Plasmalogens are a special type of phospholipid. They are found in high concentrations in the brain, heart, lungs, kidneys, and eyes. Plasmalogens are not some trace nutrient, they actually build a big part of the brain, as much as 20% of the dry weight.
Plasmalogens act as a reservoir for important fatty acids including oleic acid, arachidonic acid, and docosahexaenoic acid (DHA)[i]. Plasmalogens are anti-inflammatory, are powerful antioxidants, are a critical part of cell membranes, maintain optimal brain function, and are a major structural part of lipoproteins, myelin, and synaptic membranes[ii].
Plasmalogen levels in the brain increase up to 30 to 40 years of age and then significantly decrease by around 70 years of age[iii]. There are no adequate food sources. The body makes plasmalogens in the peroxisomes of cells; the majority are made in the liver. The body’s ability to make plasmalogens becomes impaired as peroxisome function is compromised with age and plasmalogens are degraded from inflammation and oxidative stress.

why are low levels of plasmalogens bad?
Data from the Rush University Memory and Aging Project showed that a 95-year-old with high plasmalogen levels had the same chance of dying in five years as a 65-year-old with low plasmalogen levels. A 95-year-old with high levels had an almost 70 percent chance of living to their 100th birthday whereas a person the same age with low plasmalogen levels had a less than 20 percent chance of living to their 100th birthday. These results were shocking.
Decades of data show that low plasmalogen levels have severe health effects and that plasmalogen supplementation has positive health effects.
Plasmalogens and Death
There is no question that plasmalogens are important for health. But what about having low levels of plasmalogens – just how bad can it be? I have made a lot of graphs in my career and only one graph has actually scared me: the relationship between blood plasmalogen levels and death.
Probability of dying in 5.3 years
Data from the Rush University Memory and Aging Project. Final dataset: 1262 participants, participants still living since last clinical visit = 896, participants deceased since last visit = 862. Average age at enrollment = 81. Low plasmalogens = 5th percentile +/- 95% CI. High plasmalogens = 95th percentile +/- 95% CI.
why do we get low levels of plasmalogens?
The body makes a lot of plasmalogens and consumes a lot. Plasmalogen deficiency occurs when the body can no longer make as much as it consumes. This can happen due to increased oxidative stress which degrades plasmalogens[i] or decreased biosynthesis caused by aging and chronic exposure to xenobiotics[ii].

plasmalogens and the cause of diseases
What happens when there are not enough plasmalogens in the body? Plasmalogens have both structural and functional roles in the brain. Plasmalogen deficiency leads to cell membrane changes in structure, geometry, and function as the body is forced to substitute other molecules such as phosphatidylethanolamines in place of plasmalogens. This leads to cellular signaling abnormalities and neurotransmission deficits as well as lowered antioxidant defenses[i].
Inflammation can lead to a vicious cycle where oxidative stress degrades plasmalogens which further reduces the anti-inflammatory and antioxidative capacity of the tissues ultimately leading to clinical symptoms of disease[ii].

plasmalogens to prevent disease
Plasmalogens prevent neurodegeneration in animal models; the majority of the publications are for Parkinson’s disease. In a mouse model of Parkinson’s disease, an oral dose of plasmalogen at 50mg/kg was fully neuroprotective[i]. Several publications demonstrate the neuroprotective and anti-inflammatory properties in mouse and monkey models of Parkinson’s disease[ii],[iii],[iv],[v].

Scientifically designed plasmalogen supplement
After years of extensive research I designed plasmalogen supplements as a plasmalogen precursor that survives the gut and is then converted to the target plasmalogen molecule independent of peroxisomal function.
I first designed and invented a series of plasmalogen drugs because at the time there was a patent protecting the use of natural plasmalogens for dementia which just expired last year. I have since designed and developed natural plasmalogen supplements, the first being ProdromeNeuro developed by my company Prodrome Sciences, that has the same activity as my previously invented PPI-1011 plasmalogen drug.
While we continue to advance research on plasmalogens to answer important questions about the use in disease management, one thing is clear today: plasmalogens are an essential brain nutrient you do not want to be low on. Our scientifically designed, natural plasmalogen supplement ensures there is an adequate amount of plasmalogens in the blood supply for health.
