- No Boost of Energy; Tablets Get Rancid Easily -

Posted by Christal on Sep 19, 2011

I bought this hoping that it would give me a steady supply of energy throughout the 8-hour period the vitamins are released, but find that I had better energy boost when taking the normal kind instead of extended release. This is probably good to make sure there's a steady supply of B vitamins in the body AFTER you take your normal Vit. Bs tablets for that boost of energy. Update: Despite the desiccant pack in bottle, all the tablets went damp and developed rancid smell. They already had that typical unpleasant smell of B Vitamins to begin with, but after they got damp they started to smell like poo. I, too, had to throw out the rest of the bottle (80% left).

Great formula

Posted by Reviewer2776030 on Sep 02, 2011

I just wish there was less choline - it's a high dose on top of my multi, but a good formula for sure
