Yes, it isn't loaded with caffeine, but all in all it's so much nicer than Red Bull. The taste is something we all know and love, it's been around for years. It's full of glucose, which as it says on the bottle, is what the body needs most for energy. Yes, Red Bull gives you a buzz from the caffeine content, but once that wears off you end up feeling awful.
It's great for sports, the glucose gives you the energy to really go for it. And of course, more recently they've expanded the lineup, so there's a Lucozade for any situation. Low calories, fizzy, still, multiple flavours, you're guaranteed to find one you'll like.
Not only is it better than Red Bull, it's cheaper too, and you get more for your money. My local shop currently has it at £1.25 for a 500ml bottle, or 2 for £1.50. On the other hand, Red Bull is £1.40 for a 250ml can. And of course you can get a much bigger bottle, around £2 will get you a whole litre, although it can be had for as little as £1 if you know where to look.
And finally, being made by GSK, it's a British product, which in my book makes it cooler than Red Bull.
