Excellent product

Posted by 4677902882042607339 on May 07, 2015

I need to supplement both b12 and zinc, so this is a good combination: b12 as methylcobalamin and zinc in picolinate form. Plus, it is good to know there are no preservatives and fillers in Thorne Research products and they are free of all major allergens.

One of the most hypo-allergenic

Posted by Reviewer1915683 on Sep 07, 2011

It contains one of the two only really working B12 metabolites (methylcobaline) with a high dose of Folic acid. Is one of the most hypo allergenic products I know Hans Reijnen, docter for Homeopathy and Bio-Information Therapy, the Netherlands
