Background Energy drinks (ED) are widely consumed worldwide, and are recognised for their adverse health effects, usually due to their high caffeine content. However little is known about their impact on oral health and obesity. Thus the aim of this investigation was to review the top 5 selling ED in the UK, (Lucozade, Redbull, Monster, Rockstar and Relentless), for their possible effect on oral health and contribution to obesity. Method The pH and sugar content of the 5 ED were measured and their ingredients reviewed. Their sugar content, pH and ingredients were then linked to oral health and obesity with the aid of existing literature, using the databases Google Scholar, Met Search and PubMed. Results The results showed that all of the 5 ED had pH values below the critical value (5.5), the lowest of which was 2.72 (Lucozade), and thus were all capable of causing dental erosion. From lowest pH value to highest, the ED ranked as follows; Lucozade < Rockstar < Relentless < Redbull < Monster .The ED were also found to contain large amounts of free sugars, Redbull being the only drink to contain less than the daily recommended amount of less than 5% of total energy intake per serving. From lowest to highest sugar content per serving the ED drinks ranked as follows; Redbull < Relentless < Monster < Lucozade < Rockstar. The content of free sugars was found to be capable of contributing to dental caries and the development of obesity. The results also showed that other ingredients contained within the ED, such as caffeine and various acids (malic, citric, lactic and ascorbic) have been found to impact oral health. Conclusion Energy drinks could contribute to dental erosion and the development of obesity in consumers, and thus should be consumed with care, particularly in relation to frequency, quantity and duration. Lucozade and Rockstar were found to potentially have the greatest impact on oral health and obesity.
