Best Unflavored Protein Powder

Protein powder is an excellent supplement for people who want to build lean muscle mass and lose weight. It can also help vegetarians or people on a strict diet who may not be getting enough protein. However, it is essential to check the nutritional content of the protein powder you buy and choose the best product suitable for your needs.

How can you do that? Read on and find out!

How Do You Choose the Right Protein Powder?

First, it is essential to look for a protein powder that tastes good. If you don’t enjoy the taste of the powder, you’re unlikely to stick to it. Unfortunately, most of the unflavored protein powder available does not taste good (leave it at that).

While you can use unflavored protein powder in smoothies, not everyone wants those extra calories; if you did, then the flavored option would be better.

Most hardcore gym rats like ourselves buy unflavored protein because it has slightly fewer calories than its flavored counterparts and also because we can stomach bad-tasting drinks.

However, after devouring hundreds of shakers full of unflavored protein powder, we have discovered that you don’t have to settle for the traditionally awful taste if you choose the right brand. Fortunately, we’ve done the heavy lifting and listed the best-unflavored protein powder you can buy right now.

Not only do they taste better than all the rest we’ve tried, but they also pack a whole lot of muscle-building proteins.

Naked Whey

If you’re looking for a high-quality unflavored protein powder, this is the product for you. It has no artificial flavors, sweeteners, or preservatives, which is perfect for people with sensitive stomachs. You can easily mix it with water or natural juice for a convenient breakfast or snack. The unflavored nature of the powder makes it great for smoothies which is an excellent way to increase your protein intake without compromising your taste buds.

In addition, the powder is made from dairy that comes from grass-fed cows, which means they never receive growth hormones. It does all of this while packing 25g of whey protein and tasting great in the process. So, taking it does not feel like a chore.


  • Naked Whey is a brand synonymous with quality, with its unflavored protein being no different. The powder is made from milk taken from USDA-certified grass-fed cows.


  • Hormone and additives free
  • It contains all the expected essential amino acids
  • Contains 5.9 grams of BCAAs per scoop
  • Excellent packaging


  • Isn’t easy to mix. We found that some of it tends to stick at the bottom of our shakers


BulkSupplements is a brand that has never been known for its excellent packaging, but they certainly make up for that in the quality department. Their unflavored whey protein packs 26g of protein per serving, translating to around 90% protein per serving.

One of the keys to buying and using protein is to get the type that your body can use to build muscle. It all boils down to the amount of whey protein isolate in the jar. Fortunately, BulkSupplements has the right mix of whey protein isolate and hydrolyzed whey protein, guaranteed to give your body the boost it needs. Most of all it’s highly bioavailable.

Since we often tell people never to trust labels, we are happy to report that 3rd party labs have independently tested BulkSupplements’ products for quality. Furthermore, they are manufactured in FDA-certified facilities, ensuring that they adhere to the highest standards.

Whether you are on a bulk or a cut, we recommend BulkSupplements, because it tastes great even if you shake it with water!


  • Excellent bioavailability, which means that the body readily absorbs it
  • Truly unflavored protein powder with some of the lowest percentage of carbs we’ve seen
  • It contains glutamine peptides to help shore up the immune system


  • Packaging can take some getting used to
  • You will want to take a few extra steps to keep the powder away from moisture

Isopure Zero Carb

We have personally used Isopure Zero carb for quite some time and can safely say that it is exactly as advertised.

Packed with 25g of protein per serving, this is the best tasting unfavored whey protein isolate you’ll find in our experience. As we mentioned earlier, whey protein isolate is the best protein you can use to build muscle because it has the highest bioavailability. In other words, your body isn’t wasting half of it.

It is also the perfect protein for anyone who wants to limit the number of carbs they consume when leaning down for a competition or maybe preparing for summer on the beach.

Isopure Whey Protein also hits a homer in the taste department. While it is unflavored, most people who have tried it, including us, agree that it’s one of the better-tasting products out there.

Whether you take it with water or down it with some juice, it is hard to tell if it has any taste. It is perfect for those who complain that their unflavored protein powder tastes like baby formula…don’t ask us how we know this!

You might also want to choose this unflavored whey protein isolate if you’re on the keto diet, mainly because it has many essential vitamins and minerals added to the blend. So, it stands to reason that you will build a great deal of muscle without soldering through the bad taste.


  • Zero carbs make it great for those on the keto diet
  • The unflavored protein powder does not have any taste or smell
  • Gluten-free and free from any genetically modified organisms
  • Being unflavored means, you can add it to protein cookies, custards, shakes, etc.
  • A quick shake is all you need to mix it up.



  • Adding more than two scoops to your shaker means you need to work extra hard on mixing it.


PlantFusion Complete Protein

PlantFusion is a lesser-known brand amongst your garden variety gym rat, but most vegans have heard about the brand, at the very least. We must admit that at first, the thought of a vegan protein powder didn’t sit well with the brawnier amongst us, but after using it for some time, we can safely recommend it.

