What this trial studies

This clinical trial evaluates how a combination of supplements affects sleep quality and stress levels in healthy adults aged 18 to 50. Participants will receive various active supplement combinations, including Ashwagandha, Rhodiola rosea, magnesium threonate, L-theanine, and apigenin, or placebos. The study aims to determine the efficacy of these supplements in improving sleep and reducing stress through a structured intervention. Participants will be monitored for their responses to the supplements over the course of the trial.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 50 with a BMI between 18.5 and 29.9 who are physically active.

Not a fit: Patients with known allergies to any of the investigational products or those not meeting the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a natural approach to improving sleep quality and reducing stress for healthy adults.

How similar studies have performed: While there have been studies on individual supplements for stress and sleep, this specific combination approach is relatively novel and has not been extensively tested.
