B-Complex

Zahler B-Complex is formulated with a unique two-stage delivery system, with half of the nutrients released immediately and the other half delayed for sustained benefit and enhanced absorption. This advanced formula includes only body-ready (coenzyme, methylated and phosphorylated) forms that don't require complex conversion. The B vitamins are critical for general well-being and specifically support mood, energy, and nervous system functioning.

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.

The two-stage delivery really does the trick—I feel the energy kick right away, and it doesn’t fade out by mid-afternoon like other B vitamins I’ve tried. The delayed release makes a noticeable difference in how steady I feel all day.

I’ve been taking these for a couple of weeks now and I really notice the difference in my energy level by mid-afternoon, which is usually when I crash. The way the B vitamins release in two stages makes sense for keeping things steady all day.

The two-stage delivery is what sold me, and I can feel the difference in my energy without that jittery crash I used to get from other B vitamins. The delayed release actually seems to keep things steady through my afternoon slump.
