Lysoveta for memory in healthy adults with self-perceived memory problems

A Randomized, Triple-blind, Placebo Controlled, Parallel Clinical Trial to Examine Lysoveta on Cognitive Function in Healthy Adults With Self-perceived Memory Problems

This trial will test whether taking Lysoveta (a hydrolyzed krill oil supplement) improves memory in healthy adults aged 50–75 who report mild memory problems.

What this trial studies

This is a randomized, placebo-controlled, triple-blind, parallel-group trial comparing Lysoveta to placebo in healthy volunteers aged 50–75 who report subjective memory problems. Participants are randomly assigned to receive Lysoveta or matching placebo and complete repeated computerized cognitive testing and mood questionnaires over the study period. Cognitive outcomes are measured with the Computerized Mental Performance Assessment System (COMPASS), focusing on episodic, working, and spatial memory. The study aims to detect differences in change on those memory domains between the Lysoveta and placebo groups.

Who should consider this trial

Good fit: Healthy adults aged 50–75 who report subjective memory problems and meet the study's pregnancy and contraception requirements are the intended participants.

Not a fit: People with diagnosed dementia, major neurological or psychiatric conditions, or those outside the 50–75 age range are unlikely to receive benefit from this trial.

Why it matters

Potential benefit: If effective, Lysoveta could modestly improve episodic, working, and spatial memory in older adults who notice memory decline.

How similar studies have performed: Previous trials of omega‑3 and krill oil supplements have shown mixed results for cognition, so the approach has some supporting evidence but is not yet proven.
