Brief Summary

The purpose of this study is to determine how Emergen-C use can improve quality of life (QoL) in a real-world setting to help consumers and healthcare professionals understand the benefits of taking Emergen-C on a routine or daily basis.

Detailed Description

This will be a randomized, double-blinded, placebo-controlled clinical trial to evaluate the over-time effects of 12-weeks Emergen-C supplementation on QoL parameters in a real-world setting. This study will be entirely decentralized, and participants will not be required to physically attend any on-site visits. All study data will be collected remotely through a study platform using the participant's personal mobile device, tablet or computer. Sufficient participants will be screened to enroll approximately 300 eligible participants (approximately 150 participants per group) and approximately 240 participants are expected to complete the study (approximately 120 participants per group).
