About this study

Official title: TONE UP: Daily Upgrade Trial: Tone, Oxygenation, Neuromood, Energy - Upgrade Evaluation

This study evaluates the acute and chronic effects of an essential amino acid supplement (Daily Upgrade EAA+) on metabolomics, amino acid kinetics, metabolic rate, body composition in active adult women. The study consists of an acute randomized double-blind crossover phase comparing EAA+, whey protein isolate, and placebo before high-intensity interval training (HIIT), and a chronic randomized double-blind parallel-arm phase evaluating 3 weeks of EAA+ or placebo supplementation combined with twice-weekly HIIT.

Read the detailed description

The trial includes an acute crossover phase and a chronic parallel-group phase. In the acute phase, participants complete three randomized laboratory visits during which they consume Daily Upgrade EAA+, whey protein isolate, or a non-caloric placebo prior to a standardized high-intensity interval training (HIIT) session. Metabolomic responses, amino acid kinetics, metabolic outcomes are assessed before and after exercise.

In the chronic phase, participants are randomized to consume Daily Upgrade EAA+ or placebo daily for three weeks while completing supervised HIIT sessions twice per week. Outcomes assessed before and after the intervention include body composition, exercise performance, fluid balance, and gastrointestinal symptoms.

What is being measured

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

  1. Essential Amino Acid Kinetics

    Area under the curve for metabolomic responses

    Measured: Baseline, 30, 60, and 90 minutes following supplementation during acute visits.

  2. Substrate Oxidation

    Measured: Before (0 min) and after (30, 60, 90 min) one session of high intensity interval training

Secondary outcomes (3)
  1. Lean Body Mass

    Dual energy x-ray absorptiometry-derived lean soft tissue

    Measured: Baseline and week 4

  2. Muscle size

    Muscle cross sectional area derived from peripheral quantitative computed tomography

    Measured: Baseline week 4

  3. Fluid Kinetics

    Total body water

    Measured: Baseline, week 1, week 2, week 3, week 4

Model description
This study incorporates two randomized intervention components within a single protocol. The primary trial is a double-blind, parallel-group study in which participants are randomized to receive either Daily Upgrade EAA+ or placebo during a 3-week supervised high-intensity interval training (HIIT) intervention. Embedded within the overall trial is an acute, randomized, double-blind crossover substudy in which a subset of participants completes three experimental visits and receives Daily Upgrade EAA+, whey protein isolate, and placebo in randomized order to evaluate acute metabolomic, metabolic, and physiological responses before and after HIIT.

Questions about this trial

What is this clinical trial studying?

A study testing Essential Amino Acid+, High intensity Interval Training and No Exercise in people with Healthy Women, run by University of North Carolina, Chapel Hill 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 8 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 3 Sep 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Abbie Smith-Ryan, PhD (919-962-2574, abbiesmith@unc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Essential Amino Acid Kinetics (time frame: Baseline, 30, 60, and 90 minutes following supplementation during acute visits.). The study lists 2 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 3 Sep 2026.
