Mostly I trust Mercola over other brands and in terms of purity, you seem to just pay a bit more. This tastes good, I can spray throughout the day or bit more if need. I am little so can do 4 sprays I figure so lasts longer! I combine with Dibencozide for fatigue and nerve repair, good for MTHFR people or anyone. I also carefully added this to DMSO (99.8% Pharm Grade in glass bottle) and applied topically, seemed to work even better!? (kept me awake). Am using it for severe PHN nerve pain so also adding OptiMSM and colloidal silver to that mix. It just doesn't last long so I wish there was more of it, at higher concentration, and perhaps in glass. I wonder if container is recyclable too? Please don't use the synthetic cyanoB12 (this is the only type of B12 in Australia which is ridiculous!) - I used it for years and it did nothing for my B12 problem except give me cyanide which then my body has to detox out somehow.

Thanks for your feedback!

Used this for my 2 year old

The doctors were pushing to give my little guy vitamin B-12 injections. I went with this instead in addition to other natural remedies and his condition improved. He asked for this every day until it was gone! ;)
