Is milk a good recovery drink instead of a protein shake after a workout?

Short answer

Yes. 600 ml of milk (3 cartons of 200 ml) gives about 20 g of protein plus fluid. Over 12 weeks of training, muscle grew more than with a carb drink, and milk kept fluid in the body longer than water.

Is milk a good recovery drink instead of a protein shake after a workout?
'Recovery = protein shake' — does this formula hold?
Many people reach for a protein shake the moment they finish training. But can a carton of milk from the fridge do the job too? We checked three things: muscle, fluids and soreness.
Milk has plenty of protein
600 ml gives you about 20 g
The 600 ml of milk used in a post-exercise study held 20.4 g of protein (210 kcal). In another study, people drank 237 g of milk 1 hour after training, and their leg muscles took up milk's protein building blocks and shifted toward building muscle.
So does muscle actually grow more?
56 people, 12 weeks: the milk group gained more
56 people lifted 5 days a week for 12 weeks. Right after training and 1 hour later they drank fat-free milk, a soy protein drink with the same calories, or a carb drink. Lean mass (muscle and everything except fat) and muscle fiber size grew more with milk than with either drink. Strength was the same in all three.
Another 12-week trial agreed
Lean mass 1.9 kg vs 1.1 kg, fat dropped only with milk
20 people trained 5 days a week for 12 weeks and drank 500 ml of fat-free milk right after and 1 hour after training, or a carb drink with the same calories. Lean mass rose 1.9 kg with milk and 1.1 kg with the carb drink. Body fat fell 1.6 kg, only in the milk group.
Milk also keeps fluid in longer than water
Half as much left as urine
11 people lost 1.8% of body weight in sweat, then drank 1.5 times that amount. Over 5 hours they passed 611 ml of urine after milk, 1,184 ml after water and 1,205 ml after a sports drink. In a study where 72 people drank 1 L each, 4-hour urine was 1,337 g after water and 1,052 g after milk.
But does it ease soreness too?
500 ml right after eased soreness, but damage did not heal faster
32 people drank 500 ml of milk right after muscle-damaging exercise and felt less sore than with a carb drink of equal calories; women also lost less strength. In a trial where 24 people took milk protein 17 times over 4 days, damage did not heal any faster. Milk eased soreness but did not speed up healing of the damage.
It doesn't beat sports drinks by much
Chocolate milk matched other recovery drinks
An analysis that pooled 12 studies on chocolate milk found no difference from other recovery drinks in effort, heart rate or muscle damage markers. Compared with a dummy drink, people lasted 0.78 minutes longer in the next session. In a 2026 trial with 16 people, milk and water gave the same recovery.
Bottom line: milk works as a recovery drink
3 cartons of 200 ml = about 20 g protein + fluid
600 ml of milk (3 cartons of 200 ml) gives about 20 g of protein plus fluid. Over 12 weeks of training, muscle grew more than with a carb drink. Swapping a carb drink for milk also cut the next meal by 73 kcal on average (118 people). The one exception is people who can't digest lactose.
