Go Hydro Tablets with Vitamin C & Iron
Orange
Why We Love It
SiS Orange Hydro Tablets are formulated to support and maintain immune function during and after exercise. They help replace critical electrolytes lost through sweat. Convenient and easy to use, these effervescent tablets dissolve quickly in water, providing a refreshing orange-flavoured hydration solution, without the added calories.
Talk Nerdy To Me
Each effervescent tablet delivers a precise dose of 200mg Vitamin C and 2.5mg Iron, nutrients known to support normal immune function during and after intense physical activity. Additionally, the Hydro tablets contain sodium and potassium, essential electrolyte powder that help maintain fluid balance and prevent dehydration. Go Hydro is designed to meet your sodium needs at a specific concentration (30mmol/L), ensuring effective hydration compared to water alone.
