The Insights view shows your week against the UK NRV in a single read. Coral bars are sitting below target, sage bars are tracking, yellow are over. The diary tells you which food moved which bar.
NRV stands for Nutrient Reference Value. The figure UK food labels use to show how much of a vitamin or mineral one portion gives you. They replaced the older RDA. 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, so when you see "Iron 48% of NRV" on your week, that's translatable to anything a UK label or NHS page says.
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.
NHS recommends a 10µg daily supplement for all UK adults through the darker half of the year. The diary tracks dietary D so you can see whether food alone is closing the gap. (It almost never is, north of Manchester.)
SACN flags iron as one of the most common UK shortfalls for women aged 19 to 49. The National Diet and Nutrition Survey keeps showing it. The diary surfaces your weekly number against the 14mg NRV.
B12 is mostly in animal foods. Vegans and many vegetarians need to source it from fortified foods or a supplement. NHS recommends absorption checks for adults over 65 who feel persistently tired.
The 2019 to 2023 National Diet and Nutrition Survey showed average intake below the 375mg NRV for most adult groups. Nuts, seeds, wholegrains, dark greens. Easy to add once you can see the gap.
The micronutrient numbers move as you log. Barcode or photo. Daily, weekly, monthly. Same diary as the food, the reactions and the training.
A, D, E, K, C, the B complex (B1, B2, B3, B5, B6, B7, B9, B12) and choline. SACN micronutrient list, scored against UK NRV.
Calcium, iron, magnesium, zinc, iodine, selenium, copper, manganese, phosphorus, potassium, chloride, chromium, molybdenum.
The same figure on UK food labels. Not US Daily Values. So percentages translate to anything a UK GP, dietitian or NHS page references.
Daily totals are free. Weekly and monthly NRV trend views are Pro. So you can see whether a low day is a one-off or a pattern.
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 13 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.
Daily vitamin and mineral totals are on the free tier. Weekly and monthly NRV trends are Pro at £3.99 a month or £34.99 a year. Try the free tier first.
