Vitamin D3 - which is best for adults and children? (Ranking 2025)

Vitamin D plays a crucial role in our health and well-being. It affects calcium and phosphate metabolism, which translates to healthy bones and teeth. It also helps regulate the immune system, and studies indicate its influence on the functioning of the nervous system.

Vitamin D, although called a “vitamin,” is actually a prohormone that our body produces on its own, primarily under the influence of sunlight. Unfortunately, our modern lifestyle contributes to deficiencies of this essential vitamin. Working in enclosed office buildings, using (necessary!) SPF creams, and covering the body with clothing all make it very difficult, if not impossible, to obtain adequate levels of vitamin D from sunlight. This is why appropriate, year-round supplementation is so crucial.

Vitamin D from Natu.Care is a well-tested vitamin D3 suspended in safflower oil, a plant known for its numerous health benefits. The convenient, easy-to-swallow capsule will make supplementation a part of your daily, healthy routine, improving your overall well-being.

Vigantol has been trusted by Poles for years. It is an over-the-counter medicine that you can buy at a good price at any pharmacy. It has a simple composition, without unnecessary additives and a small package that will fit into any home medicine cabinet.

• The status of the medicine guarantees us the highest quality of the active ingredients, certainty about the dose and the effect of the preparation until the expiry date.
• Vigantol has an advantage over other over-the-counter vitamin D3 medicines because of the form of the drops.
• The drops are better absorbed by the body and do not need to be taken with a meal (unlike, for example, Vigantoletten, which is in tablet form and is recommended to be taken with a fatty meal).

• The bottle does not have a convenient dispenser. To measure the four recommended daily drops, turn the bottle upside down. The drops dispense slowly. When the liquid runs out, it is difficult to empty the bottle "dry" - a little is left inside.
• If the dispenser becomes clogged, gently tap the bottom of the bottle against the surface (tabletop, table) and then dispense the drops.
• You can use Vigantol for children, bearing in mind that 1 drop is 500 IU, and this is the requirement from the age of 3.
