Unflavored original texture with sugar is the best!
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
I don't why the fake orange flavor is so popular. Unflavored is neutral and agreeable. Even with the sugar this product is very low glycemic index because the tiny amount of sugar is offset by the fiber.

Works but VERY thick
Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
Thought I was ordering the orange flavor, which I can drink, successfully. The unflavored, sugar free is what I actually ordered. My fault, not the seller, but the difference, for me is huge! I can't choke it down. Flavor is completely neutral, it isn't that. But, seems so much thicker than the orange. ? Maybe it isn't, could be that the thickness of the orange is same but I can trick myself into thinking its orange pulp. Who knows. But, in any event, the unflavored definitely seems like I'm drinking mud. I can't do it. Too bad, too, because the product is VERY effective. I have colitis/IBS and the Metamucil brand works so much better than anything I've tried, in helping with GI issues, in general. Increased regularity, more comfortable passing, and over time, a GI cleansing that you can actually feel. I highly recommend the product, but you might want to pay extra for the orange flavor. Might make the difference in you being able to drink it with the consistency required for best results.

Flavor Name: Original Coarse Sugar, Size: 1.86 Pound (Pack of 1)
Bought this to keep regulated... didn't check that it was unflacvored... suffered through the first week of taking this just as is before someone said to add a splash of water flavor
