Are you sure it's cyanocobalamin? Those are cheaper, but I actually thought methylcobalamin was more efficient.

I actually have one in my mouth right now. :D
You can check this article here ... isonSN.pdf; it compares the different types of vitamin B12.
It's not only the cheapest; your body absorbs a max. of about 1.5-2 mcg of cyanocobalamin at a time (after that, you B12 receptors become saturated), + 1% that goes into your blood (so if you take 250 mcg, it's 1.5 mcg + 2.5 mcg(1%) = 4 mcg). With methylcobalamin you must take a mugh higher dose to have the same mcg absorbed (the recommended dose is 1000-2000 mcg per day).
Both doctor Greger (you can find him on Youtube, trustworthy channel) and Jack Norris, both vegan, recommend cyanocobalamin ( ... ld-i-take/), but both cyano and methyl are perfectly fine.
For evil to prevail, good people must stand aside and do nothing.
