Many people have low B12 vitamins in their systems which cause many side effects such as exhaustion and brain deficiency.
You can get B12 by eating certain foods, an injection or a vitamin supplement.
The old we get the least we absorb B12.
I personally can’t say taking high doses of vitamin B12 helped my Fibromyalgia any. Try it for yourself.
