The Best Times to Drink Protein Throughout the Day
As a sports nutritionist, I work with a bunch of athletes and everyday professionals on a daily basis, and a common question I get is whether there is a best time to drink protein.
The short answer is yes.
However, the bigger goal when it comes to our protein intake is whether or not we are hitting our recommended daily intake.
I try to explain to my clients and portray through my content that the bigger picture here is that the best time to drink protein is the time that helps you reach consistent daily protein intake, while still giving your muscles regular doses of the amino acids they need to recover and grow.
That said, timing with your high-protein diet still has value. A well-placed serving can support muscle protein synthesis, make fasted workouts easier to fuel, and close the gap between a hard training session and your next full meal.

What Is the Best Time to Drink Protein for Muscle Growth?
The best time to drink protein for muscle growth is not one exact point in the day. I recommend you start by figuring out your total daily protein intake needs, then spreading it across meals and snacks so your muscles get repeated chances to use essential amino acids for muscle repair.
The International Society of Sports Nutrition recommends servings of about 0.25 to 0.40 grams of protein per kilogram of body weight, generally every three to four hours. For a 180-pound person, that works out to roughly 20 to 33 grams per serving.
At each meal, make sure you're getting quality protein sources that align with your daily intake goals. If you spread things out, you’ll find it much easier to hit your target versus trying to make up for a low daily intake at your final meal.
In a controlled study of trained men, four 20-gram whey servings taken every three hours produced a stronger muscle protein synthesis response during recovery than either eight 10-gram servings or two 40-gram servings.
To simplify your day, look at these as the best time to drink protein:
-
Breakfast: Use it to end the overnight fast and avoid saving nearly all your protein for dinner.
-
Between meals: Add a protein shake, Greek yogurt, eggs, soy protein, or a protein bar if meals leave you short.
-
Around training: Have protein before or after resistance training, depending on what fits your schedule and stomach.
-
Before bed: Consider casein protein if you train late or regularly finish the day under your protein target.
You also don’t need to fear larger servings. The old idea that your body can only use 20 to 25 grams at once oversimplifies the process. A larger meal can still contribute amino acids to your total protein intake, support fullness, and help you build muscle.
If you can’t seem to get in enough protein through whole food options, whey protein is a reliable choice because it is rich in essential amino acids, especially leucine. If you prefer plant-based protein powders, a rice and pea protein blend can work well, too.
That being said, a 2025 study found that a blended plant protein produced a post-workout muscle protein synthesis response comparable to whey in resistance-trained adults.
Should You Drink Protein in the Morning?
Morning protein is one of the easiest wins if you tend to eat toast, fruit, coffee, or nothing at all before noon. It gives you an early contribution toward your daily protein target and can make appetite management easier during weight loss.
Starting the Day with Protein
After 7-8 hours without any food, the body may benefit from a protein source to help replenish amino acid stores. Breaking that overnight fasting window doesn’t need to be complicated. You can simply use a ready-to-drink protein shot like Protein NOW!, which fits into any morning routine with no prep time.
An interesting study compared evenly distributed protein intake with a dinner-heavy pattern, using meals containing roughly 30 grams of protein. The more even pattern stimulated higher muscle protein synthesis over 24 hours, which is a strong reason to stop treating breakfast as an afterthought.
If you train in the morning, a protein shake can be especially useful. Research has also found that eating breakfast before resistance exercise reduced markers linked with muscle protein breakdown compared with skipping breakfast.
Is it Better to Drink a Protein Shake Before or After a Workout?
Many people view post-workout as the best time to drink protein. While consuming protein at that time may not be wrong, there are also benefits to considering pre-workout protein.
Pre-Workout Protein
Pre-workout protein works best as a practical tool, not a strict rule. If your last protein-rich meal was several hours ago, have a light serving before training so amino acids are available while you lift.
Things to consider:
-
Training within an hour of waking: Try a smaller serving that feels easy to digest, such as whey protein, soy protein, or a liquid protein shot.
-
Training after a full meal: You may not need another shake before you start.
-
Training fasted: A light protein serving can be a helpful way to avoid extending the overnight fast further.
Protein NOW! is a perfect option for people who don’t want the volume of a full protein shake before workouts. With 21 grams of protein in a 3.38-fluid-ounce shot, it can easily fit in a gym bag or be consumed during a commute to the gym.
Post-Workout Protein
Post-workout protein helps, especially if you trained fasted or won't eat soon. Still, you do not need to rush to finish a shake in the locker room. Your muscles remain more responsive to protein after resistance training for hours, not minutes.
A 2024 review of 79 controlled trials found that resistance exercise can raise muscle protein synthesis for up to 48 hours, though the size and duration of the response vary by age, training status, and workout design.
Aim for a protein-rich meal or shake within about two hours after training when possible. That window is more practical and helps you start recovery, replenish your routine, and avoid accidentally going most of the day without enough protein.
The 'anabolic window' is best viewed as a wide opportunity, not a 30-minute deadline like we were once led to believe — your gains won't disappear if you miss that window. Your total protein intake and consistent resistance training drive the bigger result. Your total protein intake and consistent resistance training drive the bigger result.
Whey protein is a popular post-workout choice because it is quick and convenient. Even easier is the grab-and-go Protein NOW! protein shot: no mix, no measure, no mess for post-workout recovery.
Does Drinking Protein Before Bed Help Build Muscle?
Drinking protein before bed can support muscle recovery overnight, particularly if you train in the evening or struggle to eat enough protein during the day.
A 2012 study from Maastricht University found that 40 grams of casein consumed about 30 minutes before sleep increased overnight muscle protein synthesis by about 22 percent after evening resistance exercise.
Casein protein digests more slowly than whey protein, which is why it is often used before bed. Cottage cheese, Greek yogurt, milk, and casein protein powder are all practical choices we can eat before laying our head on the pillow.

