Advanced Two Stage Delivery:
Zahler's upgraded Bioactive B Complex is a two-layered tablet with layer 1 (half of the nutrients) released and delivered immediately. The delayed release of layer 2 (the other half of the nutrients) enables sustained benefit. Since the B vitamins are water soluble and quickly metabolized and excreted, the benefits of slow release include more stable blood levels and an increase in the total amount of nutrients being absorbed and utilized.
