Red Bull is the best treatment for psychosis in teenagers, a study claims.

The energy drink touts itself as the best boost you can get - with the tag line 'Red Bull gives you wings'.

But new research presented at this year's International Early Psychosis Association meeting shows that the beverage contains a crucial additive to ease depressive episodes.

Taurine, an additive in Red Bull, also naturally occurs in the human body - and research shows it could help ease symptoms in early stage psychosis patients

Taurine, an amino acid, is used in a number of foods and drinks.

It can also be found in the human body, helping the cardiovascular system to function and protecting the nervous system.

However, studies show people suffering from psychosis may be lacking in taurine levels, and during a psychotic episode sufferers' heart rate can rocket.

And so, an international coalition of scientists investigated how drinking Red Bull could alleviate the effects of a psychotic episode.

The scientists gathered a group of 121 patients aged between 18 and 25 years old with early stage psychosis in Melbourne, Australia.

All of the patients were taking low dose antipsychotic medication, and attending early intervention services.

They each received four grams of taurine or a placebo dose once daily.

Researchers then used a scoring system to assess their symptoms, and a different tool to assess cognition.

A total of 86 patients (47 receiving taurine and 39 placebo) were included in the final analysis.

Taurine was found to be both safe and well tolerated.

Taurine significantly improved symptoms, both in their overall score and the part specifically analyzing psychosis.

There were also improvements in depression symptoms and general overall functioning - including social and workplace functioning.

However, there was no difference between groups regarding cognition.

The authors conclude: 'Although taurine supplementation did not improve cognition, it appears to improve core symptoms and depression in patients with FEP.

'The use of taurine warrants further investigation in larger randomised studies, particularly early in the course of psychosis.'
