Functional drinks help replace the electrolytes, vitamins, and minerals lost throughout the day — whether through exercise, travel, sun exposure, or simply being too busy to drink up. The best formulas work with your body, using simple ingredients like salt and coconut water, to help restore balance and boost performance without the sugar crash that often comes with popular sports drinks. And when you're dehydrated, even minimally so, it can impact everything from mood and energy to digestion, skin health, and sleep quality.[2] Dr. Kim Celmer, ND and Grove Wellness Advisor, elaborates: “Low level dehydration can cause headaches, fatigue, brain fog, lower immunity, increased hunger and food cravings, dry skin and chapped lips. Adding an electrolyte formula can help you stay hydrated.”
