John Smiddy

How do you build a successful supplement brand on Amazon—and scale it without wasting time, capital, or momentum?

In this episode of the Grownlearn Podcast, host Zorina Dimitrova speaks with John Smiddy, founder of NutraMarketers, about how founders can build, launch, and scale supplement brands across Amazon, direct-to-consumer, and retail channels.

John has helped launch over 200 supplement products, and shares a practical, experience-driven approach to growth—focused on mastering the fundamentals before scaling. From defining your ideal customer and positioning your product correctly to executing a strong launch strategy, this conversation outlines what separates successful brands from those that fail early.

We discuss how the Amazon algorithm evaluates new products, why the first 30 days are critical, and how inventory levels, early reviews, and external traffic influence performance and visibility.

John also breaks down his three-phase growth strategy, guiding brands from launch to Amazon scaling and ultimately to direct-to-consumer expansion. In addition, we explore how AI and Answer Engine Optimization (AEO) are changing SEO, ecommerce discovery, and brand visibility—and what founders need to do to stay competitive.

This episode is particularly relevant for supplement founders, ecommerce entrepreneurs, Amazon FBA sellers, and operators building consumer brands who want to scale with clarity, discipline, and long-term positioning in mind.

John also shares insights into emerging supplement trends, including gut health, postbiotics, nanotechnology-based supplements, and women’s health—highlighting where future growth in the category is likely to come from.
