D3-VITAMIN 500ME tablets N60 – Kvadrat-c

D3-Vitamin 500 IU from Kvadrat-S is a food supplement in tablet form, providing cholecalciferol — the natural form of vitamin D that the human body produces in the skin under the influence of sunlight. Each tablet contains a moderate dose of 500 international units, which makes it a convenient option for those who want a gentle top-up rather than a high therapeutic load.

Vitamin D plays an important role in calcium and phosphorus absorption from food, which in turn contributes to the maintenance of normal bones, teeth and muscle function. It also takes part in the regular work of the immune system. In northern countries such as Estonia and the wider Baltic region, sunlight is limited for a large part of the year, and the skin simply cannot synthesise enough cholecalciferol from October to April. Even in summer, office hours, sunscreen and cloudy weather often reduce natural production. This is why many people in our latitudes look for an additional source of D3 through food supplements.

The cholecalciferol (D3) form is generally considered more effective at raising and maintaining vitamin D levels in the blood than the plant-derived D2 (ergocalciferol). A 500 IU strength is a sensible choice in several situations:

• for adults who already get some vitamin D from food (oily fish, eggs, fortified products) and only need a small addition;
• for those who prefer to divide their intake into smaller portions throughout the week;
• for people who are sensitive to higher dosages and want to start carefully;
• as a maintenance option after a course of a stronger preparation.

The tablet format is practical: it is easy to dose, easy to carry and does not require refrigeration. Vitamin D is fat-soluble, so absorption is better when the tablet is taken together with a meal that contains some fat — for example, breakfast with eggs, yoghurt or a slice of cheese.

A short note of caution: vitamin D accumulates in the body, so it is wise not to combine several D-containing products at once without checking the total amount. If you are pregnant, breastfeeding, taking prescribed medication, or considering higher doses, it is best to consult a doctor or pharmacist and, if possible, check your 25(OH)D blood level. A food supplement does not replace a varied diet and a healthy lifestyle.
