Two Essential Nutrients, One Small Shot
NEW YORK, Sept. 1, 2026 /PRNewswire/ — Pure Genius Protein, the nutrition company co-founded by Mel Robbins, today announced the launch of Protein + Fiber shots, the brand’s first major product innovation since its debut. Combining 20 grams of high-quality protein with 5 grams of fiber in a convenient 3.38-ounce shot format, the new product was developed to address one of the most critical nutrition gaps: approximately 95% of Americans fall short of recommended fiber intake, making fiber one of the most underconsumed nutrients in the American diet.

Developed alongside Pure Genius’ Scientific Advisory Board and spearheaded by Dr. Amy Shah, MD, a double board-certified physician specializing in gut health and women’s wellness, and Dr. Lucia Aronica, PhD, Stanford lecturer, and world-renowned epigenetics researcher, the new Protein + Fiber shot is the solution that makes the two essential nutrients easier to consume in one simple, grab-and-go shot
“Fiber plays a crucial role in digestive, gut, and metabolic health, along with blood sugar regulation and satiety, yet it’s one of the most overlooked nutrients in the American diet,” said Dr. Amy Shah. “At the same time, protein is essential for maintaining muscle, and together they help keep you energized throughout the day and support healthy aging. The problem is that most people treat protein and fiber as two separate projects, and usually manage only one. We formulated this product to offer the first pocket-sized solution that can provide a realistic, repeatable dent in daily fiber and protein shortfalls.”
While protein has become the centerpiece of modern wellness, nutrition experts stress that fiber is one of the most important tools in our longevity toolkit. Both nutrients play vital roles in supporting overall health, however, they rarely exist together in convenient, low-calorie foods. Protein-rich foods like meat and dairy contain little to no fiber, while fiber-rich fruits, vegetables and whole grains typically provide no protein. Existing grab-and-go options often require added sugars, excess calories or extensive preparation, leaving consumers to choose between convenience and balanced nutrition.
“What we eat influences far more than our waistline, it actively programs how our genes behave,” adds Dr. Lucia Aronica. “This is the science of nutritional epigenetics. Fiber is one of the most powerful examples: beyond supporting gut health, it is consistently associated with a lower risk of several major chronic diseases, and emerging research shows it shapes gene expression in ways that affect how we age. Pairing it with high-quality protein in a format people will actually use every day is exactly the kind of simple choice that can add up to something profound over time.”Formulated with a soluble tapioca prebiotic fiber that dissolves clean and sits easy on the stomach, alongside the high-quality protein people know and love from the original Pure Genius Protein shot, Protein + Fiber has just 100 calories with zero sugar and zero fat. Built for the people who have the hardest time hitting nutrition goals in the first place – busy parents, people on GLP-1 medications eating far less, and older adults whose appetite has dropped, it requires no prep and delivers a light, juice-like texture with no grit, chalk or heft, so you can drink it without feeling bloated or full.
“When Dr. Amy joined Pure Genius’ Scientific Advisory Board her first request was to add fiber to the product,” said Robbins. “It took a year to develop a product that met her medical criteria, and it was worth all the effort. Protein + Fiber isn’t just our newest launch, it’s the culmination of a shared vision we had from the beginning and the next chapter of what we have always believed Pure Genius could become – making healthy choices feel easier and convenient so they become everyday wins.”
Available in two delicious new flavors, Mango Banana and Orange Blast, Pure Genius Protein + Fiber retails for $48 for a pack of 12, $3.20 each for 24, and $3 apiece for 36, through the company’s website, PureGeniusProtein.com, as well as Target and Amazon. The product joins Pure Genius’ existing line of high-quality protein shots that have garnered a loyal following since the brand’s market debut
