I have taken other forms of B12 and found them energizing, but this form wiped me out for several days.

This product only contains Methylcobalamin, not Adenosylcobalamin! Not happy!

I contacted Source Naturals to find out how much of this product is Adenosylcobalamin and was told that the product only contains Methylcobalamin! Not happy!! I am trying to recover from 25 years of migraines and have a double copy of the mthfr gene. It is hard enough to figure this out when you know what is in a product! I do not appreciate the deception in labeling by Source Naturals. If you buy any product from this company, first check that it is correctly labelled.
