However, our study suggests that FUT2, through its regulation of the cross-talk between gut microbes and the human host, might explain a part of the observational association between serum vitamin B12 and BMI
Since B12 is found primarily in animal products, including meat, fish, dairy, and eggs, a substantial reduction in food intake can reduce B12 consumption below optimal levels, particularly for patients who were already borderline deficient before starting treatment or whose diets lean toward plant-based foods
NHS B12 therapy is evidence-based for documented deficiency, using hydroxocobalamin 1mg intramuscularly with standardised protocols
It will explain why obvious signs like cognitive decline and fatigue are often mistaken for normal aging, even by healthcare professionals
We typically recommend NAD+ infusions 12 times per week initially, then adjusting based on how your body responds
