I experienced it again, due to the same reason, going vegetarian/vegan for health reasons. I didn't go to for blood work this time, I just knew. I bought the higher dose B12. Not only is the taste really delicious, but I felt better immediately. I will not stop buying this product., and I've also tried to be better with getting in more protein as well. I highly recommend this product! ### ⭐⭐⭐⭐⭐ SUBLINGUAL *by on Reviewed in the United States July 19, 2025* Must have vitamin! Dr. Orders and this is top of the line!
