Raised my numbers!
I was diagnosed as B12 deficient with a number of 163. After 6 months of injections, my numbers were only up to 505. My Dr decided to try me on supplements so I chose these based on my research. They were high dose, methyl B12. I have been on acid reducing medication for some time and was afraid regular pills may not get absorbed properly so I liked that these dissolve in your mouth.I take them on an empty stomach and let them dissolve on top of my tongue, not under. The taste is practically non-existent to me so it’s not an issue. They dissolve quickly. After about 2 1/2 months of taking 1 a day in the manner I just described, I had blood work done to check my numbers. I stopped taking them about a week before getting the blood work done to be sure I got an accurate number. Imagine my shock when my B12 level was up to 1797! These tiny little pills did in less than 3 months what injections couldn’t do in 6 months!Highly recommend these for anyone that is deficient, they really do work!

It works.It works.
I had some Low B-12 and B6 so did two consecutive boxes of these daily and as the lab tests show you— they work.
