When in 1946 Solange Le Hir, a nurse chose to use fresh brewer's yeast as a dietary supplement, it originated the creation of the Carrare laboratories.
From 1994, the innovative Bioprotus range was launched. It is based on fibers and lactic ferments.
In 2004, Carrare took over Dietactiv, a company specialised in phytotherapy.
In 2015 Bioprotus innovates again with a dietary supplement for mouth and teeth.
