Hey LK-
I got mine from Amazon.com-I bought the vita cost brand, but have used now foods
glucomannan also in the past. I don't see any appreciable difference?
I'm taking 2 g at a time with 8 ounces of water what I'm absolutely ravenous and have no access, or it would be inappropriate, for Nicorette.
On a sidenote, in the evenings when I can only have protein I do make protein pudding from three glucomannan capsules, casein, some cinnamon, with a little bit of water until pudding like paste. It's pretty savvy at tricking your body into thinking of having something delicious, when in reality it's pretty ****ing disgusting.
