Protective effect of nicotinamide mononucleotide against soybean isoflavone induced damage in mouse testis.

This animal model study investigated whether nicotinamide mononucleotide (NMN) could protect mouse testis tissue from damage induced by soybean isoflavones, examining potential mechanisms of cellular protection. The researchers found that NMN treatment provided protective effects against the testicular damage caused by isoflavone exposure in mice. This evidence is derived from an animal model study and therefore has limited direct applicability to human populations.

Host defense peptides as a new drug lead to a strategy for inflammatory bowel disease.

This review article examines host defense peptides (HDPs), particularly KPV, as potential therapeutic agents for inflammatory bowel disease (IBD), discussing their mechanisms of action in modulating immune responses and reducing intestinal inflammation. The authors synthesize evidence from multiple study types—including in vitro, animal models, and human clinical investigations—to evaluate HDPs as a novel drug development strategy for IBD management. The evidence level is review article, which synthesizes findings across human clinical, animal model, and in vitro studies rather than presenting original research data.

Regeneration or Risk? A Narrative Review of BPC-157 for Musculoskeletal Healing.

This narrative review examined the evidence for BPC-157, a synthetic peptide derived from gastric juice, in promoting musculoskeletal tissue healing across multiple tissue types. The review identified promising preclinical findings in animal models showing potential benefits for tendon, ligament, muscle, and bone healing, though human clinical evidence remains limited and mostly anecdotal. The evidence base is primarily animal model and in vitro studies, with very few human clinical trials available to date.

Development and evaluation of a novel prehospital antidote service providing methylthioninium chloride (methylene blue) for sodium nitrite poisoning.

This study describes how emergency medical services developed a treatment protocol using methylene blue as an antidote for sodium nitrite poisoning. Sodium nitrite poisoning causes dangerous levels of methemoglobin in the blood, which prevents proper oxygen transport. Methylene blue was used by specialized paramedic teams to reverse this life-threatening condition. This represents a specific emergency medical application rather than a general health supplement use.

Challenge of Corneal Ulcer Healing: A Novel Conceptual Framework, the “Triad” of Corneal Ulcer Healing/Corneal Neovascularization/Intraocular Pressure, and Avascular Tendon Healing, for Evaluation of Corneal Ulcer Therapy, Therapy of Neovascularization, Glaucoma Therapy, and Pentadecapeptide BPC 157 Efficacy.

This animal model study examined corneal ulcer healing mechanisms by proposing an integrated conceptual framework linking corneal ulcer healing, corneal neovascularization, and intraocular pressure changes, with comparison to avascular tendon healing processes. The research evaluated the pentadecapeptide BPC 157 as a potential therapeutic agent across these interconnected corneal pathology domains. The study presents a theoretical model for understanding corneal wound healing complications and proposes criteria for evaluating therapeutic interventions in corneal disease, though findings are based on animal model evidence.

Association between blood nicotinamide adenine dinucleotide levels and blood laboratory parameters at baseline and after nicotinamide mononucleotide supplementation in middle-aged healthy individuals: post hoc analysis of a randomized, double-blinded, placebo-controlled clinical trial.

This post hoc analysis of a randomized, double-blinded, placebo-controlled human clinical trial examined the relationship between blood NAD+ levels and various laboratory parameters in middle-aged healthy individuals, both at baseline and following nicotinamide mononucleotide (NMN) supplementation. The study identified associations between NAD+ levels and specific blood biomarkers, with changes occurring after NMN supplementation in this population. **Evidence level: Human clinical trial**

Distinctive Gene Expression Profiles and Biological Responses of Skin Fibroblasts to Nicotinamide Mononucleotide: Implications for Longevity Effects on Skin.

This human clinical study examined how nicotinamide mononucleotide (NMN) affects gene expression and biological responses in skin fibroblasts, with the goal of understanding potential longevity-related effects on skin. The researchers identified distinctive gene expression profiles in fibroblasts exposed to NMN and characterized the resulting biological responses that may be relevant to skin aging processes. This is human clinical-level evidence investigating NMN’s direct molecular effects on skin cells involved in collagen and structural protein production.

BPC 157 Therapy: Targeting Angiogenesis and Nitric Oxide’s Cytotoxic and Damaging Actions, but Maintaining, Promoting, or Recovering Their Essential Protective Functions. Comment on Józwiak et al. Multifunctionality and Possible Medical Application of the BPC 157 Peptide-Literature and Patent Review. Pharmaceuticals 2025, 18, 185.

This review article examined BPC 157, a synthetic peptide, and its proposed mechanisms of action related to angiogenesis and nitric oxide regulation in protecting against cellular damage while maintaining protective functions. The authors discuss BPC 157’s multifunctional properties and potential medical applications based on existing literature and patent data, suggesting the peptide may modulate harmful versus beneficial effects of nitric oxide and angiogenesis. The evidence presented is from a literature and patent review (evidence level: review article).
