This Strawberry Grapefruit Smoothie is bright, refreshing, and perfect for hot summer days. It uses simple, everyday ingredients and requires no specialty powders to be delicious and satisfying.
With just a few clean ingredients this smoothie delivers a fruity burst of flavor while keeping you full until your next meal. The recipe is family-friendly and easy to adapt.
If you prefer a protein boost, adding your favorite protein powder turns this into a complete meal without feeling heavy. On lighter days this smoothie hits the spot and works well for those following the Trim Healthy Mama style, categorized here as an E-style option.
When protein powder isn’t on the grocery list, a budget-friendly alternative is 1/2 cup 0% Greek yogurt or 1/2 cup 1% cottage cheese. Both provide a creamy texture and a good source of protein, making the smoothie more filling without adding unnecessary ingredients.
Using these simple swaps demonstrates that a healthy eating plan can be affordable and approachable, even without specialty products.

I sometimes use a clean whey isolate when it’s available because it mixes well and adds creaminess, but it’s entirely optional. Choose what works for your taste and budget.
- 1/2 cup 1% cottage cheese or 0% Greek yogurt
- 1/2 cup unsweetened almond milk (or milk of your choice)
- 1 tablespoon sweetener (I used Pyure Organic Stevia, or use your preferred sweetener)
- 1 teaspoon vanilla extract
- 1/8 teaspoon glucomannan powder (optional)
- 1/2 grapefruit, peeled
- 1/2 cup frozen strawberries
- 1 cup ice cubes
- Combine cottage cheese (or Greek yogurt), almond milk, sweetener, vanilla extract, and peeled grapefruit in a blender. Process until smooth.
- Add frozen strawberries and blend until incorporated.
- If using glucomannan powder, sprinkle it over the mixture and blend briefly to combine.
- Add up to 1 cup of ice cubes and blend to your desired consistency.
