Plasmalogens for Health & Longevity - Quick Reference Sheet

Plasmalogens for Health & Longevity

Created on 08/24/2026 – Quick Reference based on Evidence Review created using AI4L / Grok 4.5 Audit

Plasmalogens are membrane fats that decline with age and run low in dementia and coronary disease. Marine extracts and gram-scale oils raise blood levels. What that does for thinking, mood, walking, or heart-related blood fats is much less settled. Short-term safety is uneventful aside from gastrointestinal adverse events with high-dose oils. Still-unproven restoration strategy; extra healthy years are not proven. (Full Review)

Protocol

Milligram marine-extract approach (Fujino / Japanese Plasmalogen Society; Sunsho ascidian products)
0.5–2 mg/day
Oral purified plasmalogen, usually once daily for 12–24 weeks; morning dosing in Japanese protocols
Gram-scale alkylglycerol-oil approach (Goodenowe / ProdromeNeuro)
900–3,600 mg/day
900 mg/day for a month, then 1,800 mg, then 3,600 mg over 4 months; given non-fasting
Purified shark-liver-oil alkylglycerols (Baker Institute / Alkyrol)
4 g/day
3 weeks; a cardiometabolic research protocol, not a cognition protocol
Time to effect
Triglycerides, free cholesterol, and C-reactive protein
3 weeks
Alkylglycerol-rich oil
Anger, hostility, and fatigue scores
4 weeks
Milligram marine extract
Cognitive function
12–24 weeks
Memory scales in milligram trials

Benefits

Contraindications
  • Known allergy to the source organism (scallop, sea squirt, shark, or chicken, depending on the product)
  • Pregnancy and lactation
  • People seeking an unapproved treatment for dementia, ALS, or autism outside a regulated drug trial
Key Interactions
  • Anticoagulants and antiplatelet drugs (warfarin, apixaban, clopidogrel)
  • Over-the-counter aspirin and NSAIDs (nonsteroidal anti-inflammatory drugs such as ibuprofen, naproxen)
  • Prescription lipid-lowering drugs (statins such as atorvastatin, ezetimibe, fibrates, evolocumab)
  • High-dose omega-3, krill, or other ether-rich oils
  • Other marine-oil supplements

Risk & Side Effects

  • High:
  • Medium: Gastrointestinal upset with high-dose oil precursors
  • Low: Source-organism allergy; Contaminant and identity risk in marine oils
  • Speculative: Unknown long-term safety

Monitoring

Marker Target Why
Blood ethanolamine and choline plasmalogens No established functional range; track change from personal baseline and any age-matched lab reference Confirms the product raises circulating species
Fasting triglycerides Often <100 mg/dL in functional practice (conventional <150 mg/dL) Alkylglycerol oil lowered triglycerides in one small trial
High-sensitivity C-reactive protein Often <1.0 mg/L functionally (conventional <3.0 mg/L) Same trial lowered this inflammation marker
Mini-Mental State Examination or Montreal Cognitive Assessment Change from personal baseline; no plasmalogen-specific target Named scales used in human trials

Cadence: Baseline fasting ether-lipid panel with triglycerides and high-sensitivity C-reactive protein; add a named cognitive scale when memory is the reason. Repeat the plasmalogen panel and lipids at 4 weeks, again at 12 weeks, then every 6–12 months if use continues. Repeat cognitive scales at 12–24 weeks.

Qualitative Assessment

  • Memory for names, recent events, and verbal lists
  • Mental stamina and subjective mental clouding
  • Anger, irritability, and residual fatigue
  • Gait speed, sit-to-stand ease, and fine-motor confidence
  • Sleep onset and night awakening, especially in the first 4 weeks
