Golan Cohen
Co-founder and CMO, D3X
I lead marketing and affiliate partnerships at D3X. My focus is helping creators, coaches, and customers understand why vitamin D matters and giving them clear, reliable information they can confidently share.
Why I started D3X
Most people have heard of vitamin D, but far fewer understand what it does, why low levels are so common, or what separates one supplement from another. I saw a communication problem: important research existed, but it was not reaching people in a way that felt clear, relevant, or actionable.
My background in Computer Information Systems taught me to think about how information, people, and technology connect. I bring that same approach to marketing at D3X. Rather than simply promoting a product, I work on building the education and systems that move information clearly from the research, to creators and coaches, to the people who trust them.
A large part of my work is building our affiliate and coach network. I help partners understand the research behind vitamin D, how D3X is formulated, and how to talk about it accurately in their own voice. I believe good marketing is not about making the biggest claim. It is about making something important understandable enough that people care and act on it.
What I write about
On the D3X blog, I write about vitamin D awareness, supplement marketing, and the role creators can play in making health information easier to understand. My goal is to turn research into clear, practical information that people can use and share.
