Navigating Nutritional Science and Research Rigor in Supplements

On this episode of the Modern Retail Podcast, co-hosts Gabriella Barkho and Melissa Daniels break down Dick's Sporting Goods’ $2.4 billion acquisition of Foot Locker. They also discuss the debut of the Girl Scouts’ newest cookie, the Exploremores, and how the organization has evolved from door-to-door sales to SMS-powered marketing.

For this week’s featured segment, Daniels sits down with AG1 CEO Kat Cole. The green supplement giant pulled in $600 million in revenue last year with a single SKU, but 2025 has brought major growth: a reformulated powder called NextGen with new flavors, the launch of its first sleep product AGZ, and a wholesale partnership with Costco. Cole shares how AG1 invests in R&D — from triple-blind testing to scaling supply chains — and why adding more probiotics or B vitamins comes with big costs.
