Dr. David Nazarian, based in Beverly Hills, sought to create a comprehensive dietary supplement to boost immunity for his celebrity clientele during the pandemic. Mattson collaborated with Dr. Nazarian to develop Vitamin MD, a powerful supplement anchored in Vitamin D known for immune support. We conducted brand strategy and naming sessions, designed packaging, and found a copacker for commercialization. The product was finalized in early 2022 and is sold on e-commerce.
