If you love the bright, tangy flavor of key lime pie, you’re going to love this Key Lime Pie Protein Shake.
It’s creamy, refreshing, and tastes like a slice of homemade pie while providing more than 30 grams of protein to help keep you energized throughout the morning.
Made with vanilla protein powder, collagen peptides, creatine, Greek yogurt, and fresh lime juice, this easy protein shake comes together in just a few minutes. It’s one of my favorite healthy breakfasts during the spring and summer months.

Tips for the Best Key Lime Protein Shake
Fresh lime juice gives this shake the brightest flavor, but bottled key lime juice also works well.
The frozen banana adds natural sweetness without overpowering the lime flavor.
For an even creamier shake, use ultra-filtered milk in place of almond milk.
Why Add Collagen?
Collagen peptides blend right into this smoothie without changing the flavor. I often add a scoop for an extra protein boost and an easy way to increase my daily protein intake. This is the collagen I love.
Adding collagen may help support:
- Healthy skin
- Strong hair and nails
- Joint health
- Healthy connective tissue
Why Add Creatine?
Creatine isn’t just for athletes.
Research shows creatine may help support:
- Muscle strength
- Exercise recovery
- Lean muscle maintenance
- Healthy aging
- Brain health
Creatine is virtually flavorless, making it an easy addition to smoothies and protein shakes. Simply blend it in with the other ingredients. This is my favorite creatine supplement.
Protein Breakdown (Approximate)
- Vanilla protein powder: 30g
- Greek yogurt: 10g
- Collagen peptides: 9-10g
Total Protein: Approximately 49-50 grams
Even with a lower-protein powder, this smoothie still provides well over 30 grams of protein.
