About this study

Official title: A Randomised, Double-Blind, Placebo-Controlled Trial Investigating the Effects of Omega-3 Fatty Acids on Memory and Cognition in Perimenopausal and Menopausal Women

The goal of this clinical trial is to learn if daily omega-3 supplementation improves memory and cognitive function in perimenopausal and menopausal women aged 40-60 years. It will also assess whether omega-3 supplements influence menopausal symptoms, stress levels, and sleep patterns.

The main questions it aims to answer are:

  1. -Does omega-3 supplementation improve memory and cognitive performance?
  2. - Does omega-3 supplementation affect menopausal symptoms, stress, and perceived memory changes? 3- Are there any differences in sleep patterns during supplementation?

Researchers will compare omega-3 supplements to a placebo to see if omega-3 improves memory and cognition.

What participants receive

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

  • A Randomised, Double-Blind, Placebo-Controlled Trial Investigating the Effects of Algae Omega-3 Fatty Acids on Memory and Cognition in Perimenopausal and Menopausal WomenDietary supplement

    The intervention consists of daily supplementation with a DHA-dominant omega-3 algae based formulation (approximately 950 mg DHA and 350 mg EPA) for 12 weeks. This dose (>1 g/day) is selected based on evidence suggesting higher omega-3 intake is required to influence cognitive outcomes.

    The study targets perimenopausal and menopausal women aged 40-60 years, a population experiencing hormonally related cognitive changes.

    The comparator is a matched placebo (high oleic refined sunflower oil, 1000 mg), selected for its inert fatty acid profile and absence of DHA/EPA.

    Capsules are identical in appearance and dosing to maintain blinding. The DHA-focused formulation, specific population, and combined cognitive, questionnaire, and sleep assessments distinguish this intervention from other omega-3 studies.

What is being measured

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

  1. Verbal Memory

    Change in Memory scores from baseline to post-intervention, Rey Auditory Verbal Learning Test (RAVLT)

    Measured: From baseline to completion, up to 31 days

  2. Working memory

    Change in memory from baseline to completion using the Digit Span Test

    Measured: From baseline to completion, up to 31 days

  3. Verbal Adaptation

    Change in verbal adaptation from baseline to completion using the Stroop Test

    Measured: From baseline to completion, up to 31 days

Secondary outcomes (5)
  1. Change in menopausal symptoms (quality of life)

    Change in menopausal symptoms assessed using the Menopause-Specific Quality of Life (MENQOL) questionnaire.

    Measured: From baseline to completion, up to 31 days

  2. Change in subjective memory function

    Change in self-reported memory lapses measured using the Prospective and Retrospective Memory Questionnaire (PRMQ).

    Measured: From baseline to completion, up to 31 days

  3. Dietary patterns

    Dietary patterns assessed using a short Food Frequency Questionnaire to account for habitual nutrient intake that may influence outcomes.

    Measured: From baseline to completion, up to 31 days

  4. Sleep patterns

    Change in sleep duration, sleep quality, and number of night-time awakenings, recorded using daily sleep diaries over 7 consecutive days.

    Measured: Baseline (Week 0; 7-day recording period prior to intervention)End of intervention (Week 12; 7-day recording period)

  5. Stress levels

    Change in self-reported stress levels are integrated in self-reported questionnaire

    Measured: From baseline to completion, up to 31 days

Questions about this trial

What is this clinical trial studying?

A study of Menopause, run by St. Mary's University, Twickenham 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 6 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: under way, not looking for participants, as of the sponsor's last update on 10 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 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?

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?

Verbal Memory (time frame: From baseline to completion, up to 31 days). The study lists 3 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 10 Sep 2026.
