HelloPharmacist Scorecard of PEA 400 mg 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 product contains one active ingredient: palmitoylethanolamide (PEA) at 400 mg per capsule. PEA is a fatty acid compound that your body produces naturally.
The capsule also holds rice flour and cellulose as inactive ingredients (the filler and capsule material).
Does it work?
Moderate evidence
PEA has been studied most for osteoarthritis, where it's rated possibly effective — meaning some evidence supports it, but we'd like to see stronger data. For spinal cord injury, the evidence suggests it's probably not effective.
For hay fever, autism, bipolar disorder, and ALS, we simply don't have enough reliable evidence to say whether it works or doesn't.
How safe is it?
Well-documented data
PEA is generally well tolerated in the studies we've reviewed, though long-term safety data are limited. The most common side effect from oral use is nausea.
A very small number of trial participants reported drowsiness or a floating sensation, and mild, temporary stomach symptoms have been rarely reported. The safety data advise against using PEA during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.
Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.
Meds to double-check
No known interactions
No interactions are documented in our data for palmitoylethanolamide. That said, because interaction data are limited, confirm with your own doctor or pharmacist before combining this product with any medications you take regularly.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
PEA may be worth considering if you're dealing with osteoarthritis and interested in exploring natural options. The evidence for other conditions is either lacking or points toward it not working.
Before you start, check with your own doctor or pharmacist — especially if you're on any regular medications — because we don't have interaction data on file. If nausea or drowsiness shows up, scale back or stop and talk it over with your pharmacist.
