Aonic enters protein market with clean-label shake, no artificial sweeteners

Aonic has entered the ready-to-drink protein market with a shake built around a simple pitch: 32 grams of complete protein, 5 grams of fiber, 160 calories and no artificial sweeteners. The San Francisco company launched Aonic Fuel on April 30 in Rich Chocolate and Smooth Vanilla, putting a shelf-stable, lactose-free option into a category where many drinks still depend on heavy sweetness and texture systems to win repeat buyers.

The real test is whether “no artificial sweeteners” is a meaningful edge or just another clean-label signal in a crowded aisle. Aonic is betting that the answer is yes, and it is backing that bet with a formulation that uses lactose-free milk protein for a full amino-acid profile, comes in 11-ounce cans and is marketed as non-GMO. The company also says the drink has 0 grams of added sugar, which places it squarely in the protein-beverage lane but with a simpler ingredient story than many incumbents.

Aonic also moved to frame the launch as more than a flavor-and-macros play. It named Dr. Jason Mitchell, N.D. as chief medical advisor and chairman of its medical advisory board, giving the brand a scientific face as it pushes into higher-frequency beverage use. Aonic describes Mitchell as a board-certified naturopathic doctor with nearly 30 years of experience in formulation science and nutrition innovation, and says he has helped bring nearly 1,000 wellness products and dietary supplements to market.

Mitchell said the overuse of artificial sweeteners is one of the most underestimated issues in modern nutrition, and that Aonic Fuel was built without them because long-term wellness is better supported by more thoughtful ingredient choices. That kind of language matters in a protein market where consumers have become more skeptical about what goes into shakes as much as what comes out of them in terms of grams and calories.

The launch also fits into Aonic’s broader functional-nutrition push. The company’s earlier U.S. debut in November 2025 introduced Aonic Complete and Aonic Revive and positioned the brand around “modern malnutrition” and science-backed nutrition. Fuel extends that strategy into a larger beverage occasion, aiming beyond the gym and into everyday use.

That timing looks shrewd. One market estimate put the global ready-to-drink protein beverage market at about $1.96 billion in 2025, with growth projected to roughly $3.06 billion by 2031. At the same time, Consumer Reports said in October 2025 that more than two-thirds of 23 tested protein powders and shakes contained more lead in a single serving than its experts considered safe for a day. Against that backdrop, Aonic’s commercial credibility will hinge on whether its cleaner label, medical-advisor messaging and conservative flavor lineup can deliver the taste and trust consumers expect without leaning on the sweetener systems that are now under pressure.
