  • 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.
