Medical conditions affecting absorption warrant particular attention : Pernicious anaemia : an autoimmune condition destroying gastric parietal cells, requiring lifelong B12 injections Gastrointestinal surgery : particularly gastric bypass, gastrectomy, or terminal ileum resection Inflammatory bowel disease : Crohn's disease affecting the terminal ileum impairs absorption Coeliac disease : untreated disease damages the small intestine, reducing B12 uptake Medication use : long-term metformin therapy (MHRA safety alert) or nitrous oxide exposure Symptoms suggesting possible B12 deficiency include : persistent fatigue, weakness, paraesthesia (pins and needles) in hands or feet, glossitis (sore, red tongue), mood changes, memory problems, or unexplained anaemia
Half-life and clearance timing Peptide half-life determines initial clearance rates
We constantly monitor your symptoms and energy levels to adjust this frequency, ensuring you stay in the optimal zone for health rather than just the minimum required range
Track specific markers including pain levels (using a consistent 0-10 scale), range of motion, visible swelling, and functional capacity
