I would speak to your pharmacist in case there are some contra-indications.
I am not a follower of the fatigue school and I think the supplements in some cases may actually do damage rather than good...
I would see someone like a naturalpathic doctor who can explain the ingredients in supplements that you buy in stores. My doctor explained why injectable b-12 does not process in body due to an ingredient that is used that some people can't process.
What ingredient is that?
I know the body cannot process if there is an intrinsic factor issue and needs more, but the B-12? My mom took the shots for years for pernicious anemia.
Oh it works for many, mostly seniors, but doesn't not get processed by everyone. That's all.
