YES! These 6 Unflavored Protein Powders Are Best for Your Smoothie 

By  Sofia

6 of the best unflavored and tasteless protein powder You Can Feel Good About Adding to Your Smoothie

Do you love eating clean? Do you consider yourself the Smoothie Queen or King? Or do you embrace a high protein, a wheat-free way of eating, cooking and baking?

If yes, then I’m sure you have experienced the frustration of trying to balance the taste of flavored protein powders, with their added flavors, sugar alcohols and sweeteners, against the culinary concoctions you try to create!

Enter the humble, uncomplicated hero…..

Pure protein powder, unadulterated, nutrient dense and a blank slate on which to stamp your own brand of flavor and goodness.

But how do you find a pure protein powder, unflavored and unsweetened?

There are actually many pure, unflavored protein powders out there, all you have to do is go through the labels and find the brands with the least ingredients.

“Oh no! That will take half my lifetime,” you are thinking.

Well, The Good News Is….. I have done the work for you. To save you the time of going through 100’s of protein powders and reading each label, all you need to do is check out my top 6 picks. All quality, all clean, all reviewed with loving attention to detail. And something to suit everyone.

Unflavored vs Flavored Protein Powders

Unflavored Protein Powders are Pure 

Unflavored protein powder trumps flavored protein powder for purity. How so? Because they are free from chemicals, additives, sweeteners, and fillers, you get more protein for your punch.

They Are Versatile

This also makes them better value for money and way more versatile because you can use them in baking sweet or savory meals and add them to smoothies for pure protein benefits.

They Provide More Health Benefits

Many people have developed levels of intolerance to gluten and dairy. They aren’t straight out allergic to wheat or dairy, but because of genetically altered crops, our wheat now contains much more gluten than it used to.

This has messed with the way our bodies work to stay healthy and absorb nutrients. Dairy has also been tampered with, and nowadays dairy products are laced with antibiotics and growth hormones that mimic estrogen, which can cause hormone imbalances.

The Health Issues High Protein Diets Can Alleviate

(Please remember that fiber is also important to add to high protein diets.)

  • Insulin resistance
  • Leaky Gut Syndrome
  • Diabetes
  • Obesity
  • Metabolic Syndrome

These conditions are all precursors to far more serious illnesses like:

  • Cancer
  • Heart disease
  • Early-onset Alzheimer’s
  • Premature aging and death

Who Will Benefit From Unflavored Protein Powder?

Weight Watchers

Decades ago, women began taking “diet shakes” to lose weight fast. These out-dated, proprietary formulas were jam-packed with artificial sweeteners and flavors, fillers, emulsifiers, and additives.

Partly to make them palatable and partly to deliver a host of synthetic vitamins and minerals to compensate for the low-calorie, low nutrient diets women were embracing to lose weight fast.

Protein powders today are so pure, they are great for upping protein intake and keeping people on calorie controlled diets, fuller for longer.

They do not, however, act as meal replacements because they are only full of protein and don’t provide the full range of essential vitamins and minerals needed daily.

They do provide essential amino acids, which are the building blocks we need for robust immune systems.


The bodybuilding fraternity entirely dominates the scene when it comes to protein powders. And many of them aren’t too fussed about artificial ingredients, as long as they get maximum protein, delivered fast, that tastes good.

But a huge number are switching to clean eating and leaning towards purer forms of protein that are organic and natural and free from anything artificial.

People on Specialized Diet

Many people follow diets that restrict them from having certain foods, for various reasons. This has left proteins as a top trending macronutrient, and as a result protein powders now get used extensively in everyday meal planning.

From baking muffins, pancakes and bread to making smoothies and delicious protein-rich coffees and hot chocolates (I have left some simple, quick recipe hacks after the review) Protein powders are used by people who follow these diets:

Vegan, lacto/ova vegetarians, Paleo, Keto, Intermittent Fasting, Banting Gluten free, Dairy free, Diabetics (Sugar-free), Celiac Disease and the list goes on.

So let’s get started: Oh wait, just a few more things...

The Best Unflavored Protein Powder, concerning biological value, is whey. Whey is not suitable for vegans. BUT whey isolate, as opposed to whey concentrate, is usually lactose-free and therefore safe to take if on a dairy-free diet.

About Lecithin

Lecithin is a natural phospholipid that acts as an emulsifier. It helps to bind water soluble and fat soluble ingredients together. It has its own set of health benefits.

Many pure protein powders will be almost 100% pure but will make up the slight difference by adding soy lecithin. This improves the product because it is lecithin that aids mixability. This results in a smooth, creamy texture, whether you drink, bake or cook with it. If you are allergic to soy, some products use sunflower lecithin instead.

Do Not Use For Weight Reduction

Most protein powders will carry this message on their labels. This is because protein powders, especially unflavored, unsweetened, pure powders, do not have nutritional value or fiber. They are pure protein (protein will, of course, provide amino acids).

