Natural Factors B12


I've just started taking some Natural Factors B12 I order from the Big Online Suppier.

I usually have Solgar or jarrow but these are cheaper. They are methylcobalamin and they're 5000mcg as the others have been.

They dissolve at a reasonable rate as I was finding the Jarrow ones were taking about 30 minutes under my tongue!

Does anyone have experience of these NF ones?

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.

Yours sound fine.

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!


I bought them a couple of months ago.


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! :(
