About This Product
Ruby Grapefruit Flavor - 15 sticks per pouch
Sweat Prep + Recovery Mix
Crisp citrus. A little tart. Seriously refreshing.
Ruby Grapefruit was made for the moment when the heat ends and replenishment begins. Bright and refreshing without being overly sweet, it pairs Sauna Stick's mineral-first formula with a sophisticated grapefruit profile you'll actually look forward to drinking.
Each stick provides 80mg calcium, 80mg magnesium, 150mg potassium and 350mg sodium to help replenish the minerals and electrolytes lost through sweat.
Made with naturally sourced electrolytes and ocean-sourced minerals, including powdered coconut water, calcium from seaweed and magnesium from seawater.
Mix with 16-20 oz of cold water before you step into the heat or after you step out. Because heat is only the first half of the ritual.
Sweat. Replenish. Repeat.
