Patients often report an energy change within days largely attributable to B12 where deficiency exists
Hydroxocobalamin is the standard UK preparation, administered intramuscularly for conditions like pernicious anaemia and gastrointestinal malabsorption B12 acts as a cofactor in DNA synthesis, red blood cell formation, and nervous system function, supporting energy metabolism pathways Common side effects include injection site reactions, mild gastrointestinal upset, and temporary urine discolouration, with serious reactions being rare NHS access requires GP assessment with blood tests
This makes B12 and B-Complex therapy a great option for boosting energy, supporting mood, strengthening immune health, and improving overall nutrient absorption, especially for those who may not absorb vitamins well through food or supplements, which is common

Where These Numbers Come From NAD+ replenishment targets several interconnected aging pathways, all driven by the age-related decline in NAD+ levels: Sirtuin activation: NAD+ is required for SIRT1-7 function deacetylases that regulate DNA repair, mitochondrial biogenesis, inflammation, and stress resistance
