PEA is available in Europe as PeaPure, a supplement with the highest purity of PEA in each serving (capsule; tablet) (around 30% higher compared to Normast). We recommend this supplement, as it does not contain any pharmaceutical excipients, it contains PEA in a pure form.
PEA and neuro-restoration
A new scientific paper from the university of Florence, Italy, highlights the special characteristics of the natural painkiller palmitoylethanolamide (PEA). The researchers found clear indications that PEA not only inhibit pain in a natural way, but hand in hand with the painkilling properties this nutraceutical protects nerves against damage and stimulates neuro-restoration.
The authors point out that their experiments support PEA as an natural analgesic ANd a disease-modifying agent for peripheral neuropathy. This combination of special properties and a trippel action is new for a painkiller. PEA is already available in Europe as PeaPure, a nutraceutical.
PEA as a analgesic, anti-inflammatory compound and as a neuro-restorative agent
The natural compound and painkiller palmitoylethanolamide (PEA) has been explored recently by pharmacologists from the university of Florence. In their paper, bearing the tite:
Palmitoylethanolamide Is a Disease-Modifying Agent in Peripheral Neuropathy: Pain Relief and Neuroprotection Share a PPAR-Alpha-Mediated Mechanism
The authors point out that neuropathic syndromes are extremely difficult to treat, and available drugs rarely joint an antihyperalgesic with a neurorestorative effect.
N-Palmitoylethanolamine (PEA) however, exerts both an antinociceptive effect and inhibits peripheral inflammation. The authors wanted to analyse this dual mechanism of PEA in more detail. In a sciatic nerve trauma model daily treatment with PEA prevented pain threshold alterations. Repeated treatments with PEA also reduced the presence of damage in the nerves, such as edema and macrophage infiltrates. Furthermore, a significant higher myelin sheath, axonal diameter, and a number of nerve fibers were detected.
In mice without the PPAR- α target, the PEA treatment was not analgesic, neither resulted in rescue of the peripheral nerve from inflammation and other pathology.
The authors concluded that PEA has both an analgesic effect, as well can lead to neuro-restoration. Both small nerve fibres, as well as large nerve fibres can be protected by PEA:
These results strongly suggest that PEA, via a PPAR- α -mediated mechanism, can directly intervene in the nervous tissue alterations responsible for pain, starting to prevent macrophage infiltration.
These findings of a combination of natural analgesia, inhibition of inflammation and nerve-protection with neuro-restorative properties is a breakthrough in the neurobiology of pain.

Recently Kapoor summerized some of the protective effects of PEA in:
Emerging Neuroprotective Effects of N-Palmitoylethanolamide Besides Its Significant Antinociceptive Effects
( Kapoor S. in: Pain Med. 2013 Apr 12. doi: 10.1111/pme.12118.)
“N-palmitoylethanolamide (PEA) exerts a number of other neuro- protective effects besides its significant antinociceptive effects.” The effects of PEA as summerized by him:
1. PEA attenuates chemotherapy-induced neuropathies by attenuating endoneueral edema in myelinated nerve fibers
2. PEA improves distal motor latency in individuals with carpal tunnel syndrome
3. PEA ehas beneficial effects in patients with multiple sclerosis by ameliorating neuropathic pain
5. PEA decreases immobility in an animal model of depression, and thereby exerts a significant anti- depressant effect
6. PEA has neuroprotective effects which are a result of direct attenuation of astrocyte infiltration
7. PEA might be useful in sleep disorders such as narcolepsy as it enhances waking by modulating dopamine and anandamide levels
8. PEA might have a plausible role in Alzheimer’s disease and other forms of dementia.
The examples clearly illustrate the potent neuroprotective effects of PEA
