Hi just looking for advice on supplements. My B12 was just within range 230 i think. Anyway to cut a long story short, one dr advised supplementing with over the counter supplements. next visit said we could not do further testing as I had now skewed the result. I have since come off the supplements and b12 went back down then told by different GP "why dont we just forget about all this" I am now back on jarrows 1000 since April. My question is does the supplement do the same job as injections, should I push to find why I have the problem. I have a lot of restless legs lately and am feeling very tired. Any advice welcome.
