What Actually Separates Them, and How to Check

Reviewed by the Nooria Scientific Advisory Board

There is no register of high-quality supplement brands. No regulator publishes one, and “premium” is not defined for supplements in Swiss, EU or US food law — anyone can print it on a label.

But quality is not actually mysterious. It is decided in four places: which ingredients are allowed in at all, what research stands behind them, what dose they arrive at, and to which standard the formula is made. A brand that can answer all four with specifics is a quality brand. One that answers with adjectives is not.

Here is the whole test in one table, then what each criterion means in practice — using our own formulations as the worked example.

Criterion 1 — Selection: what gets in, and what is rejected

Most formulation decisions are exclusions. The meaningful question is not “what is in this product” but “what was considered and left out, and on what grounds.”

A brand answering this properly can state its funnel. Ours is 3,000 ingredients reviewed, 150 chosen — a rejection rate above 95%. What survives has to clear three gates: a substantive body of clinical research, a chemical form with demonstrated bioavailability, and raw material meeting a published purity specification.

The regulatory floor helps here, in Europe at least. Under Article 4(1) of Directive 2002/46/EC, only the vitamins and minerals on Annex I, in the forms listed on Annex II, may be used in a food supplement at all. That is a positive list: a form not on it is not permitted. Switzerland operates the same logic.

Criterion 2 — Documentation you can read without asking

A brand’s research claim is only worth what its documentation makes checkable. “Backed by science” is not checkable. A named ingredient with a stated mechanism, a declared benefit area and an identifiable formula is.

Our public Ingredient Library publishes every active currently in use — 83 of them across 12 formulas — filterable by benefit area and by formula, each with its function, how it works, and which products contain it. The formulations draw on ingredients supported by more than 269 clinical studies.

Where the evidence sits with a specific characterised ingredient rather than a generic nutrient, we use the characterised ingredient — Cynatine HSN, Pycnogenol, Inavea, Omegia, Lyco — each carrying its own research dossier and its own identity specification. This matters more than it sounds: “collagen” is a category, while a named branded active is a defined material with a traceable file behind it.

Criterion 3 — Dose control, in all three senses

This is where most of the category fails, and it operates at three levels.

The regulatory ceiling. Since 1 July 2020 Switzerland has run a maximum-amount model for vitamins and minerals under the EDI Ordinance on Food Supplements (VNem, SR 817.022.14), derived from tolerable upper intake levels minus estimated dietary intake. The European Union has no equivalent: Article 5 of its own Directive requires EU-wide maximum amounts to be set, and more than twenty years on the Commission has never proposed them. Anyone telling you “made in the EU” guarantees a capped dose is describing a rule that was drafted but never enacted.

The clinical dose. A studied ingredient included below its studied dose borrows the credibility of the research without inheriting its effect. This is why declared per-ingredient amounts matter, and why proprietary blends — legal in the US under 21 CFR 101.36(c) — are effectively excluded in Switzerland and the EU by Article 8 of the Directive, which requires each substance to be declared individually.

The protocol. Dose control does not stop at one bottle. Our stated purpose is to unlock the full potential of each ingredient while preventing overdosing, misuse and unwanted interactions — which is why our protocol never puts more than two products in a single day, and why the eight-week programme runs to an endpoint rather than as an open subscription.

Criterion 4 — What “Swiss made” actually requires

Country of origin is used loosely, so be specific about what it buys.

Manufacturing in Switzerland places a product inside a positive-list system for permitted forms, under published purity criteria, under a defined maximum-amount model, and under a labelling rule requiring per-substance disclosure. Our formulas are developed and produced in Switzerland under those standards, and the range is Halal certified and free from gluten, lactose, GMO and nuts.

What Swiss manufacturing does not do by itself is test any individual product — Switzerland requires no product-by-product authorisation for ordinary supplements. The jurisdiction sets a floor. What a brand builds on top of it is its own responsibility.

How Nooria Builds the Highest Standards Into Its Production 

Selection. We reviewed 3,000 ingredients and selected 150. Each one had to be supported by clinical research and documented scientific characterisation, and was chosen on quality and bioavailability rather than on cost.

