Effect of Sage Extract Supplementation on Cognitive Function in Middle-Aged Men and Women

August 5, 2026 updated by: ESM Technologies, LLC

Effect of SageXtra Supplementation on Cognitive Function in Middle-Aged Men and Women

Sage (Salvia officinalis) has been reported to have antioxidant, anti-inflammatory, and neuroprotective properties. Several studies indicate that sage supplementation can improve cognitive function. However, more research is needed. The purpose of this study is to examine how sage supplementation affects cognitive function and reaction times in middle-aged men and women.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

To evaluate the effects of sage extract (sageXtra™) on cognitive function and psychomotor performance in middle-aged men and women, subjects (40-60 years) will receive 333 mg of SageXtra or placebo daily for 8 consecutive weeks.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
64

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

  • BMI 18.5-34.9 (inclusive) with a goal of being < 30 on average
  • Subject agrees to maintain their existing dietary patterns throughout the study period.
  • Subject agrees to refrain from alcohol, caffeine, and strenuous exercise for 24 hours before each test day.
  • Subject is willing and able to comply with the study protocol.
  • Has given voluntary, written, informed consent to participate in the study.

Exclusion Criteria:

  • Individuals with a personal history of a psychiatric disorder.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
COMputerized Mental Performance ASsessment System (COMPASS) Test Battery
Time Frame: 4 weeks and 8 weeks
COMPASS consists of seven components including; 1) Immediate and Delayed Word Recall, 2) Delayed Word Recognition, 3) Delayed Picture Recognition, 4) Corsi Blocks Task, 5) Digit Vigilance, 6) Stroop Test and, 7) Choice Reaction Time evaluated via a computer program.
4 weeks and 8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Physical performance
Time Frame: 4 weeks and 8 weeks
Evaluation of reaction time via a computer program where the subject has to press a key on the keyboard when an area of the computer screen lights up.
