12 Science-Backed Ways to Make the Ultimate Immune-Boosting Holiday Cocktail (Yes, Really!)

9. Coconut Water and Electrolyte Bases: Hydration-first mixers

Electrolytes—sodium, potassium, magnesium—support cellular hydration and can be useful in contexts of fluid loss. Coconut water is a natural, subtly sweet mixer that supplies potassium and a pleasant mouthfeel. Research sources like Everyday Health and Good Housekeeping highlight electrolyte products and note that balanced blends support hydration when needed. To use coconut water in cocktails, mix it with a lower-proof spirit, fresh citrus, and a spritz of soda for a hydrating-feeling option. Another approach is to add a measured electrolyte tablet to a noncarbonated mixer before combining with spirits, which can help maintain hydration balance across a night of sipping. Avoid assuming these mixers eliminate alcohol’s dehydrating effects—pair them with water and moderate alcohol intake to preserve any hydration benefits.

10. Magnesium and Mineral Water: Calm, muscle-supporting mixers

Magnesium plays roles in muscle function and nervous system balance, and some brands now offer magnesium-enhanced mineral waters. Good Housekeeping’s 2025 coverage notes products that supply measurable magnesium per can. Incorporating mineral water with added magnesium into cocktails can give a mineral-rich mouthfeel and a subtle wellness-forward angle. Pair mineral water with a squeeze of citrus and a splash of fortified simple syrup to create a lower-alcohol highball that feels sophisticated and balanced. Keep portion sizes modest, and if you’re taking magnesium supplements or have kidney concerns, check product labels and consult a clinician. Using mineral water this way is about flavor, texture, and a light emphasis on electrolytes—not a substitute for medical guidance.
