What it does for the body.
Cell signalling
The body uses EPA to form signalling molecules involved in normal physiological processes.
Heart function
Together, EPA and DHA contribute to normal heart function at a daily intake of 250 mg.
When to pay particular attention
Needs are not identical.
Age, life stage, activity and the rest of the diet can change what deserves attention.
- People who eat little oily fish
- People comparing fish and plant omega-3 sources
- Anyone reading an EPA + DHA laboratory result
Food first.
Sardines, herring, mackerel, salmon, trout and other seafood provide EPA. Plant foods provide ALA rather than meaningful amounts of EPA.
How do we measure it?
One value. Three useful views.
Per 100 g
A standard basis for comparing different foods and pack sizes.
Per serving
The quantity associated with a stated serving. Serving sizes can differ.
Per package
The calculated total when the entire package is the relevant amount.
We show where every number comes from.
Diplomats Product Nutrition
The value belongs to the exact product, recipe and measurement basis shown. We present it as the product’s number.
Reference Nutrition Data
A scientific food database provides a range for a comparable fish. We mark it with an asterisk and never present it as a laboratory result for the product.
Nutrition Knowledge
Primary health and food-science sources explain what a nutrient does, who should pay attention and how the number is used.

Why does epa in food matter?
Works with DHA: EPA and DHA are commonly considered together in food guidance and research. Cell signalling: The body uses EPA to form signalling molecules involved in normal physiological processes. Heart function: Together, EPA and DHA contribute to normal heart function at a daily intake of 250 mg.
Can a value be assumed from the fish species?
No. Diplomats separates general food education from facts verified for a particular recipe, serving and product.
What does “per 100 g” mean?
It is a standard comparison basis. It lets visitors compare products of different pack and serving sizes using the same amount of food.
