Our pediatrician and also a few reputable sites on the Internet come to the conclusion that instead of synthetic cyanocobalamin, a natural and bioactive form methylcobalamin is preferable. Also in this respect scores Jarrow so.
The price I find ok, with a pack's enough to just over 8 months. The kids tastes, while sucking you can still receive a portion of the B12 directly through the oral mucosa. Full marks. Unless, of course, including the next-B12 blood test. MMS and holoTC determining the values drop out worse than at the last test. So I did not expect and would also edit here again the review.
