Lessons in biology from patients with inborn errors of vitamin B12 metabolism

Key metabolic effects include: Enhanced lipolysis through activation of fat breakdown pathways independent of growth hormone receptors Suppressed lipogenesis reducing conversion of non-fat substrates into stored fat Increased fat oxidation and energy expenditure in multiple species models No adverse effects on insulin sensitivity or glucose metabolism, unlike full-length growth hormone Independence from IGF-1 Signaling A critical distinction of AOD-9604 is its lack of IGF-1 pathway activation: No measurable changes in serum IGF-1 levels in human clinical trials Absence of growth-promoting effects on tissues No impact on blood glucose regulation or insulin resistance Avoidance of typical growth hormone side effects including edema and tissue overgrowth Metabolic Pathway Modulation Research indicates AOD-9604 influences energy metabolism through multiple mechanisms: Increased whole-body fat oxidation rates in animal models Enhanced metabolic rate without stimulant-like effects Potential modulation of uncoupling proteins in adipose tissue Effects on lipid metabolism that persist beyond plasma clearance Critical Mechanistic Gap: Despite extensive research, the primary receptor target for AOD-9604 remains unidentified

Dietary Deficiency: If your deficiency was purely due to diet (e.g., a vegan not supplementing) and youve since adjusted your diet or started regular oral supplements, you might eventually be able to space out injections more or even switch to oral maintenance, though this should always be carefully managed by your GP
That's why we must top it up through our diet - meat and dairy products are particularly rich in B12
Cyanocobalamin supplements help by providing the needed vitamin B12
