What To Look For When Buying Protein Powder
When you are looking to purchase unflavored protein powder (or any protein powder), there are a few factors to consider.
Ask yourself how you intend to use the protein powder – is it for bulking or cutting? Look at the source of protein and what it tastes like.
What are your main purchase criteria?
Value
If you want to get as much protein powder as possible without overspending, consider using a whey concentrate protein powder.
Whey protein concentrate is slightly less refined than whey isolate, but contains more carbs and fat and less protein due to the refining process.
However, this is not necessarily a bad thing. If you want to gain mass, then the extra carbs and fat likely won’t matter much to you. If anything, the extra carbs and fat will help you reach your goal sooner.
Avoiding lactose
Dairy products aren’t for everyone. If you are lactose intolerant and consume dairy products, you will likely end up with digestive problems. Vegans also choose not to consume dairy out of personal preference.
Being vegan or lactose intolerant can make finding a protein powder difficult, but not impossible. There are still a few protein powder options suitable for vegans and those allergic to dairy.
Whey protein isolate is effectively lactose-free, as it contains milk protein and all of the essential amino acids found in milk without the lactose. During the refining process, 99% of the lactose is filtered out, so you can consume it even if you are lactose intolerant.
If you are vegan, you should consider plant-based protein powders. Pea protein powders are a popular choice for vegans, but brown rice protein powders are also an option.

Best quality whey protein
If you want whey protein of the highest quality in your protein powder, you should consider whey protein isolate. Whey isolate has a higher protein concentration and contains less carbs and fat.
If you are cutting, you should use whey isolate instead of whey concentrate. Otherwise, you will need to cut more carbs and fat out of your regular cutting diet, as you will be consuming them in your protein powder.
Clean products
If you are very concerned with what you put into your body, then you will want a clean protein powder. In this case, the term clean refers to whether the products are tested for contaminants and contain the ingredients that they claim to.
The best protein powder brands in this regard are Kaged, Naked Nutrition, and Transparent Labs. While you may pay slightly more for products from these brands, you know that you will be paying for quality and peace of mind.
All the protein powder made by these three brands goes through rigorous third-party testing for heavy metals.
Choosing your protein type
Whey concentrate
Whey concentrate is the most common type of protein found in protein powder. It is made from cow’s milk and, as a result, contains lactose. It is a good choice if you want to gain mass, as it contains some extra carbs and fat.
It is also a good choice if you want to get the most bang for your buck. You can get large quantities of whey concentrate protein powder cheaper than other protein powders.
Whey isolate
If you are lactose intolerant but still want to use whey protein powder, take a look at whey isolate. It has the same essential amino acids and protein as whey concentrate without lactose, so it is much easier on the stomach.
It also contains fewer carbs and fat than whey concentrate, so it will make your life much easier if you are cutting. It is slightly more expensive than whey concentrate because it is more refined and a higher quality version of whey.
Pea protein
If you can’t consume dairy due to allergies or choose not to because you are vegan, pea protein is a good option to consider. Protein powders that use pea protein generally only consist of one ingredient: the peas the protein is extracted from.
Its protein concentration is lower than whey protein powders, so you’ll often need to consume more if you want to get the same amount of protein.
Casein
Casein is another protein source derived from milk, consisting of 80% casein protein and 20% whey protein. Casein protein differs from whey as it is digested at a slower rate, so it feeds your cells with amino acids over a more extended period.
For this reason, it is best to consume casein protein powder before you go to bed on a day you have trained. Unfortunately, it won’t be suitable if you are lactose intolerant, as it does contain some lactose.
Soy
Soy protein is another option to consider if you are vegan or lactose intolerant. It is extracted from soybeans and doesn’t have that many amino acids, which is why many vegans prefer protein powder derived from peas.
Nevertheless, it is still another popular protein option to consider if you can get amino acids from another source.
Other ingredients and flavoring
Flavor
You will likely consume protein powder every day if you are training. This means you’ll want to choose a protein powder that tastes good to you; otherwise, drinking it will end up being a chore.
Some unflavored protein powders taste quite pleasant by themselves, but most people prefer flavored protein powders for a reason. If you want an unflavored protein powder that still tastes good, MyProtein’s Whey Protein Isolate is a good choice.
Sugar
Sugar makes a lot of food and drinks taste better – and there is no disputing that. However, it is not necessarily a healthy ingredient that you would like to see in a protein powder.
If you are bulking up, don’t be too concerned about drinking a protein powder with some excess sugar. Excess sugar will be a problem if you are cutting, however.
