The Glowberry flavour of Prime is extremely rare and has proven hard to come by in the UK for many shoppers.

The new Prime flavour tastes of sour apple berries and comes in a glow-in-the-dark bottle.

Prime Hydration - which was created by British rapper KSI and American influencer Logan Paul - is 10% coconut water, contains electrolytes, B vitamins and BCAAs, while also having zero sugar and only around 20 calories per bottle.

When will the ultra rare Glowberry Prime be available in UK Aldi stores?

The supermarket giant said previous Prime launches in stores have been met with "high shopper demand" and this is set to be no different. 

Aldi added: "Shoppers best move quickly - as with all Specialbuys, once they’re gone, they’re gone."
