Promoted as the ultimate hydration drink, coconut water has five key electrolytes: sodium, magnesium, calcium, potassium, and phosphorus. These elements work together to support your body with what it needs to stay hydrated, especially on a warm day. ZICO’s products, which are gluten-free, lactose-free, and dairy-free, contain as much potassium as a banana. Zico Natural is 100 percent pure water from hand-harvested Thai coconuts. Fruit, chocolate, and latte-flavored varieties are also available.
