Hello, Well, since the recent news of how poorly efficacious most multivitamin/multi-mineral preparations do their jobs has become publicized it grounds my feelings that I ve had for many years which is anything of a MULTI-anything is likely, not worth the capsule covering it comes in. And Nurokin Gold is no exception in my opinion. If your right middle finger is numb early morning only then, I wouldn t necessarily be suspicious of a nutritional deficiency so much as I might be concerned about a VASCULAR deficiency or a compression phenomenon going on at least over part of the MEDIAN NERVE that sub-serves sensory function of that finger. I would also recommend measuring serum levels of whichever B vitamin your doctor is apparently concerned about that would cause such an ISOLATED presentation of 1 single middle finger on 1 hand (not a likely presence of a B12, B6, folate, or niacin deficiency in my opinion). Then, based on those lab results I would prescribe the direct and single entity to the patient as necessary. Otherwise, I might consider doing vascular Doppler studies and possibly an EMG/NCV study and maybe even an Ultrasound of the carpal tunnel which could avoid having to stick needles into the arm/hand. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Dariush Saghafi, Neurologist
