Mosh is a brain health nutrition brand co-founded by Maria Shriver — journalist, author, former First Lady of California, and Alzheimer’s advocate — and entrepreneur JP Twomey. Launched in 2021, Mosh produces protein bars formulated with cognitive-health ingredients including lion’s mane mushroom, collagen, B12, and MCT oil, targeting consumers who want to support brain health through everyday nutrition.
Who Is the Owner of Mosh?
Mosh is co-owned by its co-founders Maria Shriver and JP Twomey. Maria Shriver is the daughter of Sargent Shriver and Eunice Kennedy Shriver (JFK’s sister), and a prominent figure in American public life as a journalist (NBC News), author, and Alzheimer’s disease advocate following her father’s diagnosis. Twomey is the entrepreneurial and operational co-founder who handles the business side. The company is privately held with no public shareholders. Mosh has received investment from strategic partners and venture backers, though the founders retain ownership control.
The Brain Health Mission
Mosh’s founding is deeply personal for Maria Shriver. Her father Sargent Shriver suffered from Alzheimer’s disease, and her uncle President John F. Kennedy’s family has a long history of advocacy for health causes. Shriver has channeled this personal connection into Mosh — a brand that donates a portion of proceeds to Alzheimer’s research. In a crowded protein bar market, Mosh differentiates itself not just through ingredients but through its specific “brain health” positioning at a time when cognitive wellness is a rapidly growing consumer category.
Market and Competition
Mosh competes in the functional nutrition bar space alongside brands like RXBar (owned by Kellogg), CLIF Bar (Nestlé), and Kind Bars (Mars). What distinguishes Mosh is its celebrity-driven brand narrative and its specific cognitive-health ingredient stack. The brand has been sold through major retail channels including Amazon, Target, and specialty health retailers, leveraging Maria Shriver’s substantial public platform to build awareness without massive traditional advertising spend.
