Dr Lee also notes that there is added zinc, and said: "Most children do not need zinc supplements – it is readily obtained from the diet. This can cause symptoms too, such as vomiting, diarrhoea and headaches."

Although it's not easy to find all the ingredients online, Dr Lee also notes that there are other things to consider when deciding whether to buy your children a Prime drink. She said: "Dipotassium phosphate is an artificial flavour enhancer and preservative which is said to be safe for consumption but can cause symptoms such as nausea, vomiting, headaches and constipation."

Arsenal’s Chief Commercial Officer, Juliet Slot, added: “We are always looking to join forces with new, exciting and forward-thinking brands. PRIME falls comfortably into that category, with a product and founders at the forefront of modern culture. A doctor has now issued a warning to parents about the drink's high caffeine content. Prime energy contains a whopping 200mg of caffeine, compared to 86.4mg in a can of Monster Energy. Prime Hydration KSI Flavour is a limited edition energy drink that combines the refreshing taste of grapefruit and lime with the power of caffeine and electrolytes.Prime is marketed as zero sugar and low calorie, but it's got sucralose, which is an "artificial sweetener which has been shown to alter the gut microbiome and increase levels of systemic inflammation". Whether you need a boost for your gaming, sports, or everyday activities, Prime Hydration KSI Flavour can help you stay hydrated and energized. Plus, you can enjoy the unique flavour created by the YouTube star and boxing champion KSI, who is a fan of Prime Hydration. The doctor added that Prime is made from coconut water, which is "full of electrolytes (sodium and potassium)" but "again, children obtain plenty of these from their diet. They do not need any extra from an energy drink. What they need during the day is plenty of good old-fashioned, water."

The energy version of Prime isn't officially sold in major supermarkets in the UK yet, but some corner shops have been selling it. However, from this month they are set to be more widely available in the UK, reports The Mirror. PRIME co-founder and lifelong supporter, KSI, said: “Honestly, I can’t believe it, this is a childhood dream of mine. KSI is a lifelong Arsenal supporter and it’s fantastic we can keep this in the family. I’m sure our supporters will love the drink and I’m excited to see the fun ways we will bring this partnership to life.The flavours of Prime Hydration drinks in Aldi stores include Meta Moon, Lemon and Lime, Ice Pop, Blue Raspberry and a 'KSI' flavour. But while shoppers are rushing to buy the Hydration version of the highly-desired drink, a doctor has warned parents to avoid the lesser-available Energy version of Prime.
