One of the side effects of being a diabetic is often feeling tired. Once I started taking the Natrol Vitamin B-12 5000 mcg I felt the difference within 3 days. I would highly recommend this supplement for anyone that is feeling tired and needs a boost of energy.
vitamin b12 is destroyed in the stomach I always used the under tongue pill, but have been unable to find these. nature of habit was thrilled to find these so purchased two bottles. thanks for listing.
