Definitely work!
These B12 supplements have been great. About a year ago I found out I was quite low on B12. I actually had to get B12 shots for a while. After I was back to a more normal level I was told to use these. I was worried that supplements wouldn’t help, but these dissolve right under your tongue and so it goes right to your bloodstream. When I went back recently I was actually at the high end of normal!! These dissolve pretty quickly, taste alright, and are pretty small. Definitely would recommend.

Best B12 supplement available OTC
This supplement has been very easy to integrate into my daily routine. I usually take it right after breakfast. This has helped keep my blood pressure in check. Definitely ditch the prescription medications and opt for this instead.
