Delivering the power of astaxanthin

Developed with Doctors◊, designed for you

We know how overwhelming the world of health and wellness products can be. With endless options to choose from, confusing labels to decode, and conflicting advice at every turn, it's hard to know what's actually good for you. We get it — and we believe that when it comes to your health, you deserve the best. Not what's trending, but what actually works for you and your wallet. That's why every product we make is developed in collaboration with our Clinical Advisory Board, a team of leading doctors who work with us to hold every formula to the highest standard.

Clinician's Choice Clinical Advisory Board

We believe every body deserves to run at full strength.

Our Story

In 2019, Daniel Mercer founded Clinician's Choice with a mission: to make clinical-grade supplements accessible to everyone. This wasn't about adding another brand to the market. It was about closing the gap between what the research proves and what actually ends up in the bottle — and raising the bar for quality along the way.

Daniel wanted to create products that actually live up to their claims — delivering powerful, effective doses for everyone, no matter their stage of life, including his own friends and family.

A key part of that mission was our Developed with Doctors◊ initiative. From day one, we've partnered with doctors, researchers, and clinical nutritionists to ensure every Clinician's Choice formula is backed by science, rigorously tested, and designed for real, everyday health needs. Their expert input is woven into every product we create, so you get supplements that meet the highest standards — and actually work.

Our Founder's Story

"After experiencing first-hand what the right nutrients at the right doses did for my own heart health, I realized that most people have no idea how good their body is designed to feel.

I also learned the difference between sub-par supplements and clinical-grade formulas built on potent ingredients at proven dosages. I knew there was an opportunity to do things differently.

With Clinician's Choice, it was important to me that we created products that didn't just meet standards, but exceeded them — using only the best ingredients from the best sources. And to make sure we got it right, I brought in doctors who truly understand the science behind what makes people feel and live their best every single day."
