The well-known geriatrician-haematologist Larry Solomon, working at Yale University in the USA, wrote 20 years ago: if I had treated only those people who actually had too low serum B12 and elevated MMA values, then I would not have treated approximately two-thirds of the people with a favourable response to B12 supplementation (note: partly via injections, partly via oral supplementation)
