The diverse effects of vitamin D in human body became known during the last years. Vitamin D deficiency causes many problems in medical care. Important roles of vitamin D are the regulation of calcium metabolism and the effect on bone metabolism. The authors review literature data on vitamin D deficiency recognized as an important risk factor in the pathogenesis of falls and fractures and they call attention of Hungarian physicians to the importance of vitamin D substitution. Supplementation of vitamin D deficiency is particularly important in the elderly age-group. Orv. Hetil., 2013, 154, 731–736.

It has been estimated that deficiency and insufficiency of Vitamin D affect one bilion people worldwide. Vitamin D deficiency can befound not only in countries with four (4) seasons, but also in countries with sunlight exposure all year long The objective of this studywas to know whether vitamin D deficiency can occur in Indonesia as well and to explore the role of vitamin D in people‘s health, althoughIndonesia is a country in the equator region. To avoid long term negative health consequences 25 hydroxyvitamin D/25 (OH) D serumlevel should be between 30 and 100 ng/mL. The main source of vitamin D is by synthesis at the skin which is exposed to ultraviolet Bradiation. The other source of vitamin D is from food. There are a lot of causes of vitamin D deficiency, for example: decreased vitaminD synthesis, nutritional intake of vitamin D, maternal vitamin D stores and exclusive breastfeeding, mal absorption and decreasedsynthesis or increased degradation of 25 (OH) D. From the above factors, decreased vitamin D synthesis is the main cause of vitamin Ddeficiency. The vitamin D deficiency is estimated and plays an important role in multiple disorders, such as: osteoporosis, fracture, cancer,cardiovascular disease, diabetes mellitus, autoimmune disease and infectious disease. A good strategy in managing vitamin D deficiencyis needed in order to solve the related problems.

The present study was aimed to study the effect of Sublingual Vitamin D3 on Serum Vitamin D level in Vitamin D deficiency patients. This was a cross-sectional and interventional study. All the Vitamin D deficiency patients of age 18-60years and either gender, willing to participate in the study were included. Patients who had greater than 20 ng/ml were excluded from the study. The total number of participants in our study was 200, out of these 111 males and 89 females, the mean age in our study was 51.07 ± 7.39Yrs. All volunteers were given sublingual vitamin D3 (60,000IU) in six doses every fifteen days of follow up for 3 months. The subject’s serum 25(OH)D levels were estimated before and after the treatment of sublingual vitamin D3. There was a statistically significant difference in serum vitamin D3 level before 16.61±6.71 ng/ml and after 35.80±7.80 ng/ml after treatment with Sublingual Vitamin D3. Six doses of 60,000IU of Vitamin D3 sublingual route having improved the role of serum 25(OH)D levels in the treatment of Vitamin D3 deficiency patients.Keywords: Vitamin D3; Sublingual route

Background: Vitamin D exerts multiple pleiotropic effects beyond its role in calcium-phosphate metabolism. Growing evidence suggests an association between hypovitaminosis D and sleep disorders, thus increasing the interest in the role of this vitamin in the regulatory mechanisms of the sleep-wake cycle. Objective: The study aimed to explore and summarize the current knowledge about the role of vitamin D in sleep regulation and the impact of vitamin D deficiency on sleep disorders. Methods: The main regulatory mechanisms of vitamin D on sleep are explained in this study. The literature was scanned to identify clinical trials and correlation studies showing an association between vitamin D deficiency and sleep disorders. Results: Vitamin D receptors and the enzymes that control their activation and degradation are expressed in several areas of the brain involved in sleep regulation. Vitamin D is also involved in the pathways of production of Melatonin, the hormone involved in the regulation of human circadian rhythms and sleep. Furthermore, vitamin D can affect sleep indirectly through non-specific pain disorders, correlated with alterations in sleep quality, such as restless legs syndrome and obstructive sleep apnea syndrome. Conclusions: : Vitamin D has both a direct and an indirect role in the regulation of sleep. Although vitamin D deficiency has been associated to sleep disorders, there is still scant evidence to concretely support the role of vitamin D supplementation in the prevention or treatment of sleep disturbances; indeed, more intervention studies are needed to better clarify these aspects.
