When it comes to improving workout performance and building an overall muscular physique, it often means adjusting protein consumption.
And right now, whey protein is spearheading the competition when it comes to the different types of protein powders on the market.
Whey protein powders are made from skimmed milk and they are easily mass-produced (a byproduct of cheese making), hence its abundance and domination when it comes to protein ingredients.
As good as it is, a downside to whey protein is that some people are lactose intolerant and can’t have dairy, and some people choose not to consume dairy or animal products. Luckily, there is an alternative to whey protein powders in the form of premium vegan protein powders.
To help you find a good product, we’ve researched & compared the best whey protein supplements on the market right now.
How We Ranked These Whey Protein Powders
In our list, we chose the products based on the formula, pricing, variety, and of course, the quality of protein sources.
- The ones that made it to the top 5 all had similar protein qualities, but we also considered accessory ingredients that helped make the product overall better in protein absorption and digestibility or the actual mixing of the shake.
- The ones in the bottom 5 were placed either due to expensive pricing and poor value or just a weaker overall formula. Regardless, these are all bonafide powders in their own rights and will give you a satisfying gym experience.
As mentioned earlier, I’ve had to deal with literally hundreds of these protein supplements, testing them for label accuracy and compliance to regulatory laws. You’d be surprised at the number of supplements we had to skip on because:
- They had poor label transparency or they didn’t state clearly what’s in their powder
- Their website and company appeared sketchy. Basically, the whole website looks like it’s just there as a front and the company doesn’t have a real office.
- Some of the products were either banned or known to test positive for specific banned ingredients
- A few used too many fillers like maltodextrin to compensate for the expensive key compounds
- Poor user reviews in general
Then there’s also the considerations regarding total protein intake vs the number of ingredients in the formula.
One whey protein powder could have 30 grams of protein per 35 gram serving and be really high among single-ingredient formulas. However, a protein complex that provides only 24 grams of protein per serving can be superior if the formula consisted of ingredients that maximize absorption or make the powder more “complete.”
Supplement companies, in general, are all out to take your money with as little expense on their side as possible. So rest assured that the ones on this list are carefully filtered and “purified” with users like you and me in mind.

One of the factors that made them only get top 10 was how their variety of bottles is limited to either 28 or 70 servings, which forces you to subscribe to get a better deal if you don’t plan on using it for a long time. Getting a big tub can also risk clumping over time.

Whey Protein Powder FAQ
What Is Whey Protein?
Whey protein is a form of protein derived from whey. Whey is found in milk and is a natural byproduct of the cheese-making process. If you’ve ever opened up a container of yogurt and noticed some liquid at the top – that’s whey!
During the process of making cheese, liquid whey protein is separated from the other elements of milk.
Producers then process and dry the whey into a powder form.
From there, whey protein is sold in supplement form or added to various foods and convenient protein bars to increase protein content.
Whey protein is very rapidly digested, which makes it an ideal protein supplement for athletes who need a quick boost of protein post-workout. Whey also has a very high amino acid content, which is great for a number of health benefits.
What Are Whey Protein Powders?
Whey protein supplements are simply pure whey protein in their powdered form. Often they will contain flavoring and/or other types of protein to deliver a balanced blend of nutrients.
They are commonly used by athletes, weightlifters, and people on low-protein diets.
Athletes will experience the most whey protein benefits, but in reality, many different people can benefit from taking these products.
The benefits of whey protein are much more extensive than you might think, with many significant proven positive health effects.
What Kind of Whey Protein Powders Are There?
There are a couple of different whey protein types used in these products. The main types are:
- Whey Protein Concentrate: Perhaps the most commonly used form of whey, whey protein concentrate is fast-acting, affordable, and widely available. Concentrate typically contains around 80% protein, although it can vary widely. Whey protein concentrate is also relatively high in lactose, so those folks with lactose sensitivity should avoid concentrate.
- Whey Protein Isolate: Widely considered the best form of whey protein powder, whey protein isolates typically contain 90-95% pure protein. It’s very low in fat, and lactose, so even people who are lactose intolerant can often be fine taking good whey protein isolate powders. Isolate is toted as the “premium” form of whey, and we tend to agree. With that being said, its higher purity and protein content make it a bit more expensive than more affordable alternatives like whey protein concentrate.
