Hydralite is a tablet which dissolves in water. This is meant to be used before exercise. This tablet is a water balancer and it tastes like a diluted orange. Here it helps keep the fuilds up.
The citrus flavour is really subtle. The tablet fizzes when it is put in water.
You can buy them in a box of 10-14 sachets or as a tube from your local pharmacy. But this one we got it for free in one of the goody bags. The tube is easy to put in your handbag or backpack or gym bag for on the go.
