My name is Denise John. I’ve been researching and writing for prominent dietary supplement companies for 15 years, and I’m here to share tips on how to choose a quality supplement—since I’ve been involved in the production, research and development, and marketing sides of the dietary supplement world and know the key things to look out for.

I’m really passionate about this topic—and most science topics really—because as more people, including my friends and family members, are starting to incorporate supplements into their diets, I’m seeing how important it is to have foundational understanding of supplements. This way, you'll feel good (and confident) about how you’re supporting your health and spending your dollars.
