PEA: the promising new natural anti-inflammatory for endometriosis

When it comes to managing the symptoms of endometriosis, natural treatment options are gaining in popularity among women seeking alternatives or complements to traditional medical treatments. Among these options, AEP stands out as a promising dietary supplement with anti-inflammatory and analgesic effects that could play a key role inrelieving this painful condition.

What is a PEA?

PEA (palmitoylethanolamide) is a fatty acid amide belonging to the class of lipid modulating factors, found naturally in our bodies. It is produced locally by cells in response to injury or inflammation to combat pain and reduce inflammation. In addition to its presence in the human body, PEA is also found in many of the foods we eat, such as eggs 🍳, peanuts 🥜, soy 🌱, and meat 🥩.

1. Egg yolk: Egg yolk is a rich source of PEA. It also contains other essential nutrients, making it a beneficial addition to the diet.

2. Soy lecithin: Soy lecithin, often used as a dietary supplement and emulsifier in processed foods, is another source of PEA.

3. Peanuts: Peanuts are a natural source of PEA. They also provide protein, healthy fats and various micronutrients.

4. Whole milk: Whole milk also contains PEA, although in relatively small quantities compared to other sources.

5. Soya: Soya and soy-derived products such as tofu and tempeh contain PEA.

Where can I find the PEA?

PEA can be obtained in two ways: through the consumption of foods that naturally contain it, or through supplements. Although our bodies produce it in small quantities, the use of PEA supplements may be necessary to reach the concentrations needed to observe significant therapeutic effects, particularly for those suffering from chronic conditions such as endometriosis, neuropathic pain, or other types of chronic inflammation.

How does the PEA work?

PEA functions primarily as an anti-inflammatory and analgesic agent.

Here's how it works:

1. Modulation of inflammation: PEA acts by inhibiting the production of pro-inflammatory compounds in cells. It acts directly on certain immune cells, preventing them from releasing substances that contribute to inflammation and pain.

2. Interaction with cellular receptors: PEA interacts with specific receptors in the body, known as PPAR-α (peroxisome proliferator-activated receptor alpha) receptors. This interaction helps reduce inflammation and relieve pain by modulating intracellular signaling pathways.

3. Analgesic effect: In addition to its anti-inflammatory properties, PEA has analgesic effects which are achieved by modulating neuronal responses to pain. It helps reduce nerve sensitivity to pain, which is particularly useful for chronic pain conditions.

What are the scientific studies on PEA?

PEA (palmitoylethanolamide) has been the subject of several scientific studies, notably to assess its efficacy in the treatment of pain and inflammation associated with various women's health conditions, including endometriosis. Here are a few significant studies that have examined the use of PEA in this context:

AEP and endometriosis study

• Title: "Palmitoylethanolamide, a Naturally Occurring Disease-Modifying Agent in Neuropathic Pain".
• Abstract: This study explores how PEA modifies the mechanisms of neuropathic pain, which may be a component of the pain experienced by women with endometriosis. It showed that PEA reduces pain by acting on alpha receptors, which play a role in modulating pain and inflammation.

Study on AEP and chronic pelvic pain syndrome

• Title: "Effects of Palmitoylethanolamide on the Symptom Quality of Life in Women with Chronic Pain"
• Abstract: This study examined the efficacy of PEA in the treatment of chronic pelvic pain syndrome, often present in women with inflammatory conditions such as endometriosis. Results indicated a significant improvement in participants' quality of life after treatment with PEA.

Study on PEA and menstrual pain

• Title: "A Placebo-Controlled Study of Palmitoylethanolamide for the Treatment of Painful Menstruation".
• Abstract: This research investigated the impact of AEP on menstrual pain, which is frequently exacerbated in women with endometriosis. AEP showed a significant reduction in pain compared with placebo.

Study on PEA and systemic inflammation

• Title: "Palmitoylethanolamide: A Comprehensive Review of Its Anti-inflammatory Activity".
• Abstract: This review article provides a detailed analysis of the anti-inflammatory action of PEA, suggesting its potential as a treatment for various inflammatory conditions, including those affecting women's health.

What are the other women's health benefits? 

Although often cited for its beneficial effects in the treatment of endometriosis and chronic pain, it also offers several other benefits for women's health. These include relief from symptoms associated with premenstrual syndrome (PMS), reduced inflammation in other inflammatory conditions, and even potential implications for mental health. Here's a more detailed exploration of these benefits : 

Reducing Premenstrual Syndrome (PMS) Symptoms

It can help alleviate the symptoms of PMS, which affects many women every month. Symptoms such as cramps, swelling, mood swings and irritability can be exacerbated by inflammatory processes.

