What you're looking at is a design mockup of Body+, not a live product. Nothing here is for sale, no formula you build will be made, and the numbers you'll see are illustrative.
Pick what you're actually after. Each one is read by a different medical specialty — the plain word is the goal, the small print is the doctor behind it.
Question 2
The four numbers a clinician would ask for first
Reference ranges are not universal — ferritin and haemoglobin bands differ by sex, and dosage scales with body mass. Without these, any "personalized" formula is guessing. Most quizzes never ask.
Sex at birth
Used for the reference bands, which genuinely differ. Not used for anything else.
We ask for sex at birth because that is what the clinical reference ranges are built on. It says nothing about how you identify, and we don't use it for anything but the bands.
Question 3
Which of these is closest to your week?
We're after the physiological load your week creates — the label is just the quickest way to find it.
Question 4
How hard is a normal week, physically?
Training volume drives sweat loss, iron turnover and magnesium demand more than almost anything else you'll tell us.
Question 5
Sleep and daylight, honestly
These two together predict vitamin D and magnesium status better than any other self-reported pair.
Question 6 — optional
Do you have a recent blood panel?
This is the only question that changes what the model actually knows. Without it, we estimate your markers from everything above. With it, we measure them. Skipping it still gets you a formula.

Your draft formula
Built from estimates
Here's what the model produced. Every marker below is an estimate inferred from your answers — the hatched band is the range you most likely sit in, not a measurement.

The precision upgrade
The model is guessing at three markers it could be reading. A panel replaces every hatched band above with a measured value — and the formula gets rebuilt around what's actually out of range for you, not what's statistically likely.
Measured, not estimated. Every marker above came from your upload. Two are below reference, and the formula on the right is built around those two specifically. Re-upload a panel in 8–12 weeks and it gets rebuilt again.
Draft formula — dailyStarting stack
Vitamin D32000 IULow daylight exposure plus an indoor week — the most commonly low marker in this profile.
Magnesium glycinate400 mgTraining load and sleep quality both draw on magnesium. Glycinate for tolerability at this dose.
Electrolyte blendAround sessionsSodium-forward, for sweat loss on anything over 90 minutes.
Vitamin B12500 µgSupports normal energy-yielding metabolism and normal red blood cell formation.
