Sean Evans arrived at his local branch of Aldi at 7am. The supermarket had tweeted that it would be selling 300 bottles of Prime Hydration that day. A queue had already formed outside. Within twenty minutes, the bottles had sold out.

"There were older people pushing kids out of the way," says Evans. "Mental!"

Prime was launched last year by the boxer Logan Paul and the rapper KSI. Both have huge followings on social media - more than there are people in VietnamA Southeast Asian country with a population of nearly 100 million. .

When the first Prime drinks went on sale in the US, they sold out within hours. When Prime Hydration arrived in the UK, it caused a similar buzz.

Prime Hydration is mainly water and coconut water. Dr Linia Patel, a sports nutritionist,¹ questions its value: "The majority of us don't need a special drink to hydrate us. Just get a good bottle of water."

But while Prime Hydration is considered safe for children, Prime Energy is not. A 335ml can contains 200mg of caffeineA drug that increases the activity of the brain and nervous system. It is found in many drinks, such as tea, coffee and soft drinks, as well as energy drinks, which have large amounts of caffeine. . Experts say even older children should not have more than 100mg of caffeine a day.

Prime Energy is not supposed to be sold to anyone under 18, but some children are still getting hold of it. A pupil at a primary school in Wales had to have their stomach pumpedA medical procedure to remove everything in your stomach. after drinking Prime Energy.

In 2018, doctors called for a ban on the sale of energy drinks to those under 16. It said that far from providing energy, the drinks often made young people "lethargicA lack of energy or sluggish. , agitated and anxious".

The UK government said it was in favour of a ban - but has not brought one in.

Now some schools are banning Prime. One said that the drinks had become status symbols. Children were "removing themselves from their lessons to be seen drinking with the Prime branded bottles".

Others said that some pupils were selling Prime to classmates for far more than the shop price.

Yes: There is no way Prime would be so successful if it did not have Logan Paul and KSI behind it. People can get all the hydration they need from water and most have plenty of energy.

No: There was already a big market for sports and energy drinks before Prime came along, so there is obviously a big demand for them. All brands use advertising: Prime's is just better than most.   

Or... There is nothing wrong with a bit of hype. People today buy products for the excitement they create and lifestyle they suggest as much as for their intrinsicSomething that is in the basic nature of a thing. value - and Prime is very exciting.
