So, you’ve been hitting the gym regularly and you’re feeling pretty good about your routine. You’ve got your stretches down, your cardio sessions timed to perfection, and you’re lifting heavier weights each week (result!). But there’s one question that’s been bugging you: should you have a protein shake before or after a workout?
This is one of those age-old fitness debates that just keeps popping up so we thought it was about time to do some research and finally answer the question should I have protein before or after workout? Whether you're new to the gym or a seasoned lifter, you’ve probably wondered about the best time to consume your protein shake (I know I have too!). So, let’s dive into the science and see if we can get to the bottom of this, shall we?
Protein Shake Before or After Workout?
The great debate! First, let’s talk about why you need protein in the first place. Protein is essential for muscle repair and growth. When you work out, especially during strength training, you create tiny tears in your muscle fibers (bit weird when you think about it but we move on). Protein helps repair these tears, making your muscles stronger and bigger in the process. That’s why it’s crucial to include enough protein in your diet if you’re aiming to build muscle. Still with me?
So when is the best time to consume it? Should you have a protein shake before or after workout? Well, the answer isn't as straightforward as you might hope, lets dive into the specifics...
Protein Before Workout: The Case for Pre Workout Protein
Let’s start with the argument for consuming protein before your workout, also known as pre workout protein. Some studies suggest that consuming protein before exercise can be beneficial. Here’s why:
- Muscle Protection: Having a protein shake before workout can provide your muscles with the necessary amino acids they need to minimise damage during your workout. It acts like a buffer, reducing the extent of muscle breakdown.
- Energy Supply: Protein isn’t just for muscle building; it can also be a source of energy. Though not as efficient as carbs or fats, having some protein in your system can help sustain your energy levels during a workout.
- Protein Synthesis: Consuming protein before workout might kickstart protein synthesis (the process of building muscle) early on, potentially leading to more significant muscle gains.
Protein After Workout: The Case for Post Workout Protein
On the flip side, there’s a strong case for consuming protein after your workout, known as post-workout protein. Here’s why many fitness enthusiasts swear by this timing:
- The Anabolic Window: There’s this concept called the "anabolic window," which is a short period after your workout where your muscles are like sponges, ready to absorb nutrients and start the repair process (clever right?). Therefore, consuming a protein shake post workout can maximise muscle protein synthesis during this time.
- Replenishment: After a strenuous workout, your body is in a catabolic state, meaning it’s breaking down muscle. Protein after workout helps shift your body from a catabolic to an anabolic state, promoting muscle repair and growth (helping you lift even more next time you hit the gym!)
- Glycogen Replenishment: If your protein shake includes some carbs, it can also help replenish glycogen stores, which are crucial for recovery and preparing your muscles for the next workout too, so win-win!
So, What’s the Verdict? Should you have protein before or after workout? The truth is, both timings have their benefits. It often boils down to personal preference and your specific fitness goals so keep reading to find out how you could benefit from pre workout protein or post workout protein and the main differences for different athletes.
For Strength Athletes and Bodybuilders
If you’re lifting heavy and aiming for maximum muscle growth, you might want to consider both. Yep, you heard that right! Having some protein before your workout can help minimise muscle damage (which if this is your job you want to avoid at all costs) and provide a steady flow of amino acids during your session. Then, following up with a protein shake after workout can optimise the muscle repair and growth process. This strategy ensures that your muscles are well-fed at all crucial times, which is the most important thing for strength athletes. If you are looking to build muscle and your overall strength, then make sure to check out our blog on ‘How to Gain Muscle’.
For Endurance Athletes
If you’re more into endurance sports like running, cycling, or swimming, the timing might be slightly different. Pre workout protein can still be beneficial, providing a small energy boost and muscle protection. However, post-workout protein becomes more critical for recovery and muscle repair after long, intense sessions. Therefore, for endurance-based athletes, a protein shake after workout is more beneficial!

What Type of Protein Should You Choose?
Now, let’s talk about the type of protein. The most popular types are whey and casein, each with its own set of benefits.
- Whey Protein: This is the go-to protein for many gym-goers, but should you have whey protein before or after workout? This type of protein is quickly absorbed, making it perfect for post workout protein shakes. It floods your muscles with amino acids right when they need them the most. If you’re looking to have a protein shake before or after workout, whey is a versatile option that fits both timings well.
- Casein Protein: This protein is absorbed more slowly, providing a steady release of amino acids over several hours. Casein might be more suitable for pre workout protein if you’re planning a longer, less intense workout, or even as a nighttime shake to support muscle repair while you sleep.

What About Weight Loss?
If your goal is weight loss, you might be wondering: should you have protein shake before or after workout for weight loss? Protein can help you feel fuller for longer, which can curb your appetite and reduce overall calorie intake. Drinking a protein shake before workout might help you stay energised and focused, reducing the likelihood of snacking later. Conversely, having a protein shake post workout can aid in muscle recovery and maintain lean muscle mass, which is crucial for healthy metabolism. So, should you have protein before or after a workout regarding weight loss? The choice is yours or you could choose to have both if you wanted to.
Can You Drink Protein Shakes Without Working Out?
A question that often pops up is: can you drink protein shakes without working out? The answer is yes, but with a caveat. If you’re not exercising, your protein needs might not be as high. Consuming protein shakes without working out can contribute to your daily protein intake, but it’s important not to overdo it. Your body only needs a certain amount of protein to function properly, and excess protein can be stored as fat (so be careful!)
Summary of whether you should have a protein shake before or after a workout
To Shake or Not to Shake? To sum it all up, the question of whether you should have a protein shake before or after a workout really depends on your individual goals and workout regimen. If you're aiming for muscle gain, both pre workout protein and post workout protein can be beneficial, ensuring your muscles get the amino acids they need at all crucial times. Endurance athletes might find more value in post workout protein to aid in recovery. If weight loss is your goal, a protein shake before or after workout can help manage appetite and support muscle mass.
When it comes to the type of protein, whey protein before or after workout is a versatile and effective choice due to its quick absorption. Casein is great for a slower release of amino acids, making it a solid option for pre-workout or even nighttime consumption.
The idea of the anabolic window suggests that protein after workout is critical for muscle repair and growth, but having protein before workout can also kickstart protein synthesis and provide energy. If you're wondering, "Should I drink protein shake before or after workout?" or "Should you drink protein shake before or after workout?", the answer is: it depends on what feels best for you and aligns with your fitness goals.
And yes, you can drink protein shakes without working out, but remember to balance your protein intake with your overall dietary needs to avoid unnecessary calorie surplus. Whether it's for gym protein powder enthusiasts or those asking, "Should you have protein shake before or after workout for weight loss?", the key is consistency and understanding what works best for your body.
So, should you take protein before or after workout? It’s ultimately up to you. Experiment, listen to your body, and find the routine that helps you achieve your fitness goals. Cheers to finding your perfect protein shake timing and making those gains, no matter when you choose to shake it up!
