Which vitamins and minerals should not be taken together?

Short answer: separate iron and calcium into different meals, and do not take a high zinc dose long term without considering copper. Calcium can reduce iron absorption, and 600 mg calcium in one meal can reduce zinc absorption by about 50%. Cinks 25 mg costs €1.79 per 30 days, Magnijs + vitamīns B6 €3.95, Kalcijs 400 mg + D3 5 µg €2.40. Single products cost from €1.43 to €3.95 per month. Delivery is 1–3 working days, free delivery from €20. Prices checked on 9 November 2026.

For products that provide at least 15% NRV, the label can carry permitted claims. Cinks 25 mg provides 250% NRV zinc, so it can say: “Zinc contributes to the normal function of the immune system.” Kalcijs 400 mg + D3 5 µg provides 100% NRV vitamin D3, so it can say: “Vitamin D contributes to the maintenance of normal bones.” Health claims apply in the context of a varied, balanced diet and a healthy lifestyle.

Why is it better not to take iron and calcium in the same meal?

Because calcium reduces iron absorption, especially when both reach the gut with food at the same time. In one study, 300–600 mg calcium reduced iron absorption by 50–60%. In another study, calcium carbonate without food did not inhibit ferrous sulphate absorption, but with food all three calcium forms did. Non-heme iron from food fell by 28% and by 55% depending on the meal. So take iron in a separate meal from milk, cheese and calcium tablets. We have not found a verified number of hours, so we write simply: different meals. Dzelzs + vitamīni un minerālvielas contains 15 mg iron and 145 mg calcium. The 145 mg is below the 300 mg where the 50–60% drop was seen, but we have no own data on this tablet.

Should a high zinc dose be taken with copper?

No, the point is not the same meal; long-term high zinc can affect copper status. The upper level for adults is 25 mg zinc per day. In one study, 2 x 25 mg zinc daily for six weeks reduced copper status. Cinks 25 mg is already equal to that level, so do not combine it with another 25 mg zinc product. If you take 25 mg zinc, count the total zinc from other products. Vissveselibai.lv has Cinks 25 mg as a separate product, which is convenient if you want to control the dose.

Do calcium and magnesium interfere with each other?

There is no proven interference in humans in the sources we checked. We found only a study in rats, so we do not present it as a reason to separate them. Kalcijs, magnijs, cinks un vitamīns D3 contains 500 mg calcium, 250 mg magnesium and 12.5 mg zinc per tablet. Do not add Cinks 25 mg to this tablet or to other zinc-containing products; the zinc amount in each product is stated on its label.

How should I take iron if I drink coffee or tea?

Do not take iron with coffee or tea. In one study, coffee reduced iron absorption from a hamburger by 39%, and tea by 64%. Coffee one hour before a meal had no effect, but one hour after a meal had the same effect as simultaneous intake. So the simplest rule is to separate the iron tablet from coffee and tea. Dzelzs + vitamīni un minerālvielas contains other nutrients, but that does not cancel the coffee and tea advice.

Can folic acid and B12 be taken in one tablet?

Yes, but there is a safety issue that should not be ignored. Large folic acid doses can mask signs of low B12, so if you suspect low B12, do not rely on folic acid alone. The upper level for adults from supplements is 1000 µg folic acid per day. Dzelzs + vitamīni un minerālvielas contains 250 µg folic acid and 25 µg B12, while Multivitamīni un minerālvielas contains 200 µg folic acid and 2.5 µg B12. Vissveselibai.lv also has separate Folijskābe 400 µg at €1.43 per 30 days if you need only one substance.

What should I choose for a simple routine?

Choose separate products if you want to control each dose. Cinks 25 mg, Magnijs + vitamīns B6 and Kalcijs 400 mg + D3 5 µg are a clear combination. Take iron from Dzelzs + vitamīni un minerālvielas in a separate meal from calcium. If you want one tablet a day, Multivitamīni un minerālvielas is a simple option, but zinc and iron are in small doses there. Vissveselibai.lv lets you order without registration, and the 30-day price is shown with each product.
