Active B Complex™: High-Potency, Bioavailable B Vitamins*

Active B Complex™ by SFI Health provides a full complement of essential B vitamins in high-potency amounts and their activated, coenzyme forms. This advanced formula is specifically designed for optimal absorption and utilization, making it an ideal choice for individuals who may have difficulty metabolizing standard forms of B vitamins. It provides comprehensive support for energy production, metabolism, and the healthy function of the brain, liver, and nerve cells.*

How It Works: Activated Forms for Immediate Use

This formula bypasses the body’s need to convert B vitamins into their active forms, ensuring more immediate and efficient effects on metabolism.

Bioactive Folate and B12
Instead of standard folic acid, this complex includes Metafolin® L-5-MTHF, a bioactive form of folate that is directly usable by the body. This is paired with methylcobalamin, an active form of vitamin B12 that enhances absorption and bioavailability, ensuring maximum support for neurological health and metabolic processes.*

The formula also features benfotiamine, a lipid-soluble and highly bioavailable form of thiamin (B1), along with the active coenzyme forms of riboflavin (B2) and vitamin B6 (P-5-P).
