Let’s face it—you want to get the most out of your workouts, and adding whey protein can make all the difference. But with so many options on the market, which one really delivers the results it promises?
In this guide, we’ll take you through the best whey protein powders, starting with our top pick, Kion Clean Protein. Whether you’re bulking up, slimming down, or aiming to maintain your muscle mass, there’s a whey protein supplement out there for you.
Best Whey Protein Supplements in 2024 - Quick Overview
Whey protein may sound like something out of a lab, but it’s actually a natural byproduct of dairy production—specifically when milk is turned into cheese. During this process, the milk separates into curds and liquid, with whey in the liquid portion.
So, what’s the hype all about? Well, it’s one of the best sources of high-quality protein available, full of essential amino acids your body may not produce on its own. That’s why it’s such a go-to for fitness enthusiasts and anyone looking to boost their protein intake.Advertisement
But here’s the thing—whey protein doesn’t just build muscle. It’s easily absorbed by the body, which makes it great for recovery after workouts, maintaining muscle mass, or even adding a bit of extra protein to your daily diet. Plus, because it comes in powder form, it’s super versatile. You can throw it into smoothies, shakes, or even your morning oatmeal!
How Does Whey Protein Work?
Whey protein delivers a hefty dose of essential amino acids—the building blocks your body uses to create muscle, repair tissues, and support immune function. When you consume whey protein, it’s quickly digested and absorbed, making it perfect for those post-workout moments when your muscles are screaming for fuel.
Once it enters your bloodstream, the amino acids from whey protein go to work—repairing and growing your muscles. They patch up the tiny tears in your muscles that happen after exercise, making them stronger in the process.
There are other benefits to whey protein, such as regulating appetite, supporting your immune system, and even improving your body’s ability to produce hormones and enzymes.
Types of Whey Protein
There are many types of whey protein, each with unique properties that cater to different needs and goals. Let’s take a look at some of the most popular ones:
Whey Protein Concentrate (WPC)
WPC is the most commonly used form, offering a nice balance between protein content (typically 70 to 80%) as well as fats and carbohydrates. Because it isn’t super processed, you get a bit of everything that naturally comes with whey.Advertisement
The best part? It’s affordable, effective, and has a smooth taste, making it a favorite for beginners or those looking for a more natural protein source.
Whey Protein Isolate (WIP)
WPI goes through more processing to strip away most of the fat and lactose, leaving you with a protein content of 90% or higher. If you’re lactose intolerant or just looking to cut back on carbs and fats, this is your go-to form of whey.
It’s fast-absorbing and lean—perfect for those focused on muscle building or trimming down. Additionally, it’s great if you’re strict about your macros and want something super clean in your shakes.
Whey Protein Hydrolysate (WPH)
WPH goes through a process called hydrolysis, which breaks down the protein into smaller peptides, making it super easy for your body to absorb. In short, it’s predigested for you.
Why would you go for it? Your body has to do a lot less work to digest this type of protein—ideal if you’re really pushing your body in intense workouts or competitions and need something that will get to work instantly. Also, WPH is gentle on your stomach, so if you struggle with digesting other proteins, WPH could be your best bet.
Native Whey Protein
Native whey protein is the purist’s choice; it’s extracted directly from milk rather than as a byproduct of cheese making. This kind of whey is as close to nature as you can get—it hasn’t been exposed to heat or chemical treatments.
What do you get out of native whey protein that makes it different? Because it’s less processed, it contains more intact amino acids. Plus, it can be slightly higher in leucine, which is the amino acid for muscle growth.
Grass-Fed Whey Protein
Care a lot about how natural and sustainable the food you consume is? Grass-fed whey comes from cows that graze on grass or forage rather than being fed grains. Besides being better for the cows, it also means the protein you’re getting is higher in nutrients like omega-3 fatty acids and antioxidants.
It’s also seen as a cleaner option since grass-fed cows are typically raised without hormones or antibiotics. If you’re all about clean eating and sustainable sourcing, grass-fed whey protein is the way to go.

If you're a fan of sweeter protein shakes, it might be perfect for you [7].
Here are some of the most important factors to consider when choosing the best whey protein products:
Calorie Amount
Calories matter—whether you’re bulking up or slimming down, the amount of calories in your protein powder can impact your results. If you’re looking to gain muscle mass, you might not mind a few extra calories per serving. But if weight loss is your goal, choose a protein powder with a lower calorie count to avoid sneaking any unnecessary energy that can slow you down.
Protein Content
This is a no-brainer—the higher the protein content per serving, the more your muscles will thank you. Ideally, look for a whey protein powder that offers at least 20 grams of protein per serving, with the higher-end options packing 25 grams or more.
