Bioactive B-Complex formula

Advanced timed release formula with a two-stage delivery system

Contains the B Vitamins in methylated, phosphorylated, and coenzyme forms

Supports the nervous system and energy production

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 copmlex 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) enable 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.

B complex

I always supplement with a B Complex, but this is by far the best I've ever tried. I literally feel great after taking these.

These are very absorbable and make me feel great.


I'm not sharing my name, but my personal experience I'll share. I'm 23 years old and had a bedwetting issue until recently. My mother told me that she heard from someone who heard from someone... that a B-complex is sometimes a solution (I was warned that it doesn't always help - but for some people it does). Well, I tried, and I was from the lucky few that saw results from a B complex for bedwetting. I take 1 pill 3 times per day, every day.

This is better than any other B Complex I tried, and I tried many. This lasts longer in the body and is absorbed very well.

extended relief

I love this this is extended relief and that you have the Bs for a longer time
