About this study

Official title: The Effects of Resistance Training and a Sarmentosin - L-theanine Supplement on Perimenopausal Symptoms and Musculoskeletal Health: A Randomised Controlled Trial

The aim of this clinical trial is to determine if resistance training and a newly developed plant-based nutritional supplement can improve the symptoms and musculoskeletal health of perimenopausal women.

The main questions it aims to evaluate are:

Read more
  1. Can resistance training and the nutritional supplement - both independently and in combination - improve perimenopausal symptoms (e.g. cognition, mood, sleep) and musculoskeletal outcomes (e.g. strength, muscle mass)?
  2. What are the acute effects of the nutritional supplement on cognitive function and mood in perimenopausal women, and is this response altered following long-term intake (12 weeks)?
  3. What mechanisms may be contributing to the results?

Participants will be split into four groups to allow the researchers to answer the above questions. These are:

  1. The nutritional supplement + resistance training
  2. The nutritional supplement only
  3. The placebo supplement (A look alike capsule that contains no active ingredients) and resistance training
  4. The Placebo supplement only.

Participants will:

  • Take their allocated supplement daily and perform home-based strength exercise 3 times per week (for exercise groups), for 12 weeks.
  • Attend the laboratory at the beginning and end of the 12 weeks to assess cognitive function and mood following acute intake of the supplement.
  • Attend the laboratory every 4 weeks during the 12 week period, for assessment of cognitive function, symptom severity and muscle health.
  • Provide a blood sample at each visit for assessment of mechanistic pathways.

Questions about this trial

What is this clinical trial studying?

A study testing Sarmentosin - L- theanine and Resistance Training in people with Perimenopause and Menopause, run by Leeds Beckett University at 1 site in United Kingdom.

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 12 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 27 Mar 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 Kingdom. 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 Harriet Cannell (+447805576688, H.cannell@leedsbeckett.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Depressive Symptom Score at week 4 (time frame: Week 4). 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 27 Mar 2026.
