Abstract:

The term “vitamin” or “vitamine” was first used in 1912. What later became known as vitamin deficiency diseases — scurvy, beriberi, night blindness and xeropthalmia — had plagued the world from antiquity. From 1900 through the 1930s, experiments with animals helped to advance knowledge of vitamins considerably. There are 15 vitamins of significance for livestock. A number of factors influence vitamin requirements and vitamin utilization, including physiological make-up and production function; confinement rearing without pasture; stress, disease and adverse environmental conditions; vitamin an

Abstract:

Vitamins have many established roles in human health. However, the role of habitual dietary intake of vitamins in glucose homeostasis in individuals after acute pancreatitis (AP) is yet to be elucidated. The aim was to investigate the associations between habitual intake of fat- and water-soluble vitamins/vitamers and markers of glucose metabolism (fasting plasma glucose (FPG), homeostasis model assessment insulin resistance (HOMA-IR) index, and homeostasis model assessment β-cell function (HOMA-β)) in individuals after AP.

Abstract:

Fat-soluble vitamins such as A, D, E, and K have an essential role in maintaining health. Deficiencies of vitamins A, D, E, and K are commonly known to cause night blindness, osteomalacia, increased oxidative cell stress, and hemorrhage. Vitamins are chemically reactive compounds that are fragile due to their sensitive and unstable nature. Aside from being prone to degradation due to environmental factors, the vitamins encounter various digestion factors that potentially affect their bioaccessibility and bioavailability when ingested. During digestion, the low pH environment of gastric juice m

Abstract:

The discovery of the vitamins was a major scientific achievement in our understanding of health and disease. In 1912, Casimir Funk originally coined the term vitamine. The major period of discovery began in the early nineteenth century and ended at the mid-twentieth century. The puzzle of each vitamin was solved through the work and contributions of epidemiologists, physicians, physiologists, and chemists. Rather than a mythical story of crowning scientific breakthroughs, the reality was a slow, stepwise progress that included setbacks, contradictions, refutations, and some chicanery. Resear

Abstract:

Vitamins are essential for a healthy life. Compared to other nutrients, the body needs them in very small amounts. B vitamins, often known as the vitamin B complex, are a class of water-soluble vitamins with key functions in cellular metabolism. Thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin (vitamin B7), folate (vitamin B9), often known as folic acid, and cobalamin (vitamin B12) are the eight distinct vitamins that collectively constitute the vitamin B complex.

Abstract:

In this study, we aimed to evaluate the effect of vitamins A, C, and E against aflatoxin B1 (AFB1) on blood cultures in relation to induction of sister chromatid exchange (SCE). The results indicated genotoxic and mutagenic damage in cultured human lymphocytes exposed to AFB1. The results showed that 5 μM concentration of AFB1 increased SCE. When vitamins A, C, and E were added to AFB1, the frequency of SCE decreased. These results suggest that vitamins A, C, and E could effectively inhibit AFB1-induced SCE, which may partially responsible for its mutagenic effect of AFB1. Besides, the protect

The aim of the present study was to test the hypothesis that maternal intake of antioxidant vitamins is associated with maternal and cord plasma levels at delivery. Women were recruited in early pregnancy in Aberdeen Maternity Hospital and habitual diet during pregnancy was assessed by a food-frequency questionnaire mailed at 34 weeks gestation. Blood samples were taken at recruitment (n1149) and maternal (n1149) and cord blood samples (n747) taken at delivery for analyses of vitamins A, C, E and β-carotene. Maternal plasma levels of vitamin E and β-carotene at delivery were significantly high

Vitamins C and E are antioxidants that indirectly have a role as an antiviral. Vitamin D can increase immunity, so its availability is important during the COVID-19 pandemic.

Abstract:

Atherosclerosis, the great killer of Western society, probably is initiated when the balance of subendothelial lipoproteins and oxidation potential is upset. Oxidation products, especially oxidized low‐density lipoprotein, set into motion the cascading of numerous pathways, culminating in the fibrous atherosclerotic plaque. The natural antioxidant system includes enzymes and vitamins A, E, and C. The lipophilic vitamins A and E protect the fatty acid components of lipoproteins and membranes, and vitamin C functions in the aqueous phase both directly and by regenerating oxidized vitamin E.
