Phosphatidylcholine (PC) is a phospholipid and a major component of cell membranes, and it plays a role in the synthesis of acetylcholine, a neurotransmitter important for memory and cognitive function. The rationale behind using PC for Alzheimer's Disease (AD) is that increasing choline availability might boost acetylcholine levels, which are typically reduced in AD. Some early studies and animal models suggested that choline supplementation could enhance cognitive performance. However, large-scale, well-controlled clinical trials in humans have not shown consistent or significant benefits of phosphatidylcholine supplementation for Alzheimer's patients. Most studies have not demonstrated an improvement in cognitive decline or daily functioning compared to placebo. Reviews and meta-analyses of the data have concluded that there is insufficient evidence to support the use of PC as an effective treatment for AD.

Despite some early scientific interest, current medical guidelines do not recommend phosphatidylcholine for Alzheimer's Disease due to the lack of compelling clinical evidence. It is not a traditional remedy for AD, nor is it a standard part of evidence-based treatment protocols. In summary, while the scientific rationale exists, the actual clinical evidence supporting its use is weak (evidence rating: 1 out of 5).
