Lupin protein is made from sweet lupin seeds, a legume high in protein and fibre and low in starch. It has a neutral taste and is also used in food production.

What it is used for

  • modest effect on cholesterol and blood sugar – weak evidence, small studies

Forms and how they differ

high protein content

lupin flour

more fibre, for baking

When to take it

With meals or between meals, e.g. in smoothies, porridge or baking.

Pairs well with

Watch out for

Lupin is a mandatory labelled allergen in the EU and can cross-react with peanut allergy. With kidney or liver disease, discuss higher protein intake with your doctor.