- Hydrolyzed Whey Protein: This form of whey involves a protein that has been broken down to increase absorption rates. Basically, long-chain proteins are broken down into shorter chains, known as peptides. This makes the protein easier to digest. Hydrolyzed whey protein is typically fairly expensive, and is not commonly used as the main type of whey, although it may be added to good whey protein blends.
- Mass Gainers: These are not exactly “protein powders” on their own, but they are a supplement that typically includes a lot of protein in them along with other ingredients that help users bulk up. Also sometimes referred to as weight gainers because that’s why most people use them. The best weight gainers will often have servings of protein in the 50-60 g range, which is much higher than a typical protein supplement.
Those are the main three types of whey, although there are others. Many whey protein products will contain a mix of these forms.
What Are the Benefits of Whey Protein Powders?
Whey protein is used by a wide range of people, for a wide range of reasons. While you may immediately think of using it as a helpful bodybuilding supplement when you think protein, in reality, there are a whole lot of different whey protein benefits, such as:
- Excellent source of high-quality whey protein
- Packed with key amino acids
- A high concentration of branched-chain amino acids
They are also usually packed with antioxidants and BCAAs. Branched-chain amino acids (BCAAs) in particular have some very important benefits, and whey is one of the best sources of these amino acids. Some whey protein powders offer the same dosage of BCAAs as many of the best BCAA supplements on the market.
How Can Whey Protein Powder Help Me?
- Muscle Mass: It’s not a whey protein supplement if it doesn’t promise muscle gains. After all, protein is the key macro when it comes to putting on lean mass. The studies about combining whey protein supplementation with regular resistance exercise (as well as aerobic) are solid and are just irrefutable at this point .
- Recovery: The first step in getting big muscles is to first “heal” damaged muscle tissue, and the faster your body heals, the sooner it can get to the “building muscle to prevent this type of muscle damage” part. Whey protein can essentially speed things up .
- Long-term health: Regardless of the source, protein supplementation is more than just simply filling macros. Protein supplements are known to improve antioxidant levels, strengthen the immune system, reduce feelings of hunger, and help regulate blood pressure .
- Weight Loss: While protein powders themselves do not directly affect weight loss like some good quality fat burners do, taking in more protein can help you exercise harder, recover faster and build more muscle, all of which can aid in your weight loss efforts.
How Do I Take Whey Protein Powder?
These products typically come in powdered form. They are generally flavored, although some are unflavored.
For the most part, to take a whey protein supplement you’ll just want to mix it with water, milk, or juice, or mix it into your favorite shake.
At home, many people like to make delicious protein shakes, using a whey protein supplement, plus fruit, veggies, ice, milk, or whatever other ingredients are laying around. Others, who need more calories and protein choose to make their own homemade weight gainer shakes.
If you crave variety, you’ll want to choose a simple whey protein flavor, like vanilla or chocolate, that is flexible enough to mix with a variety of other ingredients.
For on-the-go use, you may want to consider picking up a BlenderBottle. These handy little devices make mixing whey protein into shakes a breeze while out and about.
Blender Bottles have a small metal ball whisk in them that helps mix powdered supplements into water or milk with just a simple shake.
When Should I Take a Whey Protein Shake?
If you’re wondering when to take whey protein powders, that depends on why you’re using them. If you’re taking a whey protein powder as a way to help recover from your workouts, you’ll want to consume a serving of protein immediately following your workout.
In order for your muscles to recover as quickly and completely as possible, they need protein and carbohydrates as soon as possible. So, if you’re heading to the gym, either bring a shake with you (use a BlenderBottle!) or be prepared to take some protein immediately after you get home.
If you are using whey protein as a general health supplement, the timing is of less importance. You can simply use protein powder as a supplement to your diet.
While whey protein is a great way to supplement your diet, note that it is not a complete source of nutrients, so if you’re planning on using it as a convenient meal replacement shake, do some research and speak to your doctor about what else you should be consuming to meet daily nutritional needs.
Are There Any Side Effects of Whey Protein?
When taken as directed, whey protein is a very safe supplement and the vast majority of people don’t experience any notable whey protein side effects.
With that being said, there are some potential side effects, particularly if the supplement is taken in excess, such as:
- Digestive issues, including increased bowel movements, nausea, bloating, and cramps
- Reduced appetite
Whey protein is regarded as a safe supplement when taken as directed. As long as you don’t take too much, you shouldn’t have any problems.
