Phosphatidylserine is a phospholipid found in high concentrations in the brain and is widely studied for its effects on cognitive function, which is an aspect of the Senses body system, particularly regarding memory and attention. Scientific studies have shown that phosphatidylserine supplementation can have small benefits in improving cognitive performance, especially in elderly individuals experiencing memory decline or cognitive impairment. Some randomized controlled trials have reported modest improvements in memory, attention, and other cognitive parameters with supplementation, though results are mixed and often limited by small sample sizes and short durations. There is also some evidence suggesting that phosphatidylserine may support neurotransmitter function and synaptic activity, which could theoretically influence sensory processing. However, the majority of the research focuses on cognitive aspects rather than direct improvements in senses such as vision, hearing, or smell. Regulatory bodies such as the FDA allow qualified health claims related to cognitive decline in the elderly, but stress that the evidence is limited and not conclusive. In summary, while there is some scientific basis for phosphatidylserine’s support of brain functions connected to the senses, the evidence for direct effects on sensory function is weak, and most benefits are modest and primarily related to cognition.
