Tremendous product

Posted by Reviewer2882465 on Feb 28, 2008

My biggest complaint when trying to diet and using meal replacement products is that they always seem to leave me in a state of dire hunger within 2 hrs of consumption. This product, added to my blender of spiruteen protein drink and juice is phenomenal and I vouch for how well it keeps me on track w/o having a sudden crash and the overwhelming need then to want to stuff my face. They recommend 1/4 t. per drink, which sounds like too little, but believe me, it works just fine. One reviewer complained about it clumping, which is probably so, but if you put it in a blender (Hamilton Beach makes a terrific mini model that is perfect for making a meal replacement drink), you should have none of the clumping that someone else described. I'm definitely going to stick with this product for assisting me with my weight loss efforts!

I'm aware this is a product for slowing carbohydrates down to avoid higher blood glucose levels, and to help with weight loss. I'm also trying it in my gluten free baking as a fiber to help decrease crumbling.
