About Klaire Labs > SFI Health

Klaire Labs® is now SFI Health™

Klaire Labs® has been part of the SFI Health family for many years leading the way in efficacy, safety, quality, and trusted by healthcare professionals to deliver better outcomes for their patients. SFI Health will be transitioning the Klaire Labs® brand to the SFI Health brand, which will become more prominent on their packaging and materials. While SFI Health might be changing the way things look, you can be sure their commitment to consistency and quality will be as strong as always.

The Brand you Know and Love is Changing.

Rest assured that the ingredients and formulation remain the same. If you’re looking for something in particular, and can’t find it, it’s likely because the name changed. We’ll update the labels and names on our product pages


Claire Farr founded Klaire Labs in 1969. Claire had a number of allergies and sensitivities and realized that it wasn’t just chemicals, but certain foods that were factors to her sensitivities.

The supplements she took to alleviate her symptoms were made with preservatives, additives, colorings, flavorings and other allergens. She also realized that most supplements at the time were in tablet form and due to her sensitive stomach, she needed her supplements in a different form.

She started with single ingredient formulations, using only pharmaceutical grade raw ingredient for maximum purity and bio-availability. All vitamins and supplements Claire created were made to be free of allergens, excipients, flavorings, colorings and additives.

Klaire Labs started as a medical necessity for Claire and has since become a trusted brand for many practitioners and offers hundreds of products to choose from. Klaire Labs continue their tradition of using ingredients that are as naturally based as possible to make clean and pharmaceutical grade formulations for their nutritional supplements.

In 2013, ProThera and Complementary Prescriptions were unified under Klaire Labs. Klaire Labs is a cGMP manufacturing facility located in Reno, Nevada.
