Avoid Bloat

Fiber is vital for a healthy digestive system, and is lacking in most people’s diet. It supports regularity, proper microbial levels, and ease of eliminations.

Gut Friendly

Oat bran fiber supports satiation and nutrient absorption. It is also high in beta glucans, a prebiotic fiber shown to help improve cholesterol.

Getting in Your Fiber

We designed our products to be easy-to-mix, match, and modify — so your body gets what it needs to prepare, perform and recover.

  1. Getting in your Fiber
    Start with 1 scoop and work up to as many as 4 scoops of fiber per day. Add to any liquid such as your Gainful Protein or Hydration. Has a mild, pleasant taste that mixes easily into any drink. The journey is just as vital as the end result. Progress is the point. Enjoy the gains as they come.
  2. When to Take
    We suggest mixing Fiber into your daily routine whenever it suits you best.
  3. Keep it Consistent

    Jossy M

    I’ve tried multiple protein powders on the market and find them to be too chalky and too sweet for my taste. This is a game changer! Light, airy, smooth - PERFECT!
