When you’re looking at whey protein powders…

The last thing you want is a contaminated protein powder with lead and heavy metals.

However when it comes to healthy and clean protein, you’ll appreciate a grass fed source of whey protein.

It may seem unnecessary but when you know your protein source is coming from grass fed cows, you’ll not only have a peace of mind but you’ll also be doing your body a favor.

Especially because the typical cow is pumped with hormones and are fed unhealthy foods. 

The problem is that cows on most farms are fed corn and soy. 

However this is unnatural for cows and can lead to many health related issues. 

There are advantages to choosing grass fed cows, there are a few, but they are not going to be major benefits. 

And really it’s an ongoing debate. 

Whether or not it’s worth it is personal preference. If you feel better knowing you’re getting your protein from grass-fed cows then you’ll probably like grass-fed protein powders. 

Best Grass-Fed Whey Protein

Transparent Labs is a Ohio based company that has been selling top quality supplements for years now. 

They have seemingly grown from zero to where they are now overnight but really it took them years to get where they are. 

Without depending on Amazon or third party sellers, Transparent Labs sells their supplements straight from their own site. 

Their grass fed protein powder can either come in isolate or concentrate. 

Since it is a grass fed protein, we prefer concentrate since it’ll have the healthier fats that grass fed cows tend to have. 

The protein is sourced from New Zealand farms, which is supposed to be one of the cleanest sources. 

In the isolate version of this protein, it contains 28g protein, with absolutely no fat or carbs.

However with the concentrate version, it contains 28g protein along with 6g carbs (3g sugars, 1g fiber), along with 2g fat. 

This isn’t necessarily a bad thing since it’s a concentrate protein powder.

But it is something to keep in mind if you’re lactose intolerant (especially because it doesn’t contain any digestive enzymes) or if you’re looking for a grass fed protein powder without carbs or fats. 

Other than the protein in the concentrate version, it has 3g cocoa, 2.76g chocolate flavoring, 400mg sodium chloride and 125mg stevia for flavoring. 

You should avoid this protein powder if you have severe allergies because it’s made on equipment that makes other products containing eggs, soybeans, shellfish, wheat, tree nuts and peanut oil. 

It’s a completely natural protein powder without any artificial ingredients, and it comes from grass fed cows. 

Although the carb content is a bit high, it’s acceptable for something that doesn’t depend on artificial ingredients or fillers. 

And their isolate version is cleaner with it’s macros.

The grass fed isolate is 54$ per bag, and the concentrate is 45$.

All in all, with completely transparent labels and all natural ingredients.

Transparent Labs protein powders are great choices for those who want to use clean grass fed sources.

Promix is a well trusted brand that uses third party tests to prove it’s nutritional content. 

They make this whey protein from grass fed cows in the farms of Northern California. 

While they aren’t organic certified, they third party test everything from impurities, to allergens and heavy metal contamination. 

Organic certification is expensive and will just increase the cost of the product.

Promix has been selling this grass fed protein for several years and they make high quality supplements that are free from GMOs and are mostly natural.

No hormones or harmful substances are used in the cows that this whey protein is made from. The cows are bred on clean fields, free of pesticides and are located in Northern California. 

Usually, there has to be a downside to all this if it’s all natural and made from grass fed cows, but really we haven’t found anything other than it’s a bit chalky in texture but it can mix easily even in regular protein bottles. 

In every serving there’s 25 grams of protein, 5.9 grams of BCAA’s and only 120 calories. 

Being completely free of chemicals, there’s going to be variance of color in every protein batch due to the natural change of the grass quality throughout the seasons that the grass fed cows eat, but this is normal. 

Since it doesn’t use artificial flavoring or anything other than 3 extra ingredients besides the protein, there might be some inconsistency with flavoring but overall it is a worthy choice of a natural, grass fed protein powder. 

As a bonus, it tests for it’s glutathione content, which is found at 180mg per serving. This is an anti-age, antioxidant that is healthy to have. 



Muscle Feast is an excellent brand that we have nothing but positive things to say about it. 

And we’re not the only ones.

