Unlike other brands I have purchased in the past (which I was satisfied with), the texture of the product (powder) makes it clump and not dissolve completely in water. If you leave it in water for a while to dissolve the clumps, it thickens so much that it becomes a mass that you cannot swallow! On the first day, I dissolved it in hot water, and the result was terrible (a cup full of clumps). On the second day, when I dissolved it in cold water to avoid clumps, I had to eat it... with a spoon. Terrible! I will not buy it again. (The only good thing: it was effective regarding the expected action).
