Synopsis

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

Turmeric, a spice derived from the root of Curcuma longa, contains the active compound curcumin, which has been extensively studied for its anti-inflammatory and antioxidant properties. Scientific interest in turmeric for supporting or treating age-related macular degeneration (AMD) is based on the role of oxidative stress and inflammation in the progression of this eye disease. Laboratory research and animal studies have shown that curcumin can protect retinal cells from oxidative damage and reduce inflammatory processes, which are key factors in the pathogenesis of AMD.

Several in vitro and animal model studies suggest that curcumin may inhibit pathways leading to retinal degeneration. For example, curcumin has been shown to modulate the expression of inflammatory cytokines and reduce the accumulation of reactive oxygen species in retinal tissue. Additionally, some small pilot human studies and reviews propose that curcumin supplementation could be beneficial as part of a broader strategy to protect retinal health.

However, robust clinical trials in humans specifically evaluating turmeric or curcumin for AMD are limited. Most evidence remains preclinical, and issues such as curcumin's poor bioavailability further complicate its therapeutic potential. Therefore, while there is a scientific rationale and some early evidence, the overall level of scientific support remains modest, warranting a rating of 2 out of 5. Turmeric is not established as a primary treatment for AMD, but it continues to be researched for its possible protective effects on the retina.
