The effect of grape seed extract (GSE) feed supplementation on performance, antioxidant enzyme activity, and immune responses in broiler chickens suffering from heat stress were investigated in this study. Experimental diets including control diet (with no additive), 3 levels of GSE (150, 300, 450 mg/kg), and one level of vitamin C (300 mg/kg) as a positive control were fed to the birds from 1 ...

background: nonalcoholic fatty liver disease (nafld) is the most common chronic liver disease in the world. oral administration of symbiotic and vitamin e has been proposed as an effective treatment in nafld patients. this study was carried out to assess the effects of symbiotic and/or vitamin e supplementation on liver enzymes, leptin, lipid profile, and some parameters of insulin resistance (...

OBJECTIVES: To study the effect of supplementation with an association of small physiological amounts of antioxidant nutrients upon biochemical parameters and indicators of oxidative stress and antioxidant enzymes. DESIGN: The study included a double-blind placebo-controlled design. SUBJECTS: 575 elderly long term hospitalized subjects aged 65-103 years. INTERVENTION: Four groups were compared....

Vitamin C is essential for fish diets because many species cannot syntethize it. This vitamin is needed for bone and cartilage formation. Moreover, it acts as antioxidant and improve the immunological system. The present work investigated the effects of vitamin C diet supplementation to spotted sorubim (Pseudoplatystoma coruscans) fingerlings by frequency of bone and cartilage deformation. Asco...

This experiment investigated the effects of dietary supplementation of vitamin E and vitamin C on sow reproductive performance and transfer of vitamin E to piglets via the placenta, colostrum and milk. A total of 58 sows were allocated to the following treatment diets: control, vitamin C 1 g/day, vitamin C 10 g/day, vitamin E 200 mg/kg feed, vitamin E 400 mg/kg fed, and vitamins E and C (vitami...

Exercise induces a multitude of physiological and biochemical changes in blood affecting its redox status. Tissue damage resulting from exercise induces activation of inflammatory cells followed by the increased activity of myeloperoxidase (MPO) in circulation. Vitamin C readily scavenges free radicals and may thereby prevent oxidative damage of important biological macromolecules. The aim of t...

BACKGROUND Both vitamin C deficiency and inflammation are prevalent in maintenance hemodialysis (MHD) patients. In this study, we aimed to elucidate the effect of oral vitamin C supplementation on inflammatory status in MHD patients with low vitamin C level and high hypersensitive C-reactive protein (hs-CRP) level. METHODS A total of 128 patients were recruited in our present study. Patients ...

The SUpplementation en VItamines et Mineraux AntioXydants (SU.VI.MAX) study, a randomised double-blind, primary-prevention trial showed that after 7.5 years, low-dose antioxidant supplementation lowered the total cancer incidence in men, but not in women. To explain this difference in the impact of antioxidant supplementation in men and women, we hypothesised that the effect of supplementation ...

Problem statement: Patients with active pulmonary Tuberculosis (TB) are malnourished as indicated by reductions in lean mass, anthropometric indices and micronutrient status. Supplementation with vitamins may prove to be beneficial. Limited information is available on the supplementation of vitamin C and E in pulmonary TB patients. Hence, the present study was undertaken to address the question...

Placebo-controlled trials have shown that vitamin C supplementation decreases the duration and severity of common cold infections. However, the magnitude of the benefit has substantially varied, hampering conclusions about the clinical significance of the vitamin. In this paper, 23 studies with regular vitamin C supplementation (> or = 1 g/day) were analyzed to find out factors that may explain...
