might as well buy a b-12 supplement in tab form from your pharmacy.Youre wasting the whole point of synthelamin if you drink it... Which is both improved absorption and timed release.
Yes, you'd need to inject the Sythelamin(b-12). It's the liver protectant, Synthergine that can be administered via oral or inject. BTW, both products are the best out there that you can obtain.
