Klaire Labs


Pioneer in professional grade nutrition

Setting quality standards since 1969

Borne of a personal medical need, Claire Farr founded Klaire Labs on the premise that clean, pharmaceutical grade formulations should be the model for nutritional supplements. The medical community took notice, and Klaire Labs became the standard bearer of purity, potency, and performance.

The Beginning

In 2013, the entrepreneurs of Soho Flordis International (SFI) saw in Klaire Labs a shared vision and set out to unify sister brands ProThera and Complementary Prescriptions under the founding principles of Claire Farr herself. Toward that end, SFI made an immense investment in a purpose-built cGMP manufacturing plant in Reno.  As we transferred each product in the portfolio to the new Klaire Labs facility, we evaluated the formulations through the exacting Klaire quality lens and unified under the Klaire Labs brand umbrella and philosophy.
