CHICAGO — GHOST has expanded its whey protein lineup with three new cereal-inspired flavors developed in partnership with General Mills. The new Cereal Milk products are based on the flavors of Cocoa Puffs, Lucky Charms, and Trix, bringing well-known breakfast cereal profiles into the sports nutrition category.
The launch extends an ongoing collaboration between GHOST and General Mills that has previously produced limited-edition supplements inspired by familiar snack and dessert brands. The new flavors are now available through the company’s direct-to-consumer website and select retailers across the United States.
Each product is part of the brand’s GHOST WHEY platform and contains 25 grams of whey protein per serving, 130 calories, and is gluten-free. According to the company, the formulations also include digestive enzymes and avoid amino spiking: a practice sometimes used in protein supplements to artificially inflate protein counts.
A nostalgic flavor strategy
The product launch builds on the brand’s long-standing “Cereal Milk” concept: protein powders designed to mimic the flavor of leftover milk after eating cereal.
According to Dan Lourenço, the new products revisit one of the brand’s earliest ideas.
“The very first GHOST WHEY flavors we launched in 2016 were Cereal Milk products,” Lourenço said in a statement accompanying the announcement. He explained that the expansion with General Mills allows the brand to lean into flavors that many consumers already associate with childhood breakfasts.
Among the three products, the Lucky Charms Cereal Milk flavor contains real Lucky Charms marshmallow pieces, adding texture as well as flavor to the protein powder.
The company said the move reflects its broader approach of combining performance-focused supplements with recognizable consumer brands.
Why it matters
Nostalgia-driven flavor collaborations have become a major marketing strategy across the CPG sector, particularly in the functional food and sports nutrition categories.
By partnering with established cereal brands, companies like GHOST can tap into decades of brand recognition while differentiating their products in a crowded supplement market. The approach also reflects a broader trend in which snack and breakfast brands extend their intellectual property into adjacent categories such as protein bars, shakes, and fitness supplements.
For cereal manufacturers, licensing agreements with supplement brands create new revenue streams while reinforcing cultural relevance with younger consumers who may not regularly purchase traditional breakfast cereals.
