin has immune and antimicrobial mechanisms, but oral supplement RCTs for wound closure are limited. The score reflects mechanistic support…

  13. Thymosin Alpha-1

    5.5–6.0 /10 for wound healing 7.0–7.5/10 overall Strong recommend Immune Peptide

    Wu 2025 anchors the most relevant signal. Thymosin Alpha-1 fits wound healing when immune modulation is medically relevant and monitored rather than casually guessed. The score stays bounded because the best evidence…

  14. Collagen Peptides

    5.0–5.5 /10 for wound healing 7.0–7.5/10 overall Strong recommend Amino Acid

    Collagen is central to wound matrix formation, and oral collagen has emerging support for surgical wound and scar quality. The evidence is smaller than skin, joint, and tendon endpoints. That makes Collagen…

  15. Whole-Body Vibration

    5.0–5.5 /10 for wound healing 7.0–7.5/10 overall Strong recommend Vibration & Mechanical Stimulation

    Whole-Body Vibration may improve peripheral circulation, which can support the early phases of tissue repair. However, randomized trials that directly measure wound closure rates are few and show inconsistent results. Anti-inflammatory effects…

  16. Metformin

    5.0–5.5 /10 for wound healing 6.5–7.0/10 overall Worth trying Metabolic & Glycemic Drug

    Metformin's primary action is lowering blood sugar, which can indirectly support wound-healing in people with diabetes by reducing hyperglycemia-driven inflammation. Direct trials of Metformin as a topical or systemic wound-healing agent in…

  17. Ca-AKG (Calcium Alpha-Ketoglutarate)

    5.0–5.5 /10 for wound healing 6.5–7.0/10 overall Worth trying Vitamin & Mineral & Nutrient

    Filip 2007 is the cleanest verified anchor for this report. The existing rationale points to this narrower claim: No direct consumer Ca-AKG wound-healing evidence. Burn-care OKG and AKG literature is adjacent, heterogeneous,…

  18. Thymosin Beta-4 (Tβ4)

    4.5–5.0 /10 for wound healing 7.0–7.5/10 overall Strong recommend Growth & Repair Peptide

    Wound healing is the most-tested human application for Tβ4 outside the eye, and the data are real but mixed. The RGN-137 topical gel Phase 2 program covered pressure ulcers, venous stasis ulcers,…

  19. Zone 2 Cardio

    4.5–5.0 /10 for wound healing 8.0–8.5/10 overall Strong recommend Cardiovascular

    Improved circulation and glucose control can support wound healing over time. This is an indirect support effect. People with diabetic ulcers, vascular disease, or surgical wounds need clinical wound care rather than…

  20. Hyaluronic Acid

    4.5–5.0 /10 for wound healing 6.5–7.0/10 overall Worth trying Vitamin & Mineral & Nutrient

    HA is a genuine extracellular-matrix component and topical and dressing forms are used clinically for wounds, but high-quality oral-supplement outcome data for everyday wound healing is thin. Mechanistically plausible and used in…

  21. TRT (Testosterone Replacement Therapy)

    4.5–5.0 /10 for wound healing 5.5–6.0/10 overall Neutral Hormone Therapy

    Androgen replacement may support protein synthesis and tissue repair in deficient men, but direct human wound-healing evidence is limited. Surgical clearance and standard wound care matter more.

  22. LL-37 (Cathelicidin)

    4.0–4.5 /10 for wound healing 4.5–5.0/10 overall Neutral Immune Peptide

    Wound healing is the one use case with real human evidence, which is why it scores highest. In a first-in-human topical trial of 34 people with hard-to-heal venous leg ulcers, LL-37 at…

  23. Semaglutide

    4.0–4.5 /10 for wound healing 6.0–6.5/10 overall Worth trying Metabolic & Incretin Peptide

    Improved glycemic control may help diabetic wound biology, but appetite suppression and inadequate nutrition can impair healing.

  24. Spermidine

    3.5–4.0 /10 for wound healing 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Animal wound-healing rationale exists, but no human wound-healing RCT support was verified.

  25. Astaxanthin

    3.5–4.0 /10 for wound healing 7.5–8.0/10 overall Strong recommend Vitamin & Mineral & Nutrient

    Antioxidant support for healing is reasonable but dedicated wound-healing RCT evidence is limited.

  26. KPV (Lys-Pro-Val)

    3.5–4.0 /10 for wound healing 7.0–7.5/10 overall Strong recommend Immune Peptide

    KPV may support a lower-inflammatory repair environment through NF-kB modulation, and Xiao 2017 found nanoparticle KPV accelerated mucosal healing in a mouse UC model. Direct human wound-healing evidence is absent.

  27. Tirzepatide

    3.0–3.5 /10 for wound healing 6.0–6.5/10 overall Worth trying Metabolic & Incretin Peptide

    Better glycemic control can support wound risk in diabetes. Calorie restriction, low protein intake, dehydration, and nausea can impair healing. There is no tirzepatide wound healing trial. Keep low and reserve any…

  28. Blood-Flow Restriction Training

    3.0–3.5 /10 for wound healing 8.0–8.5/10 overall Strong recommend Resistance & Strength

    Improved blood-flow dynamics after cuff release are theoretical support, but direct wound-healing evidence is limited.

  29. Colostrum

    3.0–3.5 /10 for wound healing 6.5–7.0/10 overall Worth trying Vitamin & Mineral & Nutrient

    Colostrum growth factors can support epithelial repair models, and topical uses appear in reviews, but oral bovine colostrum is not established as a human wound-healing intervention.

  30. Fucoidan (Brown Seaweed Polysaccharide)

    3.0–3.5 /10 for wound healing 6.0–6.5/10 overall Worth trying Vitamin & Mineral & Nutrient

    Wound and tissue-repair data are animal and in-vitro only.

  31. Tesamorelin

    3.0–3.5 /10 for wound healing 6.0–6.5/10 overall Worth trying Growth Hormone Secretagogue

    GH can support tissue repair, but tesamorelin-specific wound-healing trials are absent. This rating remains low-moderate because the intervention is not clinically established for wounds.
