PEA Supplement Side Effects: What Trials and Animal Tests Show
PEA supplement side effects look mild in the studies we have: an 11-trial review with 774 patients found no major side effects blamed on PEA. Long-term safety comes from animal tests, not people. SciatiEase's other ingredients, such as B6 and herbs, carry their own cautions, so read the whole panel.

What is known01
What are the side effects of PEA supplements?
No major side effects were attributed to PEA in the trials we reviewed.
The meta-analysis covered 11 double-blind trials and 774 patients (Lang-Illievich et al., Nutrients 2023). A review of sciatica and carpal tunnel studies likewise lists no troublesome side effects or drug interactions (Keppel Hesselink, J Pain Res 2015).
That is reassuring but not a clean bill. Trials last weeks, and small problems may go unreported.
Long term02
Is long-term PEA use safe?
Unproven in people. The longest safety work is in rats.
Micronized PEA showed no gene damage in lab tests. Rats given up to 1,000 mg/kg a day for 90 days showed no ill effect at the top dose (Nestmann, Food Sci Nutr 2017).
| Evidence | Type | Limit |
|---|---|---|
| 11 trials, 774 patients (Lang-Illievich et al., Nutrients 2023) | Human | Short trials |
| Sciatica review (Keppel Hesselink, J Pain Res 2015) | Human | 3-week main trial |
| 90-day dosing (Nestmann, Food Sci Nutr 2017) | Rat | Not human data |
The formula03
Do PEA side effects change in a blend?
The other lines matter more than the PEA.
- Vitamin B6 at 20 mg is above Australia's 10 mg warning line (TGA, Vitamin B6 and neuropathy).
- Feverfew may slow clotting (NCCIH, Feverfew).
- Alpha lipoic acid may lower blood sugar (Linus Pauling Institute, Lipoic Acid).
Keep taking prescribed medicine, and tell your pharmacist about SciatiEase. Gelatin capsules are not vegetarian.

See packsWhen to stop04
When should you stop PEA and call someone?
Stop the capsules and ask a clinician if a new rash, stomach upset or odd symptom starts.
Leg weakness, numbness in the groin or loss of bladder control need urgent care (MedlinePlus, Sciatica). Read PEA dosage and PEA for sciatica too.
FAQ05
PEA safety questions
Does PEA cause stomach upset?
Our sources name no stomach side effect for PEA (Lang-Illievich et al., Nutrients 2023). SciatiEase has other lines that may, such as carnitine (NIH ODS, Carnitine).
Can PEA interact with medicines?
The review we use lists no drug interactions (Keppel Hesselink, J Pain Res 2015). That is limited data, so ask your pharmacist.
Is PEA safe for pregnancy or nursing?
We found no safety data for those groups. Ask your clinician; feverfew in the blend is not for pregnancy (NCCIH, Feverfew).
Are PEA side effects dose related?
Rats showed no effect up to 1,000 mg/kg (Nestmann, Food Sci Nutr 2017). Human dose tracking is thin.
Has PEA been linked to liver problems?
Nothing in our sources says so for PEA. Chinese skullcap in the blend has liver reports (MSKCC, Scutellaria baicalensis).
