Overview

Thorne Basic B Complex provides all 8 B vitamins in their most bioactive forms: 5-MTHF (methylfolate) instead of folic acid, methylcobalamin instead of cyanocobalamin, pyridoxal 5'-phosphate instead of pyridoxine, and riboflavin 5'-phosphate instead of riboflavin. These active forms bypass the enzymatic conversion steps that many people (especially those with MTHFR variants) cannot perform efficiently. Thorne is the official supplement partner of the Mayo Clinic and is trusted by over 47,000 healthcare practitioners.
