Do different brands of B12 affect people differently.......?

[BeachArt]

I have always used Rotexmedica/Panpharma (from GP and from Germany). Due to the recent shortage of that my GP gave me Gerot Lannach, and I am sure it wasn't as effective. I couldn't put my finger on it, other than I just didn't feel as good as using it. So I bought some Pascoe from Germany, and I am finding it as good as Panpharma, with the added bonus of it not stinging!I'm assuming that different brands have different preservatives in and that could be why........🤷‍♀️

I've had several brands Panpharma

Rotexmedica

Gerot lannoch

Neo

Cytomen

Accord

Cobalamin H

All hydroxcobalamin.

Only one I avoid as personally reacted badly to one of the additives I assume.

Some b12 injections still don't seem to give what I need .

No idea

why

As can be the same brands that gave good relief last time?

Thank you Nackapan. I was always good with Rotexmedica/Panpharma. Gerot Lannach just didn't seem to work as well for some reason. And I am finding Pascoe a good choice too, probably better than Panpharma if I am honest.Which brand did you react to? It is weird how different people react to different brands, and how some find one brand more effective than others.

Strangely it was Gerot and lannach I started on.Very strong response .

Unbearable at times firing up all nerves !!

[BeachArt in reply to Nackapan]

How strange! I felt that it was less effective for me.

Good on you for trusting you know!

There are 4 different types of b12 ampulls, all with different effects:

- hydroxocobalaminacetat

- hydroxocobalaminklorid

- cyanokobalamin

- metylkobalamin

Best and longest effect - hydroxocobalaminacetat. Both Panpharma/Rotexmedica, Pascoe 1500 and Erycytol (gerot lanach) are hydroxocobalaminacetat. But they are manufactured different, and we all can respond different.

Thanks for that! I have tried the different forms and all are effective for me. Thing is some are more effective.
