Effects of Sabroxy® Supplementation on Insulin Resistance and Cognitive Function in Adults With Mild Cognitive Impairment and Insulin Resistance

Mild cognitive impairment (MCI) often occurs alongside metabolic disturbances such as insulin resistance and chronic inflammation, which are recognized contributors to neurodegenerative risk. Sabroxy® is a standardized extract of Oroxylum indicum bark, traditionally used in Ayurvedic medicine, and has demonstrated antioxidant, neuroprotective, and glucose-regulatory properties in preclinical studies. This study aims to evaluate the potential of Sabroxy® supplementation to improve both metabolic and cognitive outcomes in adults with MCI and insulin resistance. The trial follows a randomized, double-blind, placebo-controlled design, with 120 eligible participants randomized in a 1:1 ratio to receive either Sabroxy® (250 mg combined with 5 mg BioPerine®) or placebo once daily for 8 weeks. The primary objective is to assess the effect of Sabroxy® on insulin resistance as measured by HOMA-IR. Secondary objectives include assessing cognitive function improvements (using Immediate Word Recall, Numeric Working Memory, CFQ, and MoCA tests), as well as evaluating changes in biochemical markers related to neuronal health (BDNF, p-Tau/Aβ ratio) and inflammation (hs-CRP). Safety assessments include adverse event monitoring, vital signs, and standard clinical laboratory evaluations throughout the study. All study procedures are conducted at the San Francisco Research Institute (USA) in accordance with the Declaration of Helsinki, ICH-GCP guidelines, and 21 CFR Part 312 (where applicable). The outcomes from this study are expected to contribute evidence on the dual role of Sabroxy® in improving glucose tolerance and supporting cognitive function in individuals exhibiting early metabolic and neurocognitive dysfunctions.
