Vitamin D is an oil-soluble vitamin, which is known as the sunshine vitamin. UV rays activate a certain form of cholesterol in our body and change it to vitamin D. If enough sunshine is available only during summer, which is our case in Estonia, it is advised to use vitamin D supplements from September until May.

The most important role of vitamin D is to regulate the absorption of calcium in our bodies. The main factor in calcium absorption is the active form of vitamin D, calcitriol. In addition our bodies need vitamin D for blood clotting and heart rate support, decreasing the risk of infection and diabetes, development of bones and teeth and for better absorption of phosphorus.

10 μg, 400 IU


10 μg, 400 IU

These are the daily recommended values for vitamin D in Estonia, but these values are often not enough to maintain and achieve the optimal level. If your level of vitamin D is at least 80 nmol/l, you should use daily at least 25 μg, 1000 IU of vitamin D, to maintain the level. If your vitamin D level is below 80 nmol/l, you should use daily 50-125 μg, 2000-5000 IU depending on the level. Read more from here, how much vitamin D you should use.
