What palmitoylethanolamide is and how the forms differ
What palmitoylethanolamide actually is
Palmitoylethanolamide, usually shortened to PEA, is a fatty acid amide. Your body makes small amounts of it from palmitic acid. It also occurs naturally in food: egg yolk, peanuts and soy lecithin contain traces. In supplements you will find it as a fine white powder, packed into capsules, tablets, sachets or sold loose.
PEA belongs to the same family as the other fats and oils we stock. In the UK it is sold as a food supplement, not a medicine. The European food safety authority (EFSA) has not approved a health claim for palmitoylethanolamide. That means no benefit wording is allowed on the label, and we do not add one here either. What we can be precise about is form, dose and purity, because that is where products genuinely differ.
Particle size is the main difference between products
PEA barely dissolves in water. That makes the size of the powder particles the most useful detail on the label. Three descriptions are common:
- Standard PEA: not ground down, largest particles, usually the cheapest.
- Micronised PEA: milled into much smaller particles, so more surface meets the gut wall.
- Ultra-micronised PEA: milled finer still, and the form most studies have used.
A few brands use a liposomal version instead. Liposomal means the PEA is wrapped in a tiny fat layer, so the body takes it up more easily. Whatever the wording, check the milligrams per capsule, not only per serving of two or three capsules. Two products with the same number on the front can differ by half once you count capsules.
How we select palmitoylethanolamide
We look at three things before a PEA product joins our range: the form, the dose per capsule, and whether any added ingredients earn their place. We prefer micronised and ultra-micronised powder, because particle size is what the research was built on. We want the milligrams stated per capsule, so you can count your own intake instead of guessing. Combinations only when each ingredient has a reason to be there. We buy directly from the brands, our compliance team checks every product before it goes live, and independent labs spot-check batches. You can read how we select brands and products.
Who buys it, and what to expect
Most people who buy PEA are adults who train regularly, spend long days on their feet, or want something to add to an existing daily routine. It is often chosen alongside supplements with curcumin, since both are taken as a daily habit rather than now and then.
Be realistic about the timeline. PEA is not a quick fix: give it two to three weeks of consistent daily use before you decide whether it belongs in your routine. Take it with a meal that contains some fat, and split the day's amount over two moments if your product allows it. Many people find the powder easier to divide than capsules. If you prefer to browse by goal rather than by ingredient, our MOVE + RECOVER pillar collects the products people use for training and daily activity.
One honest note: PEA never replaces anything your doctor has prescribed. If you are pregnant, breastfeeding, under 18 or taking medication, speak to your GP or pharmacist before you start.
Frequently asked questions
Palmitoylethanolamide is a fatty acid amide, a fat-like substance built from palmitic acid and ethanolamine. Your body produces it in small amounts itself, and it appears in traces in foods such as egg yolk, peanuts and soy lecithin. As a supplement it is a fine white powder, sold in capsules, tablets, sachets or loose. In the UK it is regulated as a food supplement, so labels describe what is in the product rather than what it does.
Almost all supplement PEA is made in a lab, not extracted from food. Food sources contain far too little to be practical: you would need an unrealistic amount of egg yolk or peanuts to match one capsule. Manufacturers combine palmitic acid, usually of vegetable origin, with ethanolamine to produce a pure powder. That is also why quality questions focus on purity, particle size and the milligrams per capsule rather than on the plant or animal it came from.
The choice comes down to how finely the powder is milled, since PEA hardly dissolves in water.
| Form | What it means | Suits |
|---|---|---|
| Standard | Not milled down | Budget starters |
| Micronised | Smaller particles | Most daily users |
| Ultra-micronised | Finest particles | Following study forms |
| Liposomal | Wrapped in fat layer | Lower doses, liquids |
We mostly stock micronised and ultra-micronised powder, because that is the form the research used.
Take it daily, with a meal that contains some fat, because PEA is fat-like and mixes better with food than on an empty stomach. Most products come as capsules of 200 mg to 600 mg, and labels typically suggest spreading the day's amount over two moments. Follow the dose on your product rather than a number you read online, since capsule strengths differ. Loose powder makes splitting easier if you want to build up gradually.
Plan for two to three weeks of consistent daily use before you judge it. PEA is not a product you feel within an hour, and skipping days makes it harder to tell whether it does anything for you. A practical approach: pick a fixed moment, such as your evening meal, and keep the same product and dose for a full month. If you see no reason to continue after that, stop rather than adding more.
Yes, PEA is commonly taken alongside other daily supplements, and there is no known reason it clashes with vitamins or minerals. People often pair it with curcumin or with omega-3 from fish or algae oil, both of which are also taken with a meal, which keeps the routine simple. Add one new product at a time. That way you can tell what is doing what, instead of changing four things at once.
The PEA powder itself is normally made from vegetable palmitic acid, so it is usually suitable for vegans. The capsule shell decides the rest: gelatine capsules are not vegan, while HPMC or pullulan shells are. Because the substance is synthesised rather than extracted from peanuts or eggs, allergen risk comes from the factory and the additives, not from the PEA. Always read the ingredient list and the allergen statement on the pack you are buying.
Three reasons. First, milling: ultra-micronised powder takes an extra production step and costs more than standard powder. Second, dose per capsule: 600 mg capsules look pricier than 200 mg ones until you calculate a month's use. Third, testing: brands that document purity and have batches checked by an independent lab carry that cost. Compare on price per month at your intended daily amount, not on the price on the shelf.
Because it legally cannot. In the EU and the UK, a supplement may only state a health effect if that specific claim has been approved, and no claim has been approved for palmitoylethanolamide. So compliant labels describe the ingredient, the form and the amount, and nothing more. We follow the same rule on this page. It is also why we put our effort into explaining form, dose and purity: those are the things we can verify and you can check.
