Researchers Say Milk Is Hydrating

Milk is a good source of hydration. Researchers compared the effects of a variety of drinks on participants’ fluid balances and compared those results with those of still water in a March 2016 study published in The American Journal of Clinical Nutrition.

Both skim milk and whole milk performed better than plain water in terms of retaining fluids than when participants drank milk.

Patricia Kolesa, R.D., clinical dietitian, says, “Milk is about 90 percent water, meaning it can be a good source of hydration, especially in the summer months where people are more at risk for dehydration.”

Why Is Milk So Hydrating?

The first reason milk is so hydrating is that it’s not water. It may sound backward, but plain water has no calories or nutrients.   Additionally, milk contains electrolytes.

Sarah Schlichter, registered dietitian nutritionist, says, “Milk be a very hydrating beverage option, more so than just plain water, thanks to its electrolyte content.”

Is Milk Better Than Water For Hydration?

With all this information, maybe you wonder if milk is better than water to stay hydrated from now on – or if there is a time when milk is better.

Luis Casaubon, an endocrinologist, says, “milk can be a better option for people recovering from an intensive exercise regimen. Drinking after a workout is great because it contains protein and carbohydrates. Milk can also help reduce muscle soreness after an intense workout.”


A great way to stay hydrated is by drinking milk. Add milk to cereal, add to coffee, or sip on it. However, milk cannot replace water. After a big workout or a long hike, replenish with milk instead of water. You can’t beat water!
