Experimental studies suggest a protective effect of B-vitamins on breast cancer risk, potentially modulated by alcohol intake. However, epidemiological studies are limited, especially regarding non-folate B-vitamins. Furthermore, few studies included quantitative assessment of supplemental intake. This prospective study aimed to investigate the associations between intakes of B-vitamins (dietary, supplemental, total) and breast cancer risk. 27,853 women aged ≥45 years from the NutriNet-Santé cohort (2009-2016) were included, with a median follow-up time of 4...

The US FDA published new nutrition-labeling regulations in May 2016. For the first time since the implementation of the Nutrition Labeling and Education Act of 1990, the Daily Value (DV) for most vitamins will change, as will the units of measurement used in nutrition labeling for some vitamins. For some food categories, the Reference Amounts Customarily Consumed (RACCs) will increase to reflect portions commonly consumed on a single occasion. These regulatory changes are now effective, and product label changes will be mandatory beginning 26 July 2018...

Lipotoxicity induced by saturated fatty acids (SFAs) plays a pathological role in the development of non-alcoholic fatty liver disease (NAFLD); however, the exact mechanism remains to be clearly elucidated. Palmitate is the most abundant SFA in the circulation and major lipotoxic inducer. Accumulating evidence supports that autophagy induction is protective against palmitate-induced cell death in a variety of cell types, including hepatocytes. Nicotinamide is the amide form of nicotinic acid (vitamin B3, Niacin) and a dietary supplementation as a source of vitamin B3...

Besides being incorporated into proteins, Trp, an indispensable AA, is involved in numerous metabolic pathways. Previous data showed that Trp conversion into kynurenine (Kyn) and nicotinamide (Nam) differs among studies, and such differences cannot be explained by different dietary niacin supplies. We hypothesized that pig genotype influences Trp metabolism and thus the conversion of Trp into its metabolites. The objective of this study was to compare plasma appearance of Trp and related metabolites in 12 Duroc and 12 Piétrain crossbred postweaning pigs fed 2 contrasting dietary Trp levels...

PURPOSE OF REVIEW: This review summarizes the evidence supporting a relationship between lowering triglycerides (TGs) and TG-rich lipoprotein cholesterol (TGRL-C) levels and reduced atherosclerotic cardiovascular disease (ASCVD) event risk. RECENT FINDINGS: Data from observational investigations, including studies of genetic variants, provide evidence consistent with a causal relationship between elevations in TG and TGRL-C and greater risk for ASCVD. Randomized controlled trial evidence of ASCVD risk reduction with therapies that substantially lower TG and TGRL-C is limited by the fact that no large-scale trial results have been published from a study that enrolled subjects selected specifically on the basis of TG or TGRL-C elevation, although three such trials are underway or in the planning stages...

The periparturient period is accompanied by metabolic and oxidative stress. Niacin is known to decrease lipolysis but is also reported to have anti-oxidative effects. Therefore, we examined the effects of energy supply and a nicotinic acid (NA) supplementation on anti-oxidative serum parameters and on the expression of oxidative stress-related genes in blood leucocytes of periparturient dairy cows, differing in parity. Twenty-nine pluriparous and 18 primiparous cows were allocated to four different feeding groups 42 days before expected parturition until 100 days postpartum and fed a ration with either a low concentrate proportion of 30% (LC) or a high concentrate proportion of 60% (HC)...

PURPOSE: Results of a study to test the hypothesis that taking niacin simultaneously with different forms of aspirin would reduce the occurrence of niacin-induced flushing are reported. METHODS: Traditionally, taking enteral absorbed aspirin 30 minutes before a niacin dose has been shown to reduce flushing by 30-50% relative to nonuse of aspirin. The objective of the study was to evaluate the efficacy of enteral absorbed and orally dissolved aspirin, taken at the same time as niacin, in reducing the frequency of moderate-to-severe flushing...

INTRODUCTION: Chronic pancreatitis by definition is a recurrent episode of acute pancreatitis and is commonly associated with alcoholism in the US. Another cause of chronic pancreatitis is hypertriglyceridemia (HTGP);, occurring in 1-5 percent of cases. The incidence of HTGP is higher in patients with diabetes and HIV, usually requiring triglyceride levels > 1000 mg/dL. CASE: A 33 year old man with uncontrolled type 1 diabetes and recurrent pancreatitis, first diagnosed 5 years prior, presented as a transfer from an outside hospital for a recurrent episode of HTGP...

Niacin, as an antidyslipidemic drug, elicits a strong flushing response by release of prostaglandin (PG) D2 However, whether niacin is beneficial for inflammatory bowel disease (IBD) remains unclear. Here, we observed niacin administration-enhanced PGD2 production in colon tissues in dextran sulfate sodium (DSS)-challenged mice, and protected mice against DSS or 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis in D prostanoid receptor 1 (DP1)-dependent manner. Specific ablation of DP1 receptor in vascular endothelial cells, colonic epithelium, and myeloid cells augmented DSS/TNBS-induced colitis in mice through increasing vascular permeability, promoting apoptosis of epithelial cells, and stimulating pro-inflammatory cytokine secretion of macrophages, respectively...

NAD (Nicotinamide Adenine Dinucleotide) biosynthesis is vital for bacterial physiology and plays an important role in cellular metabolism. A naturally occurring vitamin B complex, niacin (nicotinic acid), is a precursor of coenzymes NAD and NADP. Here, we study the impact of niacin on global gene expression of Streptococcus pneumoniae D39 and elucidate the role of NiaR as a transcriptional regulator of niaX, nadC, and pnuC. Transcriptome comparison of the D39 wild-type grown in chemically defined medium (CDM) with 0 to 10 mM niacin revealed elevated expression of various genes, including niaX, nadC, pnuC, fba, rex, gapN, pncB, gap, adhE, and adhB2 that are putatively involved in the transport and utilization of niacin...

REVIEW
Kimbell R Duncan, Yuichiro J Suzuki
Vitamin E refers to a family of compounds that function as lipid-soluble antioxidants capable of preventing lipid peroxidation. Naturally occurring forms of vitamin E include tocopherols and tocotrienols. Vitamin E in dietary supplements and fortified foods is often an esterified form of α-tocopherol, the most common esters being acetate and succinate. The vitamin E esters are hydrolyzed and converted into free α-tocopherol prior to absorption in the intestinal tract. Because its functions are relevant to many chronic diseases, vitamin E has been extensively studied in respect to a variety of diseases as well as cosmetic applications...
