Berry–Banana Collagen Smoothie: A Simple, Nutrient-Packed Recipe

Unflavored collagen powder is easy to add to foods you already enjoy—and a smoothie is one of the simplest places to start. This berry–banana blend pairs collagen with fruit, leafy greens, yogurt and nut butter for a convenient mix of protein, fiber, vitamins, minerals and satisfying flavor.

The ingredients do not change what collagen is or guarantee a specific health result. Instead, they add a wider variety of nutrients to the same glass. Always use the serving amount and preparation directions listed on your collagen product.

Berry-Banana Collagen Smoothie Recipe

Makes: 1 serving
Prep time: 5 minutes

Ingredients

  • 1 serving unflavored collagen powder, measured according to the product label

  • 1 cup frozen strawberries

  • 1/2 medium banana

  • 3/4 cup plain Greek yogurt

  • 1 cup baby spinach, loosely packed

  • 3/4 cup milk of choice, plus more as needed

  • 1 tablespoon almond butter

  • A few ice cubes, optional

Directions

  1. Add the milk to a blender first, followed by the Greek yogurt, collagen powder, almond butter, spinach, banana and strawberries.

  2. Blend until smooth, stopping to scrape down the sides if needed.

  3. Add more milk for a thinner smoothie or a few ice cubes for a colder, thicker texture. Blend again.

  4. Pour into a glass and enjoy right away.

Preparation note: Collagen products can differ in serving size and mixing instructions. Follow the label on your specific product rather than using a standard scoop amount.

What Each Ingredient Brings to the Blend

Unflavored collagen powder

Collagen powder supplies collagen peptides and protein; the exact amount varies by product. Check the Supplement Facts panel for the serving size and protein content. Supplements complement the diet—they do not replace the variety of foods that supports overall nutrition.

Strawberries

Strawberries contribute vitamin C, fiber and naturally occurring plant compounds. Vitamin C is required for the body’s own collagen synthesis and also functions as an antioxidant. This does not mean that adding strawberries makes a collagen supplement more effective; it simply makes vitamin C-rich fruit part of the recipe.

Banana

Banana adds natural sweetness, carbohydrates and potassium. Potassium is an essential mineral involved in normal cell function, including nerve transmission and muscle contraction.

Plain Greek yogurt

Greek yogurt makes the smoothie creamy while adding protein and calcium. Choosing plain yogurt helps limit added sugar; check the Nutrition Facts label because nutrient amounts vary by brand and style.

Baby spinach

Spinach adds leafy-green variety along with nutrients that include vitamin K and folate. Its mild flavor is easy to blend with berries and banana.

Milk of choice

Dairy milk contributes protein and calcium and is commonly fortified with vitamin D. Fortified soy milk can offer a similar protein boost, while other plant-based milks vary widely. Compare labels and choose an unsweetened, fortified option when that suits your needs.

Almond butter

Almond butter adds creamy texture, unsaturated fat, some protein and vitamin E. Vitamin E acts as an antioxidant in the body. Choose a product that fits your taste and dietary needs.

Make It Work for Your Routine

  • For a thicker smoothie: Use frozen fruit and start with less milk.

  • For a thinner smoothie: Add milk a tablespoon or two at a time.

  • For less sweetness: Use fewer banana slices and choose unsweetened milk and yogurt.

  • For food allergies or intolerances: Select appropriate substitutes and check every package for allergen statements.
