Could ‘sea squirts’ hold a clue to healthier ageing?

Sea squirts, common in Japan and South Korea but rarely eaten in Malaysia, may hold secrets to healthier ageing. These marine animals possess high levels of plasmalogens, compounds researchers are investigating for their potential benefits in brain health. Despite their decline with age, plasmalogens have been linked to improved memory, healthier brain connections, and reduced inflammation in mice.

In a study involving aged female mice receiving plasmalogen supplements, those treated showed better memory and learning abilities compared to untreated older mice. Their brains displayed healthier synapses and lower inflammation, potentially aiding nerve cell communication and formation. The researchers also noted increased synaptic plasticity and neurogenesis, key processes in maintaining brain function.

Signs of improved hair quality were also observed in the supplemented mice, but no definitive conclusions can be drawn about sea squirts' potential as an anti-ageing solution or cure for grey hair. While the findings provide intriguing insights, further research through clinical trials is needed to validate the potential benefits of plasmalogen supplements for human cognition and ageing.
