Gatorade’s promise of rehydration and nutrients all delivered in a deliciously flavored drink might seem too good to be true, and according to some European countries, it is.

In 2012, Gatorade was banned in many European countries for containing brominated vegetable oil and Yellow 5 and 6, which can cause some serious health issues.

The EU banned brominated vegetable oil for its links to nervous system complications, skin irritations, headaches, loss of muscle coordination, memory limitations, and fatigue.

Yellow 5 and 6 are banned in the EU in all children’s food, and these ingredients must be disclosed on labels, as they can cause allergic reactions and contain a carcinogen.

Since brominated vegetable oil is banned full stop in the EU, Gatorade removed the ingredient, and the product was allowed back into the mainstream European market by 2013.

While Gatorade is allowed in most European countries, the drink remains banned in Norway and Austria because it still contains Yellow 5 and 6.
