What is it about?
This review examines how catechins, natural compounds found mainly in green tea, affect bone health. Osteoporosis and other bone diseases increase the risk of fractures and disability, especially as people age. Research in cells, animals, and humans shows that catechins—especially epigallocatechin gallate (EGCG)—can protect bone by stimulating bone-building cells (osteoblasts), blocking bone-resorbing cells (osteoclasts), and reducing inflammation. Regular tea drinkers, particularly women, tend to have better bone density, and catechins are also being tested in biomaterials like scaffolds and hydrogels to promote bone regeneration. The evidence points to catechins as a natural way to support bone strength and healing.

Why is it important?
Osteoporosis and fractures are major global health problems, often leading to loss of independence in older adults. Current drugs can have side effects, and prevention is key. This work highlights catechins as a safe, affordable, and widely accessible option to strengthen bones and improve recovery from injury. It also emphasizes future directions like using catechins in advanced biomaterials for regenerative medicine.
Perspectives
What I find most exciting is that a simple habit like drinking green tea could have lasting benefits for bone health. Seeing catechins move from the teacup to cutting-edge biomaterials shows how nutrition and biotechnology can intersect. To me, this research is about more than preventing fractures—it is about finding everyday, sustainable strategies to help people stay active and healthy as they age.