Carbs and Fat Content
Most of the best whey protein isolate supplements have few carbs and fats, which is great for anyone following a low-carb or low-fat diet. But if you’re using protein powder as a meal replacement, a few grams of healthy fats and carbs might be exactly what you need for a more balanced option.
Protein Type
Look through our protein type breakdown above to choose which protein best suits your dietary needs.
Taste and Flavor
Even the best whey protein won’t do much for you if you can’t stand the taste. Protein powders come in various flavors—from classics like vanilla and chocolate to fruity blends and more. The more your taste buds like it, the more consistent you’ll be in using it.
Price
Higher cost doesn’t always mean higher quality. Compare the price per serving rather than just looking at the total tub cost. Some premium options might be worth the investment for their purity and added benefits, while more budget-friendly, simpler options can still offer great results if you’re mindful of the ingredients.
Using whey protein powder is simple, and the best part is that there’s no one “right” way to do it. It’s all about finding what works best for your lifestyle and fitness goals.
Most people start by mixing a scoop of whey protein powder with water or milk for a simple post-workout shake. It’s quick, effective, and gets the job done. But why stop there? You can also blend it into smoothies with fruits, greens, and nut butter for a more filling option that’s packed with nutrients.
Whey protein powder is so versatile that you can get creative with it. You can add it to your morning oatmeal, pancakes, or even homemade protein bars. It’s an easy way to sneak in extra protein without overthinking it.
4 Key Benefits of Whey Protein Powder
Whey protein powder has many benefits. It’s not just for bodybuilders but anyone looking to improve their nutrition.
1. Muscle Building
First, let’s talk about muscle building. Whey protein is loaded with essential amino acids, especially leucine, which plays a big role in muscle growth and repair [8]. So, if you’re hitting the gym hard or are just trying to maintain lean muscle as you age, whey protein makes the process much easier.
2. Weight Loss
But it’s not all about bulking up. Whey protein can also help with weight management. It’s super filling, which means it can help curb those afternoon snack cravings or late-night munchies. Plus, it’s low in calories but high in protein, so it can keep you feeling full longer without derailing your diet goals.
3. Immune System Support
Another perk? Whey protein supports your immune system. It contains immunoglobulins, which are proteins that help strengthen your body’s defense mechanisms [9]. While you’re feeding your muscles, you’re also giving your immune system a little boost.
4. Heart Health Support
Finally, whey protein can even support heart health. Some studies suggest it may help lower blood pressure and reduce cholesterol, thanks to its bioactive peptides [10].
Potential Side Effects of Whey Protein Powder
Though generally effective for most, whey protein powder can cause some side effects—especially if you overdo it or have certain sensitivities.
Digestive Issues
The most common complaint? Digestive issues. If you’re lactose intolerant or sensitive to dairy, you might experience bloating and gas buildup or an upset stomach after taking whey protein. For those with lactose problems, you could try any of the best whey protein isolate products (one that has less lactose) or even a lactose-free version.
Dehydration and Kidney Strain
Another thing to remember is that too much protein without balancing it with other nutrients might lead to kidney strain or dehydration. Make sure you drink enough water throughout the day—and remember that moderation is key.
Allergic Reactions Like Itching
Some people also may have mild allergic reactions, though these are rare. If you notice any symptoms like itching or swelling, it’s best to stop using whey protein and consult with a healthcare professional.
What to Avoid in Whey Protein Supplements
Now that we know what to look for, it’s just as important to know what not to put into your body. Let’s look at some red flags you should watch out for before hitting the “add to cart” button.
Artificial and Harmful Ingredients
Nobody wants a protein powder that reads like a chemistry experiment, right? Steer clear of products packed with artificial sweeteners, colors, and preservatives. While these ingredients may improve taste or shelf life, they could cause unwanted side effects like digestive discomfort or headaches. Instead, pick products with simple and natural ingredients.
Excess Carbs and Fat
While minimal amounts of carbs and fats are fine—especially if you’re using the shake as a meal replacement—too much can turn your post-workout shake into a calorie bomb. Be sure to check the label and aim for protein powders with minimal carbs and fats unless you’re deliberately bulking or following specific diet plans.
Untested Supplements and Proprietary Blends
Transparency matters. Avoid whey protein that includes untested or undisclosed ingredients, often hidden behind the term “proprietary blend.” These blends can be a gamble since you don’t know exactly what you’re putting into your body. Reputable brands will be upfront about what’s in their products, including third-party testing results for safety and purity.
FAQs on the Best Whey Protein
Here are some of the most common questions about whey protein.
What Is the Best Form of Whey Protein?
