Product Overview

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

Beyond The Basics

  • Contains a blend of several different fiber sources
  • 5 g of fiber per serving
  • Only 10 calories
  • Unflavored versatility
  • Mixes easily

It takes about 4-5 days of heavy use to get the relief your looking for. Meanwhile you'll be dealing with uncontrollable gas...morning, noon, and through the night. As well as dealing with mad bloating and feeling totally defeated by this stuff. Not to mention...way too much carbs per teaspoon. A high fiber whole grain bread or spaghetti works a lot better in my experience.

I've used a tub of this product and will probably re order it. It seems to help boost my fiber levels and it blends pretty well. Price is good too. I take it in the morning with some bcaa that is flavored.

Getting fiber from real food is really a challenge for me. I never hit the recommended dose. My digesting is way better after this, and always feel fuller. I don't recommend mixing it with post-workout protein shake because it defeats the purpose of quick digestion. But through the day, i mix it with the snack shake. Also try adding it do different recipes like adding 3 tbsp to cake mix. Basically, add this with any sugary food.

This is a great product to make my protein shakes more like a meal, as I try to lose weight. No flavor, and it mixes well. I wish it had more fiber per serving- though it does have very low calories. Also, I wish that they had a larger size, as this container doesn't last me too long. But all in all a great product- good price as well.
