Review: Good product - Great product. Goes down easy and I kinda like the taste even though it’s unflavored. It’s like you’re drinking bread. It does a nice job without overly binding and does not cause cramps. I’d like to see it without the green tea, but that would be beneficial for most people.
Review: Works Well - This fiber powder has been working really well for me. I just stir it into my morning coffee and don’t even notice it’s there. It mixes in easily without changing the taste much, which makes it simple to use every day. It’s been effective, and I’ll definitely keep buying it.
