Plant-based protein powder has come a long way, but most options still blend multiple protein sources, add sweeteners to mask the taste, and bulk the mix with gums and fillers to improve texture. The result works for marketing but not always for the person using it daily.

Lupin Gold is a single-ingredient plant-based protein powder made from sweet lupin isolate. One ingredient. ~90% protein per serve. A complete amino acid profile including all essential amino acids (EAAs) and branched-chain amino acids (BCAAs). No soy, no dairy, no stevia, no gums, no fillers.

Because it is naturally unflavoured, this plant protein isolate works across the full range of everyday food, from smoothies, oats and yoghurt bowls to baking, sauces and cooking, without altering taste or texture. It is plant protein that fits into real food rather than replacing it.

Comparing plant protein powder against whey and soy? Lupin isolate is a clean single-source alternative with a digestibility profile commonly associated with easy tolerance, even for people who find blended plant proteins hard on their gut. If you specifically need dairy-free protein powder, or a flavourless protein powder, we have a page for each.

Lupin Gold is Australian owned and packs every batch in Western Australia, with orders dispatched domestically. We pack it ourselves rather than handing that to a third party, which is how the single-ingredient claim stays true from the isolate through to the pouch.

received 12 months supply and it is awesome!

I won an awesome prize! Been using it for 1 week now. Really like the taste, most mornings I mix it in my porridge and it ads a sweet flavour. Even for a natural flavour it is still nice just with milk, no need to add anything. Really enjoying it and looking forward to seeing benefits after further use. Once again thanks heaps for the years supply 👍

Excellent for that burst of protein.

This company has been fabulous to deal with. I had a bit of a hitch at the start but everything was fixed up in no time at all. Since using the product, I'm sold on it. It is very dissolvable, so it's lovely and smooth. I add cocoa, vanilla or fruit to it and blend it into a delicious smoothie. Thanks Lupin Gold!

Tastes great

I love this. I actually have withdrawal symptoms if I don't have it. I add it to some milk and a couple of seconds in the blender and bingo..

Absolutely loving it so far

Absolutely loving it so far, other protein powders I have tried (I’ve tried a lot) have tasted grainy and left me feeling bloated afterwards but this one doesn’t at all!

Plant Protein Isolate FAQs

Answers to common questions about clean, plant-based protein isolate and how to use it.

Plant protein isolate is a highly concentrated form of plant protein with most carbohydrates and fats removed. Lupin Gold uses sweet lupins to produce a clean, high-protein isolate suitable for everyday use.

Yes. Lupin protein naturally contains all essential amino acids, making it a complete plant protein. Our amino acid profile is also extremely well-balanced.

Dairy free, yes: no lactose, whey, casein or milk-derived ingredients. Gluten free, not yet: our current batch contains trace levels of gluten and is not suitable for people with coeliac disease or gluten intolerance.

Our next batch has returned no detectable gluten readings and will be independently tested. Sign up to be notified.

Lupin Gold is a highly digestible protein isolate that contains naturally occurring Lupin fibre (super fibre) with no added gums or sweeteners, which many people find gentler than blended plant proteins.

This protein isolate works well in smoothies, oats, yoghurt bowls, baking and cooking. Its neutral taste makes it suitable for both sweet and savoury recipes.
