🏷️ Klaire Labs / SFI Health: hypoallergenic supplements for sensitive people
A brand that literally "grew" out of allergology: the story of nurse Claire Farr since 1969
Klaire Labs is a hypoallergenic supplement brand now developed within SFI Health. Its hallmark is attention to ingredient purity for sensitive people.
Who they are
Klaire Labs is an American manufacturer of hypoallergenic supplements, founded in 1969 by registered nurse Claire Farr. In mid-life she developed severe allergies and environmental sensitivities. Standard supplements with fillers and synthetic ingredients did not suit her, so she began creating her own clean formulas at home in Carlsbad, California.
Claire was among the first to buy pharmaceutical-grade raw materials, avoiding common allergens and extra ingredients. Her products caught the attention of the medical community, including well-known advocates of complementary medicine. A personal problem grew into a pioneering line of clean, well-studied probiotic strains — today the brand is part of the SFI Health group and remains the leading professionally distributed probiotic line in the US.
