I wanted to test also my Zinch level, but I still wasn't able to find a Lab that is doing it. In India I was 3 years ago, it looks like a long time ago, to have the effects now, but maybe it's possible.
About the Methyl B12, unfortunately it's not approved in Italy. What I have now, I bought when I was abroad. And even shipping it it's not working, because if they find it, they block it at the custom. The maximum I can find is 2000 mcg of Cyanocobalamin from Long Life brand.
