Reviews – The Best Grass Fed Whey Protein Powders

There is some seriously good competition for grass fed whey protein powders at the moment and narrowing down the list of products to just 8 was surprisingly difficult. But we are confident that the 8 grass fed whey protein powders on this list are all excellent choices.

1. Nutricost Grass Fed Whey Protein Isolate

Often, grass fed whey protein powders are quite a bit more expensive than their non-grass fed rivals. This is to reflect the increased cost of raising the cows. Nutricost has managed to keep their prices extremely competitive though, while still delivering an ethical and ecologically viable product.

The protein powder provides 24 servings of 30g protein per pack. You can choose chocolate, vanilla, or unflavoured powder. The powder mixes well with water, and the chocolate and vanilla powders taste great. The grass fed whey protein isolate from Nutricost is the best overall grass fed protein powder.


  • Excellent value for money
  • High quality protein
  • Mixes well with water
  • 30g of protein per serving


  • Taste is decent, but there are better tasting powders out there
  • Lack of flavour choice

2. Whey Fantastic 100% Pure Grass Fed Whey Protein

One of the cool things about this grass fed whey protein is that it combines three forms of whey protein (isolate, concentrate, and hydrolysate). It also provides 4.6g of BCAAs per serving, and a respectable 22g of protein.

It is low in sugar, mixes well with water, and tastes great. Though the choice of flavours is (just like Nutricost) very limited. The protein powder is also free of soy, free of gluten, and does not use any fillers or preservatives. 

This is as natural a protein powder as you are going to find. Whey Fantastic’s 100% pure grass fed whey protein is the best natural grass fed protein powder on this list. 


  • Free of preservatives
  • Free from gluten and soy
  • Combines isolate, concentrate, and hydrolysate


  • While 22g of protein is pretty average, it is quite low for this list
  • Lack of flavour choice

3. Raw Grass Fed Whey

When you first look at this grass fed whey protein powder, you may think that it is crazy expensive. But when you actually look at the ingredients list, you realise that the 5lb bag contains 90 servings, with each 24g serving containing 21g of protein!

Not only is it surprisingly good value for money, but this is a company that really cares about the welfare of the cows they use to make the whey. The milk comes from Jersey cows (famed for their incredible milk) that graze on grass year-round. 

All of the milk used for the whey comes from sustainable US farms, and the cows eat grass and clover to provide a milk that is rich in omega-3. This will not make much difference to your diet, but it is always great to use healthy, happy cows that have year-round access to grass, clover, and sunlight.

Because this powder is unflavoured, it is by far the cleanest protein powder out there. Just 100% whey! Of course, this has its downsides too. The powder will not mix as well as regular protein powder. And you may want to  combine it with some form of fruit, milk, or sweetener, as on its own the taste (or lack thereof) is uninspiring. 

Use a blender, mix it with some fruit and milk, and you have got yourself a fantastic protein smoothie. This supplement is the best environmentally-friendly grass fed protein powder on this list.


  • Pure whey protein (no flavourings, mixing agents, or preservatives)
  • Very environmentally friendly
  • Protein to carb and fat ratio is excellent


  • Tasteless – literally
  • Does not mix well
  • 21g of protein is quite low for a protein powder

4. Amazon Elements Grass Fed Whey Isolate Powder

Things always get interesting when Amazon themselves start getting into the act. This is not the greatest grass fed protein powder on this list, but it is an incredibly good start. While the cows are absolutely grass fed, they are housed indoors during winter and fed “a diet of grass silage plus a small amount of vitamins and minerals for proper nutrition”.

This is not as good as the previous products. But you have got to admire Amazon’s honesty. Most grass fed dairy farms probably do the same thing, but they do not display that fact on their packaging!

The protein powder itself is decent. 25g of protein per serving is better than the two previous entries, and it tastes better too. This is mostly thanks to the natural stevia leaf extract that they use as a sweetener.

