An update on our sweetener

This product is moving to a stevia and monk fruit blend, both natural sweeteners. Until the changeover, products on sale are sweetened with sucralose rather than the thaumatin on the label. Read our update.

Plant-based protein that's actually smooth.

Looking for a delicious, light and creamy plant-based protein that hands-down wins on taste? Nothing Naughty Lean Bean Protein is our best-tasting plant protein yet, made from European fava beans and blended with natural flavours. It suits vegans, anyone avoiding dairy, and anyone who wants plant-based protein without a whey shake.

Why you'll love it

  • 17–21.9g protein per 25g serve, depending on flavour. Fava bean protein provides essential amino acids, and protein is needed for tissue building and repair.
  • A smooth protein powder. It's light and creamy and blends with water or plant milk without the grit. It works in smoothies, yoghurt and baking too.
  • Vegan and gluten free. 100% plant-based, with no dairy.
  • Easier on the soil. Sustainably grown in Europe, fava beans fix their own nitrogen, so they grow without synthetic fertilisers.

Nothing unnecessary

Choose from Vanilla Bean, Chocolate Fudge, Mixed Berry, Banoffee or Natural. Natural is one ingredient: fava bean protein isolate, with no flavour or sweetener added. The flavoured options keep their ingredient lists short, and none have artificial colours, flavours, preservatives or fillers. Each flavour's full ingredient list and nutrition panel is in the product photos.

How and when to enjoy

Mix 25g (about 2 scoops, using the compostable scoop inside) with 200ml water or plant milk. A blender gives the creamiest shake.

  • After training: have a serve as part of your post-workout routine.
  • Daily protein top-up: at breakfast or between meals, to help meet your daily protein needs.
  • Shake it, blend it, bake with it: Natural works in savoury dishes and baking where you don't want any sweetness.

  • Sweetener Update

    Some batches of our flavoured products list thaumatin as the sweetener when it's actually sucralose, which is approved in New Zealand and widely used. These products remain safe to consume.

    We've switched to a new natural sweetener blend, and formulations and labels are being updated as existing stock sells through. Flavours without a note under the add to cart button aren't affected.

    For information about affected products and batches, email help@nothingnaughty.kiwi.nz or read our update.

FAQs

Our Lean Bean Protein is made from protein extracted from fava beans, also known as broad beans. It's plant-based and dairy free. Ours is grown sustainably in Europe and blended in New Zealand.

It contains all nine essential amino acids. Like most legume proteins, it's lower in methionine than animal proteins, so eating a mix of protein foods across the day covers the gap.

Yes, especially if you're avoiding dairy or eating plant-based. Fava bean protein powder produces a light, smooth, and creamy texture when mixed, making it our favourite alternative to whey for taste and texture. Whey and pea proteins have the slight edge on protein per serve, but Lean Bean still provides 17–21.9g per 25g serve, depending on flavour.

Lean Bean has 17g to 21.9g of protein per 25g serve, depending on flavour. Natural is the unflavoured version and sits at the top of that range.

Lean Bean generally wins on taste and texture, but our Premium Pea Protein is the better pick if cost per serve or amino acid profile matters most to you. The protein dose per 25g serve is similar: 17–21.9g for Lean Bean and 17–20g for pea. Fava beans are a little lower than peas in two amino acids, methionine and cysteine. That difference matters less if you eat a mix of grains and legumes through the day. Lean Bean shakes up lighter and creamier, while pea protein mixes best in a blender.
