About Nuvoliv

A supplement shop built to make choosing feel simpler.

Nuvoliv was founded in Croatia in 2026 with a straightforward idea: shopping for supplements should not feel harder than it needs to.

Why Nuvoliv exists

A lot of supplement shopping still feels like the same experience: too many products, too many claims, and not enough help understanding what actually belongs in your routine. Finding supplements is easy. Figuring out which ones make sense for you is usually the messy part.

Nuvoliv was built around that problem. The shop is meant to feel more edited, the product pages are meant to explain more, and the stack pages are there for people who want a more organised starting point.

We also built the AI Advisor for people who would rather not browse everything from scratch. But the idea is not to push everyone into one flow. Some people want guidance, some people just want to shop. The site should work for both.

What we focus on

A more structured way to shop.

01

Clearer product context

People should be able to understand what a product is for, where it fits in a routine, and why they might choose it over something similar.

02

A more curated catalogue

We are not trying to feel like an endless warehouse. A tighter catalogue is easier to navigate and usually easier to trust.

03

Tools that reduce guesswork

The AI Advisor is there to help people narrow things down faster. It is useful, but it is not the whole point of the brand.

04

Less hype, more usability

We would rather explain a product plainly than dress it up with inflated language. Supplements do not need to sound magical to be worth considering.

What Nuvoliv is

A supplement webshop with a bit more structure around it.

At its core, Nuvoliv is still a shop. You can browse products directly, open stack pages built around common goals, read Journal pieces for extra context, or use the AI Advisor if you want a narrower starting point.

We are not trying to force everyone through the same path. Some people already know what they want. Others want more context first. Both approaches should feel natural on the site.

What it is not
  • Not a medical service or diagnostic tool
  • Not a promise that more products are always better
  • Not a brand built only around AI
  • Not a substitute for professional care where that care is needed
How to use the site

Start where it makes sense for you.

Browse the shop

If you already know roughly what you want, you can go straight into the catalogue and compare products without too much friction.

Explore stacks

If you think more in routines than in single ingredients, the stack pages give you a more organised way to look at combinations.

Use the AI Advisor

If you are not sure where to start, the quiz helps narrow the catalogue into a suggested shortlist based on your routine, priorities, and preferences.

Nuvoliv

Clearer choices. Less guesswork.

Whether you want to browse directly or start with a bit more guidance, the aim is the same: make supplement shopping feel easier to navigate.

How it works

Fourteen questions,
one tailored stack.

Your answers map to goals, routine and budget. The AI narrows the catalogue to a reasoned shortlist — with a PDF in your inbox when it's done.

Step 01

14 questions

Goals, training load, sleep, stress, energy, diet and budget. About a minute total.

Step 02

AI builds your shortlist

Products sorted by fit, overlap with your existing supplements and budget tier.

Step 03

PDF to your inbox

Timing notes, reasoning and a daily protocol — sent free, no account needed.

Real outcomes

What people feel,
not what AI does.

Sleeping deeper

"I stopped taking things at the wrong time. The protocol showed me evening was the gap."

More consistent energy

"The afternoon crash is mostly gone. I wasn't missing caffeine — I was missing magnesium."

Less decision noise

"Having a reason for each product made the whole thing easier to stick to."

Calmer mornings

"I had three things I was taking at random. The advisor cut it to two and explained the why."

The first 30 days

What changes
after 30 days.

The advisor gives you a starting point. Here's what that starting point tends to become.

Day 1

You have a starting point

No more browsing noise. A short list with a reason for each product — and timing built in.

Week 1

You know what each product does

The PDF sits on your phone. You know which is for morning, which for wind-down — and why.

Weeks 2–3

You start noticing the gaps closing

Sleep feels heavier. The afternoon stretch is easier. Not dramatic. Just quieter than before.

Month 1

You can tell what's working

If something isn't, you retake the quiz. The stack adjusts. No guessing, no starting over.

The science

Transparent products,
clear reasoning.

The advisor maps your answers to disclosed dosage, category logic and stack overlap. The reasoning is shown every time — no black box, no mystery output.

FAQ

Common
questions.

How does the AI advisor decide what to recommend?

It uses your answers together with product metadata — category, disclosed dosage, format and overlap with current supplements. A selection tool, not a medical assessment.

Is this medical advice?

No. A product-discovery tool — not a substitute for a doctor, pharmacist or dietitian where clinical judgement is needed.

How long does the quiz take?

About a minute. The suggested stack and explanation appear on-screen straight after.

What if I already take supplements?

The quiz asks what you already take, so the recommendation can reduce obvious duplication.

Is it free? Can I retake it?

Yes and yes. Free, no purchase required, retake any time your routine changes.

01 — Our approach

How we choose
what goes in a stack.

i.

We start with the literature

Ingredients are reviewed against published nutrition and physiology literature, and against the EU Register of authorised health claims (Reg. 1924/2006).

ii.

We prefer well-studied forms

Where multiple chemical forms exist, we choose the one with the most documented absorption and tolerability profile — and we say which form is in the bottle.

iii.

We dose in line with research

Daily doses are selected with reference to product format, published literature and applicable EU guidance on use and labelling.

iv.

We test every batch

Every product we stock is verified by an independent ISO-accredited laboratory for identity, potency, heavy metals and microbiological safety. Certificates available on request.

v.

We disclose, fully

No proprietary blends. Every ingredient, form and milligram is printed on the label and shown on the product page.

Subtraction over addition.

We would rather offer fewer, better-documented ingredients than a long list of trending compounds with thin evidence. If we cannot describe an ingredient's role, dose and form in one clear sentence, we will not include it.

"Food supplements are intended to supplement the normal diet — not to replace a varied diet, a balanced lifestyle, or medical advice."
— Aligned with EU Directive 2002/46/EC

What you receive

  • A short list of suggested ingredients
  • The exact form & daily dose for each
  • Suggested timing within the day
  • Plain-language reasoning for each pick
  • What was excluded and why
i.

Profile reading

Your 14 answers are converted into a structured profile — not a diagnosis. The model never infers medical conditions; it identifies categories where your stated diet, training and sleep patterns most often correspond to nutritional priorities described in the literature.

// no health diagnoses · no treatment advice
ii.

Catalogue match

The advisor only ever recommends ingredients already in our catalogue, with their already-fixed doses and forms. It cannot invent a custom dose or pull in a substance we do not stock — it ranks and filters from a closed, EU-compliant set.

// closed catalogue · audited monthly
iii.

Safety filter

Before anything is shown, the result is filtered for known interactions with medication categories you flagged, for pregnancy, and for ingredients whose suitability is age-restricted under EU guidance. Anything uncertain is removed, not softened.

// removes, never softens
iv.

Plain-language output

Each suggestion is paired with a short, non-promotional explanation: which nutritional role the ingredient supports, what the typical research dose looks like, and what your profile suggested as relevant. Suggestions are ordered, not prescribed.

// suggestions, not prescriptions
v.

You stay in control

You can remove any ingredient before checkout, swap forms where alternatives exist, and download a one-page summary to share with your doctor or pharmacist. The advisor is a starting point, not a final word.

// human review encouraged
vi.

What it does not do

The AI Advisor does not diagnose, treat, or replace consultation with a qualified healthcare professional. It does not estimate biological age, predict outcomes, or claim to cure or prevent any disease.

// not a medical device
