**Q: Two questions: 1. What is the source of the vitamin B12 in this formula? 2. What does HFF stand for?**
A: I realize Amazon has the HFF in the name/title but I looked at my bottle and no where on the bottle is this abbreviation displayed nor does it say those letters anywhere on the bottom in description, directions etc. I have been using these for quite a while now and I can just tell you it is a product I will continue to use and buy from amazon. It has a great strawberry flavor, dissolves quickly under the tongue and taste good. I hope this helps!

I have been using this product since 2023 and couldn’t find it anymore at my original store. These are great and taste really good. I take these due to Metformin can deplete Vitamin B-12.
