The Solarea breakthrough came from the combined efforts of the company’s co-founders who established a link between the discovery of an untapped source of microorganisms with probiotic potential in healthy foods, and their applications in inflammatory processes including the gut-musculoskeletal axis.

The first application aims to address the metabolic processes of osteopenia and osteoporosis in postmenopausal women where diet alone is not sufficient to maintain a healthy skeleton and natural alternatives are desired over conventional pharmaceuticals
