Pea protein – a vegan protein source
Pea protein is a plant-based protein isolate derived from yellow split peas (Pisum sativum). Alongside soy, rice, and hemp protein, it's one of the most common plant-based protein sources. It's primarily used as an alternative to animal protein powders like whey, as it's naturally lactose-free, gluten-free, and generally vegan.
Brief overview
Feature | Information |
|---|---|
Raw material | Yellow split peas (Pisum sativum) |
Protein content (isolate) | approx. 80–90 g per 100 g of powder |
Origin | Mostly Europe or Canada |
Production process | Dry or wet extraction, without chemicals |
Suitable for | Vegan, gluten-free, and lactose-free diets |
Solubility | Easily soluble in water, plant-based drinks, and smoothies |
Taste (natural) | Slightly earthy, so often available in flavoured versions |
How is pea protein made?
To make it, the peas are first ground into flour. The protein is then separated from starch and fibre using a wet or dry extraction process and made into a concentrated powder (concentrate or isolate). Isolates have a higher protein content than concentrates because more carbohydrates and fats have been removed.
Composition: Amino acid profile
Pea protein contains all nine essential amino acids. It typically has a comparatively high content of arginine, lysine, and branched-chain amino acids (BCAAs). The level of the sulphur-containing amino acid methionine is lower compared to animal protein sources – one reason why pea protein is often combined with other plant-based protein sources (e.g., rice or hemp protein) in vegan diets to provide a broader range of amino acids.
Who might consider pea protein as an option?
Pea protein is primarily sought after by the following groups:
- People who follow a vegan or vegetarian diet
- People with lactose intolerance or a milk protein intolerance
- People with a gluten intolerance (pea protein is naturally gluten-free)
- People who, out of personal preference, want to switch to plant-based protein sources instead of animal-based ones

How to use
Pea protein powder can be mixed into water, plant-based drinks, smoothies, or dishes like porridge. The manufacturer's recommended intake as indicated on the packaging is the authoritative guidance.
Frequently Asked Questions About Pea Protein
Yes, pea protein is made exclusively from peas and is therefore naturally plant-based. For flavoured products, it's worth checking the full list of ingredients, as some flavourings or additives may not be vegan.
Peas are naturally gluten-free. However, if you have an intolerance, it's still advisable to check with the manufacturer for any potential cross-contamination.
Whey protein is made from cow's milk and contains lactose and milk protein. Pea protein is free from lactose and milk protein, making it a suitable option for individuals with related intolerances or those following a vegan diet.
Concentrates typically contain 55–80 g of protein per 100 g, while isolates, thanks to an additional purification process, usually contain 80–90 g of protein per 100 g, with a lower carbohydrate and fat content.
practice, pea protein is often mixed with rice, hemp, or sunflower protein to achieve a broader range of amino acids.
