I've had two (2) different versions of beta glucan. The first off of a store room shelf cost around $85 and performed well. This Jarrow brand looked much more cost effective, so I decided to take a chance. After working my way through the bottle, I'd have to say that there was no noticeable improvement in my condition. I did suffer a pronounced allergic reaction to the Jarrow brand. I wouldn't recommend this product.
