SixStar X Kellogg Cereal Protein Flavors

Six Star’s collaboration with Kellogg’s is built around a simple idea: take iconic, nostalgic cereal flavors and translate them into high-protein, affordable daily shakes that still fit real training and recovery goals. The lineup features officially licensed Kellogg’s Frosted Flakes® and Froot Loops® flavors, including the Birthday Cake Froot Loops variant, aiming to deliver fun, familiar taste profiles without turning protein into a novelty gimmick.

Across the entire Kellogg’s line, Six Star uses their 100% Whey Protein Plus formula, which is positioned as a muscle-building and recovery protein, delivering 30g of protein per serving alongside added vitamins and minerals for immune support. The partnership allows Six Star to lean heavily into flavor authenticity while maintaining macro consistency and mass-market accessibility.

Behind the Six Star Protein:

All three Kellogg’s flavors use the same Six Star 100% Whey Protein Plus formula, meaning macros and ingredient profiles remain consistent across flavors, with taste being the main differentiator.

Flavor Lineup

Kellogg’s Frosted Flakes®
Designed to replicate the classic sweet cornflake milk flavor, this one leans creamy, smooth, and easy-drinking. It is positioned as a daily shake option rather than a heavy dessert profile.

Kellogg’s Froot Loops®
Built around bright, fruity cereal notes, this is the most distinctive flavor in the lineup. It keeps the sweetness balanced while delivering a very recognizable cereal milk finish.

Kellogg’s Birthday Cake Froot Loops®
This version adds a cake-inspired twist to the standard Froot Loops profile, blending fruity cereal sweetness with vanilla cake notes. It keeps the same macros and protein content as the standard Froot Loops flavor.

Where to Grab it💰

Six Star’s Kellogg’s protein lineup is widely available across major retailers and Six Star’s own website, making it one of the most accessible licensed cereal protein collaborations on the market.

Primary purchase locations:

• SixStarPro.com

• Walmart

• Target

• Kroger

• GNC

Each tub contains approximately 18 servings and typically retails in the $19.99 to $29.99 range, depending on retailer and promotions. That puts the cost per serving around $1.10 to $1.60, which is extremely competitive in today’s protein market, especially for a branded collaboration product.

Final Thoughts

From a value perspective, this lineup absolutely delivers. The price per serving is extremely aggressive, especially considering the 30g protein dose, licensed flavors, and widespread availability. While this is not positioned as a premium ultra-filtered isolate or boutique protein formula, that is not its goal.

Flavor execution is solid across the board. Nothing here feels gimmicky or overly artificial, and none of the flavors try to do too much. They are straightforward, nostalgic, and easy to drink, which honestly makes them ideal for daily use, especially for beginners, students, or anyone wanting affordable, consistent protein intake.

Bottom line: this is good protein at a very good price, with flavors that are enjoyable, reliable, and accessible. Not flashy, not boutique, just dependable, budget-friendly performance fuel.
