    Good fiber supplement
    Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
    Good supplement, wish it came with a scoop. Sometimes there might be a “chunk” that doesn’t dissolve so you get to chew something with your drink, it happens rarely but does happen. Took a while but feel regular and easy to take if you do protein shakes everyday. No taste and mixes well.

    Confirmed GLP-1 Friendly and Easy to Use this isa staple in my home.
    Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
    I am so pleased with this Benefiber Daily Prebiotic GLP-1 Friendly Fiber Supplement Powder! As someone looking for GLP-1 friendly options, I can happily **confirm it is GLP-1 friendly** and works perfectly with my dietary needs. It's completely unflavored, which is fantastic because it doesn't alter the taste of my favorite drinks. I've made it a part of my daily routine by simply adding it to my morning cup of hot tea, and it dissolves quickly and completely without any grittiness. This is an excellent way to effortlessly boost my fiber intake and support my digestive health. Highly recommend!
