I am another dissatisfied Country Life user... which I really didn't expect. I was looking for a good 5000mcg B12 and CL was particularly interesting because they only use xylitol as sugar, very little additives, no magnesium stearate, no citric acid.
The first test was disappointing because the lozenges disappear in your mouth in seconds and I definitely didn't get the "kick" I usually got from other 5000 sublinguals.
Then I tried the "between cheek and gum" approach for some time, again I didn't feel any effect but I kept going with those until after 3 weeks all sorts of symptoms had returned: irritability, pain in lower extremities, bad mood etc...
I finally decided to switch back to Source Natural's and voilà... immediate effect, bad mood gone almost the first day, and pain slowly went away after the first week of switching.
There is a definite and clear effect that I get when a lozenge works for me: pain lowers, brain fog dissipates and mood raises almost immediately. When that doesn't happen the supplement doesn't work, at least for me.
Solgar 5K and Source Naturals 5K both work great.
cheers
ETA: Enzymatic Therapy also works great but for the dosages I need I can't suck candies all day, plus there's too much sugar. Last year it definitely helped the worsening of my gut dysbiosis, probably because they use too much fructose.
