"Its inclusion in these supplements is a little puzzling because our research would suggest that instead of being a pick-me-up, the taurine actually would have more of a sedative effect on the brain," the scientists said. The thalamus is involved in sleep/wake cycle pathways in the brain and other activities. They found taurine working deep inside the brain, in the "regulatory" area of the thalamus, interacting with neurotransmitters. Įven though taurine is known to be a key amino acid, the researchers say they're curious and puzzled still about the function of taurine in the brain, and have more questions than answers. In a recent article from, researchers at Weill Cornell Medical College in New York say they were "surprised" to find taurine "extraordinarily active" on brain receptors. But recently they've discovered a more defined area of taurine's neurological activity. Scientists have known for a couple of years that taurine is involved somehow in the development and function of the brain. Is Taurine an Upper or Downer? Surprising New Research on the Brain For these reasons, it's banned in some Scandinavian countries after being linked to the deaths of three consumers. Studies have implicated energy drinks in illnesses ranging from high blood pressure to strokes and seizures to heart disease. Could this lead to a vicious cycle of dependency? Probably not, but research has yet to conclude whether or not this is a serious issue. Some argue that this may cause a person to feel unsatisfied with the lack of adrenalin they receive from the energy drink, causing them to reach for more caffeine. Since it has been shown to mitigate anxiety, it may counteract the effects of caffeine in energy drinks. Taurine, mostly in its natural form, actually shows positive effects on the cardiovascular system, nervous system, and immune system. While this may sound beneficial, perhaps it's not the best thing to intake when seeking energy for your daily tasks. Taurine shows an anxiolytic effect on the central nervous system, causing a possible reduction of anxiety symptoms associated with caffeine intake. Since taurine is created naturally in the human body, a good diet supplies all you need.īecause taurine is utilized by the body during exercise and in times of stress, it's become a popular ingredient in energy drinks. It was first discovered in the bile of bulls and is now produced synthetically by the truckload. Taurine is a free form amino acid contained in foods and manufactured in the body from the amino acid cysteine. One of the main reasons is taurine, a common ingredient found in the caffeine and sugar-laden concoctions. Further studies would be required.The multi-billion dollar phenomenon of energy drinks has captured the attention of scientists and nutritionists across the country. It concluded that the contribution of energy drinks to overall caffeine intake is not a matter of concern for non-pregnant adults – moderation of caffeine intake, from whatever source, is advisable during pregnancy substitution of energy drinks for normal beverages by children could lead to increased caffeine levels in this group – this could result in transient behavioural changes such as arousal, irritability, nervousness or anxiety the interaction of the constituents of energy drinks has not been well studied, nor has the interaction of caffeine and taurine with alcohol particularly under conditions of exercise and consequent dehydration through sweating and the safety in use of taurine and glucuronolactone as delivered in energy drinks has not been established. These were based on an assumed maximum intake level of 0.5 litre of energy drink per day. This committee, which carries out risk assessment on foodstuffs in Europe, reached a number of conclusions in its opinion. In 1999 the European Scientific Committee for Food – SCF – was asked by the European Commission for an opinion on caffeine, taurine and glucuronolactone as constituents of so-called energy drinks. Stimulant drinks contain three active ingredients, caffeine, glucuronolactone and taurine. Appearing before an Oireachtas committee.
