The GO Hydro Tablets from SiS are the go-to for minimal calorie electrolyte replacement. Sodium, an important electrolyte for stimulating thirst, improving taste, and promoting absorption and retention of fluid, is lost through sweat and requires replenishing. Yet, as active folk and athletes, we often don't get near enough to support our increased mineral needs. SiS electrolyte tabs are for the days when hydration is required without the added calories. At the office, post-work before your workout, pre-race...Go Hydro Tabs are an amazing option for keeping the sugars low and the hydration coming. As an effervescent tablet that readily dissolves in plain water, it’s easy to meet your hydration needs without the calories. These Hydro Tablets are also Informed Sport Certified, so even the most elite athletes can feel good about this product.
