Vegans and Vegetarians: B12 is found almost exclusively in animal products, so those on plant-based diets must use fortified foods or supplements Older Adults: reduced stomach acid can decrease B12 absorption from food as we age People with Pernicious Anemia: this autoimmune condition prevents the body from making intrinsic factor, a protein needed for B12 absorption Individuals with Gastrointestinal Conditions: diseases like Crohn's or Celiac disease can impair nutrient absorption Patients Who Have Had Gastric Surgery: procedures like gastric bypass can reduce the body's ability to absorb B12 Certain Medications: drugs such as Metformin and proton pump inhibitors (PPIs) can interfere with B12 absorption Medically-Approved vs
Published preclinical protocols and community-derived references typically use about 250 mcg once or twice daily by subcutaneous injection
Patients on this protocol who also use metabolic support agents like Metformin should note that both agents activate AMPK, and physician oversight is warranted to avoid compounding effects on blood glucose that could theoretically cause hypoglycemia in susceptible individuals, though this has not been reported clinically with MOTS-c at standard doses
By targeting multiple phases simultaneously, the GLOW protocol prevents bottlenecks that might limit healing from single-peptide approaches
