These increases in heart rate and blood pressure are thought to be largely due Red Bull’s caffeine content, as one large 12-ounce (355-ml) can contains 108 mg of caffeine - about the same amount as a cup of coffee ( 2, 10, 11).ĭespite these increases, moderate and occasional intake of Red Bull is unlikely to cause serious heart problems in healthy adults. Several studies in healthy adults have shown that drinking one 12-ounce (355-ml) can of Red Bull significantly increased blood pressure and heart rate levels within 90 minutes and up to 24 hours after consumption ( 6, 7, 8, 9). Can increase blood pressure and heart rateīlood pressure and heart rate are two important measures for heart health, as increased levels have been associated with a higher risk of hypertension (high blood pressure) and heart disease ( 4, 5).
Though Red Bull remains a popular beverage, research suggests that it may negatively affect your health.
Possible side effects of drinking Red Bull Due to its combination of ingredients, there are concerns over its potential side effects, especially when consumed in larger amounts. Red Bull is a sugar-sweetened, caffeinated drink marketed as a way to boost mental and physical performance. While the ingredients in Red Bull may provide a boost of energy, they may also cause short- and long-term side effects - especially in larger quantities. It’s also high in several B vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), B6, and B12 ( 2).Īdditionally, Red Bull has sugar-free options, including Red Bull Zero and Red Bull Sugarfree, which are made with the artificial sweeteners aspartame and acesulfame K instead of sugar ( 3).
While the exact composition varies by country, additional ingredients in Red Bull include sugar, carbonated water, baking soda, citric acid, magnesium carbonate, glucuronolactone, and artificial colors and flavors ( 1). The authors are planning further studies to examine the potential benefits of taurine both alone and in conjunction with other supplements in the treatment of psychosis.First sold in 1987 in Austria, Red Bull is a carbonated beverage containing caffeine, as well as other energy-boosting compounds, including several B vitamins and taurine ( 1). The use of taurine warrants further investigation in larger randomised studies, particularly early in the course of psychosis." The authors conclude: "Although taurine supplementation did not improve cognition, it appears to improve core symptoms and depression in patients with FEP. However, there was no difference between groups regarding cognition. There were also improvements in depression symptoms (rated by the Calgary Depression Scale for Schizophrenia ) and general overall functioning (including social and workplace functioning). Taurine significantly improved symptoms on the BPRS scale, both in overall score and the part specifically analysing psychosis. Taurine was found to be both safe and well tolerated. A scoring system called BPRS (Brief Psychiatric Rating Scale) was used to assess symptoms, and a different tool called MCCB (MATRICS consensus cognitive battery) was used to assess cognition.Ī total of 86 patients (47 receiving taurine and 39 placebo) were included in the final analysis. Patients received taurine 4 grams or placebo once daily. In this new study, the authors analysed the efficacy of taurine supplementation in improving both symptoms and cognition in patients with FEP.Ī total of 121 patients (aged 18-25 years) with FEP, taking low dose antipsychotic medication, and attending Orygen's early intervention services in Melbourne agreed to take part in the study. For all these reasons, it was chosen as an interesting substance to study for potential treatment of psychosis. It is also involved in development of the nervous system.
It exhibits an inhibitory neuro-modulatory effect in the nervous system and also functions as a neuroprotective agent. Taurine is an amino acid naturally occurring in the body that has various functions, including aiding the function of the cardiovascular system. The study is by Dr Colin O'Donnell, Donegal Mental Health Service, Letterkenny, County Donegal, Ireland, and Professor Patrick McGorry and Dr Kelly Allott, Orygen, The National Centre of Excellence in Youth Mental Health, Parkville, VIC, Australia, and colleagues. New research presented at this year's International Early Psychosis Association (IEPA) meeting in Milan, Italy (20-22 October) shows that supplementation with taurine (well known as an additive found in drinks such as Red Bull) improves symptoms in young people suffering a first episode of psychosis (FEP).
