Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Curcumin, the main active compound in turmeric, has been investigated for its potential role in supporting bone healing and repair. Several preclinical studies using animal models have demonstrated that curcumin may promote fracture healing by modulating inflammation, reducing oxidative stress, and supporting the differentiation and activity of osteoblasts (bone-forming cells). For instance, studies have shown that curcumin can increase the expression of growth factors and signaling molecules involved in bone regeneration, such as bone morphogenetic proteins (BMPs), and may decrease the activity of osteoclasts, which break down bone tissue.

However, the bulk of evidence comes from laboratory and animal studies, with very limited clinical research in humans. There are currently no large-scale, high-quality randomized controlled trials demonstrating that curcumin supplementation significantly accelerates bone healing or improves outcomes in people with broken bones. Some smaller studies suggest curcumin may help reduce inflammation and pain associated with bone injury, but these findings are preliminary.

In summary, while there is a scientific rationale for curcumin’s possible benefits on bone healing—mainly due to its anti-inflammatory and antioxidant properties—direct evidence in humans is weak. The current evidence rating is 2 out of 5, reflecting promising preclinical data but insufficient clinical validation. More robust human studies are needed before curcumin can be recommended as a standard adjunct therapy for broken bones.
