The objective of this study is to evaluate and compare the bioequivalence between a single oral dose of vitamin D3 gummy vitamin versus vitamin D3 tablet in healthy adults.
The objective of this exploratory pharmacokinetic research study is to demonstrate that both caplets and gummies provide an effective dose of ascorbic acid in healthy adults.
The purpose of this study is to determine the average dosage of oral vitamin D supplementation to maintain optimal vitamin D levels in the body and to see if there are differences in the r...
While there have been a considerable number of studies on the impact of additional vitamin D in the diets of hens on the resulting egg vitamin D content, the effect of consumption of such ...
The investigators want to make sure that people get the right dose of Vitamin D treatment. They will therefore investigate how skin colour, body mass index, ethnicity, vitamin D binding pr...
Treatment of vitamin D deficiency in adults requires adequate diagnosis based on the rigorous definition of the disease. Recently, it has been reported that assessment criteria for vitamin D deficienc...
Complementary medicines are a multibillion-dollar industry of which vitamin supplements are an important component. Most of the claims of benefit are not evidenced-based, and vitamin supplements may b...
The determinants of serum vitamin D seems to be the environmental factors (dietary and supplementary intake and exposure to ultraviolet light) and genetic factors. We aimed to study the relationship b...
Vitamin D regulates adipokine production in vitro; however, clinical trials have been inconclusive. We conducted secondary analyses of a randomized controlled trial to examine whether vitamin D supple...
Vitamin D is conventionally known as sunshine vitamin and is synthesized endogenously in sunlight. Vitamin D is known to be a key regulator of bone metabolism, the function of genes, and essential for...
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.
OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.
A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
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)
