Every barcode you scan adds its additives to your diary. Over a fortnight the picture sharpens: which E-numbers keep showing up, which weeks drift up, which days drift down. The trend you can't see meal by meal.

We don't show a single grade and call it a day. Once you've been logging for a couple of weeks, the diary aggregates: recurring additives, processed-food drift over the week, which shops fill the trolley with what.
The E-numbers that keep showing up across your fortnight. So you can see whether it's three packs or thirty.
What share of your week is whole and minimally processed, what share is Group 4. So you can see if you're drifting up or down.
On Pro, the analysis looks across the additives in your diary and the reactions you logged after meals. Surfaces candidates you can take to your GP. Not a diagnosis.
How often the Southampton Six, the processed-meat nitrites, and the IARC-flagged colours show up in what you ate. So you can decide what to swap.
Sliceable by supermarket and by meal. Which shop fills the trolley with the most emulsifiers. Which meal is the processed-food spike. Plain numbers.
Every additive we flag links to its library entry, with the FSA, EFSA, IARC or NHS citation on that flag. So the trend is auditable.
The library size, the watchlists we count against, and the regulators we cite when we flag something.
Every E-number we recognise on a UK packet. Each one tagged by category and watchlist membership.
Single days are noisy. A fortnight of consistent logging surfaces the additives that recur, the days that drift.
The free tier covers up to 25 food log entries a day, every additive listed per entry. NutraSafe Pro lifts the cap.
FSA, EFSA, NHS, WHO, IARC. So the count adds up to something you can take to your GP.
Five questions we get most about the tracker. Short answers, sources cited.
Yes. Every barcode you scan into your NutraSafe diary stores the additive list alongside the entry. After two to four weeks of consistent logging the diary surfaces which additives are recurring most often, and how that has drifted week to week.
Most people need two to four weeks of consistent logging before recurring additives become obvious. Single days are noisy. Aggregating across a fortnight smooths out one-off meals and surfaces the lines that show up over and over.
On NutraSafe Pro, the suspected-triggers analysis looks across your reaction log and the additives in your diary and surfaces candidates. This is correlation, not diagnosis. Take the picture to your GP or dietitian.
Free: up to 25 diary logs a day with the full additive list per entry, barcode scanning with a per-product grade, up to 5 reactions, and the public E-number library. NutraSafe Pro at £3.99/month or £34.99/year adds unlimited logging, unlimited reactions, suspected-triggers analysis, the AI Coach, the AI meal scanner, the workout tracker and the fasting timer.
No. We surface what each additive is, what the FSA flags, what IARC has classified, and what published research says. The reader decides what to do with that. If anything in the picture worries you, take it to your GP.
