If you need more than a bottle of water to keep you going at the gym, then a sports drink is definitely the answer. A good sports drink puts back in what sweating and exercising takes out, but so many out there are full of sugar, sweetener and additives, not so healthy after a great workout. Unlike other drinks, a new range from Taut isn't packed with calories, aspartame and nasty colourings. Taut is an isotonic drink full of vitamin B6 (good for energy) and minerals and only contains 119 calories so you won't have to worry about doing an extra ten minutes on the cross-trainer to burn it off. We love the Goji & Pomegranate flavour which is good enough to drink whether you're at the gym or not!
