My 97 year old mother (who is normally like a spring chicken) had started to get tired legs when out shopping in the last couple of years and having to sit down. This stared happening more frequently and she has had a couple of falls, feeling dizzy etc. The last fall broke her arm but she has recovered amazingly well. Through thesse falls they did a heart scan which shows she has two leaky valves and her heart is only working at 20 percent. I asked for a b12 check and it has come back at 330 which they say is adequate with folate levels of 3.30. I told the doctor about the appropriate levels being 1000 in elderly people but she was quite angry at my insistence that she be treated. Anyway, to cut a long story short, I want the best for my mum, whilst accepting her age, and have ordered 5000mg methylcobalamin lozenges for her. I just want to make sure these won't do her any harm before giving them to her. My sister also got herself checked and her folate levels are 2.7 with b12 levels of 205. She has been pestering her doctor for years with CFS but they refuse to treat her also. I get so angry with the doctors in this country's blind refusal to treat people with low scores. I just don't want to do my mum any harm by giving her these, I just want the best for her. Anyone know if these would harm her ??
