A Study Evaluating Quality of Life Parameters Following Use of Emergen-C

A Real-World Evidence Study Evaluating Quality of Life Parameters Following Use of Emergen-C

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.

Study Overview

• Status: Completed
• Conditions: Dietary Supplements
• Intervention / Treatment: Dietary supplement: Emergen-C Core Super Orange Powder; Dietary supplement: Placebo

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).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Emergen-C Core Super Orange Powder (Test Product); Participants will be instructed to take the study product as per label instructions. Participants will consume one sachet of Emergen-C Core Super Orange Powder stirred in 4-6 ounces of water, orally, once daily for up to 12 weeks.	Dietary supplement: Emergen-C Core Super Orange Powder; A dietary supplement powder containing vitamin C, zinc, vitamin B6, vitamin B12, folate, and manganese.
Placebo Comparator: Placebo (Reference Product); Participants will be instructed to take the study product as per label instructions. Participants will consume one sachet of placebo stirred in 4-6 ounces of water, orally, once daily for up to 12 weeks.	Dietary supplement: Placebo; To ensure proper blinding, the placebo was formulated to be indistinguishable from Emergen-C in taste, appearance, and other sensory characteristics. The placebo therefore contained fructose, and the electrolytes potassium, magnesium, calcium, and sodium.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adjusted Mean Change From Baseline in Multidimensional Fatigue Inventory (MFI) General Fatigue Domain Score at Week 12	The MFI was a 20-item scale designed to evaluate five dimensions of fatigue: general fatigue, physical fatigue, reduced motivation, reduced activity, and mental fatigue. General fatigue domain had 4 items. Participants answered how they felt about each item, on a scale of 1 (yes, that is true) to 5 (no, that is not true). Positively phrased items were reversely scored and negatively phrased items were scored at face value. The total domain score was calculated by summation of the scores of individual items and ranged from 4 to 20 where lower scores indicated lower level of fatigue. Change from Baseline was calculated by subtracting the Baseline score from score at Week 12. A negative change from Baseline indicated improvement in fatigue.	Baseline and Week 12