Not only is PlantFusion amongst the best-unflavored protein powders you can buy right now, but with 21g of protein per serving, the protein content is up there among the best. Thanks to this protein powder being a hardcore vegan do not mean that you can’t build muscle. You should be able to build quite a bit of muscle considering the amount of protein per scoop!

The blend contains L-glutamine, which helps rebuild connective muscle tissue after strenuous exercises. In addition, there is plenty of cynarine and inulin to ensure that not only do you build the aesthetics of your body but also have a healthy liver and stomach.

Despite being derived from solely plant-based protein sources, it still has a healthy dose of branched-chain amino acids (BCAAs) needed to recover from every workout. After all, you will not see progress if you don’t recover.


  • Free from animal products, soy, dairy, and gluten
  • A plant-based powder that’s perfect for post-workout shakes or taken with water before a workout
  • Loaded with BCAAs to fuel your muscles for a full recovery
  • Free from cholesterol and has a low glycemic load


  • It has a bit of fructose in it
  • Some people have reported that the powder has a slightly muddy taste.

ProMix Grass-Fed Whey Protein

Now, this is an unflavored protein by another comparatively unknown brand, but one which is becoming popular amongst gym-goers who understand the value of quality protein intake. The powder comes packed with 25g of protein per serving, with a 120-calorie footprint. This is the perfect unflavored protein blend for people on a cutting cycle or those on the ketogenic diet.

The protein is mainly plant-based, with just 2 grams of carbohydrates, and no fat, making it ideal for people who want to slim down for the summer. The product has been denatured and cold-processed to protect all the vital nutrients, which means you get more lactoferrin, CLAs, and L-Carnitine per serving than with most other protein powders.

The company has also added B12 to the plant-based blend to help with muscle recovery and growth, in addition to a healthy dose of iron to shore up the immune system. After all, we all could do with a bit more iron.

Finally, the best thing is, like the rest of the products we’ve listed here is, it is free from sweeteners, sugar, and fructose with minimal glycemic impact, making it the perfect early morning drink.


  • Pure, vegan-friendly, plant-based protein powder
  • Only 2g of carb per serving
  • No taste whatsoever, which is a good thing!
  • Free from artificial flavors, lactose, sweeteners, gluten, and soy
  • Excellent bioavailability


  • It does not blend as easily as some of the other products we’ve listed here

TGS Whey Protein Powder

TGS sells some of the best flavorless protein powder we have had the pleasure of finishing. The 100% natural whey protein powder blend is perfect for men and women who spend hours at the gym but want to recover soon enough for the next workout.

All ingredients are sourced from US farms, after which they are passed through an advanced filtration system to process the whey without denaturing it.

It is also the ideal protein powder for people who want to lose weight, thanks to each serving amounting to merely 130 calories. While that’s slightly higher than what you get with the competition, it is still a better alternative to products with preservatives and sweeteners.

Most of all, this is one of those flavorless protein powders that taste great, whether you down it with water or add it to your next muscle-building shake.


  • 100% undenatured whey protein blend
  • Ideal for cooking shakes, etc.
  • Helps build muscle
  • It can be used by people on a keto diet


  • The only drawback is that this one contains dairy, so probably stay away from it if you’re allergic.

Pure Label Nutrition Whey Protein Concentrate

You get 24g of pure, cold-pressed, great-tasting protein powder, despite it being unflavored. The protein powder is made from dairy sourced from grass-fed cows, and according to Pure Label Nutrition, it is ideal for maintaining a healthy lifestyle.

Each scoop comes packed with a healthy dose of essential amino acids, organic proteins, and low-calorie content. The powder mixes well in a shaker, a rare quality but very important for us.

Furthermore, this is one of the best tasting unflavored protein powders you can buy. The froth coupled with the pleasant scent of dairy is an experience that’s hard to describe, so tasting is believing!


  • Excellent for anyone on a low-calorie diet
  • It helps to boost the immune system
  • No additives or sweeteners
  • It mixes like a charm
  • Tastes great even when mixed with water


  • This isn’t a good choice for people allergic to dairy.

Final Word

Many people enjoy the taste and versatility of protein powder. However, the flavor of some powders can be quite overpowering and, with others, downright awful. An unflavored powder should be like a blank slate, with a nutritionally rich base and various flavors to choose from. You can create a recipe by adding flavorings of your choice to the unflavored version. However, if you’re concerned about taste, you can purchase powders with artificial flavors.

Fortunately, based on our research and experience with infant formula, we can safely say that the above are the best-tasting unflavored protein powders out there. You can use these for cooking, baking, and blending your own smoothie. Most of all, they cost slightly less than their flavored counterparts and have fewer calories.

As we tell aspiring gym rats, the key is finding what works best for you, in which case we’d suggest that you start with trying Naked Whey!
