Yes, milk is hydrating. While water remains the gold standard for hydration, studies suggest milk hydrates even better than water due to its unique composition.
Why Milk Hydrates Effectively
Milk's superior hydration capabilities are attributed to several factors:
- Water Content: Milk is approximately 90% water, providing a significant source of hydration. [Source: Real Simple]
- Lactose, Protein, and Fat: These components slow the stomach's emptying rate, leading to sustained hydration over a longer period compared to plain water. [Source: CBS Boston, Harvard Health]
- Electrolytes: Milk contains natural electrolytes like sodium, contributing to better fluid balance in the body. [Source: Organic Valley]
Several studies support these findings:
- A study found that a milk permeate-based beverage is superior to water and traditional electrolyte solutions in maintaining positive fluid balance after consumption. [Source: NCBI]
- Research indicates that milk is one of the best beverages for hydration, even surpassing water and sports drinks. This is attributed to milk's natural electrolytes. [Source: GonnaNeedMilk]
Milk vs. Water for Hydration
While milk offers superior hydration in certain aspects, water remains essential for overall health. Milk is a good hydration option, especially during warmer months when dehydration risk increases, or following physical activity.

Conclusion
Milk is a good source of hydration, offering advantages over water in terms of sustained hydration due to its composition. However, water remains crucial for overall health and well-being.
