Soy Lysolecithin LPC70 Eases Blood Pressure and Memory Effects of High-Salt Diet in Mice

Study Background

Researchers from Fujita Health University, in collaboration with ingredient developer Tsuji Oil Mills, tested soy-derived lysolecithin with 70% phospholipid content, called LPC70, in male mice fed a high-salt diet.

The study, reported in Neurochemistry International, aimed to clarify the biological mechanisms behind earlier observations that LPC70 reduces hypertension and cognitive impairment linked to high sodium intake.

Main Findings

High-salt-fed mice showed elevated blood pressure, reduced social interaction, and impaired object recognition memory, and LPC70 supplementation lowered blood pressure and improved both behavioral measures.

Mechanistically, the authors linked the effects to organ-specific protective prostaglandin signaling, including normalization of the prostaglandin E2 receptor EP3 in the kidney and restoration of the neuroprotective prostaglandin D2 receptor DP1 in the prefrontal cortex.

LPC70 also boosted arachidonic acid-derived protective prostaglandin production despite lower circulating arachidonic acid levels on the high-salt diet.

Alıcı Paketi

The authors suggest LPC70 could be explored as a functional food ingredient for populations with high dietary salt intake, with clinical research as the next step.

For ingredient buyers, the study highlights lysolecithin fractions as a potential positioning option in sodium-management and cognitive-wellness food formats, while the evidence remains at the animal-model stage.
