How it works

Your body changed. Here’s how we keep up.

Four steps, one formula, and a rhythm that adapts as you do. No guesswork. You tell us what’s going on, we build and rebuild around it, and every month you see exactly what changed.

How it works

How it actually works. Four steps, every month.

The named system behind what you just watched. A monthly loop that keeps your Formula honest about the body you have now.

Step 1

Check-In

We start with what changed, not a form. What feels different since last month?

Step 2

Formula

Built around the body you have now, from your inputs, your wearable, and your blood markers.

Step 3

Monthly Rebuild

Reviewed every month, rebuilt when your Check-In calls for it. When it changes, doses shift and ingredients come and go as you do.

Step 4

This Month Changed

A plain note showing what shifted, why it mattered, and what we adjusted.

Your daily rhythm

Your body doesn’t need the same things
at 7am and 10pm.

When you take your supplements matters as much as what you take. So your formula comes in two parts, built for two different jobs.

Morning

A morning powder

Built to support energy for the day ahead.

Evening

An evening shot

Built to support recovery and sleep as the day winds down.

The split is deliberate, not decorative.

Some ingredients do their work in the evening, some in the morning, and some cancel each other out if taken together, so we separate the ones that compete.

It’s also why the morning formula is a powder. A capsule is a fixed dose. A powder lets us set each ingredient to the exact amount your data calls for.

The precision is the point. You don’t need to work out what blocks what. We do the formulation, and you just drink it, morning and evening.

What it reads each Check-In

Every rebuild starts
with what your body is telling us.

Each Check-In, three things feed the rebuild: what you tell us, what your wearable shows, and what your blood markers say. The more your data shifts, the more the formula moves with it. Then we reassess every month.

01

What you tell us

Your medications, how you feel, and your goals.

02

Your wearable

Connect it in the quiz. Your sleep, activity and recovery become inputs.

03

Your blood markers

Add them in the quiz, so the formula reflects your actual biology.

Real inputs in. A formula that’s genuinely yours, reassessed every month, rebuilt when it counts.

Proof

This is what adaptation
looks like in your hands.

Not a claim on a page. The note that arrives with every shipment, in plain language.

Every month you see exactly what moved in your formula and why. If nothing has changed, the note tells you that too. This is the show-don’t-tell at the heart of the system.

Watch the Formula rebuild.

This is the heart of how Personally works. A quick Check-In, then your Formula responds, in front of you. It's an illustration of the monthly rebuild, not a medical assessment. Your real Formula is built in the quiz from your full picture.

Check-In: what feels different this month?

Tick anything that fits. The Formula on the right updates as you go.

Medication-aware screening ran. Because you told us a medication changed, we screened your declared medications for relevant supplement interactions and nutrient-depletion considerations before rebuilding. Most supplement brands don't ask. We do.

    How your formula actually behaves.

    What if my formula isn't right for me?

    You review every formula in the 7 days before it ships, and it's rebuilt every month around what's changed. So nothing is set in stone, and nothing ships that you haven't seen.

    Is more always better?

    No. The aim is the right dose for you, not the highest one. More of an ingredient isn't more benefit, and some have a point past which it stops helping.

    Will I actually feel anything?

    Some people notice changes in areas such as energy, sleep or wellbeing within the first month, especially where the formula addresses a clear nutritional gap or transition. Others may not feel an obvious change. What we promise is an evidence-informed formulation method that adjusts as your dynamic biomarkers do.

    What actually arrives, and when?

    Your Welcome Kit: a morning powder you mix into a drink, an evening shot, a shaker and a scoop. You just drink it, morning and evening. It arrives in about 5 to 7 days, then a rebuilt formula follows each month.

    How long until I see my formula?

    A preview in about two minutes. Your full formula in about fifteen.
