high fiber smoothies

These high-fiber smoothie recipes are some of my favorite healthy breakfasts and snacks. Easy to blend up in just 5 minutes, they’re full of high-fiber ingredients like fruits, vegetables, nuts, and seeds. These good-for-you foods make these smoothies energizing and satisfying, but that’s not all. They also pack in the health benefits of fiber, including promoting gut health, aiding digestion, and lowering cholesterol.

Whether you’re actively trying to eat more fiber or are just looking for breakfast or snack ideas to try, you’ll love these high-fiber smoothies. They’re quick, easy, and nourishing…not to mention delicious!

5 High-Fiber Smoothie Recipes to Try

Green smoothie

Green Smoothie

According to the Cleveland Clinic, most adults need 25 grams to 30 grams of fiber per day. This refreshing, gut-healthy blend packs in 13 grams per serving—half the recommended daily fiber intake! That’s all thanks to almond butter, chia seeds, and a big handful of leafy greens.

High-fiber blueberry smoothie

Blueberry Smoothie

A secret veggie ingredient adds extra fiber and antioxidants to this sweet and tangy berry smoothie: frozen cauliflower! You can’t taste it, but it makes this recipe super-thick, frosty, and creamy.

Coffee smoothie

Coffee Smoothie

Add a little fiber, protein, and potassium to your morning coffee by blending up this sweet, cinnamon-spiced drink! Medjool dates, almond butter, and frozen bananas perfect its creamy texture and give it 6 grams of fiber per serving.

Avocado smoothie

Avocado Smoothie

Want to make the creamiest smoothie you’ve ever tasted? Toss some avocado into the blender! Mixed with spinach, lime juice, frozen pineapple, and vanilla protein powder, it creates a smoothie that tastes like a tropical sorbet…that just so happens to have 10 grams of fiber per serving.

High-fiber zucchini smoothie

Zucchini Smoothie

This smoothie is the closest I’ve come to sharing a chocolate milkshake on the blog. Medjool dates, almond butter, and cocoa powder give it a rich, sweet chocolate flavor. You’d never guess that you’re getting 7 grams of fiber as you sip it!

Easy Ways to Add Fiber to Smoothies

Don’t worry if you don’t have the exact ingredients to one of these recipes on hand. You can build your own high-fiber, delicious smoothies using a variety of whole foods ingredients. Here are some of the ingredients I turn to when I want to add fiber to a smoothie:

  • Chia seeds and flax seeds: When in doubt, just add chia seeds or ground flaxseed to any smoothie you’re making. A tablespoon of chia will add over 3 grams of fiber and flax will add around 2!
  • Berries: Berries are some of the highest-fiber fruits. For example, 1 cup of raspberries delivers 8 grams of fiber!
  • Banana: Bananas make smoothies sweet and creamy. 1 medium also adds around 3 grams of fiber.
  • Hidden vegetables: Fresh or frozen spinach, kale, zucchini, and cauliflower can all blend into fruit smoothies without affecting flavor.
  • Oats: Yup, you can blend whole rolled oats or quick oats straight into a smoothie for soluble fiber! They also add creamy texture. Try it out in this peanut butter banana smoothie!
