background and aim: in skeletal muscle, carnitine plays an essential role in the translocation of long-chain fatty-acids into the mitochondrial matrix for subsequent beta-oxidation. despite an abundance of literature describing the basic mechanisms of action of l-carnitine metabolism, there remains some uncertainty regarding the effects of oral l-carnitine supplementation on metabolism and exer...

Creatine, a natural nutrient found in animal foods, is alleged to be an effective nutritional ergogenic aid to enhance sport or exercise performance. Research suggests that oral creatine monohydrate supplementation may increase total muscle creatine [TCr], including both free creatine [FCr] and phosphocreatine [PCr]. Some, but not all, studies suggest that creatine supplementation may enhance p...

-A feeding trial was conducted in eight cows to compare the effect of supplementing commercial yeast species Saccharomyces cerevisiae and Saccharomyces siccum on milk yield and its composition. Cows were randomly assigned to one of the two treatment groups consisting four animals each. Commecial yeast granules were added at the rate of 25 g /cow / day to the concentrate feed in the afternoon fo...

Dietary supplementation is a common practice in athletes with a desire to enhance performance, training, exercise recovery, and health. Supplementation habits of elite athletes in western Canada have been documented, but research is lacking on supplement use by athletes across Canada. The purpose of this descriptive study was to evaluate the dietary supplementation practices and perspectives of...

To establish guidelines for the selenium supplementation in radiotherapy we assessed the benefits and risks of selenium supplementation in radiotherapy. Clinical studies on the use of selenium in radiotherapy were searched in the PubMed electronic database in January 2013. Sixteen clinical studies were identified among the 167 articles selected in the initial search. Ten articles were observati...

As dietary supplementation with β-glucans can stimulate the innate immune response in the porcine gastrointestinal system (GIT), the aim of this study was to determine if the effects of β-glucan supplementation extend beyond the GIT to systemic levels. Hence, the effects of dietary supplementation of β-glucans derived from Laminara digitata, Laminara hyperborea, and Sacharomyces cerevisiae on c...

Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...