Improving Pelvic Health

PEA also plays a role in the management of pelvic pain, often present in conditions such as endometriosis, uterine fibroids and interstitial cystitis. By modulating pain and inflammation via cellular and molecular mechanisms, PEA can help improve the quality of life of women suffering from these conditions. Research indicates that PEA can reduce the frequency and intensity of pelvic pain, offering lasting relief without the side effects of traditional analgesics.

Potential in the Treatment of Depression and Anxiety

Preliminary studies suggest that PEA may have beneficial effects on mental health, particularly with regard to depression and anxiety, which are more common in women. PEA influences neuroinflammatory pathways that may be involved in the pathogenesis of depression and anxiety. By reducing neurological inflammation, PEA can help stabilize mood and improve the symptoms of these mental disorders, offering a complementary approach to conventional psychiatric treatments.

Effects on Neurological Health

PEA has shown neuroprotective properties in various studies, suggesting that it may play a role in protecting against neurodegenerative diseases. Although these diseases are not specific to women, improving neurological health is crucial to long-term quality of life, particularly as populations age. By protecting neurons from damage and inflammation, PEA can help maintain cognitive function and prevent neurological damage. 

To go further, we need to understand the relationship between PPAR-α & PEA

PPAR-α (peroxisome proliferator-activated receptor alpha) receptors are a class of nuclear receptors that play a crucial role in the regulation of lipid and carbohydrate metabolism, as well as in the modulation of inflammation. They are widely studied for their involvement in various bodily functions and their therapeutic potential in numerous diseases.

It interacts with PPAR-α, which partly explains its anti-inflammatory and analgesic effects. By activating these receptors, PEA helps reduce the production of inflammatory substances. 

Function of PPAR-α receptors

PPAR-α are essential for the regulation of energy metabolism in the body. They are mainly expressed in tissues that are active in fatty acid metabolism, such as the liver, skeletal muscle, heart, and kidney. Their key functions:

1. Lipid metabolism regulation: PPAR-α activates genes involved in fatty acid degradation. By stimulating fatty acid oxidation, they help reduce blood triglyceride levels and increase HDL ("good") cholesterol levels.

2. Regulation of carbohydrate metabolism: although their main role is in lipids, PPAR-α also influences carbohydrate metabolism by helping to regulate glucose production by the liver.

3. Modulation of inflammation: PPAR-α plays an anti-inflammatory role by inhibiting the production of inflammatory molecules by immune cells. This makes them particularly interesting for the treatment of chronic inflammatory diseases.

Therapeutic importance of PPAR-α

For all these reasons, and because of their essential role in lipid metabolism and the regulation of inflammation, PPAR-α are very often targeted by several drugs, notably those used to treat lipid disorders, type 2 diabetes, and certain inflammatory diseases. 

How to top up your PEA?

The dosage of PEA (palmitoylethanolamide) may vary according to the conditions to be treated, the severity of symptoms, and the formulations available. PEA is used for a wide range of inflammatory and painful conditions, so the optimal dose may differ from one woman to another.

Here are some general guidelines on the known dosage of PEA based on current usage and clinical studies:

Standard PEA dosage

1. Usual Dose for Pain and Inflammation Management :

   • The usual adult dose of PEA ranges from 600 mg to 1200 mg per day.
   • This dose is often divided into two doses, one in the morning and one in the evening.

2. For Acute or Severe Pain:

   • In cases of acute or severe pain, such as those associated with neuropathic conditions or endometriosis, the dose may be temporarily increased.
   • Some practitioners may recommend up to 1600 mg a day, divided into two or three doses.

3. Duration of treatment :

   • AEP may require prolonged use to observe maximum efficacy, often recommended for at least 2 to 3 months before full effectiveness is assessed.

Overdose Considerations

• Absence of known overdose: To date, there are no known reports of PEA overdose. This is probably due to its natural mechanisms of action and high safety profile.
• No accumulation: PEA does not tend to accumulate in the body, which reduces the risk of long-term toxicity.

Precautions

• Medical Monitoring: Although the risk of overdose is low, it is always prudent to start any new supplement, including AEP, under the supervision of a healthcare professional. This is particularly important for people taking other medications or with pre-existing medical conditions.
• Observing side effects: Any change in health or appearance of side effects while taking PEA should be discussed with a physician.
