Concentrated liquid supplements are easy to take and store in your pocket while riding. They offer the same advantages of gel supplements without the drawback of dirtying your hands or - even worse - accidentally dispersing the content. Liquid supplements mainly consist of Magnesium, Iron and Carnitine : these nutrients are essential for the proper functioning of your organism when it undergoes sustained efforts and are useful to reduce recovery time after workout. The lack of one or more of them leads to a significant performance decrease, either while competing or training.
