FAQ

Everything you are about to ask.

The questions worth asking before you hand anything to a brand you just met.

Does my wearable decide my supplements?

No. Wearable data adds training context and may trigger a protocol review. It does not diagnose a deficiency or independently determine a dose.

Is Tyttra a replacement for protein or creatine?

No. Tyttra is a personalized micronutrient and supplement routine designed to sit alongside appropriate sports nutrition and fuelling.

Do my sachets arrive filled?

No. You receive selected supplement jars and prepare your day-and-night sachets once a week with step-by-step guidance in the app. It takes about five minutes.

Can my coach change my dose?

No. Coaches support onboarding and consistency but cannot select supplements or modify your protocol.

Can my coach see my health data?

Not by default. Any sharing requires your explicit permission, and partners only receive the minimum information necessary.

Are your supplements tested for banned substances?

Independent sport certification is in progress. Competitive athletes subject to anti-doping rules should consult their sporting body and verify each product before use.

Do I need a wearable?

No. The four-minute assessment is enough to build a protocol. A wearable adds training context, which helps us see when a review may be useful. We support Whoop, Oura, Garmin, Apple Health and Health Connect on Android.

How is my protocol decided?

From your inputs: sport, training schedule, goals, diet, sleep, medication and what you already take. Relevant health information and contraindications are screened before anything is included, and every product carries its reasoning in the app.

Can I use a blood test?

Yes. If you have recent results you can add them, and they are taken into account where relevant. They are not required to start.

Is this safe with my medication or condition?

Tell us in the assessment. Medication, conditions, pregnancy and breastfeeding are screened, and anything that is not appropriate is excluded. Tyttra does not provide medical advice, so keep your doctor in the loop for anything clinical.

What if I already take some supplements?

Tell us what they are. Your protocol is built around them so you are not doubling up, and we will say plainly when something you already take covers what we would otherwise include.

Can I cancel?

Yes, anytime, from the app. No notice period, no phone call.

When do I get my first box?

The Founder Pack is a pre-order. Official launch is in October 2026, and founding members are served first. The €35 rate covers your first 6 months.

Where do you ship?

Portugal and the EU at launch, plus the UAE. Elsewhere, leave your email and we will tell you when we reach you.

What do you do with my data?

It builds your protocol and nothing else. We never sell it, and partners never see it unless you explicitly allow it.
