Bests & Worsts Reviews from Amazon

Pernicious anemia runs in my family. I was having all B12 deficiency symptoms including, chills, extreme weakness and complete exercise intolerance..... because i went off if my usual costly brand of B12. When I saw this product, how conscientious they seemed regarding purity and pricing, I went for it. It took one week of 4 sprays/day plus taking Progressive Labs B12) intrinsic factor (needed to carry B12 to your cells) for the horrible bone fatigue, chills, weakness to subside! The people behind this product seem very genuine and send AMAZING emails. Mary Ruth's....The only request I have is would you please somehow include intrinsic factor in your B12 so we don't have to get it from another company?
