When life happens

Your week changes.
So does the dose.

Your protocol isn't fixed. It reads what your body's doing and adjusts: up on the hard weeks, down when you no longer need it.

Evidence behind every dose
Supplements · 7 forms

The best forms.
Never the cheapest.

Same name on the label, completely different result in your body. We pick the form you actually absorb, then dose it for you.

Tyttra Magnesium Bisglycinate label
Bisglycinate · not oxide

The form is the difference between deep sleep and an expensive placebo.

Tyttra Vitamin D3 label
Dosed to your bloods

Not a generic 1000 IU for everyone. Your right dose might surprise you.

Tyttra Omega 3 Fish Oil label
EPA / DHA

Take it at the wrong moment and most of it never reaches you. Yours is timed.

Tyttra Vitamin B Complex label
L-methylfolate · active form

There's a genetic reason cheap B vitamins do nothing for half of us. We build around it.

Tyttra Vitamin C label
Split, not dumped

There's a moment in your day when it works three times harder. Your protocol finds it.

Tyttra Zinc Picolinate label
Picolinate · chelated

One of the easiest to get wrong. You only get it when your data asks for it.

Tyttra Iron Bisglycinate label
Bisglycinate · gentle

Pair it right and it works. Pair it wrong and it never lands. We handle the pairing.

Every compound is third-party tested. Every batch is made to EU GMP standards. Every pick has to earn its place in your protocol.

FAQ

to ask.

How can a quiz know what my body needs?

It can't, and we don't pretend otherwise. The quiz gives you a baseline, built from the things that genuinely shift what you need: age, sex, cycle, training load, sleep, stress, diet and what you already take. That's the same reasoning a proper consultation applies, applied consistently. A blood test sharpens it. Your wearable sharpens it again over the first weeks. It gets less generic the longer you're on it, which is the opposite of a bottle you buy once.

Isn't €45 (AED 220 in the UAE) a lot for supplements?

Compare it to what it replaces. Three or four decent bottles already cost that, except you guessed the doses, nobody checked them against each other, and half of each bottle expires unfinished. Here you get the exact forms and doses your data asks for, screened for interactions, in one box. And because it adapts every month, you never keep paying for something your body no longer needs. Founders lock the launch rate for their first 6 months: €35/mo in Portugal and the EU, AED 220/mo in the UAE. Start with the free quiz and see your protocol before you spend a cent.

Do I need a wearable?

No. The quiz alone builds your baseline protocol from your goal, training, sleep, stress and diet. A wearable is what makes it adaptive: it lets us add recovery support on hard weeks and pull the dose back as your numbers improve. We sync with Oura, Whoop and Apple Health.

Can I use a blood test?

Yes, and it's optional. Upload a panel and we refine the protocol against your actual levels instead of population averages. Vitamin D is the clearest example, where the right dose depends entirely on where you're starting.

Is this safe with my medication or condition?

Every protocol is screened against contraindications before you see it. If you're pregnant, breastfeeding, on anticoagulants, have hemochromatosis or autoimmune thyroiditis, or take chronic medication, the affected compounds are removed automatically and flagged for clinical review. It's still wellness guidance, not a medical diagnostic. Always clear changes with your physician.

What if I already take some supplements?

Tell us in the quiz and we exclude them. You won't get a protocol that double-doses the magnesium you already have in the cupboard.

Can I cancel?

Anytime. No lock-in, no cancellation call.

Where do you ship?

Portugal and the EU, plus the UAE. Public launch is September 2026.

What do you do with my data?

We only use it to build and improve your protocol. Nothing else. We never sell it, and you can delete your data and your account at any time.
