New research has revealed that a cup of coffee will give you a buzz and is likely to be more effective than body and mind-enhancing drinks with ingredients like guarana and ginseng.

Scientist found there was an overwhelming lack of evidence to suggest that ingredients like guarana enhance physical or cognitive performance and that it was in fact a generous dose of caffeine which gives people that buzz.

The study, published in the Nutrition Reviews journal, went through various articles which examined the effects of energy ingredients and / or in combination with caffeine and there was little information to support the claims.
