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.

Watch expiration
Delivery was fast and product was as I've ordered before the only reason I took one star away was the B12 I received expires two months before the one I'm replacing. Although that isn't until 2026 I would still expect the product I'm receiving to be more fresh than what it is replacing.

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.
