SIDE EFFECTS OF TAURINE SUPPLEMENTATION FREE

Twenty-four members of the study consumed two sugar-free energy drinks containing 100 mg of caffeine and 2000 mg of taurine, or a controlled drink consisting of juice, free of any caffeine or taurine. When supplemented with caffeine combined with taurine, people with this condition have irregular heartbeat (arrhythmia). A randomized, double-blind, crossover study published in the International Journal of Cardiology in March 2017 reported 24 people who had inherited genetic long QT syndrome (LQTS). The taurine in energy drinks may also be of concern in people with genetic heart conditions.

Other studies have also shown that taurine can have adverse effects when combined with caffeine! (Pharmacotherapy, February 2012 46(2):192-9, Amino Acids 2001 20(1):75-82, Int J Cardiovasc Imaging 2015 Mar 31(3):595-601). 400 mg of caffeine, which is equivalent to about 4 cups of coffee, is generally regarded as safe by the U.S. There was also a greater increase in blood pressure in caffeine with taurine combination compared to caffeine alone. This randomized, double‐blind, controlled, crossover study tested 18 young, healthy volunteers. Also, in the study an irregular heart rhythm resulted two hours after consuming an energy drink containing caffeine and taurine, compared to a caffeine-only drink. A study published on Apin the Journal of the American Heart Association found that energy drinks containing taurine and caffeine had a negative effect on the heart compared to caffeine-only beverages. Research has shown that the amino acid taurine can have adverse effects on the cardiovascular system when combined with caffeine. “Higgins and colleagues believe that the negative effect may be related to the combination of ingredients in the energy drink, such as caffeine, taurine, sugar and other herbals on the endothelium (lining of the blood vessels).” They found vessel dilation was on average 5.1 percent in diameter before the energy drink and fell to 2.8 percent diameter after, suggesting acute impairment in vascular function. “One and a half hours after consuming the energy drink, researchers checked the young adults’ artery flow-mediated dilation – an ultrasound measurement that indicates overall blood vessel health. Researchers repeated endothelial function testing 90 minutes later. The article further stated, “John Higgins, M.D., M.B.A., of McGovern Medical School at UTHealth in Houston and colleagues, studied 44 non-smoking, healthy medical students in their 20s by testing their endothelial function before each of the students drank a 24-ounce energy drink. CST (Central Standard Time) on Monday, November 12, 2018. The placebo drink contained carbonated water, lime juice and cherry flavoring.Īt the 2018 Annual American Heart Association’s meeting and Scientific Sessions, it was reported that “young, healthy adults experienced notably diminished blood vessel function soon after consuming one energy drink,” according to preliminary research from a small study that was presented in Chicago at the American Heart Association’s Scientific Sessions 2018. Other common ingredients in the energy drinks in the study included taurine (an amino acid), glucuronolactone (found in plants and connective tissues) and B vitamins. Caffeine at doses under 400 milligrams is not expected to induce any electrocardiographic changes. The study included only healthy individuals between the ages of 18 to 40, and the results may be different in other populations.īoth energy beverages tested contained 304 to 320 milligrams of caffeine per 32 fluid ounces. The study is the largest controlled study of the effects of energy drinks on the heart and blood pressure in young healthy volunteers. Long School of Pharmacy and Health Sciences in Stockton, California. Shah, PharmD, professor of pharmacy practice at University of the Pacific, Thomas J. We urgently need to investigate the particular ingredient or combination of ingredients in different types of energy drinks that might explain the findings seen in our clinical trial,” said lead author Sachin A. “We found an association between consuming energy drinks and changes in QT intervals and blood pressure that cannot be attributed to caffeine. ScienceDaily recently reported on this study on May 29 th, 2019. It was reported in the Journal of the American Heart Association on June 4 th, 2019 that several hours after drinking 32 ounces of energy drinks, the heart’s electrical activity was abnormal compared to a placebo drink.
