Why Bone Loss Accelerates With Aging: The Gut–Bone Connectio

Bone loss doesn’t start when fractures happen — it begins years earlier. In this episode, we explore how bone aging accelerates during menopause and the emerging role of the gut microbiome as a driver of skeletal decline. Dr. Kara Fitzgerald speaks with research scientists from Sōlaria biō, the company behind Bōndia, about their work studying plant-derived microbes, microbial synergies, and the connections between gut health, inflammation, and bone loss in peri- and postmenopausal women. We also review findings from a randomized, placebo-controlled clinical trial examining a microbiome-based intervention for bone health — and discuss why bone loss may need to be addressed earlier, systemically, and beyond hormones alone.
