SiS says that the electrolytes (sodium, calcium, magnesium, potassium and zinc) replace those lost from your body via sweat and encourage you to drink the right amount, which in turn helps performance. And most sports science studies agree that dehydration can have a negative impact on performance (basically, you get tired sooner), and that drinking the correct amount of water helps avoid this. Go Hydro + Caffeine is a product from Science in Sport (SiS) designed to help you stay hydrated when exercising, with the additional ingredient of caffeine which provides a small but noticeable increase in mental and physical performance. In simple terms, nootropics are substances that can enhance cognitive performance giving you that mental lift you might need, especially at the latter phases of exercise. So, as well as 40 grams carbohydrate at the 1:0.8 ratio of maltodextrin to fructose, the SiS Beta Fuel Gel with Nootropics contains 1 gram of the amino acid L-taurine, 250 milligrams of Cognizin® to enhance information processing and 200 milligrams of caffeine with 200 milligrams of L-theanine, the amino acid which has been shown to increase subjective feelings of alertness, while reducing feelings of ‘jitters’ that you get with caffeine alone. These are perfect for the athlete who needs to stay hydrated or just about anybody who may find themselves needing some assisted hydration on a hot, humid day.

Hydration supplements are ideal pre workout or throughout your workout. It is also very important to hydrate yourself after a workout.O’Brien, W. J., Stannard, S. R., Clarke, J. A., & Rowlands, D. S. (2013). Fructose–maltodextrin ratio governs exogenous and other CHO oxidation and performance. Medicine & Science in Sports & Exercise, 45(9), 1814-1824. It’s vital for any athlete to drink additional fluids containing electrolytes either before, during, or post-workout. It’s important to refuel as fluid loss impacts exercise and performance. The Hydra 10 has a unique formulation of glucose polymer to help ensure optimised hydration.

The electrolytes help to hydrate the body, regulate nerve and muscle function, and rebuild damaged tissue. Phizz contains 5 electrolytes which include chloride, bicarbonate, magnesium, calcium, potassium and sodium. Phizz also contains 8 B vitamins which includes Niacin (B3) and Riboflavin (B2) which can also help reduce tiredness and fatigue while promoting brain function. Although marketed for people who exercise, Lucozade Fitwater definitely is a good choice as the Dioralyte alternative. On top of that Lucozade Fitwater does not have any taste as all other alternatives reviewed in this post. The electrolyte stamina is ideal for sports performance, people working in high temperatures or just about anybody that expects to lose fluid.
