MOSH Raises $13 Million to Scale Brain Health Nutrition Bars in U.S. Grocery Channels

New updates have been reported about MOSH.

MOSH, the brain health nutrition company co-founded by Maria Shriver and Patrick Schwarzenegger, has secured $13 million in Series A funding led by Main Street Advisors to accelerate its transition from niche brand to national grocery player. The capital will support a nationwide Target rollout, expansion across existing banners such as Sprouts, Albertsons, Kroger, and HEB, and the launch of MOSH High Protein, a bar featuring 20 grams of protein, creatine, and the MOSH Signature Brain Blend aimed at both cognitive and physical performance.

The company has surpassed 2,000 U.S. retail doors and expects its retail presence to triple in 2026, driven by faster velocities, more shelf facings, and expanded distribution. Management, including President Jeff Gamsey, is positioning MOSH as a category-defining, durably profitable business, leveraging a supply chain and commercial playbook built over the past two years, while investors such as Main Street Advisors’ Paul Wachter view MOSH as occupying white space in a crowded bar market.

Strategically, MOSH is doubling down on functional differentiation via its High Protein line and its existing bars, which incorporate Cognizin Citicoline along with lion’s mane, ashwagandha, omega-3s, and vitamins B12 and D3 to support focus, memory, and overall brain health. The company is also funding a third research grant in 2026 to study gut biomarkers associated with cognitive decline and Alzheimer’s, aiming to inform early nutritional interventions that could underpin future product innovation and strengthen scientific credibility.

The Series A coincides with a favorable macro backdrop, as the U.S. brain health supplements market is projected to almost double from $3.56 billion in 2024 to $6.80 billion by 2030, while high-protein bars remain one of the fastest-growing bar segments. MOSH’s model also includes a social impact component, with a portion of proceeds supporting The Women’s Alzheimer’s Movement at Cleveland Clinic, where MOSH has already contributed more than $400,000 and funded three research grants, reinforcing brand equity while tapping into rising consumer concern about brain health.
