The trial plan to determine whether a daily capsule containing vitamin D(3) (2000 IU), calcium (600 mg), both, or a placebo for 6 months in UAE citizens with evidence of vitamin D deficiency will lead to a clinical benefit. The proposed study will also determine the threshold of vitamin D and calcium intake or levels considered optimal for UAE citizen's health
The proposed study is a two by two factorial, randomized controlled intervention trial. Following informed written consent of eligible subject's blood and urine samples will be taken for measurements of vitamin D, markers of bone turnover and related biochemical variables. Patients who have evidence of vitamin D deficiency will then be randomly assigned to receive daily vitamin D(3) (2000 IU), calcium (1000 mg), both, or a placebo for 6 months. All subjects will have a calcium and vitamin D rich food and other lifestyle modification advises during the study period. Patients will otherwise be managed according to standard practice. Clinical assessment that includes general and self-rated health, bone density, muscle strength, physical activity and dietary intakes will be performed at baseline, and repeated at 3, 6 and 12 months post-randomisation.
Information on other important variables likely to influence vitamin D status including age, reproductive & menopausal history, smoking, medications, adiposity, exposure to sunlight, dietary intake including supplements, skin pigmentation, chronic illness and medications will be collected and adjusted for during the analysis

The purpose of this study is: 1. To compare the response of rickets to calcium with and without vitamin D. 2. To assess whether vitamin D increases calcium absorption in calcium defi...
In recent years, vitamin D has been shown not only to be important for bone and calcium metabolism but also for homeostasis of critical tissues involved in vascular disease in patients wit...
When people eat a meal, some, but not all of the calcium in that meal is absorbed, that is, moved into the bloodstream. When the skin is exposed to sunlight during summer months, Vitamin D...
Vitamin D aids in the body's ability to absorb calcium, it is a vital component in bone formation and break down. Reduced levels of vitamin D can indicate a vitamin deficiency and may depr...
This study is designed as a single-blind RCT in 80 postmenopausal women to compare the effect of immediate administration of daily calcium supplementation (1000 mg calcium) or two daily do...
Vitamin D, a unique vitamin with endocrine function is required in the human body primarily for calcium homeostasis and possibly several other functions. Deficiency of the vitamin is extremely frequen...
Vitamin D Deficiency (VDD) is responsible for a wide spectrum of clinical diseases and vitamin D deficiency prevalence is frightening in most parts of the world including Pakistan. Therefore, suppleme...
The principal function of vitamin D in the maintenance of calcium homeostasis is to increase intestinal calcium absorption. This conclusion was made from studies in vitamin D receptor (VDR) null mice...
Classically, vitamin D has been implicated in bone health by promoting calcium absorption in the gut and maintenance of serum calcium and phosphate concentrations, as well as by its action on bone gro...
Clinical trials are scant and equivocal on whether vitamin D can ameliorate arterial stiffness, particularly in populations at high risk for vitamin D deficiency and cardiovascular disease (CVD). This...
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)
A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. (From Cecil Textbook of Medicine, 19th ed, p848)
A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA). Vitamin A deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin A-rich foods. In the United States it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption. (From Cecil Textbook of Medicine, 19th ed, p1179)
