The New Soda That Sold Out in 2 Weeks Is Finally Back and Available in 2 New Flavors

With protein-packed products and better-for-you bevs dominating the food market this year, it’s no surprise that Protein Diet Coke—a spin on dirty soda that substituted coffee creamer with a nutrition shake—went viral last October. But what about consumers who can’t stand the texture or creaminess of protein shakes and still want their bubbles with a boost?

Rather than piling on the protein with shakes, powders, and supplements, Clean Simple Eats is back with a new spin on the macro-packed trend that’s perfect for an afternoon pick-me-up. And given how fast the first iteration of the product sold out, you might want to check it out sooner rather than later.

New Clean Simple Eats’ Protein Soda and Frosted Lemonade Restock

After its debut in early 2025, Clean Simple Eats’ first clear protein soda, Frosted Lemonade, quickly flew off shelves and proved that clear protein is having a moment. The easy-sipping functional formula is ideal for consumers looking for refreshing options that still bring the protein, minus the full, blended shake.

Now, CSE is expanding its line of clear and functional protein beverages with two new flavors: Cherry Lime and Classic Grape. Just like the OG Frosted Lemonade, both Cherry Lime and Classic Grape flavors are packed with 20 grams of grass-fed whey protein isolate (which means a low lactose content that can be easier on digestion) and zero added sugar. And, of course, Clean Simple Eats’ Protein Soda still features the signature fizz for the soda-style feel. Both flavors will join the fan-favorite Clear Protein lineup and be available in 16-ounce cans exclusively on the brand’s site.

In addition to the two new flavors, CSE’s Frosted Lemonade will also be returning to the lineup for a total of three flavors. Frosted Lemonade features the signature tart and juicy lemon flavor you’d expect, complemented by creamy vanilla for a sweet finish.

Fans couldn’t be happier, according to reviews on the product page. “Literally happy as a clam that this is back in stock. It is delicious, not too sweet and a great flavor balance! One of the best protein options I have ever tried,” exclaimed one.

Given that Frosted Lemonade initially sold out within two weeks, it may be worth heading to CSE’s website ASAP to snag a taste of the two new flavors. And, while you’re there, consider restocking on the tried-and-true protein lemonade while it’s still available.
