About the Nutrient Store

Not all vitamins and supplements are created equal. So how do you know which ones to trust?

The Riordan Clinic Nutrient Store has provided high-quality vitamin and supplement products for our patients and customers for more than three decades. What started as a way for patients to easily access the vitamins, supplements, and nutrients that were being prescribed at their appointments has grown to a global reach through our online store.

Here are a few things that set the Riordan Clinic Nutrient Store apart:

  • All vitamin and supplement products are chosen specifically by the Riordan Clinic team of doctors and providers based on quality, purity, consistency, and effective dosing.

  • Our most trusted vitamins and supplements have been given the Riordan Clinic name. Currently, we offer 33 products in our line with more coming soon.

  • Purchasing your products directly from the doctors who have recommended them ensures that you are getting the correct dosage, ingredients, and brand.

  • The Nutrient Store provides access to over 300 pharmaceutical grade vitamins and supplements from more than 50 manufacturers.

  • All products have been independently tested by third-party laboratories to assure that what is listed in the ingredients is exactly what is in the end product.
