If B12 tablets take too long to dissolve under tongue they are not sublingual. I have also bought solgar and they didn't dissolve and I've complained to them but I haven't had time to take it further. The solgar I always bought previously did dissolve but not the new ones.
I haven't had a problem with Solgar, although I haven't bought them for a while. When did they change? It's the Jarrow ones that take ages - and it says on the bottle that they're sublingual!
Looking on my account I last bought them in February, then when I came to get some more the price had shot up so I got the Jarrow ones. Now it seems the only Solgar ones are sold in pairs and cost about 65% more than when I bought in Feb!
