Solabia Introduces Bioavailable Mineral Salts

October 7, 2013

The core molecule of Solabia’s mineral salts is pidolic acid or L-PCA (L-pyrrolidone carboxylic acid). This molecule is present in different organs and tissues of the human body (skin, brain, blood cells and biological fluids, etc.) where it plays a crucial role. 

Natural and well tolerated, pidolic acid is a: precursor of gamma-amino butyric acid (GABA), a molecule involved in adrenergic regulation, pidolic acid promotes relaxation; precursor of ketoglutaric acid, an intermediate in the Krebs cycle which forms the hub of carbohydrate, lipid and amino acid metabolism of almost all cells; precursor of glutathione in the gamma glutamyl cycle, pidolic acid protects the body against reactive oxygen species (ROS).

Pidolic acid is used in the preparation of pharmaceutical proprietary products and in food supplements in the form of calcium, magnesium, zinc, iron, manganese and potassium salts, named pidolates.

Pidolic acid facilitates the transport and improves the bioavailability of the mineral. Numerous studies clarify the role of pidolic acid and its pidolates as an active physiological carrier.

This organic carrier strongly influences the assimilation of the mineral by the organism and the use of the pidolic acid as carrier contributes to make pidolates  highly available mineral forms.

Pidolates represent an example of complementarity between a mineral and its carrier. Manufactured as powder, the pidolates can be used indifferently in the production of tablets, capsules, sachets but also for soft capsules. Highly soluble, pidolates are particularly suitable for drink formulations or other liquid forms. For more information:
