The B12 injections given in doctors' offices in the US are usually cyanocobalamin, which is the cheapest form of B12 and which must be decyanated by the body before it can be used. (Methylcobalamin is more bioavailable and is available by prescription through compounding pharmacies.) Most people, but not all, can use the sublingual form of B12. Both cyano- and methyl-cobalamin are available in the sublingual form; check the label to know which one you are buying.kzosche wrote:I will have to have my neuro fax the blood test to me to see my vitamin D level at the time he told me it was high. I was taking 10,000 mg per day at the time. I have since cut that to 5,000. It's Metagenics High Potency Bioavailable D3 5000. It is non-GMO. As for the B12, I never had my vitamin B levels tested. Both the vitamin D and B12 were taken because I was told to take them; not because I was told they were low. I was originally receiving B12 by injection in the arm. It was quite painful. I began taking it orally. This is also Metagenics. It's Intrinsi B12 Folate. This is also non-GMO.
I will get access to the D blood test results and give you those numbers.
Are you a doctor? Are you someone with MS? Are you someone conducting a study?
In my opinion (I have no medical training), it would be a good idea to request at least the serum B12 test in order to be certain your body is absorbing B12 properly as far as the bloodstream (The other initial testing usually includes a folate test, a homocysteine test, and a methylmalonic acid test.). (Even if the serum B12 looks good, it is still possible to have a functional deficiency in the cells/tissues if all the B12 is on the wrong transporter molecule in the blood.)
I was diagnosed with MS in September, 1992. At that time, none of my doctors tested either my vitamin B12 or my vitamin D levels – I feel that these tests should be routinely performed. (My vitamin D level in January 2016 was 24 ng/ml!) Some neurologists recommend 80 to 100 ng/mL for people with MS/neurological symptoms. I am very curious to learn your vitamin D status.
I commend you for seeking out expert advice (in the form of Dr. Fox) on the issue of breast implants and MS. It is important for people to take an active role in their own health.
