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...

Certain epidemiological and experimental studies suggest that n-3 fatty acids and folate can reduce blood pressure (BP). We investigated the effect of a daily supplementation with dietary doses of B-vitamins or n-3 fatty acids for 5 years on BP in patients with a history of CVD who participated in the Supplémentation en Folates et Omega-3 trial. The patients (n 2501; 1987 men and 514 women) wer...

There is some evidence showing an inverse correlation between dietary sources including natural antioxidant vitamins and the risk of cardiovascular disease (CVD). The aim of this study was to evaluate the effect of dietary antioxidants on oxidative stress in CVD patients. This study was carried out on 31 CVD patients and 63 healthy individuals. Nutritional status and dietary antioxidant vitamin...

Peripheral parenteral nutrition (PPN) solutions contain amino acids, glucose, and electrolytes, with or without some water soluble vitamins. Peripheral venous catheters are one of the causes of catheter related blood stream infection (CRBSI), which requires infection control. In Japan, PPN solutions have rarely been prepared under aseptic conditions. However, in recent years, the necessity of a...

The prevalence of asthma and other atopic disorders continues to increase worldwide. Examination of the epidemiologic patterns has revealed that this rise has occurred primarily in western, industrialised countries and countries transitioning to this lifestyle. While many changes have occurred in human populations over the years, it has been hypothesised that some of the relevant changes that h...

BACKGROUND The role of vitamins in the combat of disease is usually conceptualized as acting by modulating the immune response of an infected, eukaryotic host. We hypothesized that some vitamins may directly influence the growth of prokaryotes, particularly mycobacteria. METHODS The effect of four fat-soluble vitamins was studied in radiometric Bactec® culture. The vitamins were A (including ...

CONTEXT Vitamins B1 (thiamine), B3 (niacin), B6 (pyridoxine), and C (ascorbic acid) are vital for energy, carbohydrate, lipid, and amino acid metabolism and in the regulation of the cellular redox state. Some studies have associated low levels of water-soluble vitamins with metabolic syndrome and its various components. AIMS This study aims to determine the plasma concentrations of vitamins B...
