"Looks like my B complex has the cyanocobalamin. It has a lot of stuff including folic acid and an herbal blend."

You may want to consider finding the methylated forms of folate and B12 (see cut-and-paste below). I have read that this helps many with the MTHFR mutation. The mutation can inhibit the methylation of folate and cyanocobalamin, so many with MTHFR mutation do not get the benefit when taking the common forms.

MTHFR Treatment: The Complete Guide
MTHFR Treatment
The treatment of MTHFR mutations is often a two-pronged approach. First, supplemental methylfolate and methylcobalamin directly address dysfunction in methylation pathways. Second, it is important to adopt appropriate lifestyle habits to down-regulate epigenetic expression of MTHFR mutations.

Supplements
The two most common supplements used to treat MTHFR mutations are methylfolate and methylcobalamin, both of which are methylated forms of B vitamins. The forms of these B vitamins found in typical multivitamins and supplements are not methylated. It is important to choose methylated forms to ensure adequate absorption and utilization.