With a 100% score on Labdoor for the concentrate version, and certified pure for the isolate, this proves to be an excellent choice for quality. 

Labdoor is a site where they test supplements for impurities.

By weight, the isolate version is 90% protein, making it one of the purer protein powders by weight. 

The amount of fillers in this protein powder is very minimal and it's actually one of the protein powders that has the least fillers that we've seen so far. 

It only has 4 extra ingredients, not including the whey protein itself and it is mostly for flavoring and texture. 

Muscle Feast has one of the cleanest protein powders we've seen. In fact, this protein powder was made by a married couple for their young son who was disappointed by the lack of quality supplements available.

They built this company to make the cleanest supplements and they've done that so far.  

The isolate is very low in sodium and cholesterol, with only 41mg and 1mg respectively, it virtually has nothing but the protein itself. 

In the concentrate, there’s only 96 calories, which is made up of 18.3g protein, 1.2g carb, 1.8g fat and under 50mg for both cholesterol and sodium. 

Muscle Feast is made with purity and health in mind, without sacrificing for flavoring or extra unnecessary ingredients. 

Here are the ingredients for isolate:

  • 89 Calories
  • 24 Grams Protein
  • 0.2g Carbs 
  • 0.2g Fat 
  • 1mg Cholesterol 
  • 41 Sodium
  • 5% Magnesium / Potassium .3.3.



Naked Whey has gained a reputation for being simply whey protein without the extra fillers or unnecessary ingredients. 

It promises to have only one ingredient, protein. 

This protein comes from 100% grass fed cows, meaning the milk that this protein is processed from is completely clean and the cows are not injected with hormones. 

The cows are raised on small farms in California and they are not subject to small spaced and they roam free on clean fields, free of pesticides. 

Naked Whey is free of additives, coloring, and artificial sweeteners.

Meaning this grass fed protein powder is as close as natural as you can get.

And the unique part of this protein powder is that it’s cold processed, which is a rare thing to find. 

Cold processing helps preserve amino acids, natural nutrients and minerals, so it’s as whole as you can get to natural protein without altering it. 

While it seems to be an organic protein powder, it doesn’t have the certification.

This would make it more expensive and it’s keeping the costs lower for both you and the company to not have it certified. 

There’s another version of this whey called Less Naked whey, which has more extra ingredients to help flavor it.

It’s the same protein, with grass fed whey, but it has natural vanilla flavoring and coconut sugar.



Natural flavors, dextrose, xanthan gum, rebaudioside a stevia, sunflower lecithin, salt, 10% concentrate

Raw makes excellent grass fed whey but it comes at a price. 

It is USDA organic certified. 

This means that the USDA regularly inspects the farms, and the processing to ensure high standards are followed. 

While this is great, there are no GMOs, additives, gluten, soy, or any chemicals for that matter, but it makes it one of the more expensive choices. 

And it doesn’t even come with a scoop or flavoring. 

This isn’t necessarily a negative thing but typically protein powders are bought for convenience and having a healthy choice would make it more expensive since USDA certification isn’t cheap. 

Raw Grass-Fed Whey is made from Jersey cows that roam freely across clean fields. 

Every 25 gram serving contains 21 grams of protein,  2 grams sugar, and 1g saturated fat. 

The other nutrients include 15% RDI of calcium, 3% potassium and 2 percent sodium, and 17 percent cholesterol. 

This is a whey concentrate, meaning it has more fat than isolate, which is what you want from a grass fed whey since the fats contain the healthy benefits that come with this type of protein. 

While this is completely unflavored, it still tastes decent and mixes quite easily.

It reminds us of full cream milk that’s been watered down.

Mixing it with milk will make it taste better. 

Raw Grass-Fed Whey is an excellent whey that has absolutely no artificial ingredients, no soy, gluten and the company provides a full analysis of their protein powders on their site.



Bodylogix is a reputable company that goes by the slogan “Clean. Trust. Performance.” and so far, they seem to follow through. 

Their grass fed protein powder is another choice that has made this list. 

It is free of GMOs, it’s made in a peanut free facility and it is also gluten-free. 

