In a classical sense, vitamin D3, the form produced in animals, is not a true “vitamin” because it is produced in the skin from 7-dehydrocholesterol by UV radiation in the range 290 to 300 nm; 7-dehydrocholesterol is produced from cholesterol metabolism. Only when exposure to sunlight is inadequate does vitamin D3 become a vitamin in the historical sense. Further, vitamin D3 is now termed a pro...

tHcy predicted vascular disease more strongly in women than in men, while the reverse was true for fasting tHcy. While post-methionine tHcy was higher in men than in women, in line with previous studies, the percentage change was greater in women, possibly reflecting an overdose of methionine with respect to lean tissue mass. Unlike previous studies, the current paper found only slight evidence...

Vitamins are nutrients essential to human health, and are present in almost all types of foods. In addition to food sources, vitamin supplements are often consumed to ensure adequate vitamin intake, as a customary diet does not always provide sufficient vitamins due to bias and/ or limitation in the choice of foods, or malfunctions in digestion and ingestion. Vitamin supplements are available i...

BACKGROUND: Many physiological processes of mammalian species exhibit daily rhythmicity. An intrinsic relationship exists between fat soluble vitamins (A, D, E and K) and several body functions. Few investigations on the rhythmic pattern of vitamins in domestic animals have been carried out. The present study evaluated the circadian rhythmicity of fat soluble vitamins in the horse. METHODS: Blo...

Vitamins have traditionally been considered as food components that are required in the normal diet to prevent deficiencies. However, a newer concept of the function of vitamins in nutrition has taken them beyond simply prevention of deficiency symptoms. This concept considers that many vitamins, when taken in relatively large doses, have important functions beyond preventing deficiencies. Linu...
