Review: 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.
Review: Value + - The 21st Century B12 1000 mcg Prolonged Release Tablets are a real bargain. I’ve noticed a difference in my energy levels, and the prolonged-release formula makes them easy on the system. Good quality, effective, and very affordable—definitely recommend if you need a reliable B12 supplement.
