In older age, vitamin B12 absorption tends to be less efficient due to a range of health issues, including gastritis stomach lining inflammation and thinning but also because of decreased production of stomach secretions (EFSA, 2015

Six months of voluntary wheel running significantly downregulated the expression of Ferritin, HO-1, janus kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), DMT1, TFR, and hepcidin in the cerebral cortex of five familial Alzheimers disease (5FAD) mice, reduced A and IL-6 levels, inhibited A plaque deposition and neuroinflammation, thereby improving neurological deficits in AD mice ( 2 max significantly downregulated the levels of TFR1, TF, DMT1, FTL, FTH, mitochondrial Ferritin, -secretase, and APP in the cortical motor regions of aged amyloid precursor protein-C105 (APP-C105) mice, upregulated the expression of FPN1, Furin, and -secretase, significantly reduced Fe 2+ , Fe 3+ , and total iron content, inhibited brain iron accumulation and A plaque growth, thereby improving learning ability, memory, and cognitive function in aged APP-C105 mice ( G93A transgenic mice, significantly reduced the expression of FTL, FTH, Ferritin, TFR1, and APP, upregulated FPN1 expression, inhibited A and iron accumulation in skeletal muscle, and improved neural function in the mice

On a therapeutic note, some microbiota-targeted treatments have reduced protein aggregates in models: long-term broad-spectrum antibiotics reduced A deposition and microglial reactivity in an AD mouse model, and recolonization with a simplified microbiota reversed some of these effects, indicating that specific microbial communities can either exacerbate or ameliorate protopathic cascades [102]
Peptidings position is that Pattern A is the more defensible bet if someone is running GLOW at all, and that Pattern B requires a substantially higher sourcing bar to be remotely reasonable
