Maqui and Chronic Kidney Disease: A Narrative Review on the Potential Nephroprotective Role of Anthocyanins.

Chronic kidney disease (CKD) is a progressive pathology, with high global prevalence, associated with inflammation and oxidative stress. Given the limited capacity of conventional treatments to reverse renal damage, complementary alternatives have emerged such as supplementation with anthocyanins from maqui (), known for their antioxidant and anti-inflammatory properties. This review analyzes the evidence for their impact on CKD progression. A narrative review of the experimental literature regarding maqui anthocyanins, their bioavailability, and their effects on oxidative stress, inflammation, and CKD to January 2025 was conducted. Articles without peer review or without a focus on were excluded, guaranteeing an updated compilation on its nephroprotective potential. : Anthocyanins have shown benefits in reducing oxidative stress, inflammation, and glycemia regulation. Preclinical studies suggest improvements in renal function as well as less fibrosis. Human trials indicate positive effects on metabolism, although evidence in CKD patients is limited. Bioavailability remains a challenge to optimizing efficacy. : Maqui is a promising source of anthocyanins, with nephroprotective potential. However, robust clinical studies are required to determine its safety, optimal dose, and long-term impact in CKD. Its incorporation into evidence-based therapeutic strategies could offer an innovative approach in the management of this disease. More clinical studies are needed to validate the preclinical findings and optimize the therapeutic use of maqui in CKD.
