Vitamin B Complex is a blend of eight highly absorbable B vitamins in their active forms to help optimize important metabolic activities throughout the body. B vitamins are essential to our most basic cellular metabolic activities. As coenzymes, they help regulate and support the enzymes that make our bodies work, helping us to get energy from food, and to make neurotransmitters for brain and nerve function. Nordic Naturals Vitamin B Complex is an expertly formulated combination of activated B vitamins featuring methylfolate (MTHF), a vitamin critical to DNA synthesis and important during pregnancy, and B12 as methylcobalamin in an amount designed for general cellular metabolic support.
