Copycat Costco Sparkling Protein Water Recipe

7

I was so excited when I first discovered Costco Sparkling Protein Water. Each can packs a powerful punch with 30 grams of protein, a fizzy kick, and refreshing flavors like Blue Raspberry Lemonade—all without the guilt of extra sugar or carbs. But here’s the thing: as much as I love grabbing a case from Costco, I couldn’t help but wonder if I could recreate something similar at home.

How to make Costco Sparkling Protein Water

Costco Sparkling Protein Water is a clear, carbonated drink sold at Costco that combines the refreshment of sparkling water with the nutritional benefits of a high-protein supplement.

Ingredients

To mirror the flavors and nutritional benefits of Costco Sparkling Protein Water, you’ll need the following:

• Protein Powder (Unflavored or Flavored)
• Sparkling Water (Chilled)
• Lemon Juice (Freshly Squeezed)
• Sugar-Free Drink Mix or Syrup
• Ice (Optional)

Instructions

1. Prepare Your Protein Base: In a shaker bottle, mix 1 scoop (approximately 25-30g) of protein powder with 4-5 ounces of plain water. Shake thoroughly until the powder completely dissolves and no lumps remain. This creates a protein “base” for the drink without clumping in the sparkling water.
2. Add Lemon Juice and Sweetener: Stir in 1-2 tablespoons of fresh lemon juice.
3. Add a few drops or a small packet of a sugar-free drink mix or syrup. Adjust the amount to your desired sweetness level.
4. Combine With Sparkling Water: Slowly pour the chilled sparkling water into the shaker or a glass to prevent the fizz from bubbling over. Aim for about 8-12 ounces of sparkling water, depending on your preferred intensity of carbonation. Gently stir (don’t shake—sparkling water can be volatile!).
5. Serve Over Ice: Pour your drink over a glass filled with ice for an extra-cold, crisp sip.
6. Garnish (Optional): For a fun finishing touch, garnish with a slice of lemon, fresh raspberries, or even a sprig of mint.

Tips for the Perfect Sparkling Protein Water

• Protein Type Matters: Opt for a protein powder that mixes well with water and doesn’t become thick, such as clear whey isolate or plant-based versions designed for light, watery beverages. Avoid casein or milk-based powders, which can create a creamy texture that clumps in sparkling water.
• Experiment With Flavors: Costco Sparkling Protein drink comes in Blue Raspberry Lemonade, but the DIY version lets you mix things up! Try combinations like pineapple coconut, lime-mango, or strawberry kiwi for a customized experience.
• Adjust Sweetness Levels: If you prefer a less sweet beverage, reduce the amount of syrup or drink mix. If you like it sweeter, add a little more and adjust as you go.
• Use a Frother for Smoother Protein Blending: A handheld milk frother can help break down protein powder and create a smoother mix before combining with the sparkling water.
• Enjoy Immediately: Homemade sparkling drinks are best consumed fresh to maintain maximum fizz.

What to serve with

Costco Sparkling Protein Water is not just a drink—it’s an experience. With its refreshing fizz, high-protein content, and sweet, fruity flavors like Blue Raspberry Lemonade, it pairs perfectly with light, healthy, and flavorful snacks or meals.

1. Fresh Fruit Platters

Since sparkling protein water has fruity notes, serving it with fresh fruit enhances the citrusy and berry flavors.

Best Pairings:

• Sliced watermelon, pineapple, mango, and kiwi
• Mixed berries like raspberries, blueberries, and strawberries
• Citrus wedges such as orange, lime, and grapefruit

Why It Works: The natural sweetness and juiciness of the fruit complement the tangy sweetness of the sparkling water, creating a refreshing combo, especially on warm days.

2. Protein-Packed Snacks

Costco Sparkling Protein Water is already rich in protein, but pairing it with protein-packed bites creates a balanced snack or post-workout recovery option.

Best Pairings:

• Hard-boiled eggs with a sprinkle of everything bagel seasoning
• Greek yogurt parfait with granola and a drizzle of honey
• Turkey or chicken roll-ups wrapped with cheese and baby spinach
• Cottage cheese topped with fresh fruit or cinnamon

Why It Works: These protein-rich snacks complement the nutritional value of the drink and help keep you full and fueled for longer.

