Affiliate disclosure
The site is not yet an affiliate: the application to the Amazon Associates Programme is in progress. No outbound link on this site currently carries an affiliate identifier, and no commission is earned. This page will be updated the day that changes. The paragraph below describes how it is intended to work.
GUIVONIZ intends to take part in the Amazon EU Associates Programme, an affiliate programme designed to let sites earn a fee by linking to Amazon. As an Amazon Associate we earn from qualifying purchases.
In practice: when a link on this site leads to Amazon and a purchase is made, a
commission is paid to us. The price you pay is identical, with or without
our link. Every such link is tagged technically
(rel="sponsored nofollow noopener") and flagged on the page.
That income plays no part at any point in the order of the recommendations or in the level of evidence assigned: the full weighting is published on the Method page. The budgets and availability shown are reference points; only the Amazon page counts at the moment of purchase.
The budget shown — and why it is not a price
This site displays no Amazon price. The bands you see (“20 to 25 €”) are an editorial budget: what a product meeting our criteria usually costs in that aisle.
Two reasons, and the first matters most to you:
1. An Amazon price is wrong by the next day. Amazon changes its prices several times a day, depending on the seller, the stock, promotions and the season. Displaying “22 €” on a page that does not move would give you out-of-date information while looking precise. A band stays true for longer, and answers the only useful question: roughly what does it cost.
2. The Amazon Associates agreement regulates it strictly. It only permits displaying a price if it comes from their official interface and is timestamped. We do not use that interface. So we display no price — rather than displaying one while ignoring the rule.
No figure on this site constitutes a commercial offer or a price commitment. Only the price shown on the Amazon page at the moment you order counts; check it, along with the quantity and the seller, before confirming.
The same goes for availability and for product composition : a manufacturer can reformulate, or change the dose or the packaging, without notice. If you spot a gap between what we state and the Amazon page, tell us: the correction is published with its date.
Health warning
The content of this site is editorial and informational. It is not a diagnosis, not a prescription, not individualised medical advice, and it in no way replaces consulting a health professional.
You must seek medical advice before taking any supplement if you are:
- pregnant, possibly pregnant, or breastfeeding;
- on medication, particularly anticoagulant, antidiabetic, hormonal or psychotropic;
- living with a chronic condition (kidney, liver, cardiac, thyroid, autoimmune);
- before or after surgery;
- a parent wanting to give a supplement to a child or adolescent.
Food supplements are not a substitute for a varied diet and a healthy lifestyle. Respect the doses stated on the packaging and keep products out of reach of children. If you get an unusual symptom, stop taking it and see a doctor.
Personal data
Because there is no cookie to accept. No tracker, no analytics, no advertising, no external font. Nothing you do here is sent anywhere: the engine runs in your browser. A consent banner would have nothing to ask you.
This site collects no personal data on a server: no account, no sign-up form, no advertising cookie, no third-party tracker, no analytics.
The personalisation profile (needs, chronotype, budget, diet, declared precautions, saved
products, recent searches) is stored only in your browser’s local storage,
under the key gx.profile.v1. It is never transmitted. You can
export it as JSON or erase it entirely from the “My profile” panel, or by
clearing the site’s data in your browser.
For how long? It has no expiry date, because it never leaves your machine: it stays until you erase it. It is specific to this browser and this device — on another phone, or in a private window, you start from scratch. Clearing the site’s data deletes it permanently, and we keep no copy: we never had it.
The natural-language search runs locally, in the page: no request is sent to an artificial intelligence service or to a remote server.
The fonts are hosted on this domain, not at Google: no request is made to a third-party server when pages load. Zero external calls until you click an outbound link.
By clicking an outbound link you leave this site: Amazon’s privacy policy then applies, including its own cookies.
