Recommended by my M.D.
Size: 1.46 Pound (Pack of 1)
My M.D. told me to use this daily. It tastes a bit like "Tang" but that's fine. The fiber is good for regular bowel movements, but it also gives you a feeling of fullness which is helpful in reducing hunger sensations. So, it can help with weight loss. Be sure you get the sugar-free.

Love the taste and great for digestive system. They recommend doing a 14 day challenge so tried it was presently surprised with bloating, regularity and glad to be getting needed fiber. Also had elevated cholesterol so hoping this helps as well.