Documentation. Every active ingredient we use is published in our Ingredient Library — its function, its mechanism, and the formulas it appears in — filterable by benefit area and by formula, and readable without buying anything.

Dose control. A single Nooria product can combine up to 33 ingredients – and inside each formula every one of them is held at the amount that makes it effective for the objective that formula was built for. The combination within a product is worked out as deliberately as the product itself.
The personalised programme brings together five Nooria products and a Personalised Signature Shot, assembled so that they fit together rather than overlap: no duplication, no overdosing, each one reinforcing the others toward the client’s own objective.
Ease of use is part of the same design — never more than two products in a day. Both are only possible because of the composition and the dosing worked out behind it.

Manufacturing standard. Ingredients with clinically demonstrated efficacy, manufactured and certified in Switzerland.

The individual element. Every programme contains one product made for a single client and nobody else — the Signature Shot, a liquid formula prepared individually. A programme is five Nooria products plus that shot.

Who signs it off. Every plan is reviewed and approved by the Nooria Scientific Advisory Board — a Swiss team of medical doctor, a nutritionist and a pharmacist — so that what the client follows for eight weeks is safe, convenient, genuinely individual and effective.

Frequently asked questions

What makes a supplement high quality?

Four things, all verifiable. First, a real selection standard — what was rejected and why. Second, public documentation of every active, not just a marketing claim of being science-backed. Third, dose control: declared per-ingredient amounts at clinically studied levels, with no proprietary blends. Fourth, a named manufacturing standard rather than a country name used as decoration. A brand that answers all four with specifics is a quality brand.

Are Swiss supplements better quality?

Swiss manufacturing places a product inside a positive-list system for permitted vitamin and mineral forms, under published purity criteria and — since 1 July 2020 — a defined maximum-amount model under the VNem ordinance. The EU has no equivalent EU-wide maximum amounts, despite its own Directive requiring them. That is a genuine floor. It is not a substitute for product-level testing, since Switzerland requires no product-by-product authorisation for ordinary supplements.

What does “clinically dosed” mean?

That the amount in the product matches the amount used in the research the brand cites. It is a stricter claim than “clinically studied ingredient”, which only says research exists somewhere. An ingredient with forty trials behind it, included at a tenth of the trial dose, has borrowed the credibility of those trials without inheriting their effect.

How do supplement brands choose their ingredients?

Well-run formulation is mostly exclusion. A brand with a real standard can state its funnel and its rejection criteria — Nooria reviewed 3,000 ingredients and selected 150. In Europe the regulatory floor narrows the field first: under Article 4(1) of Directive 2002/46/EC, only vitamins and minerals on Annex I, in the forms on Annex II, may be used at all.

Does “pharmaceutical grade” mean anything?

Not as a standard. Neither Switzerland, the EU nor the US defines the term for supplements in food law, so there is no specification a laboratory could test against. General prohibitions on misleading claims still apply. What is defined is compliance with a pharmacopoeial monograph such as Ph. Eur. or USP–NF — a published, testable specification for identity, purity and assay.

Are expensive supplements better than cheap ones?

Price does not track any of the four criteria reliably. Higher price can reflect characterised branded actives, clinically studied doses, third-party certification or small-batch European manufacturing — all of which cost more. It can equally reflect packaging and marketing. The way to tell is to run the four checks; the price alone will not tell you.

Why do proprietary blends matter?

A proprietary blend declares the total weight of a group of ingredients without declaring the split, which makes the product impossible to evaluate — a 1,200 mg blend could be 1,190 mg of one cheap ingredient and 10 mg of the one you bought it for. They are permitted in the US under 21 CFR 101.36(c) and effectively excluded in Switzerland and the EU by Article 8 of Directive 2002/46/EC, which requires per-substance declaration.

How do I know if a supplement brand is trustworthy?

Trustworthiness here is a documentation question. A trustworthy brand publishes what is in every formula, states the standard it manufactures to, names who is accountable for the formulation and their qualifications, and will supply a certificate of analysis when asked. Brands are rarely caught lying in this category. They are usually caught being vague.