If you are worried about consuming excess sugar, consider an unflavored protein powder. These often contain less than one gram of sugar per serving and shouldn’t interfere with your cut.
protein
When choosing a protein powder, the most obvious thing to look out for is how much protein it contains. If you are training and on a strict diet, you will likely already be consuming a significant amount of protein.
Therefore, you will need to consider how much more protein you want from protein supplements. Consuming too much protein can cause health issues, so figure out how much protein you need based on your weight and height.
We will go into more detail about how much protein you should consume later.
Avoid amino acid spiking
Amino acids are an essential part of any diet. However, you should steer clear of protein powders that include additional amino acids to inflate their protein content.
While these additional amino acids technically count as protein, they are not suitable for building muscle. The best way to tell if a protein powder has extra amino acids to inflate its protein figures is by checking the ingredients.
These tell-tale ingredients are:
- Glycine
- Arginine
- Glutamine
- Creatine
Benefits Of Unflavored Protein Powder
We have already discussed some of the benefits of unflavored protein powder; in this section, we’ll go into a little more detail.
Can be included in baking recipes
If you’re tired of drinking your protein powder every day, there are more interesting ways to consume it. Unflavored protein powder is excellent for cooking and baking, as it doesn’t have enough flavor to affect the taste of food.
Adding protein powder to pancakes, oatmeal, waffles, brownies, and other delicious food items keeps things fresh and boosts your protein intake. If that sounds like something you’d like to try, don’t miss our guide on the best protein powders to mix with oatmeal!
Add your own flavor
It’s easy to get tired of your protein powder if you’ve been drinking it every day for months on end. However, if you are cutting and don’t want to add your unflavored protein powder to baking recipes, there are some other options.
Using unflavored protein powder means you can add different flavors to it every day, depending on your preference. Some great things to combine with your protein powder include peanut butter, cinnamon, fruit, cocoa powder, and even vanilla extract.
While it is possible to mix flavored protein powders with these ingredients, it will limit your options a little. No one really wants to combine a root beer-flavored protein powder with banana and peanut butter.
Often contains fewer unnecessary ingredients
If you are cutting and worried about your macros, an unflavored protein powder is an excellent option. Unflavored protein powders don’t contain any additives like artificial sweeteners and artificial flavorings.
Unflavored protein powder also often has less sugar and carbs than flavored protein powders. This can help you track your macros and stick to them.
Cheaper
Unflavored protein powders are generally cheaper than flavored powders, as they contain fewer ingredients. Unflavored powder can also save you money, as you won’t have to purchase a different flavor when you get tired of the old one.
Instead, use one of the above methods to spice things up. Getting enough protein shouldn’t feel like an ordeal for your taste buds.
Protein Consumption Tips
To get the most out of your protein powder, follow the tips below.
When you consume it
There are some benefits to consuming your protein powder an hour before or an hour after a workout. However, don’t fret too much if this isn’t possible. Consuming your protein shake at another point in the day won’t have a significant impact on your strength or hypertrophy outcomes.
Use a macro tracker
Consider using a macro tracker if you want to figure out how much protein you should consume in a day. You can use macro trackers to monitor your calorie consumption and body weight.
These figures can help you work out your TDEE (Total Daily Energy Expenditure.)
Calculate your TDEE
If you want to gain mass, calculate your TDEE and consume 300 to 500 more calories above this figure daily. This will not be applicable if you are cutting.
Protein content
Aim to consume about 0.7 grams of protein for every pound of lean body mass. This means you’ll need to calculate your body fat percentage and deduct the weight of your body fat from your overall mass.
Bulking
If you are focused on gaining a lot of mass, mix your serving of protein powder with 16 oz of whole milk. This adds 300 calories and another 16 grams of protein to your protein shake.
There are other ways to add calories to your protein powder, such as adding coconut oil, raw honey, or any nut butter.
If you want to add extra protein without all the extra calories, use 16 oz of skim milk instead.
FAQs
No company currently makes a protein powder without any flavor whatsoever – it isn’t really possible. Even unflavored powder still has some taste to it, which usually comes from the protein source.
For example, whey protein often has a vaguely milky taste to it.
But, practically speaking, the protein powders on this list are as unflavored as it gets.
No, a protein powder that lacks flavor will not automatically be better than one with a flavor. You should always look at the nutritional information of any protein powder to see whether it will be a good option for you.
Unflavored protein supplements often contain less sugar and carbs, but this isn’t really helpful if you are trying to bulk up. They can be advantageous for baking or adding your own flavoring.
This will depend on your training goals. If you are cutting, mix your protein powder with water so you won’t consume any unnecessary calories.
However, if you are bulking, you can mix your protein powder with skim or whole milk.
