Check a food supplement against five points in the paperwork, not by eye and not by reviews. Start with the label: in the EU it must show the daily serving, the amount of each substance per serving and the name and address of the company responsible for the product. Then check the promises on the jar and the factory's standards.
Stivits is an online shop selling supplements under its own brand, not a pharmacy. We sell 105 of our own products, so we will tell you both what checking gives you and what it will not show. A factory certificate is not the same as testing every jar, and you cannot check what is inside a particular jar yourself.
There are five things you can check: the label, the company responsible for the product, the health claims, the factory's certificates, and the ingredients with their doses. All of it is visible before you buy: on the pack, on the product page and on the brand's website. You do not need a lab test of your own.
| What to check | Where to find it | What should be there |
|---|---|---|
| Label | The pack and the pack photos on the product page | The daily serving, a warning not to exceed it, a statement that a supplement is not a substitute for a varied diet, and a note to keep it out of reach of young children |
| Responsible company | The label, the About page on the brand's website | The name and address of the company under whose name the product is sold |
| Claims | The label, the product page, advertising | Only wording from the EU register. No promises to prevent, treat or cure diseases |
| Factory certificates | The brand's website, the section on production | GMP, HACCP, ISO 22000. They are about the factory and its processes, not about what the supplement does |
| Ingredients and dose | The label and the product page | Every ingredient and the amount of each per daily serving. Substances new to the EU only from the EU list |
Check what the dose refers to. Under EU rules, amounts are given per daily serving. If a serving is two capsules, one capsule holds half the dose shown in the table on the label.
In the EU a supplement may carry only health claims from the EU register. The rules are set by Regulation (EC) No 1924/2006, and the list of permitted wording was adopted by Regulation (EU) No 432/2012. The label, presentation and advertising may not attribute to a supplement the ability to prevent, treat or cure a disease. A promise like that on a jar breaks the rules.
The second thing to check in the ingredients is novel ingredients. A substance that was not consumed in the EU before 15 May 1997 can be sold only once it has been authorised and added to the EU list (Regulation (EU) 2015/2283). If you see an unfamiliar substance and the seller does not explain what it is, ask before you buy.
A simple rule: the louder the promise on the jar, the more carefully you should read it. In the EU a supplement may not promise to cure a disease.
GMP, HACCP and ISO 22000 are about the factory and its processes, not about a particular jar. They are standards for production and food safety, and the certificate is issued to the factory. None of them proves what a particular supplement does or what is inside every jar.
What certificates do not prove: that every jar has been tested, or that the supplement will work. So a certificate is no substitute for the full ingredients and dose on the product page.
Checking the paperwork and the label will not show you what is in a particular jar. A factory certificate is not the same as testing every jar. Reviews show the service, not the ingredients. You cannot test the contents yourself. So you check what is available to you: the label, the company, the claims and the factory's standards.
Reviews are useful, but for something else. They show how the order arrived, how it was packed and how the seller responds. A review cannot tell you how much of a substance is in a capsule. Stivits is rated 4.9 out of 5 on Judge.me from 944 reviews (data as of 6 November 2026), and that too is a rating of the service, not an analysis of the ingredients.
If the brand's website says nothing about where testing is done and where the raw materials come from, write to the seller and ask.
Stivits is a brand of the Estonian company HYPERPHARM OÜ (Tallinn, registry code 14669221, Narva mnt 7). The product is sold under its name, and it sells the products itself, with no wholesalers or pharmacies in between. The supplements are made in the EU at a factory certified to GMP, HACCP and ISO 22000:2018; testing is done in the factory's laboratory and in external accredited laboratories.
For example, the page for Vitamin D3 4000 IU shows the ingredients, the dose per serving and how long the jar lasts: 180 capsules for 180 days, €9.89 (price as of 14 November 2026). The pages for Zinc 25 mg and Magnesium citrate 400 mg + B6 work the same way.
The same caveat applies to us as to any brand: our factory certificate is not the same as testing every jar either. How production works and what the standards mean is explained on our About page. The ingredients of every product are open in the catalog.
Skip a supplement if its label has no company and address, no daily serving or no amount per serving, or if it promises to treat diseases. You can check each of these signs in a few minutes before you pay.
Check the label and the paperwork: the daily serving and the amount of each substance per serving, the name and address of the responsible company, health claims only from the EU register, and the factory's certificates. At Stivits, the full ingredients, the dose per serving and how long a jar lasts are on the pack and on every product page.
GMP is good manufacturing practice, following the Food Supplements Europe guide. The certificate covers the factory and its processes and does not prove what a particular supplement does. Stivits supplements are made in the EU at a factory certified to GMP, HACCP and ISO 22000:2018; testing is done in the factory's laboratory and in external accredited laboratories.
You can trust reviews on what they cover: delivery, packaging and how the seller works. You cannot check the ingredients from reviews, and you cannot run a lab test yourself. Stivits is rated 4.9 out of 5 on Judge.me from 944 reviews (data as of 6 November 2026), but that too rates the service. Look at the label and the product page for the ingredients.
Look at the label: in the EU it must carry the name and address of the company under whose name the product is sold (Regulation (EU) No 1169/2011). The factory does not have to be named if it is a different company. Stivits is a brand of HYPERPHARM OÜ, Narva mnt 7, Tallinn, registry code 14669221. The product is sold under its name, and it sells with no intermediaries.
Under Directive 2002/46/EC the label shows the substances that characterise the product, the recommended daily serving and the amount of each substance per serving. It must also carry a warning not to exceed the recommended daily dose, a statement that a supplement is not a substitute for a varied diet, and a note to keep it out of reach of young children.
