Sabroxy® for lowering insulin resistance and improving memory in adults with mild cognitive impairment

Official title: An 8-week Study Evaluating the Effects of a Dietary Supplement (Sabroxy®) on Insulin Resistance and Cognitive Function in Subjects With Mild Cognitive Impairment and Insulin Resistance

Run by SF Research Institute, Inc. · NCT07220694 · Data updated 2026-11-12

This 8-week, double-blind, placebo-controlled test will see if taking Sabroxy® once daily lowers insulin resistance and improves thinking and memory in adults aged 40–80 with mild cognitive impairment and elevated fasting glucose or HOMA-IR.

Is this trial a fit for you?

Likely a good fit

Adults aged 40–80 who are non-smokers, in generally good health, have MoCA < 26, fasting glucose 100–135 mg/dL and a HOMA-IR between 2.0 and <4.0, and who are not taking medications or supplements that affect glucose tolerance are ideal candidates.

Probably not a fit

People with normal glucose regulation or HOMA-IR outside the specified range, those taking glucose-altering medications or supplements, pregnant or breastfeeding individuals, or those with significant unstable medical conditions are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind, placebo-controlled trial will enroll 120 non-smoking adults (age 40–80) with mild cognitive impairment (MoCA < 26) and insulin resistance (fasting glucose 100–135 mg/dL, HOMA-IR ≥ 2.0 to < 4.0). Participants are randomized 1:1 to receive Sabroxy® (250 mg with 5 mg BioPerine®) or matching placebo once daily for 8 weeks. The primary outcome is change in insulin resistance measured by HOMA-IR from baseline to Week 8, with secondary outcomes including tests of memory and working memory, MoCA, inflammatory and neuronal biomarkers (hs-CRP, BDNF, p-Tau/Aβ ratio), and safety monitoring. All procedures are conducted at the San Francisco Research Institute under standard ethical and regulatory guidelines.

Why it matters

Potential benefit: If successful, Sabroxy® could provide a well-tolerated oral supplement that reduces insulin resistance and may modestly improve cognitive performance in adults with MCI and metabolic dysregulation.

How similar studies have gone: Preclinical studies of Oroxylum indicum extracts show antioxidant, neuroprotective, and glucose-regulatory effects, but clinical evidence for Sabroxy® in humans with MCI and insulin resistance is limited and this application is relatively novel.
