The full SACN micronutrient list, scored against the UK NRV. Every food you log adds to the totals, daily, weekly and monthly. We don't round up to a marketing number.
Vitamins. 14 tracked against the UK NRV, with the reference amount for a typical adult.
Minerals. 13 tracked against the UK NRV, alongside the daily reference amount.
The Insights view shows your week against the UK NRV in a single read, so you can spot the nutrients you keep falling short on without doing the maths yourself.
Every food you log adds to your running vitamin and mineral totals. Insights rolls those up against the UK Nutrient Reference Value and marks each one as under target, on track, or over for the week. A single vitamin that reads low on one day is usually nothing; the same nutrient sitting under target across the week is the pattern worth acting on.
The diary keeps the link back to the food, so when a nutrient is running low you can see which meals were carrying it and which days it dropped off. That is the difference between a calorie count, which tells you how much you ate, and a vitamin tracker, which tells you what was missing from it. Weekly and monthly NRV breakdowns are a NutraSafe Pro feature (£3.99 a month, iOS).
NRV stands for Nutrient Reference Value. It's the figure UK food labels use to show how much of a vitamin or mineral one portion gives you. NRVs replaced the older RDA on UK packs. We score against the UK NRV, not the US Daily Value.
The percentage on the front of a UK packet is a percentage of NRV. We use the same figure across the diary, daily, weekly and monthly, so when you see "Iron 48% of NRV" on your week it lines up with anything a UK label or NHS page says. We don't quietly switch to US Daily Values. The headline figures come from the NRVs retained in UK law, with SACN's micronutrient reports and NHS Eatwell for the UK-specific work on vitamin D, iron and folate.
This matters more than it sounds. The UK vitamin D NRV is 10µg, where the US Daily Value is 15µg. The NHS recommends a 10µg supplement from October to March for all adults. If an app scores you against the US 15µg, a normal UK intake reads as a bigger shortfall than it is against UK guidance. NutraSafe uses the UK figure throughout, and keeps the source on the number, so what you make of the gap is your call, not a nudge to buy anything.
NHS and SACN flag these as the most common UK shortfalls. Logging your food for a couple of weeks tells you whether they apply to you, before you spend on supplements.
The NHS recommends a 10µg daily supplement for all UK adults through the darker half of the year, because we make little from sunlight then. The diary tracks the dietary vitamin D in what you log, from oily fish, fortified spreads and eggs, against the 10µg NRV, so you can see whether food alone is closing the gap. (It rarely is, north of Manchester.)
SACN flags iron as one of the most common UK shortfalls for women aged 19 to 49, and the National Diet and Nutrition Survey keeps showing it. The diary surfaces your weekly number against the 14mg NRV as you log red meat, pulses, leafy greens and fortified cereals. Vitamin C in the same meal helps absorption, and because both sit in the same diary, that pairing shows up in your totals.
B12 is mostly found in animal foods, so vegans and many vegetarians need to source it from fortified foods or a supplement. The NHS suggests absorption checks for adults over 65 who feel persistently tired. Log a normal week and the diary shows your B12 against the 2.5µg NRV, which makes it easy to see whether a plant-based day is leaving you short before it becomes a longer pattern.
The 2019 to 2023 National Diet and Nutrition Survey showed average intake below the 375mg NRV for most adult groups. It comes from nuts, seeds, wholegrains and dark greens, and it's easy enough to add once you can see the gap. The diary tracks magnesium against the NRV the same way it does the rest, so a persistent shortfall stands out rather than hiding behind your calorie count.
The eight questions we see most by email and inside the app. If yours isn't here, drop us a line from the support page.
NRV stands for Nutrient Reference Value. It's the figure UK food labels use to show how much of a vitamin or mineral one portion gives you as a percentage of a typical adult's daily need. NRVs replaced the older RDA (Recommended Daily Allowance) on UK packs. They reference EU values retained in UK law plus SACN's UK-specific work.
You can see vitamin and mineral counts as you log on the free tier, up to 25 food entries a day. NutraSafe Pro lifts the daily cap and unlocks the weekly and monthly views with day-by-day NRV breakdowns.
14 vitamins and 12 minerals against UK NRV. Verified in our app code (NutritionModels.swift). We tell you the count rather than rounding up to a marketing number.
No. Most people log consistently for one to two weeks to see where they're short, then dip back in periodically (a week every couple of months) to check habits haven't drifted. The goal is awareness, not obsession.
Yes. We use UK Nutrient Reference Values, the same numbers UK food labels carry, not US Daily Values. So the percentages you see line up with the figure a UK GP or dietitian would reference.
Yes. The free tier on iOS shows vitamin and mineral totals as you log, capped at 25 food entries a day. Pro removes the cap and adds the weekly and monthly NRV views, plus the AI Coach, fasting and workouts.
Almost always a data-coverage issue rather than a real zero. Own-brand supermarket items sometimes carry less complete micronutrient data than branded equivalents. Try logging a branded comparator for the same food and see if the number moves.
NHS and SACN flag vitamin D (October to March, the NHS recommends a 10µg supplement for everyone), iron (especially women of reproductive age), vitamin B12 (vegans and older adults), and magnesium (commonly under the NRV on UK diets). The diary makes the trend visible without you doing the maths.
