![]() One may wonder what is the energizer in these drinks: taurine, caffeine, or sugar or all of them together? The high consumption of taurine-containing energy drinks also renewed the interest in the possible side effects and toxicity of taurine. The presence of taurine at high concentrations in energy drinks and its use by young people and athletes have renewed the need for better understanding of the beneficial and nonbeneficial effects of taurine as well as its mechanisms of action. However, the daily need for the body is close to 3000 mg ( Shao and Hathcock 2008), hence the need to recommend an exogenous taurine supplement. Although meat is very rich in taurine, its consumption in humans only supplies near 400 mg/day of the amino acid. This indicates its important role in human development and the dependence of humans on exogenous taurine intake. The plasma concentration of taurine is known to decrease during human development and aging ( Fukuda et al. In humans, taurine can be found at high concentrations in the plasma (near 50–150 μmol/L) ( Yamamoto 1996 Trautwein and Hayes 1990), bile, and saliva as well as being very abundant in heart tissue (6 μmol/L). Two organs, the heart and the brain, are known to produce their own taurine, but in very limited quantities ( Schaffer and Kim 2018). Taurine is a nonessential amino acid that has received much attention ( Azuma et al. Dans cet article de synthèse, nous nous pencherons en particulier sur l’état actuel de la modulation du système cardiovasculaire par la taurine, et nous discuterons des avenues futures pour son utilisation en tant que traitement de supplémentation dans une maladie cardiovasculaire spécifique : l’hypertrophie et l’insuffisance cardiaque. La plupart de ses effets ont été attribués à sa modulation de l’homéostasie du Ca 2+, ainsi qu’à ses propriétés antioxydantes. Un très grand ensemble de publications a rapporté les bienfaits de la taurine dans le dysfonctionnement hépatique, les lésions gastro-intestinales, l’insuffisance rénale, le diabète et les maladies cardiovasculaires. Aujourd’hui, la taurine est présente dans presque toutes les boissons énergétiques. C’est la raison pour laquelle il est nécessaire de fournir une supplémentation pour cet acide aminé. Deux organes, le cœur et le cerveau, sont connus pour produire leur propre taurine, mais en quantités très limitées. For that reason it is not currently provided as part of the Rev3 products.Īs always, USANA scientists will continue to monitor the best available research on this subject.La taurine est un acide aminé non essentiel qui a reçu beaucoup d’attention. Presently, despite being included in many energy drinks, taurine has not been proven to be energy-giving or beneficial in generally healthy non-deficient adults. Taurine levels in the body also remain relatively constant so typical oral dosages have little effect on overall body levels. However, these findings have not been duplicated conclusively in humans. In recent years taurine has become a common ingredient in energy drinks, partly due to findings in mice that it alleviates muscle fatigue during strenuous workouts. Taurine has traditionally been classified as a non-essential amino acid, but by strict chemical definition it is actually an amino sulfonic acid. As a derivative of another amino acid (cysteine), taurine is synthesized by humans in both the brain and the liver. However, its most important role in humans is its role in digestion, since taurine is a major component of bile acid.