Every serving has 130 calories, 24g protein, 3g carbs and 2.5g fat (0.5g saturated fat). 

The cholesterol is a bit on the high side as it has 25% of daily recommended intake (75mg of cholesterol).

But it is countered with low sodium with only 3 percent of daily intake with a bit of calcium and iron (10 percent and 2 percent respectively).

Since it is a whey blend, not an isolate, it’ll contain carbs and fats. 

It starts with whey concentrate, followed by whey isolate and hydrolyzed whey. 

While it seems like this protein powder would make for a great paleo choice but it has soy, which makes it easier to mix. 

Since the fats are what makes a grass fed protein powder healthier, it’s a good thing that this protein powder is high in fats. 

As a bonus, the container is ecologically friendly as it’s made 100% from recycled , and it’s sweetened naturally. 

While it isn’t completely lactose free, it’s lactose reduced so if you need something that is lighter on the digestive system, this might be the better choice. 

Bodylogix has been in the business since 2009, having more than 10 years in the business making clean supplements makes it easily one of the trusted companies out today. 

Their site has plenty of recipes, making it a neat resource for free protein powder recipes.



Frequently Asked Questions

How We Selected Grass Fed Protein Powders

Protein powders come by the hundreds and the choices seem to be endless. 

While there are so many great ones, we only picked a select few to keep it simple. 

We do earn a commission if you purchase any of them, but the price is the same and none of these companies have paid their way onto this list. 

Our criteria for these powders:

Company reputation – the company must be in business for at least a few years with a positive reputation for clean supplements. 

Ingredient profiles – ingredients must be high quality and extra ingredients like flavoring must be at a minimum.

Manufacturing practices – cold processing is preferred as heat can destroy and lessens the quality of protein powders.

Overall taste and texture – flavoring should be decent and easy to mix. 

Grass fed vs Grain Fed

Typically, Grain-Fed cows are raised in restricted enclosures that are called AFOs, Animal Feeding Operations. 

USDA (United States Department of Agriculture) defines AFOs as confined areas where animals are kept along with their feed, urine, manure and are restricted to a small area of land.

This makes animals prone to sickness and health issues.

These cows are usually subject to loads of antibiotics to counter these common issues. 

Evidence has suggested that these antibiotics are unsafe and can lead to health issues for humans when they consume meat (or milk) from these types of farms. 

For us, that’s protein powder.

It’s possible that consuming protein powder from these types of cows can lead to antibiotic resistance overtime. 

And there’s the issue of hormones and steroids that grain-fed cows are injected with.

However with Grass-fed cows, they are raised in cleaner fields and farms. 

They aren’t injected with hormones and are fed only grass-type diets.

This leads to cows growing slower, thus costing farms more resources and money overtime but it’s believed to be healthier for both the cows and humans in the long run.

Benefits of Organic/Grass-Fed Whey Protein

Grass fed cows are generally healthy due to their fatty acids. 

They have more omega 3 fatty acids, and you’ll benefit more with grass fed concentrate than isolate. 

This is because isolate strips away the fat and you’re only left with the protein content. 

The nutrients and benefits are mostly in the fat content, which is why it isn’t a bad thing to have more fat in this type of whey protein.

Protein Processing: Cold vs Hot

When it comes to the manufacturing practices of protein powders, you'll often see a few terms being tossed around. 

Some include:

Cold processed, un-denatured, cold processed, low temperature drying techniques, micro-filtered, ultra-filtered, etc.

The typical consumer knows some type of filtering or processing is good to see. But there's a difference between heat and cold processing that makes a big difference in the nutritional value.

Some countries require heat to be used in processing dairy related products, however heat processing destroys chemical properties and can make protein form into a cluster. 

Studies have found heat processing to alter the taste of protein powders as a study showed sulfer flavors in whey as well as higher contents of aldehydes, ketones, and sulfure compounds are found in protein powders that are heat processed. 

This is why some grass fed protein powders state whey was made without acid or bleach processing.

Heat processing leads to lower amino acid content along with the reduction of many nutrients.

And cold processing has just as effective treatment for harmful pathogenic microorganisms. And on top of that, flavor is better when it's cold processed.