Option |
Best Use |
Practical Note |
|
Casein protein powder |
Bedtime muscle recovery |
Mix it thicker for a pudding-like snack if a large drink feels uncomfortable before sleep. |
|
Greek yogurt or cottage cheese |
Whole-food bedtime snack |
Add fruit or cereal if you also need carbohydrates and calories for muscle gain. |
|
Whey protein |
Convenient option when casein isn’t available |
It still contributes to total protein intake, even though it digests faster. |
|
Plant protein blend |
Dairy-free choice |
Choose a blend with complementary sources, such as pea and rice protein, to improve its essential amino acid profile. |
We shouldn't force a bedtime shake if it disrupts sleep or causes reflux.A better option is to shift more protein into breakfast, lunch, or an afternoon snack, and then use nighttime protein only when it genuinely improves your routine.
Need something quick before bed? Protein NOW! can serve as a quick final protein serving to finish off a busy day.
How Much Protein Do You Need Each Day?
Your protein needs depend on body weight, training volume, calorie intake, age, and whether you want muscle gain, weight loss, or better muscle recovery.
The federal recommended dietary allowance for healthy adults used to be 0.8 grams per kilogram of body weight, but has now been increased to 1.2 to 1.6 grams of protein per kilogram of body weight daily.
For active people who perform regular resistance training, 1.6 to 2.2 grams per kilogram of body weight per day is a more practical target to support muscle growth. If you weigh 75 kilograms, or about 165 pounds, that equals 120 to 165 grams of protein daily.
Start near the low end, track your intake for a week, and adjust based on how easily you can maintain it. You do not need to chase the top end if 1.6 grams per kilogram already helps you recover well, stay full, and make progress in the gym.

Goal or Situation |
Useful Protein Target |
How to Apply It |
|
Basic adult health |
1.2 to 1.6 g per kg of body weight |
Use this as a minimum baseline, not a muscle-building target. |
|
Muscle growth and resistance training |
1.6 to 2.2 g per kg daily |
Split the total across three to five protein-rich meals and snacks. |
|
Per-meal target |
0.25 to 0.40 g per kg |
A 75 kg person can aim for about 20 to 30 grams at a meal, with some larger servings as needed. |
|
Weight loss |
Often 1.6 g per kg or more |
Prioritize protein at meals to support satiety and preserve lean muscle while calories are lower. |
Don't be afraid to use protein supplements to fill gaps — you don't need to turn every meal into a calculation.
For example, one Protein NOW! shot provides 21 grams, so it can help bridge a gap between meals, while a full meal with eggs, chicken, fish, tofu, Greek yogurt, or beans can cover the rest.
-
Build each main meal around a clear protein source.
-
Keep a portable option available for long workdays, travel, or post-workout errands.
-
Use a barcode-tracking app like MyFitnessPal for one week if you are unsure whether you get enough protein.
-
Drink enough water, especially when increasing protein powders, fiber-rich foods, and training volume at the same time.
Conclusion
The best time to drink protein is any time of day that helps you meet your daily protein intake without adding stress to your already busy lifestyle. For most of us, that means getting protein at breakfast, around resistance training when it’s convenient, and across the rest of the day.
Drink a protein shake after workouts if you need a fast, easy recovery option. Use pre-workout protein when you train fasted or have gone several hours without food, and consider 30 to 40 grams of casein protein before bed if you train late and still need more protein.
Whey protein, soy protein, pea protein, rice protein, egg protein, Greek yogurt, cottage cheese, protein bars, and Protein NOW! shots can all help. Pick the options you enjoy, hit enough protein consistently, and let your training, recovery, and body composition progress guide the fine-tuning.
FAQs
Does it matter what time I drink protein?
Not drastically. What matters most is hitting your total daily protein intake. That said, spreading protein across the day, including around workouts, may better support muscle protein synthesis than consuming it all in one sitting. Timing is a helpful bonus, not a strict requirement for results.
Can I drink protein on an empty stomach?
Yes, you can drink protein on an empty stomach. A liquid protein shot is easy to digest and won't require the prep of a traditional shake. Many people use this as a quick way to start replenishing amino acids after an overnight fast, especially before breakfast or a morning workout.
Is it okay to drink protein right before bed?
Yes, drinking protein before bed is fine. The body continues repairing and building muscle tissue during sleep, so a pre-bed protein source can help support that process. It's also a simple way to close any remaining gap in your daily protein target before the day ends.
