I misunderstood....
I had purchased the 5000 mcg sublingual tablets and I loved the flavor and how they dissolved, but they were too potent for every day use. I prefer to take them daily so I don't lose track of when I took one, so I ordered the 1000 mcg version but I didn't realize that they were NOT sublinguals... I can take pills but I enjoyed the little fruity treat every morning...it reminded me of being a kid and taking my vitamin....now I'm back to being an old lady having to swallow a pill... but on a good note the 1000 mcg tablets do work well, and they were a great price and are easy to swallow...so I can't complain about the actual product...I just wish they had been sublingual like the 5000mcg ones...

no bad taste, may be a little troublesome to swallow
i haven't been taking them long enough to determine the benefit so my next doctors appt i'll update the review with if it's actually helpful or not - but in terms of flavor, no offending taste on the tongue or after taste in the back of the throat. i have a few issues swallowing because of the shape, i think the pills would benefit from more rounded edges, but other than that it's a good value for the price.

Best B12 supplement available OTC
This supplement has been very easy to integrate into my daily routine. I usually take it right after breakfast. This has helped keep my blood pressure in check. Definitely ditch the prescription medications and opt for this instead.
