This study evaluates changes in hunger perception and body composition-related measures following daily use of a commercially available dietary supplement formulated to support leptin-related metabolic signaling. Adult participants will self-administer the supplement for 12 weeks and complete periodic self-reported assessments related to appetite, hunger, and weight-related outcomes. Participants serve as their own control, with comparisons made between baseline and follow-up measurements. The study is designed to generate preliminary, real-world evidence regarding supplement use in a general wellness context.

Leptin is a hormone involved in appetite regulation and satiety signaling. Dysregulation of leptin signaling has been associated with altered hunger perception and weight management challenges. While diet and physical activity are commonly emphasized in weight optimization strategies, hormonal contributors such as leptin are less frequently evaluated in real-world consumer settings.

This single-arm, observational study is designed to explore changes in hunger perception and weight-related outcomes associated with daily use of the Leptin Balance Formula, a commercially available dietary supplement containing African mango seed extract, chromium picolinate, Ceylon cinnamon, and alpha lipoic acid. Participants will use the product for 12 weeks and complete electronic surveys and self-reported measurements at baseline and designated follow-up time points.

The study is conducted under Efforia's Minimal Risk Umbrella Protocol and is intended as a signal-detection study to inform future, more controlled research designs. The study does not diagnose, treat, or prevent disease and is limited to general health and wellness outcomes.
