# Fiber-Rich Protein Powders Naughty Boy Previews Source 6, Built on Six Protein Sources By Adam Harrie | Written with AI assistance | Published 2026-10-15 | Business Source: Trend Hunter, https://www.trendhunter.com/trends/fiber-rich-protein-powders References: [stack3d](https://www.stack3d.com/2026/10/naughty-boy-previews-source-6)  Naughty Boy is previewing 'Source 6,' an upcoming protein powder from the UK brand that brings fiber into a category it has recently pushed with flavor-led whey releases. The formula is built for people using protein as part of everyday nutrition, pairing six protein sources with a broader daily-use nutrition angle. Source 6 takes its name from those six inputs, a multi-source setup that typically spreads digestion across faster- and slower-digesting proteins. Naughty Boy's recent protein activity has leaned on taste, with additions such as 'Strawberry Banana,' so the fiber emphasis gives this powder a different role in the lineup. Six protein sources and added fiber broaden the product from a flavor-first supplement into a routine nutrition powder. Added fiber gives Naughty Boy room to compete for repeat daily use, not just one-off flavor interest.
