(Last Updated On: January 4, 2021)

Getting your protein is important. The thing is, not all protein powders are created equal, not even close.

Today we are going to be talking about some of the best protein powders on the market.

If you don’t know, when it comes to beef, grass-fed beef is the healthier way to go. The same is true when it comes to protein powder.

Whey from the milk of grass-fed cows is superior in many ways to that of grain-fed cows. Let’s learn more about the power of grass-fed cows as well as the top protein powders on the market.

Why Use Whey From Grass-Fed Cows?

When it comes to beef and milk from cows they either come cows that have been stuck in a barn eating grain it’s whole life or from cows that roam the fields eating grass like a cow is supposed to.

Cows that are fed grain are not an ideal source of whey or beef because the grain contains growth hormones and other drugs to make the cows grow larger in a shorter amount of time, this makes the farmers more money. Not to mention the unsanitary conditions they live in which is the reason they need antibiotics as well.

Compare this to grass-fed cows that are out grazing, naturally eating grass as a cow should be. Eating grass, of course, is more natural and doesn’t have the bad stuff that you get with grain-fed cows. On top of that grass-fed cows are higher in key nutrients, including antioxidants, vitamins, and a valuable fat called conjugated linoleic acid that’s been tied to improved immunity and anti-inflammation benefits. It is also 50% higher in the all-important Omega-3 fatty acids which are important for muscle building and recovery.

One thing about products from grass-fed cows is that they are more expensive. This is because the cows take longer to get to full size when they are not pumped full of growth-stimulating hormones.

The Benefits of Using Protein Powder

Now that we have established the benefits of using whey protein from grass-fed cows let’s go over the benefits of using protein powder itself.

Some of the most important advantages include:

  • Easy way to increase protein and BCAA intake
  • Convenient
  • Healthy snack substitute
  • Great for post-post to feed your muscles
  • Fast absorbing source of protein
  • Good for muscle gain and fat loss

Different Kinds of Protein Powders

When it comes to protein shakes there are a few different kinds of protein they use to make them. Whey protein is the most common but there are also other forms of protein out there. These include:

Whey Protein: This form is the most common and fastest digesting. If you are going to get a nice shot of protein after a workout then this would be the one to choose.

Casein Protein: This is a slow-digesting milk protein that some bodybuilders like to take before bed so the slow-releasing protein feeds their muscles all night.

Egg Protein: This is another grade of protein that comes from eggs, obviously. When it comes to digestibility egg proteins are between Whey and Casein. It is low carb and because it is made from the egg whites it is also low cholesterol.

Soy Protein: – This version comes from the soy plant. This one is the worst tasting version of protein powder, unless you like sawdust, in that case enjoy!

Milk Protein: This form of protein powder is dried milk that has had the fat and carbohydrates removed. It is a blend of whey and casein protein just like regular milk is.

Blended Protein: This one is as the name implies a blend of proteins to give you some faster and some slower digesting proteins in a mix.

All of the protein powders we will be covering today will be whey protein, just an FYI.

#4 Grass Fed Whey Isolate by NutraBio

grass fed whey proteinNext, on our list we have Grass Fed Whey Isolate by NutraBio. This one is another good product for you to think about.

This one is actually a lot like our first selection so it is no wonder it is on the list.

Grass-Fed Whey Isolate is hormone, gluten and lactose-free. This one also has a high purity level at 90% and delivers 25 grams of protein per serving. This product also includes 5 grams of muscle-building BCAA’s as well.

It is manufactured in a GMP-certified and FDA-inspected facility so you know they aren’t cutting corners and that everything is on the up and up.

We were unable to find out where the cows are actually located that the whey comes from so that is something we aren’t sure of and may be why the price is lower on this one.

The price tag on this one is $50 per tub making it one of the cheaper products on the list. Reviews on this product are also pretty good.


  • Includes 5 grams of BCAA’s
  • Manufactured in a GMP-certified and FDA-inspected facility

#5 Grass-Fed Whey by MusclePharm

MusclePharm Grass Fed Whey

Coming in fifth place on our list of the best grass-fed whey protein powders is Grass-Fed Whey which is part of the Natural Series by MusclePharm.

This is by far the biggest manufacturer on the list but bigger doesn’t always mean better.

This product is from cows that are fed grass your round, no hormones. This one also doesn’t have any artificial flavors, colors or sugar. One highlight is they use a cold cross-filtration method to remove fat, cholesterol, and lactose giving it an extra high purity.

The knock on this one is they don’t say where the cows are from so that does make us a little leery especially with the lower price tag.

Price on this one is $46.00 for a tub making it the cheapest on the list. They do not offer free shipping though.

Reviews on this one are decent but there are some that do not like the flavor.


  • Cross-filtration for a high purity
  • Well known manufacturer
  • Lowest price per tub on the list

Any Negatives?

    • Not sure what country the cow whey comes from
  • Some bad reviews on taste
