OstroVit: who makes it
OstroVit is a brand from Poland, best known for sports nutrition and a broad supplement range that includes vitamins, minerals, collagen and omega-3. Because Poland is an EU member, the packs follow the same labelling rules as products made in Lithuania, Latvia or Estonia. Shoppers here usually search for it as "OstroVit" with a country name, such as "OstroVit Lietuva" or "OstroVit Eesti".

Reading an OstroVit label
OstroVit labels are written for the EU market, so the percentages are already NRV values from Regulation (EU) No 1169/2011. The pack text is in Polish, and on our product pages you find the nutrition table in your language. Three habits make the numbers easy to read.
First, vitamin D may be written in IU or in µg. One µg equals 40 IU, so 2000 IU is 50 µg and 4000 IU is 100 µg. The NRV is 5 µg, which is why those doses show 1000% and 2000%. Second, in magnesium products look for the line "magnesium", not the compound: the OstroVit citrate powder lists 2700 mg of magnesium salts of citric acid and below it 378 mg of magnesium, and only the second number counts toward the NRV. Third, many OstroVit formulas combine nutrients, such as vitamin D3 with K2 or magnesium with B6, and each has its own % NRV line.
Original products and where they come from
We are not an official OstroVit distributor. We buy the products from a distributor in the European Union and sell them in the manufacturer's original packaging, with an EU label. The best-before date is shown on every product page.
Questions
Are OstroVit products original?
Yes. They are made by OstroVit and reach us through an EU distributor. We are a retailer, not an official distributor of the brand.
Can I buy OstroVit in Lithuania, Latvia and Estonia?
Yes, in this shop. We sell to customers in all three countries, and each product page shows the price per day next to the pack price.
Is the label in Polish?
The text on the pack is Polish. Our product pages give the composition, daily dose and nutrition table in English, Lithuanian, Latvian and Estonian.
How do I compare OstroVit with another brand?
Match three numbers: the amount of the ingredient per daily dose, how many capsules or tablets make up that dose, and the price per day. We print all three on the product card.
Which OstroVit vitamin D should I choose?
Pick by the dose per day and the format. The range has 2000 IU and 4000 IU, as softgels or tablets, some with vitamin K2. The 4000 IU products are on the vitamin D3 4000 IU page.
Can I combine several OstroVit products?
There is no limit set by the brand. Add up the amounts of each ingredient from every label you use and keep the total below the upper limits on the relevant category page. If you take medicines regularly, ask a pharmacist first.
Which OstroVit magnesium products do you have?
There are four: citrate powder with 378 mg of magnesium per serving (101% NRV), malate powder with vitamin B6 and 150 mg of magnesium (40% NRV), Triple Magnesium capsules with 375 mg across three capsules (100% NRV), and magnesium with potassium and B6 tablets. All are listed on the Magnesium page.