One thing to note is that since whey protein powders are made from dairy, those who are lactose intolerant may experience lactose-related side effects from consuming whey protein.
Whey protein isolate contains significantly less lactose than whey protein concentrate, so keep that in mind if you are sensitive to lactose.
How Do I Pick a Good Whey Protein Powder?
There are a ton of different whey protein supplements out there, so choosing the best one for you can sometimes be a challenge.
- Check the label: The label is your first line of defense against bad products. The label must always be transparent, show the nutritional facts, provide certifications for quality, have labels that prove they’re free from banned substances, and warnings for allergens. Some supplements could have been processed in the same facilities that produce products related to soy, dairy, or peanuts – the three most common types of allergens in the United States. However, these are often easily avoided if you check for claims such as “soy-free” or “non-dairy.” A few products out there could have banned substances. While the usual response is to look them up first, companies can sometimes disguise these banned substances using their chemical or alternative names. Just to be safe, it’s important to look for certifications that guarantee “banned substance-free” formulas.
- Ingredient Quality: Do your research and check if the ingredient included is not only potent but also obtained from clean and quality sources. Also, make sure to keep an eye out for fillers or ingredients you don’t need in a protein powder. As such, the best whey protein in terms of absorption is whey hydrolyzate, but due to its price, many supplement companies may adulterate their product with maltodextrin to add to the total serving size. Some bad whey products also source their protein powders from sources that have questionable quality control, hence the possible presence of heavy metals. Like checking the label, you should always try to be on the lookout for certifications that help tell users that the ingredients are high quality or sourced from places known to have good manufacturing practices.
- Protein Content: First and foremost, take a close look at the ingredient label on any product(s) you’re considering to get an idea of how much protein is in each serving. Typically, you’ll find products in the 20-30g per serving range. Also, keep in mind that some whey protein powders also contain other types of protein mixed in, such as casein. This is not necessarily a bad thing, but it’s something to take note of, and also good casein protein powders exist on their own.
- Dosage: As mentioned, the dosage is subjective but there are papers and personal recommendations from popular strength coaches all over. It’s all a matter of digging deeper into your research. 25 grams of protein per serving may sound like a lot, but you also have to consider how much protein you actually need. These can be based on how intense you exercise or if you’re taking protein as part of a meal replacer. While it’s true there are individuals who need a lot of protein, such as powerlifters & strongman competitors, most users can get by with 0.8 grams of protein per kilogram of bodyweight. This measurement, however, is just the safe minimum and plenty of athletes and fitness enthusiasts need more than the minimum. For optimum muscle growth, an intake of around 1.3 g-1.8 g of protein per kilogram of body weight is recommended. Moreover, consumption of roughly 3.5 g protein per kilogram of body weight can lead to larger muscle mass gains and greater strength increases.
- Type of Whey: There are a few different types of whey protein, each of which offers particular pros and cons. In general, whey protein isolate is the most recommended, but other forms such as whey protein concentrate and hydrolyzed whey protein are also good choices. Many whey protein powders contain a mix of these types to provide a balanced blend of benefits and nutrients.
- Flavor: The vast majority of whey protein powders are flavored. Clearly, you’ll want to find a flavor you’ll actually enjoy – otherwise you won’t want to take it! Since there are a ton of flavors out there, to select a good one for you try to think about how you plan on using it. If you want some flexibility; i.e. you want to be able to drink it straight, mix it in smoothies or toss it in pancakes, go with a simple flavor like vanilla or chocolate. If you’re more likely to just drink it straight mixed with milk or water, go with whatever flavor sounds tasty to you! You can also read user reviews to see what other folks think of the flavor.
- Brand Quality: Since there are so many companies making whey protein supplements, you’ll want to pay attention to the company behind each product you’re considering. Choose products from reliable, trustworthy companies with good reputations. On our list above, we’ve only selected products from excellent and trustworthy companies.
- Value: Whey protein is relatively inexpensive, but if you take it every day it can certainly add up. Typically, you’ll be looking at somewhere between $0.50 and $1.50 per serving, which can translate to $15-$45 a month for daily users. So, take value into account when choosing a product. But, also keep in mind that cheaper does not mean better, so try to find a quality product at a reasonable price.
