Expensive but good

Posted by 4839923227984656268 on May 22, 2015

Although expensive, it has all the major vitamin Bs in required high doses. I've ready a couple of health books eg for adrenal fatique and their recommendations for what a vitamin B complex matches what this brand offers. We are on a third bottle. Together with other nutrients and supplements my husband, who used to be anti-supplements, now finds he experiences less fatique and takes his vitamins regularly.

In my case this really helps with depression, being superior to other b complexes in that it has a higher content of b12, and both b9 and b12 are more easily absorbed.

Superior quality

Posted by bODYhACK3r on Jun 11, 2014

Gives you a zap in energy and verbal ease. As someone that tends to speak complexly and make jokes I can feel the effects on brainfog and such. I take it sublingually, that way you make sure that it will go to the bloodstream quickly and in high amounts. Highly recommended.
