A study on aged female mice found that a two-month regimen of sea squirt-derived plasmalogens improved memory during water maze navigation tests. The treatment also increased neurogenesis and synaptic plasticity in the brains of the mice.
Why it matters
Researchers believe that these fat molecules may maintain cell membrane flexibility, facilitating better neural communication. They also hypothesize that plasmalogens might influence cognitive health through the gut-brain axis.
In a study using aged female mice, subjects receiving sea squirt-derived plasmalogens over a two-month period showed improved memory versus a control group. Researchers also noted reduced microglia activation in the brain, though human impacts remain unknown.
The details
The supplemented mice displayed greater synaptic density and reduced markers of brain inflammation during post-study assessments. Beyond cognitive gains, the treated mice also grew thicker, glossier, and darker coats compared to their untreated counterparts.
Timeline
The administration of plasmalogens to the mice lasted for a two-month period.
The Big Picture
This study situates itself within research on the gut-brain axis, a biological pathway linking gastrointestinal function to neurological outcomes. The findings suggest that specific dietary lipid molecules could serve as a mechanism to modulate this axis to slow age-related decline.
While these findings in mice are promising, the study does not suggest immediate changes to human treatment or dietary habits. Further clinical trials are required before these supplements can be considered safe or effective for human cognition.
The takeaway
This study highlights the potential of marine-derived lipids to influence neural and physical markers of aging. However, it remains a preclinical breakthrough that requires significant testing to validate its utility for human health.
