Vitamin D is a fat-soluble vitamin, and unlike water-soluble vitamins it accumulates in the body. Taking high doses regularly without monitoring can lead to an excess, so it is important to take all sources of vitamin D into account at the same time.
- Other supplements. If you are already taking multivitamins, vitamin and mineral complexes or vitamin D on its own in another form, add up the doses. Taking several sources in parallel without counting is the most common cause of unintentionally exceeding the dose.
- Fortified foods. Some dairy products, plant-based drinks and breakfast cereals are fortified with vitamin D. This is a small contribution, but with a high base dose it is worth bearing in mind.
- Long-term use. A short course and months of use are different situations. If you plan to take the drops for longer than a few weeks, it is sensible to discuss this with a doctor or pharmacist in advance, especially if you have chronic kidney disease or a calcium metabolism disorder.
- Pregnancy and breastfeeding. During these periods the need for vitamin D and acceptable doses are determined individually — consult a specialist before you start taking it.
The recommended dose is 1 drop a day or as recommended by a doctor; do not increase the number of drops on your own. Store the bottle as directed on the packaging — oil-based formulas are sensitive to heat and light.
