Low-calorie high electrolyte effervescent tablet with added caffeine used to hydrate & provide a mental & physical boost during training or racing: • Simply drop in water to provide a high electrolyte drink• High in sodium to help promote hydration• 75 mg caffeine per tablet• Store in a cool dry place• Suitable for Vegans About Si S GO Hydro + Caffeine Si S GO Hydro + Caffeine builds upon the scientifically based formulation of Si S GO Hydro by ensuring you are effectively hydrated for performance whilst also providing 75 mg of caffeine per tablet. As an effervescent tablet that readily dissolves in plain water, it represents a highly practical approach (simply drop one tablet in your 500 ml water bottle) to ensure that all of your electrolyte, fluid & caffeine requirements are met in its most simple format. The addition of caffeine has been repeatedly shown by sport scientists to improve performance by providing both a physical & mental boost just when we need it. Si S GO Hydro is a practical strategy to ensure hydration without the calories. Why should I take Si S GO Hydro + Caffeine? During moderate to intense exercise, we may produce 1-2 litres (L) of sweat (containing fluid & important electrolytes) per hour depending on the environmental conditions. If such fluid losses are not replaced at an appropriate rate, dehydration occurs & performance can be impaired. In a dehydrated state, our body temperature rises, our heart rate increases, we deplete carbohydrate stores quicker & we perceive the exercise to be more intense. In essence, we have to work so much harder just to perform at the same speed or power output & thus, dehydration is considered a major cause of fatigue. Si S GO Hydro therefore meets your sodium requirements in an appropriate amount (0.7 grams per L) & concentration (30 mmol/L) that is scientifically proven to produce superior hydration compared with plain water. Caffeine has been added to Si S GO Hydro because of the many physiological benefits during exercise that can collectively improve performance. Caffeine can increase fat utilisation therefore effectively sparing the use of our limited carbohydrate stores for later use during exercise. Caffeine can also have direct effects on the brain by improving reaction times & lowering our perception of effort for a given workload, thus making the exercise now seem easier. Caffeine is undoubtedly one of the most research proven methods to improve your performance.
