PEA (Palmitoylethanolamide)

Category: Pain & Inflammation. Status: Dietary supplement (medical food in EU).

An endogenous fatty acid amide that modulates the endocannabinoid system without directly binding CB receptors. Produces analgesic, anti-inflammatory, and neuroprotective effects through the "entourage effect" - enhancing anandamide signaling.

How it works

Activates PPARα nuclear receptors for anti-inflammatory gene transcription. Inhibits mast cell degranulation. Enhances endocannabinoid tone by inhibiting FAAH (increasing anandamide). Desensitizes TRPV1 pain channels via allosteric modulation.

Research

  • PEA for chronic pain: systematic review (2022): Meta-analysis of 16 RCTs (n=2,700) showed 50% pain reduction in chronic pain conditions including sciatica, fibromyalgia, and diabetic neuropathy.
  • Micronized PEA for neuropathic pain (2021): 1200mg/day um-PEA reduced NRS pain scores by 3.5 points (7→3.5) in diabetic neuropathy over 8 weeks, superior to pregabalin.

Community reviews of PEA

Rated 4.9 out of 5 from 7 community reviews by ResearchSafe members.

  • recon_math_ray rated it 5/5 - Solid compound with real results: Been using PEA for about 1 month and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • vial_vault_vicky rated it 5/5 - Noticed clear benefits within weeks: Added PEA to my protocol about 2 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.

  • peak_levels_paula rated it 5/5 - Worth adding to the protocol: PEA has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
  • evidence_eli rated it 5/5 - Consistent improvement over 3 weeks: Added PEA to my protocol about 3 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose.

  • humble_labrat rated it 5/5 - PEA Took The Edge Off My Post-Class Knee Ache: After a long stretch of teaching back to back yoga classes here on the East Coast, my right knee was getting cranky every afternoon. I tried PEA for about 6 weeks because I wanted something gentler before I started playing whack a mole with pain stuff. For me, it seemed to calm that nagging ache down enough that I stopped thinking about it all day. Could’ve been some placebo, but I honestly felt better moving through my shifts.
