When our clinic suggests Thorne
We don't start with a brand. A Holistic Health Partners nurse starts with your goals, what you already take and where you are on your health journey, then suggests what fits. Thorne is often a good fit when:
“I never start with a brand. I start with the person in front of me: their goals, what they already take, and where they are on their health journey. Every brand in the Brand Zone has earned its place, and I suggest whichever one makes the most sense for that client. Our job is to help people live their best lives.”

Every Brand Zone brand is checked against the same standards. Here is how Thorne measures up.
Made in Thorne's own NSF-certified facility in Summerville, South Carolina, with an A rating from Australia's Therapeutic Goods Administration.
Four rounds of testing in two in-house labs, from raw-material purity to shelf life, plus independent batch testing by NSF on NSF Certified for Sport products.
Holistic Health Partners nurses suggest Thorne when it fits a client's goals, and help clients choose in free product consultations.

Questions about Thorne
What is Thorne known for?
Thorne is known for making its own supplements at its campus in Summerville, South Carolina, and for its NSF Certified for Sport line of more than 20 products. Popular Thorne formulas at Covenant Health Products include Creatine, Basic Nutrients 2/Day and Magnesium Bisglycinate.
Is Thorne a trustworthy supplement brand?
Our clinic thinks so. Thorne manufactures its own products in an NSF-certified facility, runs four rounds of testing in two in-house labs, and holds an A rating from Australia's Therapeutic Goods Administration. Holistic Health Partners nurses suggest Thorne when it fits a client's needs.
How does Thorne test its supplements?
Thorne runs four rounds of testing, from checking the purity of raw materials to confirming the shelf life of finished formulas, and screens raw materials for contaminants. Products with the NSF Certified for Sport mark are also tested batch by batch by NSF, an independent organization.
Where are Thorne supplements made?
Thorne makes its supplements in the United States, at its own campus in Summerville, South Carolina, where the company is also headquartered. Making products in-house means one company is responsible for each formula from raw material to finished bottle.
Why buy Thorne from Covenant Health Products?
Every Thorne order at Covenant Health Products comes with access to Holistic Health Partners nurses, who offer free product consultations, and clinic members get Patient Pricing. We carry Thorne alongside nine other practitioner brands, so a nurse can suggest what truly fits instead of steering you toward one line.
How does Thorne compare with Pure Encapsulations?
Both are practitioner-trusted brands our clinic uses. Thorne stands out for manufacturing in its own facility and for its NSF Certified for Sport line, which suits athletes who are drug tested. Pure Encapsulations focuses on hypoallergenic formulas made without common allergens. Which fits depends on your needs.
Can I get help choosing Thorne products?
Yes. Holistic Health Partners offers a free product consultation. A nurse will look at your goals and what you already take, and help you decide which Thorne products, if any, fit. There is no cost and no obligation to buy.
