Log a meal, log how you felt afterwards: energy, mood, gut, skin. Over the weeks the diary spots which ingredients keep coming up before the rough days, so you've got something solid to take to your GP or dietitian. We surface the pattern. They diagnose.

Five categories cover almost everything people bring to us. Each entry takes a few seconds. The aim is a record over time, not a one-off note.
Flat, foggy or wired afternoons. The kind of slump that doesn't match the day's sleep or workload.
Irritability, low mood or anxiety that lifts when you change what you've been eating. Worth recording.
Bloating, wind, reflux, cramping, urgency, looseness. The bit GPs ask about first.
Flare-ups, eczema, hives, itching. Patterns can lag the meal by a day, which is why dated logs matter.
Tension, migraine, hangover-style heads after meals that weren't drinks. Logged with severity.
Pick the category, pick the severity, add a note if you want. The diary already knows what you ate. After a few weeks the suspected-triggers analysis (Pro) starts pulling threads.
Pro feature. Looks across the windows before each reaction and surfaces the ingredients that keep recurring. Not a diagnosis. Something solid for a 10-minute GP slot.
The free tier shows the most recent 5 reactions. Pro lifts the cap and unlocks the analysis.
NutraSafe doesn't diagnose food intolerances or allergies. We can't and we wouldn't try. Food allergy is diagnosed by skin prick tests, specific IgE blood work or supervised oral food challenges. Most non-coeliac, non-lactose intolerances are worked out through supervised elimination and reintroduction with a registered dietitian.
Our job is to make the underlying record easy to keep and easy to share. The diary is what NHS and BDA guidance asks you to bring to the appointment in the first place.
The questions that come in from people about to start tracking. Answers sourced to NHS and BDA guidance.
A dated record of what you ate (ideally at ingredient level), when, the symptoms you experienced and their timing. NHS and BDA guidance for IBS and suspected food intolerance recommend a 7 to 14 day food and symptom diary before any elimination, because the patterns over time are what a clinician needs to interpret.
No, and we don't try to. Food allergy is diagnosed by a clinical specialist using skin prick tests, specific IgE blood tests or supervised oral food challenges. Most non-coeliac, non-lactose intolerances are worked out through supervised elimination and reintroduction with a registered dietitian. Our role is to make the underlying record easy to keep and easy to share.
It surfaces correlations across your logged meals and reactions. For example, it might show that you logged a reaction within three hours of eating a particular ingredient four times in the last 30 days. It doesn't call that ingredient your trigger. It surfaces the data your GP, dietitian or registered allergist can interpret in clinical context.
Free covers logging up to 25 foods per day, barcode scanning with the additive flag, and your five most recent reactions. NutraSafe Pro is £3.99/month or £34.99/year on iOS and unlocks full reaction history, the suspected-triggers analysis, allergen warning detail on barcode scans, and processed-food and NRV insights.
UK retail items scan via the barcode straight from supermarket and own-brand catalogues. Pre-packed for direct sale items, such as a sandwich made on site or a salad assembled at the counter, carry a full ingredient list under Natasha's Law (2021), but no barcode, so we provide manual ingredient logging for those. Restaurant meals can be logged at meal level with as much ingredient detail as you have.
Two to four weeks is the typical range. NHS and BDA both frame elimination and reintroduction protocols around a 2 to 4 week observation window. A week is usually too short to spot anything but the clearest triggers; a month covers enough day-to-day variation to surface quieter patterns that a clinician can work from.
