Ingredients You’ll Need

• Berries – a great source of fiber and antioxidants. Any combination of frozen or fresh berries will do. I use frozen blueberries, raspberries, and strawberries but blackberries or even cranberries would also work well. If you choose to use fresh fruit, you’ll probably want to add a few ice cubes to get that frosty texture. 

• Flaxseed – this affordable seed adds healthy fats like omega 3 fatty acids to help lower inflammation levels. I love this ground flaxseed option.

• Rolled oats – whole grain oats add some prebiotic fiber to really help improve gut health and thicken up the smoothie for a great consistency.

• Protein powder – adding a scoop of your favorite protein powder is a great way to add protein. Whey protein powder, plant based protein powder, or collagen peptides are all great options.

• Monk fruit – this is a naturally occurring sweetener that is sweeter than sugar, however, it doesn’t affect blood sugar levels – a huge win for those of us with PCOS! If you’ve never tried monk fruit before, I highly recommend it. This is my favorite monk fruit sweetener. Of course, you can always omit this ingredient entirely!

• Vanilla extract – vanilla extract adds to the flavor profile of this smoothie with its slightly sweet taste and aroma.

• Greek yogurt – Greek yogurt adds gut healthy probiotics and creaminess to the smoothie. It’s also a great source of quality protein as well to keep you feeling full. 

• Almond milk – I love using almond milk in smoothies because it’s light but you can use any type of milk you enjoy.

How to Make a Triple Berry Oat Tropical Smoothie

All you’re going to do is put all of the ingredients into a high speed blender and blend for about 30 to 60 seconds until it’s smooth.

Pour into a glass and enjoy! 

How To Store It

This smoothie is best enjoyed immediately, however, it can easily be prepped in advance and stored in an air-tight container in the refrigerator for up to 24 hours.

Variations, Substitutions, + Tips

• No flaxseeds? Hemp hearts or chia seeds would be a great option to substitute.
• If you’re dairy-free, substitute collagen peptides or a plant based protein powder for whey protein and substitute a plant-based yogurt for greek yogurt
• Substitute stevia, honey, or another sweetener for monk fruit
• Substitute orange juice, coconut water, or coconut milk for the almond milk for a more tropical tasting smoothie
• No rolled oats? Substitute quick oats, millet, amaranth, brown rice, or simply omit them.
• Use any combination of fresh or frozen berries that you enjoy
• Add a handful of baby spinach for a nutritional boost
• Make a double batch and freeze into popsicle molds for a filling frozen treat
