High-Fiber Breakfast Smoothie (With Oats, Chia & Berries)
A thick, velvety high-fiber breakfast smoothie blending rolled oats, chia seeds, antioxidant-rich berries, spinach, and almond milk with 13g of natural fiber.
Introduction

Hitting daily fiber targets can often feel like a chore if you are relying solely on raw salads and legume bowls. This high-fiber breakfast smoothie was designed to make fiber intake effortless, delicious, and deeply satisfying. By combining rolled oats, chia seeds, and whole frozen berries, it naturally delivers both soluble beta-glucan fiber and insoluble fiber to nourish beneficial gut bacteria and keep you full until lunchtime.
Unlike store-bought bottled smoothies that are loaded with fruit concentrates and stripped of pulp, every sip here retains the natural cellular structure and seeds of whole produce. Discover our complete Drinks collection or pair this smoothie with High-Fiber Overnight Oats for meal prep variety.
