First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study tests whether taking peanut skin extract (SugarLock) or white kidney bean extract before a meal can reduce or delay blood sugar spikes in healthy adults. Participants take capsules with water and have their glucose levels monitored continuously for three hours after eating. The goal is to see if these supplements could help manage post-meal blood sugar.

- What this could lead to
- If effective, these supplements could offer a natural way to manage blood sugar spikes after meals, potentially helping people without diabetes maintain better glucose control.
- What could go wrong
