Review: Works well and tasteless - I have to take iron pills and they can make you constipated so I take this powder in my coffee. It keeps me regular and no taste at all. I subscribe to it so I’m never out.
Review: Great stuff for gut troubles - I love Dr's Best - this product is recommended for people who have tummy issues. I've noticed this prebiotic fiber feeds good gut bacteria but doesn't cause gas or bloating or irritation. It has no discernible flavor. I like to mix it into my coffee or protein shake. It mixes easily without any clumps in both hot and cold beverages. It has helped with heartburn and other issues so I rate it as effective and Drs Best always has the best quality products in my opinions
