A Yuka alternative that reads the actual research
Yuka grades products with a fixed nutrition formula and a pre-built additive risk table. NobleBlocks does something different: it searches 350M+ published papers for each ingredient, shows you the studies, accounts for dose, and never charges you to search or asks you to make an account.

Frequently asked questions
What is the best free alternative to Yuka?
NobleBlocks is a free alternative to Yuka that scans food, supplement, and cosmetic labels and shows the actual published research behind every ingredient. Unlike Yuka, search is free and no account is required — you get unlimited scans without signing up.
How is NobleBlocks different from Yuka?
Yuka scores food with a fixed Nutri-Score formula plus a static, pre-built additive risk table, and scores cosmetics from an internal ingredient risk list. NobleBlocks instead runs a live search across 350M+ published research papers for each ingredient, reports how strongly the evidence supports each claim, links the studies by DOI, and flags when risk findings came from doses far higher than real food levels.
Does NobleBlocks account for dose?
Yes. A common criticism of ingredient-risk apps is that they label an ingredient 'high risk' from high-dose animal studies regardless of how much is actually in the product. NobleBlocks surfaces the dose context so you can judge relevance.
Can I check seed oils with NobleBlocks?
Yes. NobleBlocks flags culinary seed oils (canola, soybean, sunflower, safflower, corn, cottonseed, grapeseed, rice bran) along with added sugars, trans fats, MSG, nitrites, carrageenan, artificial colors and sweeteners — and you can set which of these you want highlighted.
Is NobleBlocks really free and private?
Scanning is free and unlimited with no account. Your scan history and preferences are stored only on your device, never uploaded.
