Vitamin D plays a very important role in the human body as it contributes to the maintenance of normal bones and normal function of the immune system. Numerous reports showed high prevalence of low vitamin D intake and vitamin D deficiency in Europe – particularly during the winter season, indicating the importance of vitamin D supplementation.
Vitamin D, also called the “sunshine vitamin”, is formed by the human body when exposed to sunlight (UVB). With sufficient exposure* to the sun’s rays in the summer, people in moderate climates have sufficient amounts of vitamin D. Unfortunately, different seasons come with different amounts of sunlight, which sometimes makes it impossible for us to meet our daily needs for this vitamin. Therefore, we must supplement it with an additional input, something that is also recommended by health professionals. As only a few foods are rich in vitamin D, supplementation in the form of dietary supplements is recommended.
*At least 15 minutes a day, provided our skin is not protected by clothing and/or sunscreens.
There is some confusion regarding the dosages, as different associations recommend different amounts of daily intake of vitamin D. Question about appropriate dosing and formulation of vitamin D supplementation therefore arises. To get a more accurate answer to that question, Valens initiated a study about treating suboptimal vitamin D status that was conducted in Slovenia. Our goal was to prove efficiency of treating suboptimal vitamin D status with 25 µg (1000 IU) of vitamin D3 per day using different vitamin D3 (cholecalciferol) formulations, which are most commonly used in supplements.Two Valens products were used in the trial: Valens D 1000 oral spray (water-based) and Valens D-Natural (oild-based). Both products were proven to be efficient in treating suboptimal vitamin D level.
Vitamin D is especially important for babies, children and kids – paediatricians recommend vitamin D supplementation should start at birth. There are also many other studies that have proven the problem of vitamin D deficiency in older people, who are especially advised to add vitamin D with supplements. Our clinical study also showed high prevalence of vitamin D deficiency in all age groups, indicating importance of vitamin D supplements.