What is great about this protein powder is that Amazon is such a well known and reputable company. The product has a satisfaction guarantee. If you do not like it, then you can get a full refund. That is why we have chosen this as our best trusted grass fed protein powder


  • Excellent satisfaction guarantee
  • Decent protein per serving
  • Delicious taste using natural sweetener stevia


  • Cows are only free to walk during spring, summer, autumn
  • Does not mix particularly well

5. Garden of Life Whey Protein Isolate

There is quite a lot to like about Garden of Life’s whey protein isolate powder. It has 24g of protein per serving, 6g of BCAAs and 4g of glutamine. The cows are hormone free, and grass fed. The protein powder is also designed to support your immune system. 

The only real downside is the small number of servings per pack. Considering the price, having only 20 servings per container is a bit annoying. You could easily get through 20 servings within a week! 

There are two options for flavours: chocolate, or vanilla. Thanks to its high BCAA and glutamine content, we believe that this is the best recovery grass fed protein powder


  • 6g of BCAAs
  • 4g Glutamine
  • Chocolate flavour is surprisingly good


  • Only 20 servings per pack
  • Lack of flavour choice
  • Does not mix well

6. BN Labs Grass Fed Whey Protein 

One really cool thing about this product is that they sell small tester packs of five servings. A great way to decide for yourself whether BN Labs’ grass fed whey protein is the right choice for you. Of course, you will almost certainly fall in love with it.

This is by far the best tasting grass fed protein powder on this list, with both vanilla and chocolate being incredibly tasty. It is also a good source of protein, with a more than respectable 24g of protein per serving. 

The only downside is that compared to others on this list, the calories per serving are a little high. 160 calories per serving compared to a rough average of 110-120 calories. But that almost certainly contributes to the unreal taste, and it is not as if 160 calories for 24g of protein is bad. This is pretty standard within the industry.


  • Amazing taste
  • Respectable protein content
  • Mixes well


  • High calories per serving compared to others on this list
  • Lack of flavour choices

7. ProMix Nutrition Undenatured Grass Fed Whey Protein

The grass fed whey protein from ProMix Nutrition is quite expensive. But what you are paying for is an extremely high quality product. This whey protein is cold processed, and micro-filtered making it the best digesting grass fed protein powder

The powder is independently tested by a third party, which ensures that each batch is of the same standard as the previous. It is also made from the milk of cows who live on family farms in California. So, you have got that ecological and ethical benefit too. 

There is also a decent variety of flavours. You can choose from unflavoured, vanilla, chocolate, peanut butter, and chocolate peanut butter. 

The only downside is that it is 160 calories per serving and while 25g of protein is decent, there are alternatives that offer more per serving.


  • Lots of flavours available
  • Great tasting
  • Independently tested by a third party
  • Digests well


  • Expensive

8. Naked Whey 100% Grass Fed Whey Protein Powder

While the price of Naked Whey is about the same as the price for ProMix Nutrition, you get an extra 15 servings for your money. There are also less calories per serving and the same amount of protein (25g). 

There are five flavours available: Chocolate, matcha, strawberry, unflavoured, and vanilla. Other than the flavourings (usually organic coconut sugar) the only ingredient present is grass fed whey. If you get the unflavoured version, then that is all you get. 100% grass fed whey protein powder.

Obviously, this means that the powder is more likely to clump and is not going to mix as well as protein powders that add ingredients to prevent these issues. Again, the cows come from family farms in California, and are GMO, soy, and gluten free.

There are loads of recipes that Naked Whey have developed to go with their protein powder. Which makes this the best grass fed protein powder for cooking and baking


  • Great flavours
  • Great tasting
  • Lots of fun recipes to try out


  • Expensive

Buying Guide – How To Choose The Best Grass Fed Whey Protein Powder?

Now that you have a list of the 8 best grass fed whey protein powders on the market. It would be a good idea to know what to look out for when browsing. 

What Makes Grass Fed Whey Protein Better?

When it comes to nutrition, there are not too many differences between grass fed and grain fed. You will still get excellent value for money and a similar amount of protein per gram. The differences are more ecological and moral.

Grass fed cows are not fed hormones, they lead happier, healthier lives, and that can be reflected in the finished product. Whatever your stance on veganism vs regular dieting is, you can agree that cows spending their lives eating grass and being able to roam around in fields is a good thing.

