PEA Ingredients & Drug Interactions
What is this page for?
First and foremost: checking PEA against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of PEA by Harvest Naturals
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This powder contains one active ingredient: palmitoylethanolamide (PEA), a naturally occurring fatty acid compound. The product has no inactive ingredients listed.
Does it work?
Moderate evidence
PEA is possibly effective for osteoarthritis. For spinal cord injury, the evidence suggests it is possibly ineffective.
For cannabis use disorder, autism spectrum disorder, carpal tunnel syndrome, and migraine headache, there isn't enough reliable evidence to rate whether it works.
How safe is it?
Well-documented data
PEA is generally well tolerated in studies, though long-term safety data are limited. The most common side effect when taken by mouth is nausea, which has been reported rarely and is mild and brief.
When applied topically as a lotion twice daily, a small number of patients with dry skin experienced worsening itching, stinging, scaling, or reddening — but these occurred no more often than with the vehicle (lotion base) alone. There is not enough safety information to use PEA during pregnancy or while breastfeeding — the safety data advises against it.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you have osteoarthritis and want to try a supplement with some evidence behind it, PEA is worth discussing with your doctor or pharmacist. Pregnant or breastfeeding people should avoid it.
If nausea or any skin irritation develops, stop and let your pharmacist know.
