Markets 
Protein is having a cultural moment, and celebrities are cashing in. From Khloé Kardashian’s popcorn to Venus Williams’ plant-based shakes, a wave of star-backed nutrition brands is reshaping the snack aisle and turning macros into marketing.
Understanding who is behind each brand, and what actually sets the products apart, helps shoppers cut through the hype.
How the Celebrity Protein Boom Works
The formula tends to be similar across launches. A celebrity partners with (or cofounds) a nutrition company, then builds the product around a specific protein claim. Sometimes the pitch is convenience. Sometimes it is a specific health angle like brain support or muscle recovery.
Kardashian’s Khloud line applies milk protein isolate to two familiar snacks. Its protein popcorn and protein chips both deliver seven grams of protein per serving.
Writing for Food Network, Sabrina Choudhary noted, “Like the popcorn, Khloud Protein Chips contain seven grams of protein per serving. For context, the Institute of Medicine recommends that adults eat 50 to 175 grams of protein per day, based on a number of factors including age, body weight and exercise. (Most Americans already consume enough protein.)”
Khloud popcorn ships in flavors including White Cheddar, Sweet & Salty Kettle Corn, Olive Oil & Sea Salt, Cinnamon Roll, Truffle & White Cheddar, Dill Pickle and Birthday Cake, plus a Jalapeño Queso exclusive release. Its chips come in Nacho, Sweet Heat and Buffalo.
Which Celebrities Have Their Own Protein Brands?
The roster keeps growing.
Venus Williams, Happy Viking. The tennis champion’s line centers on plant-based protein powders and shakes. According to Happy Viking, “The brand’s flagship superfood protein and meal replacement powders are built around a “30/10 rule,” meaning they deliver 30g of plant-based protein (from pea and brown rice sources) and 10g of fiber per serving. They also include over 100 superfoods, vitamins, probiotics, and DHA-Omega 3s designed for muscle recovery, brain health and immunity.”
Patrick Schwarzenegger and Maria Shriver, MOSH. MOSH bars are marketed as protein bars with a brain-health focus rather than a straight muscle-recovery snack. Core Protein Bar flavors include Peanut Butter Chocolate Crunch (Shriver’s favorite), Chocolate Brownie Crunch, Cookie Dough Crunch, Blueberry Almond Crunch, Lemon White Chocolate Crunch, Birthday Cake and Cookies & Cream. The High Protein line, delivering 20 grams per bar, comes in Peanut Butter Cup, Chocolate Sea Salt and Oatmeal Chocolate Chip.
Mel Robbins, PureGenius Protein. According to the brand, “Pure Genius Protein shots are 100 calories, zero sugar, zero fat, shelf-stable and gluten-free, with no artificial flavors or sweeteners. It has a surprising, fruit-forward flavor, zero chalkiness and tastes just like drinking juice.” Flavors include Blueberry Lemonade, Strawberry Guava, Watermelon Berry, Lemon Lime and Pineapple.
Mark Wahlberg, Performance Inspired. Wahlberg’s line spans protein powder, protein bars, pre-workout, creatine and recovery supplements, with its whey protein delivering 25 grams per serving. According to the brand’s website, Wahlberg cofounded Performance Inspired Nutrition with Tom Dowd after the two bonded over what they saw as a lack of clean, effective supplements on the market and a frustration with artificial sweeteners, fillers and synthetic ingredients in existing products.
Zac Efron, Kodiak Cakes. Efron helped launch an Apple Brown Sugar Pecan Oatmeal for Kodiak Cakes that packs 14 grams of protein per packet. According to PR Newswire, the oatmeal is “packed full of some of Zac’s favorites including chia seeds, pumpkin seeds and cranberry seeds” and adds prebiotic fiber. In a press release reported by Bailey Fink at Allrecipes, Efron said his goal was “to create an oatmeal that’s really delicious, and really good for you,” with less sugar and more nutritious ingredients.
Why the Celebrity Protein Trend Matters for Shoppers
The wave of star-backed products is more than a marketing curiosity. It reflects how mainstream high-protein eating has become, and how much premium consumers are willing to pay for a familiar face on the label.
Most Americans, as Choudhary noted at Food Network, already consume enough protein for their daily needs. That makes the trend as much about lifestyle branding as nutrition science. Reading labels, comparing grams per serving against price and knowing what claims a brand actually backs up matters more than ever.
