Gut Friendly

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

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.
