This chart may be useful as an overview: What Are The Symptoms of Vitamin B12 Deficiency
BPC-157 is often researched for its potential ability to support tissue healing, joint recovery, and inflammation response
Peptides like Selank and Semax, primarily known for their anxiolytic and cognitive effects, may have indirect benefits for psoriasis through stress reduction
Additionally, Vitamin C plays a crucial role in maintaining glutathione in its active, reduced state, while adequate levels of B-vitamins (particularly unmethylated B12 and folate) are necessary to support the methylation cycle that drives natural glutathione production
This points to the possibility that the peptide could influence extracellular matrix maintenance, hydration, and skin barrier strength in laboratory settings
