Conditions like pernicious anaemia (an autoimmune condition affecting a protein called intrinsic factor vital for B12 absorption), stomach issues (such as from reduced stomach acid or certain medications like proton pump inhibitors), intestinal disorders (like Crohns disease or coeliac disease), or even surgical removal of parts of the small intestine (e.g., gastric bypass surgery) can prevent proper absorption
Any yellow, brown, or other tint is a red flag
Research points to interaction with the nitric oxide system and growth factor signalling pathways involved in tissue repair
B12 injections are highly useful and have been proven effective, often considered the fastest treatment
Research-grade semaglutide is sold as a research compound
Never freeze reconstituted peptide solutions, as the freeze-thaw cycle can damage the peptide structure
