Background: Red bull has been known as a healthy drink within many populations. The chemical composition of energy drinks can produce multiple adverse effects, including serious behavioral effects. Objective: To study the effect of energy drinks (Red Bull) on brain, liver, kidney, and heart in rabbits. Methods: thirty males albino rabbits were used, animals divided into 3 groups (A, B, and C), each group contain 10 rabbits. Group A treated with high dose of red bull (10 cc), Group B treated with low dose (5 cc), and Group C is control group. Results: The results showed that control group had no any pathological changes while both Groups A and B showed many pathological changes, Group A showed renal vascular congestion, hemorrhage of interstitial tissue, focal atrophy, and degeneration of lining epithelium of proximal and distal convoluted tubules, while Group B showed renal vascular congestion, glomerular capillary congestion, hemorrhage of interstitial tissue with swelling of lining epithelium of proximal and distal convoluted tubules that appeared as pale cytoplasm with star-shaped lumen, and swelling of glomeruli; this reveals that there is dose–response relationship between treated groups with low and high dose of red bull. Conclusion: Energy drinks have dose–response relationship with adverse effect; it has become apparent that the consumption of these energy drinks will seriously harm the body.
