Question: What is the lowest dosage of vitamin B12 you recommend? If shots are not available, do you recommend B12 tablets?

Dr. Brownstein's Answer:

Injectable B12 works much better than oral doses. However, if you can’t get a doctor to prescribe the natural, injectable form of B12, then oral dosing is a reasonable alternative.

I recommend using either hydroxyl- or methyl-cobalamin for oral dosing, and I suggest using it sublingually (under the tongue). The usual dosing is 1,000 to 2,000 mcg per day (1 to 2 mg per day).

Vitamin B12 deficiency, which is common among people older than 50 and those with chronic illnesses, can cause or mimic many health woes including almost any neurological problem, such as depression, fatigue, brain fog, confusion, neuropathy, Alzheimer’s disease, multiple sclerosis, fibromyalgia, chronic fatigue syndrome, and Parkinson’s disease. More information about vitamin B12 can be found in the March 2009 issue of my newsletter "Natural Way to Health."
