Does one pack of D3 last 60 days?

Yes, one pack of Vitamīns D3 4000 IU lasts 60 days, because the box holds 60 capsules and you take one a day. That is why the price per 30 days is €1.85, even though the pack itself costs €3.70. The label says to take the capsule with food, for children from 11 years of age and for adults. Each capsule has 100 µg (2000% NRV), so keep to the one capsule a day on the label and do not exceed the recommended daily dose.

Should zinc and selenium be taken every day?

Both labels set one dose a day, so these are everyday products with a clear 30-day price. Cinks 25 mg has 60 tablets in the pack, so it lasts 60 days and costs €1.79 per 30 days. Selēns ACE has 30 tablets, exactly 30 days, and the price per 30 days is €3.05. If you want to compare doses, the multivitamin gives 5 mg of zinc while the single-ingredient product gives 25 mg, so the choice is about dose as much as about price.
