PEA: The promising new natural anti-inflammatory for endometriosis

When it comes to managing the symptoms of endometriosis, natural treatment options are gaining popularity among women looking for alternatives or complements to traditional medical treatments. Among these options, PEA 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 PEA?

PEA (palmitoylethanolamide) is a fatty acid amide belonging to the class of lipid modulating factors, which is found naturally in our body. It is produced locally by cells in response to injury or inflammation to fight pain and reduce inflammation. In addition to its presence in the human body, PEA is also found in many of the foods we consume, such as eggs 🍳, peanuts 🥜, soybeans 🌱, 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 the amounts are relatively small compared to other sources.

5. Soybeans : Soybeans and soybean 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 amounts, the use of PEA supplements may be necessary to achieve the concentrations necessary to observe significant therapeutic effects, especially for those who suffer from chronic conditions such as endometriosis, neuropathic pain, or other types of chronic inflammation.

How does the PEA work?

The functioning of PEA is mainly related to its action as an anti-inflammatory and analgesic agent.

Here's how it works:

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

2. Interaction with cell receptors: PEA interacts with specific receptors in the body, known as PPAR-α receptors (receptor activated by alpha peroxisome proliferators). 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 that are achieved by modulating neuronal responses to pain. It helps reduce the nerves' sensitivity to pain, which is especially helpful for chronic pain conditions.

What are the scientific studies on PEA?

PEA (palmitoylethanolamide) has been the subject of several scientific studies, including evaluating its effectiveness in treating pain and inflammation associated with various women's health conditions, including endometriosis. Here are some significant studies that have looked at the use of PEA in this context:

PEA and Endometriosis Study

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

PEA and Chronic Pelvic Pain Syndrome Study

• 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, which is often present in women with inflammatory conditions such as endometriosis. The results indicated a significant improvement in participants' quality of life after treatment with PEA.

PEA and Menstrual Pain Study

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

PEA and Systemic Inflammation Study

• 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 health benefits for women? 

Although it is 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 effects include relieving symptoms related to premenstrual syndrome (PMS), reducing inflammation in other inflammatory conditions, and even potential mental health implications. Here's a more detailed exploration of these benefits: 

Reduction of 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.

Improved Pelvic Health

PEA also plays a role in the management of pelvic pain, which is often present in conditions such as endometriosis, uterine fibroids, and interstitial cystitis. By modulating pain and inflammation through 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, providing long-lasting relief without the side effects of traditional pain relievers.

Potential in the Treatment of Depression and Anxiety

Preliminary studies suggest that PEA may have beneficial effects on mental health, particularly when it comes 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 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. While these diseases are not specific to women, improving neurological health is crucial for long-term quality of life, especially as populations age. By protecting neurons from damage and inflammation, PEA can help maintain cognitive function and prevent neurological damage. 

To go further, it is necessary to understand the PPAR-α & PEA relationships

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

It interacts with PPAR-α, which partly explains its anti-inflammatory and analgesic effects. By activating these receptors, PEA helps to 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 kidneys. Their key functions:

1. Regulation of Lipid Metabolism: PPAR-α activate genes involved in the breakdown of fatty acids. By stimulating the oxidation of fatty acids, they help reduce triglyceride levels in the blood and increase levels of HDL (the "good" cholesterol).

2. Regulation of Carbohydrate Metabolism: Although their primary role is in lipids, PPAR-α also influence carbohydrate metabolism by helping to regulate the liver's production of glucose.

3. Modulation of Inflammation: PPAR-α play 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 of these reasons and their essential role in lipid metabolism and the regulation of inflammation, PPAR-α are very often targeted by several drugs, including those used to treat lipid disorders, type 2 diabetes, and certain inflammatory diseases. 

How to take your PEA supplement?

The dosage of PEA (palmitoylethanolamide) may vary depending on 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 woman to woman.

Here are some general guidelines on known PEA dosing based on common usage and clinical studies:

Dosage Standard du PEA

1. Standard Dose for Pain and Inflammation Management:

   • The usual dose of PEA for adults ranges between 600 mg and 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 increased temporarily.
   • Some practitioners may recommend up to 1600 mg per day, divided into two or three doses.

3. Duration of Processing:

   • PEA may require prolonged use to observe maximum efficacy, often recommended for at least 2 to 3 months before its full efficacy is evaluated.

Overdose Considerations

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

Precautions

• Medical follow-up: Although the risk of overdose is low, it is always prudent to start any new supplement, including PEA, under the supervision of a healthcare professional. This is especially important for people taking other medications or with pre-existing medical conditions.
• Observation of Side Effects: Any changes in health or occurrence of side effects while taking PEA should be discussed with a doctor.
