Vitality Logic — see what your food is actually missing

Calories are the easy part. The other forty lines aren't.

Vitality Logic logs what you eat and shows every nutrient in it — vitamins, minerals, and the plant compounds most trackers ignore. Free, in your browser, nothing to sign up for.

Eating less makes every nutrient harder to reach

Your iodine requirement doesn't shrink because you're cutting. Neither does iron, selenium, choline or B12. Eat 1,100 calories instead of 2,500 and you need more than twice the nutrient density to land in the same place.

Almost nothing tells you whether you're managing it. Calorie apps stop at protein, carbs and fat, so the day looks fine right up until a blood test says otherwise.

Three numbers from the day in the panel above — a deliberately clean, vegetable-heavy 731-calorie day:

16%of the vitamin D reference
25%of iodine
30%of protein for a 112 kg adult

What it actually does

One screen. Type a food, set the amount, watch forty lines move.

Forty nutrients, not four

Energy and macros, every vitamin, every mineral — each against a reference target, with a bar that shows the shortfall rather than a number you have to interpret.

Upper limits, not just minimums

Supplements make it easy to go too far in the other direction. Zinc, B6, folate, selenium and iron are flagged when you approach the published safe ceiling.

Plant compounds nobody else tracks

Polyphenols, anthocyanins, ergothioneine, glucosinolates and dietary nitrate. Not on any nutrition label, not in any mainstream tracker, and the reason a shiitake and a button mushroom are not the same ingredient.

Real portions

A medium apple, a cup of spinach, a tablespoon of olive oil — actual gram weights per food, so you're not converting anything in your head.

Your own foods

Add anything that isn't there, with as much or as little detail as you have. Local and regional foods that global apps get wrong are already included.

It remembers

Save a meal you eat often and add it in one tap. Copy yesterday. Every logged day stays in your history so patterns show up over weeks, which is the only timescale that matters.

Where the numbers come from

Worth reading before you trust anything on the screen.

  • Standard nutrients come from USDA FoodData Central (SR Legacy), which is public-domain measured composition data, not crowd-sourced entries.
  • Reference targets follow EU nutrient reference values, with EFSA tolerable upper intake levels where they have been established.
  • Bioactive figures are estimates. Polyphenol and ergothioneine content varies two- or threefold with variety, soil and season. Read those lines as direction, not precision.
  • Some foods are incomplete, and the tracker says so rather than quietly reading them as zero. If part of your day has no micronutrient data, it tells you how many grams and which foods.
  • Chromium isn't tracked at all, because food chromium values in every public database are unreliable enough that a number would be fiction.
  • This is not medical advice, and it is not a diagnosis. It adds up what you type and compares it to published reference values. What you do about a gap is a conversation for you and a doctor or dietitian.
