About this study

Official title: 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.

Read the 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).

Being tested
Emergen-C Core Super Orange Powder, Placebo

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Emergen-C Core Super Orange PowderDietary supplement

    A dietary supplement powder containing vitamin C, zinc, vitamin B6, vitamin B12, folate, and manganese.

  • PlaceboDietary supplement

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

  25. Adjusted Mean Change From Baseline in Each of the Item Score in the MFI at Weeks 4, 8 and 12: Physically I Feel I am in an Excellent Condition

    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. 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. Each individual item score was ranged from 1 to 5 where lower scores indicated lower level of fatigue. Change from Baseline was calculated by subtracting the individual MFI item score at Baseline from post-Baseline score at indicated timepoints. A negative change from Baseline indicated improvement in fatigue.

    Measured: Baseline, Weeks 4, 8 and 12

  26. Change From Baseline in Additional QoL Parameter at Weeks 4, 8 and 12: Family Support

    Participants answered 2 QoL questions related to Family support domain and indicated how they felt about each statement, on a scale of 1 (yes, that is true) to 5 (no, that is not true). The total domain score was calculated by summation of the scores of individual items and was ranged from 2 to 10 where QoL lower scores indicated better quality of life. Change from Baseline was calculated by subtracting the individual question score at Baseline from post-Baseline score at indicated timepoints. A negative change from Baseline indicated improvement in quality of life.

  27. Change From Baseline in Additional QoL Parameter at Weeks 4, 8 and 12: Resilience

    Participants answered 2 QoL questions related to resilience domain and indicated how they felt about each statement, on a scale of 1 (yes, that is true) to 5 (no, that is not true). The total domain score was calculated by summation of the scores of individual items and was ranged from 2 to 10 where QoL lower scores indicated better quality of life. Change from Baseline was calculated by subtracting the individual question score at Baseline from post-Baseline score at indicated timepoints. A negative change from Baseline indicated improvement in quality of life.

    Measured: Baseline, Weeks 4, 8 and 12

  28. Change From Baseline in Additional QoL Parameter at Weeks 4, 8 and 12: Ability to Relax and Unwind

    Participants answered 2 QoL questions related to 'Ability to relax and unwind' domain and indicated how they felt about each statement, on a scale of 1 (yes, that is true) to 5 (no, that is not true). The total domain score was calculated by summation of the scores of individual items and was ranged from 2 to 10 where QoL lower scores indicated better quality of life. Change from Baseline was calculated by subtracting the individual question score at Baseline from post-Baseline score at indicated timepoints. A negative change from Baseline indicated improvement in quality of life.

    Measured: Baseline, Weeks 4, 8 and 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Emergen-C Core Super Orange Powder in people with Dietary Supplements, run by HALEON at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adjusted Mean Change From Baseline in Multidimensional Fatigue Inventory (MFI) General Fatigue Domain Score at Week 12 (time frame: Baseline and Week 12). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2026; AzTrials last refreshed its copy on 6 Nov 2026.
