Unless the cause of burning sensation is established, giving medicines blindly may not be very rational. Eldervit contains vitamins A, B-1, B-2, B-6, B-12, niacinamide, vitamin C and vitamin D. If your burning sensation is not due to deficiency of one or more vitamins, no purpose will be served. Decades ago, it was thought that deficiency of vitamins B-1, 6, 12 might be responsible for peripheral neuritis leading to burning sensation. However, there was no evidence of such a theory. Consequently, all preparations of vitamins B-1, 6 and 12 were banned in all advanced countries including India. In order to escape ban (purely for commercial gain), some manufacturers resorted to adding other ingredients of hardly any clinical use. Thus Neurobion (banned) became Neurobion Forte. In your case if at all there is suspicion of vitamin B factors deficiency, the rational approach is to get blood levels of vitamins B factors (B-1, B-2, B-6, B-12) checked and then take a factor in which there is deficiency.
