Safe-Age Study: A Safety and Tolerability Study of a Nutritional Supplement in Healthy Older Adults

This is an open-label, single-arm interventional study designed to assess the safety and tolerability of the nutritional supplement Youniqor in healthy older adults. The study will enroll men and women aged 60 to 80 years who meet predefined eligibility criteria and provide written informed consent.

Participants will receive daily oral supplementation with Youniqor for a period of 8 weeks. Safety will be monitored throughout the study through the assessment of adverse events, vital signs, clinical laboratory parameters, and electrocardiograms at predefined time points.

The study is conducted at clinical research sites in India under the oversight of an independent ethics committee and in accordance with applicable regulatory and ethical guidelines. The results of this study are intended to support the characterization of the safety profile of Youniqor in healthy older adults.
