Are smoothies Bulletproof?

The problem with most traditional smoothie recipes is the sugar content. Fruits are considered more of a treat or a dessert on the Bulletproof Diet and should be limited.

Smoothies packed with fruit or kryptonite ingredients like peanut butter or soy milk may give you brain fog and sap your energy. This bright and creamy concoction is a mega-upgrade from traditional fruity (i.e. sugary) smoothies. Whole foods like Brain Octane Oil, avocado, and lemon juice blend into a drink so satisfying, you won’t even miss the added sugar. Two scoops of grass-fed protein and plenty of healthy fat make this the perfect keto-friendly pick-me-up or a post-workout meal.

Keto Green Lemon Smoothie

Prep Time: 10 min.
Total Time: 15 min.


  • 1/2 large avocado
  • 1/2 cucumber
  • 3 tbsp lemon juice
  • 2 cups organic baby spinach leaves, lightly steamed
  • 1/2 cup coconut cream or coconut milk
  • 1 tbsp. Brain Octane MCT oil
  • 1 scoop Bulletproof Unflavored Collagen Peptides 
  • 1 scoop grass-fed, undenatured whey protein
  • 1 cup ice
  • Xylitol or stevia to taste

Optional: Add just a few drops of food grade lemon essential oil in to take it to the next level!


  1. Add all ingredients except collagen to a high-powered blender and blitz until evenly combined, smooth and creamy.
  2. Depending on how thick you like your smoothie you can add in extra water and re-blend it until you reach your desired consistency.
  3. Taste and adjust the flavors if needed. Add the collagen last, and blend on low to avoid damaging the proteins.
  4. Pour into glasses and top with your chosen toppings. Enjoy!
