Product Description:

It's generally recommended that adults consume 25 to 35 grams of fiber per day, but most Americans only get about half that amount. Fiber's value to athletes and health conscious individuals is centered on its important role in digestive support. If you are not consuming enough fruits and vegetables to meet your fiber needs, adding a teaspoon of Fitness Fiber to beverages, protein shakes, oatmeal or bowl of cereal gets you 5 grams closer to achieving your goal – with only 10 additional calories.

  • Contains a blend of 6 different fiber sources (Polydextrose, Fibersol-2, Inulin, Guar Gum, Psyllium Seed Husk, Gum Arabic)
  • 5 Grams of Fiber, Only 10 Calories per Serving
  • Add to drinks, shakes, or breakfast cereal.

jeffbevan - 11/3/2015 mixes well, no gritty after taste or feel. Does what its suppose to do.
aljasmi - 10/14/2015 اول منتج أشاهده وأستعمله خاص للالياف.. منتج رائع لمن يرغبون بزياده استهلاك الالياف وتجنب الاكل بكميات كبيره.. فهو يمدك بما تريده من كميات الالياف لبناء العضلات بسعر مناسب ولكن لاتجعله المصدر الوحيد للالياف وقم بدعمها بمصادر بطيعيه من الالياف في الاطعمه..
will definitely purchase again.
Valler - 10/6/2015 I ordered this to supplement my daily fiber intake, and thus far it's worked very well. I mix a teaspoon with my evening bowl of low-fat cottage cheese. It mixes very well, and there is no flavor that I can detect. I have not experienced any gastrointestinal issues or upset stomach from using this supplement, which was an initial concern prior to trying it. This is exactly what I was looking for, and will definitely purchase again.
A clump of fiber.
tinatian1990 - 9/27/2015 The main reason I bought this product was to get some extra fiber in my diet and a lot of the reviews said it was great escpcially with the price and the best part it mixed so well. I really like this product. I like the price. But I really don't like clumps in the bottom of drink from this product. Overall it is smooth and you can't taste the any powder or pastey taste... But when you reach the bottom you just can't drink the last drink thanks to a clump of fiber.
goes down just fine.
dsburk - 7/24/2015 I take this product to supplement the fiber lost on a high protein diet. The flavor is true to word, it has no taste. I mix it with a protein drink in the morning, it doesn't seem to dissolve very well but still goes down just fine.
Adding fiber to your diet is never a bad idea
ajsjps - 7/8/2015 Really useful supplement to add quick, tasteless fiber to protein shakes and water. Adding fiber to your diet is never a bad idea, and this allows you to do it easily.

Ahmed - 6/12/2014 When it will be available again?????

yazan - 4/23/2014 They did not lie when they said it has no taste. I add this in my smoothie every morning and it does not effect the taste.
