| Abstract | In the recent past, many studies have been published on the association between vitamin D and bone health or the risk of various chronic diseases. Thus, the D-A-CH reference values [D-A-CH arises from the initial letters of the common country identification for the countries Germany (D), Austria (A) and Switzerland (CH)] for the intake of vitamin D have been revised based on a critical review by the German Nutrition Society. Both dietary intake and endogenous synthesis contribute to the body's vitamin D status. Since different factors modulate the extent of endogenous vitamin D formation, quantification is hardly possible. Therefore, the new reference values for vitamin D intake are specified for a situation in which endogenous synthesis is completely missing. Based on the findings of the critical review, serum 25-hydroxyvitamin D concentrations of 50 nmol/l or higher are considered an indicator of an optimal vitamin D status. When endogenous synthesis is missing, adequate vitamin D intake is estimated as 20 µg per day for children, adolescents and adults. Dietary vitamin D intake from habitual diet is not sufficient to achieve this value. This gap has to be covered by endogenous vitamin D synthesis and/or additional intake of vitamin D. It is clearly stated that the desired vitamin D supply can be achieved without using vitamin D supplements by frequent sun exposure. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
