This is such a great product! I have a condition where I can only swallow very small amount of liquid at a time, so two things were very important to me: first, that it didn't have an offensive taste, and second, that it didn't "gel" too quickly (as it takes some time for me to finish 12 oz of liquid). I'm happy to say that this product is virtually tasteless (just a slight powdery taste which isn't bad) and it doesn't "gel" instantly. If I stir the water/glucomannan mix a couple of times during the time I consume it, it keeps it's water-like consistency for at least five minutes. I'm mainly taking this product to lower my blood sugar and it really seems to help and I've lost a bit of weight, too. And the price is right! Love this product and will definitely repurchase!

Good to lose weight

Posted by Reviewer2915423 on Jul 17, 2009

Just a little makes big difference. I took it when I am hungry between meals. Now I do not need snacks any more. And I lost some weight.