3. Healthy, Crunchy Snacks

Sparkling drinks pair wonderfully with a bit of crunch. Light and wholesome snacks can provide delightful textures and flavors.

Best Pairings:

• Air-popped popcorn (flavored lightly with nutritional yeast or sea salt)
• Veggie sticks (carrots, cucumbers, celery) served with hummus or a light dip
• Baked tortilla chips served with guacamole or fresh salsa
• Roasted chickpeas for a crunchy, savory protein boost

Why It Works: A touch of savory or earthy crunch creates a nice balance with the sweet, fizzy drink.

Ingredients Substitutes

Making your version of Costco Sparkling Protein Water at home gives you full control over the ingredients. The beauty of this recipe is its flexibility—if you don’t have a specific ingredient or are looking to tailor it to meet your dietary preferences, there are plenty of substitutes available.

1. Protein Powder

The key ingredient in any Costco Sparkling Protein Water copycat recipe is protein powder. While the original drink incorporates clear whey isolate, there are other substitutes to suit your dietary or flavor preferences.

Substitute Options:

• Plant-Based Protein Powder: If you follow a vegan or plant-based diet, opt for a pea protein isolate or rice protein. Look for blends labeled “light” or “clear” to avoid gritty or creamy textures.
• Casein Protein Powder: Although it creates a slightly creamier texture, casein can be used for those wanting longer-lasting satiety.
• Collagen Powder: Collagen protein powders dissolve well in liquids and are flavorless, making them an excellent substitute. They won’t mimic the fruitiness of whey isolate but will add a light, refreshing base.
• Egg White Protein Powder: Another light, flavor-neutral option for those avoiding dairy altogether. This is a great substitute for keto or paleo diets.

2. Sparkling Water

The fizz and bubbly sensation of sparkling water makes this drink fun and refreshing, but not all sparkling waters are created equal.

Substitute Options:

• Flavored Sparkling Water: Flavored varieties like LaCroix, Spindrift, or Bubly can add unique dimensions to your drink.
• Club Soda: Club soda can be used as a substitute if you have it on hand, though it might have a milder fizz compared to sparkling water.
• Tonic Water (Unsweetened): If you prefer a slightly more bitter twist, tonic water works—just make sure to choose a sugar-free version.
• Carbonated Water Maker: Use a home carbonation system like SodaStream to create your fizzy water.

3. Lemon Juice

Fresh lemon juice is used to bring a bright, tangy flavor to the drink that complements the sweetness. If you don’t have lemons on hand, there are other ways to introduce a tart or citrusy note.

Substitute Options:

• Lime Juice: Lime juice can provide a similar acidity with a slightly sharper, zesty flavor.
• Orange Juice: For a sweeter and less tangy alternative, freshly squeezed orange juice or even a splash of grapefruit juice can be used.
• Citrus Extracts: A few drops of lemon, lime, or citrus extract are concentrated enough to replicate the flavor without needing fresh fruit.
• Citric Acid Powder: A small pinch of food-grade citric acid powder can replicate the tanginess of lemon juice (but use sparingly to avoid overpowering the drink).

4. Sugar-Free Drink Mix or Syrup

The sugar-free drink mix or syrup is what infuses the drink with sweetness and bold fruit flavor. If you don’t have this, there are several ways to achieve sweeter, flavorful results:

Substitute Options:

• Fresh or Frozen Fruit: Blend in a handful of fresh or frozen raspberries, strawberries, or pineapple chunks for natural sweetness and flavor.
• Fruit Juice: Use a splash of 100% fruit juice, like cranberry, apple, or pomegranate juice, for a natural base. Just be mindful of added sugars.
• Stevia Drops or Liquid Sweeteners: For a sugar-free option, add a few drops of liquid stevia or monk fruit sweetener along with a splash of natural fruit juice for flavor.
• Flavored Liquid Water Enhancers (e.g., Mio, Stur): These convenient squeezable flavor enhancers come in various flavors and are often sugar-free. Simply adjust based on your preferred sweetness.
• Homemade Syrups: Make your sugar-free syrup by simmering water with natural sweeteners like erythritol and flavored extracts.

Final Thoughts

Costco Sparkling Protein Water is incredibly versatile and pairs beautifully with a variety of snacks and meals.
