I have to quit the spirulina because it makes me dizzy when I lay down. Too bad because I am back on the B12 for neuropathy.Replied By Tracy (Hamilton, Nz) on 01/28/2013
Hi, just in response to the person talking about B12 being in Spirulina, it is not active B12, it is B12 analogues. They won't have the same function as B12 in your body although they will make your blood results look like you have plenty of B12. The only way to be sure you have good B12 levels is not by getting your blood levels tested, rather you should get your MMA tested. If you are only getting B12 from spirulina your MMA will come back abnormal. Chlorella on the other hand has worked for me, the B12 in it doesn't appear to be analogues, MMA comes back normal.Replied By Elise (Houston, Texas) on 06/29/2022
I wonder what kind of B12 you're on? If you're on cyanocobalamin you might need to switch to methylcobalamin. Some people's bodies don't know what to do with cyanocobalamin. Pure Encapsulations has a daily vitamin with methylcobalamin and also B12 that is Adenosyl/Hydroxy cobalamin. These have helped me. Maybe they will help you.
