About You

KPV is a tripeptide composed of the amino acids lysine, proline and valine that has emerged as a promising therapeutic agent for its anti-inflammatory and mucosal protective properties in gastrointestinal disorders. The peptide’s mechanism of action involves selective antagonism of toll-like receptor 4 (TLR4) signaling pathways, modulation of cytokine production, and reinforcement of epithelial barrier integrity through upregulation of tight junction proteins such as occludin and claudins. By dampening the innate immune response to luminal antigens, KPV reduces neutrophil infiltration and oxidative stress within the gut mucosa, thereby alleviating symptoms associated with inflammatory bowel disease, celiac disease and irritable bowel syndrome.



Peptides for Gut Health



Larazotide acetate (also known as AT-1001) is a synthetic peptide that mimics a segment of zonulin. It functions by binding to the zonulin receptor on enterocytes, thereby preventing the disassembly of tight junctions and restoring intestinal barrier function. This action reduces antigen translocation across the epithelium and has shown efficacy in celiac disease and other leaky-gut conditions.



Apigenin is a flavonoid that exerts anti-oxidative and anti-inflammatory effects by inhibiting nuclear factor kappa B activation and reducing pro-inflammatory cytokines such as tumor necrosis factor alpha. In gut health, apigenin supports mucosal healing and reduces epithelial cell apoptosis during inflammatory insults.



BPC 157 (body protection compound) is a pentadecapeptide derived from human gastric juice. It promotes angiogenesis, fibroblast proliferation, and nerve regeneration. In the gastrointestinal tract BPC 157 accelerates ulcer healing, restores motility, and protects against ischemia-reperfusion injury by modulating nitric oxide pathways and preserving mitochondrial function.



Butyrate is a short-chain fatty acid produced by colonic bacterial fermentation of dietary fibers. It serves as the primary energy source for colonocytes and exerts anti-inflammatory effects through histone deacetylase inhibition, leading to increased expression of mucin genes and tight junction proteins. Butyrate also stimulates regulatory T cell differentiation, contributing to immune tolerance in the gut.



L-Glutamine is a conditionally essential amino acid that fuels enterocyte metabolism. It maintains crypt cell proliferation, enhances barrier function by supporting the synthesis of glutathione and mucin, and reduces intestinal permeability during stress or disease states such as sepsis and inflammatory bowel disease.



Functional Medicine



In functional medicine, gut health is considered central to overall wellness because chronic inflammation in the gastrointestinal tract can drive systemic diseases including autoimmune disorders, metabolic syndrome, and neuropsychiatric conditions. Practitioners employ a personalized approach that integrates nutritional optimization, lifestyle modification, and targeted supplementation with peptides like KPV, larazotide, BPC 157, butyrate, apigenin and L-glutamine to restore the gut barrier and immune equilibrium. Functional medicine also emphasizes addressing root causes such as dysbiosis, food sensitivities, and environmental toxins while monitoring biomarkers of inflammation, permeability and microbial metabolites.



PRP Injections for Shoulder Pain in Philadelphia: A Non Surgical Alternative



Platelet-rich plasma (PRP) therapy has become an attractive non-surgical option for chronic shoulder pain, particularly among patients seeking alternatives to arthroscopy or rotator cuff repair. In Philadelphia, numerous clinics offer PRP injections that utilize the patient’s own blood, which is processed to concentrate platelets and growth factors such as platelet-derived growth factor, transforming growth factor beta and vascular endothelial growth factor. When injected into the glenohumeral joint, subacromial bursa or tendinous structures, these growth factors stimulate fibroblast proliferation, collagen synthesis and angiogenesis, thereby accelerating tissue repair and reducing pain.



Clinical studies from local orthopedic centers demonstrate that PRP injections can provide significant improvement in shoulder function scores and decrease opioid usage compared with placebo. Patients typically receive one to three treatments spaced 4–6 weeks apart, followed by a tailored physical therapy program aimed at restoring range of motion and strengthening the rotator cuff musculature. The minimally invasive nature of PRP, coupled with its autologous origin, reduces the risk of rejection or infection, making it an appealing option for individuals who prefer to avoid surgical intervention while still seeking durable relief from shoulder pain.