So while they are great for boosting protein intake and keeping you satisfied between meals they cannot be used as a meal replacement.

Whey Protein Isolate vs. Whey Protein Concentrate

Basically, isolate is ultrafiltered and contains less than 1% lactose, so it is usually safe for people with lactose sensitivities. The concentrate is considered a dairy product, is less filtered and not safe for those people. Obviously, vegans can’t take either as whey is a by-product of the cheese making process.

Best Unflavored Protein Powders -  Top 6 List

I have chosen the best unflavored protein powder made from whey, as well as a variety of other protein powders. Each type delivers excellent quality, easy to digest proteins, and each one has something unique that may appeal to you.

My reviews focus on good, clean products so you will hardly ever see products that are inferior. I believe in giving good choices and don’t feel the need to bring any attention to poor quality or unethical brands. Life is too short to focus on the negative!


Our Rating: 5/5                      

User Rating: 4.6/5

What’s In It?

  • 100% pure, grass-fed whey concentrate.
  • Protein Profile
  • 21g per serving
  • Sizes and Packaging
  • 5lb (2.27kg) resealable bag
  • 25g = 1 serving
  • 90 servings per bag

Raw Grass Fed Whey sources their whey from small farm cows that graze in pastures filled with a mix of wild grasses and clover. This makes their whey really tasty.

Key Points:

  • Heavy metal free
  • Sustainably sourced from farms with pasture fed, free range cows
  • Only 1 ingredient, no added lecithin, zero additives
  • Processed at low temperatures
  • Processed without acids or bleach
  • Soy and gluten-free
  • non-GMO
  • r-BGH and r-BST free

What I Like About This Product

  • Supports immune system
  • Increases energy and promotes the metabolic rate
  • Increases lean muscle mass decreases body fat
  • Enhances glutathione production
  • Promotes joint health
  • Promotes beneficial bacteria in the gut
  • Rich in Omega 3’s and CLA’s


May not mix as easily as whey products that contain lecithin, but the taste will make up for it. It has a creamy texture once mixed, it just takes a bit more elbow grease, so you get an extra workout, just kidding, it isn’t so bad. All it means is you must mix whey with some liquid first and then add more liquid. And for baking mix it in with other flours first. Don’t try mixing it alone with your milk or water, it’s just a mission.

Nutricost Whey Protein Isolate (Unflavored): Best Protein Content Per Serving

Our Rating: 4.8/5                      

User Rating: 4.3/5

What’s in it?

  • 100% Pure Protein Whey Isolate
  • Protein Profile
  • 30g per serving
  • 100mg calcium – 8% DV
  • 110mg potassium -2% DV
  • Sizes and Packaging
  • 5lb plastic containers with screw lids
  • 1 serving = 33.3g
  • 68 servings per container

Nutricost also makes grass-fed whey protein concentrate. It is a great example of the difference between isolate and concentrate. Both are 100% pure but isolate delivers 30g per 33.3g serving while the concentrate delivers only 19g per serving.

Both have benefits. Isolate would suit bodybuilders and do well in smoothies. The concentrate is a perfect additive to gluten-free recipes. And mixes into a beautiful creamy texture.

They also offer a grass fed whey protein isolate, which costs a bit more than the regular whey isolate they make. And it also delivers less protein per serving.

It’s quite impressive that the cows fed on a grain-based diet as opposed to a grass-fed diet will yield higher protein per serving. But it gives you, the consumer, the choice as to what you want in your body.

The grass-fed isolate is also r-BGH free and the regular, high protein, isolate is not. Grain fed cows will be bloated and have bad bacteria in their gut. Grass-fed cows are always healthier and happier. So I would choose a company that only deals with grass-fed products, not one that deals with both, but that’s just me.

This Nutricost Whey Protein Isolate is an excellent choice if you need loads of extra protein every day and want the more affordable, high protein per serving product, especially if you don’t have health issues that require cleaner eating.

It is still a pure product, unflavored and unsweetened, with only 1 ingredient.

Some Tips For Using Protein Powder To Bake And Cook With

  • When baking, substitute 1/3 of flour with protein powder. (p/p)
  • So if a recipe calls for 3 cups, 1 cup must be protein powder.
  • If recipe calls for 500ml flour, use 165ml p/p.
  • If a recipe calls for 500g use 165 grams p/p and 335g other flours.
  • Other flours that you use may be wheat based or gluten-free. If using gluten-free flours add xanthum gum to bind, or eggs or linseed flour.
  • Use 1 teaspoon xanthum gum per 250ml flour. Use 2 eggs if substituting with eggs and use ½ cup linseed flour, if not using eggs or xanthum.
  • If you want the bread to rise, use bicarb instead of baking powder, or find aluminum-free baking powder. If making pancakes, roti’s, wraps or naan type bread omit bicarb.
