How Does a Sublingual B12 Stack Up Against B12 Injections?
In studies performed on the sublingual B12 products it is found that a 1000 mcg B12 tablet are as effective as the B12 Injections. All of the sublingual B12 have a warning (not to swallow whole) there is no need to worry about it being unsafe. The problem here is you do not get the proper absorption and it is passed through the body without getting the benefit of it.
