A Two-part Study of Lembas Edge Evaluating Tolerability and Postprandial Glycemic Control

What this study is about

The goal of part 1 of this clinical trial is to investigate the tolerability of Lembas Edge in healthy adults. The objective of Part 2 of this study is to investigate the efficacy of Lembas Edge on postprandial glycemic control in prediabetic overweight and obese adults. The main questions it aims to answer are: * What is the tolerability of Lembas Edge? * What is the efficacy of Lembas Edge on postprandial glycemic control? Researchers will compare Lembas Edge to placebo to see its effects. Participants will be asked to: * Provide blood samples. * Record their food and beverage intake in Part 2. * Complete a satiety questionnaire in Part 2. * Consume Lembas Edge or placebo as instructed.
