Study
Spearmint Extract May Improve Memory and Sleep in Older Adults
Taking 900mg of spearmint extract daily showed significant improvement in working memory and sleep for adults with age-related memory issues.
Summary
In plain language
A recent study found that a daily dose of 900mg spearmint extract can improve memory and sleep quality in older adults experiencing age-related memory concerns. Participants taking the higher dose of spearmint extract showed a 15% improvement in working memory and reported better sleep compared to those taking a placebo. This is promising news for seniors looking to maintain cognitive health and improve their quality of life without medication. The study offers hope that a simple herbal supplement could support memory and sleep, which are common challenges as we age.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study was conducted with 90 participants who had age-related memory impairment. They were divided into three groups, each receiving either 900mg, 600mg, or no spearmint extract (placebo) daily for 90 days. Researchers assessed cognitive function, sleep quality, and mood.
Participants taking 900mg of spearmint extract experienced a 15% boost in working memory and improved sleep quality.
The study was carefully designed to eliminate bias, using a double-blind, placebo-controlled method.
While results are encouraging, it's important to note that the study was funded by the manufacturer of the spearmint extract.
Seniors interested in trying spearmint extract should consult with their healthcare providers to ensure it's safe and appropriate for their health needs.

Research Quality Score
Scored September 29, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study's high score is due to its rigorous randomized controlled trial design. However, the lack of allocation concealment details, absence of multiple comparison adjustments, and funding from the product's manufacturer reduce its bias control and statistical integrity scores. Transparency is limited by the lack of pre-registration and data sharing. The study is relevant to the target population, but journal quality is unassessable due to missing information.

Conditions This Research Covers
These condition pages help connect the paper back to the real-world health concerns it addresses.
Dementia
Dementia is a broad term used to describe a decline in cognitive function that interferes with daily life. It predominantly affects older adults, with symptoms like memory loss and changes in behavior. Dementia is not a normal part of aging, and early diagnosis is crucial for management.
Alzheimer's Disease
Alzheimer's disease is a progressive neurological disorder that affects memory, thinking, and behavior. It primarily impacts older adults, with symptoms gradually worsening over time. As the most common cause of dementia, Alzheimer's can lead to a significant decline in daily functioning and independence.
Sleep Deprivation
Sleep deprivation, a condition characterized by insufficient sleep, is a common problem that can significantly impact health and well-being. It is particularly concerning for older adults, as their sleep needs may change with age. Chronic sleep deprivation can lead to a variety of health problems, including cognitive impairment, mood disorders, and increased risk of accidents.
Hearing Loss (Age-Related)
Age-related hearing loss, also known as presbycusis, is a common condition that affects many older adults. It occurs gradually over time, often leading to difficulty hearing high-frequency sounds. This can impact communication, social interactions, and overall quality of life.