Grass fed whey protein is higher in a fatty acid called conjugated linoleic acid (CLA), but as CLA is pretty inconsequential to your diet this is not much of a selling point.

If you decide to go for grass fed whey protein powder, then just know that your choice has led to happier cows and a smaller ecological footprint. The health benefits are no greater than those of regular whey protein.

Tip #1 Read the Fine Print

If you look at our review of Amazon’s Elements protein powder you will see that the grass fed label can mean different things. Amazon makes it clear that while the cows they use do spend the majority of the year grazing in fields, during winter they are actually housed indoors and fed grass that was harvested during summer.

This is a fairly standard and practical way to care for cows. But it is up to you whether this counts as true grass fed cows or not. 

Many dairy farmers keep their cattle indoors during cold weather, particularly frost. But cows are more than capable of surviving cold weather, and cows raised in California are hardly going to need to be kept away from winter weather. 

Amazon’s solution is practical, and it is probable that most grass fed whey protein uses the same methods. But if you are dead set on cows that are allowed to graze year round then be sure to check the labels.

Tip #2 Check the Protein to Calorie Ratio

To be fair, this is good advice for any form of protein powder, be it grass fed whey protein, vegan pea protein, or regular whey protein. While it is not the only proof of quality, finding a grass fed whey protein powder that has a high protein to calorie ratio is definitely beneficial.

Remember, protein is 4 calories per gram. Take ProMix Nutrition, they have 25g of protein per 160 calories serving. That means that out of 160 calories, 100 calories come from protein and 60 calories come from fats and carbohydrates.

Compare that to Nutricost’s protein powder which has 30g of protein (120 calories) per 140 calories serving. Meaning that there are 120 calories from protein and 20 calories from fat and carbohydrates. 

Now, not everyone needs to worry about the protein ratio, but if you are dieting then this can make a huge difference. Luckily, all of the products on this list have a particularly good protein to calorie ratio. But it is certainly something to look out for. 

Tip #3 Check the Price per Serving

Because whey protein powders are often sold in completely different sized packages, and use different serving sizes, it can sometimes be confusing. Is this a good price or not? The best way to work it out is to find out the cost per serving.

Then, you can take it a step further, and work out the cost per gram of protein. This can help you to differentiate between a protein powder that uses filler ingredients, and is high in fats or sugars, and a protein powder that is high in good quality protein.

Remember, grass fed whey protein is going to cost more than dirt cheap whey protein. This is because it is more expensive to produce and is a higher quality product. However, that does not mean that you cannot find a good deal out there using the price per serving method. Buying in bulk usually helps lower this price. 

Tip #4 Do Not Compromise on Taste

One downside to grass fed whey is that there are not often many choices when it comes to flavours. You are often forced to decide between unflavoured, chocolate, or vanilla. There are several reasons for this.

Most people who purchase grass fed whey protein powders are doing so as they want them to be as free from artificial ingredients as possible. Which makes it difficult to add flavour. 

Another reason is to keep costs down, as the quality of the whey protein is so high, it can already be quite expensive. Adding several flavour options can increase the cost of production.

The thing is though, you need to consume as many as 90 servings of this product. That is not going to happen if you do not like the taste! Pay attention to reviews, purchase smaller batches, and experiment with different flavours.

Worse case scenario? You still do not like the taste. In that case you had better get creative with your blender and some interesting fruit juices, or sweeteners.

Final Thoughts

Choosing grass fed whey protein powder is a great decision. It will help to promote ethically sourced whey protein, and it can also help the environment by reducing your carbon footprint too. The grass fed protein powder industry is still relatively small, and if it gets support now then we can hopefully see improvements in flavour and variety. 

The health benefits of grass fed whey protein powder over regular whey protein powder are negligible. But whey protein powder (both grass fed and non-grass fed) has so many health benefits already that this is not really a problem. 

Finding the best overall product out of these 8 grass fed protein powders was surprisingly difficult. But due to its high protein content and overall quality we have chosen Nutricost Grass Fed Whey Protein Isolate as our best overall supplement. 

ProMix was a worthy runner up due to its excellent variety of flavours, and Raw Grass Fed Whey is also up there due to its superior ethical and environmental benefits.
