The Grass Fed Whey Protein Reviews: Discover Top 7 Natural Supplement Brands for Muscle Building, Better Healthy Living, Physical Balance & Weightloss

Just as meat from grass-fed cows are healthier, so is the milk—and the whey protein you get from that cow’s milk.

Nowadays, more and more people prefer the beef from grass-fed cows, rather than get them from cows that have been reared on genetically-modified foods.

Genetically modified organisms (GMO) in feeds may pose risks to your health and the environment.

So it stands to reason that an increasing number of people now prefer to get their whey protein from such grass-feds sources as well.

The grass-fed whey protein comes from cow’s milk, and plenty of people feel safer knowing that this milk are 100% non-GMO bred.

Benefits of Grass Fed Formulated Whey Protein

Is this just a fad, or a way for people to get on the environmental bandwagon?

There’s an ongoing debate about the issue, but there are good reasons to pick grass-fed whey protein:

  • Better Than GMO Products

First of all, there are legitimate health concerns regarding the use of GMOs for food that people may consume. (1)

The possibility of unpredictable side effects exists, but there have not yet been any long-term studies to dispel such worries.

  • Safe for The Environment

GMOs also pose a significant threat to the environment. (2)

Chemical pesticides and herbicides are usually used with GMOs, and the GMOs themselves may be toxic to various animals. They can upset the ecology in many ways.

  • More CLA Than Whey

The grass-fed whey variety also contains up to 3 to 5 times as much CLA (conjugated linoleic acid) than the regular whey protein.

CLA reduces the amount of fat your body stores, and it also helps your body burn calories efficiently.

  • More Omega-3 Fatty Acids

The grass-fed whey also offers more omega-3 fatty acids.  (3)

These fatty acids fight depression, improve eye health, and reduce the risk of heart disease. It also reduces the symptoms of metabolic syndrome.

Grass Fed Whey Natural for Mass

For Whom is This Premium Supplement Well-Suited?

With the advantages and nutritional contents of grass-fed whey protein, the following people can certainly benefit:

  • Muscle-builders

Protein is perhaps the most important nutrient that anyone who wishes to build bigger muscles will need.

That’s because protein is the raw material that your muscles use to grow bigger after you’ve had a workout.

Whey protein is fast-acting, which is why it is often taken as a post-workout supplement.

You’re able to provide the protein that your muscles need right away while they’re trying to rebuild right after your exertions.

Whey protein is also great for muscle maintenance, especially for women and older people. These are groups of people who may find it difficult to retain muscle as time passes.

The CLA and the BCAAs contained in whey protein also help with muscle repair and maintenance.

  • Those who are trying to lose weight

Protein is a crucial component of any weight loss program, and that’s especially true when you use grass-fed whey protein supplements in addition to a nutritional diet and workout program.

The CLA is certainly helpful, as it reduces the amount of fat your body keeps in storage.

That should help prevent obesity.

As the CLA enables your body to burn calories more efficiently, your body then is more likely to burn fat cells as well.

Whey also works as an appetite suppressant. You feel fuller right after taking your whey protein shake, so you’re not likely to crave additional snacks and sugary treats. You may also keep yourself from overeating during your meals.

Even your muscle-building efforts may lead to weight loss, or at least a lower percentage of body fat. That’s because having bigger muscles can speed up your metabolism.

  • Those worried about chronic diseases

Who isn’t worried about chronic diseases?

As we get older, the possibility of conditions such as heart disease and dementia become more real each day.

But these grass-fed whey protein supplements can help.

This is partly due to the omega-3 fatty acids that are abundant in grass-fed whey protein.

These can reduce the risks of numerous chronic diseases. The other nutrients in the protein powder, including CLA and vitamins A and E, can also fight against cancer.

  • People who need help with diabetes management

Yes, it’s true that if you lose weight and maintain a lean body mass, you lower the risk of diabetes and you may even alleviate the condition.

However, having more protein in the body can improve blood sugars and insulin concentrations. Whey protein is especially noted for reducing blood sugar levels.

  • Those who want to be healthier or at last maintain their health

Whey protein, especially the grass-fed variety, is certainly healthy for you. It contains all the essential amino acids that your body needs.

It is also full of nutrients, and it may have higher concentrations of such nutrients compared to their regular whey protein counterparts.

Grass-fed whey protein often has more vitamin E, B vitamins, magnesium, potassium, and calcium.

Whey protein is also good for your immune system.

The higher concentrations of vitamins A and E make the grass-fed variety even better for your immune health.

  • Those who want to help in protecting the environment

Many environmentalists are wary of the use of GMOs. These are genetically modified in a lab, so they’re by definition unnatural.

Their unnatural-ness can lead to sudden and unwanted changes to the delicate ecological balance of the environment.

The GMOs can be harmful to useful plants and animals. With grass-fed whey, you don’t participate in the use of GMOs.

Grass-Fed Whey vs. Regular Whey Protein: Are There Differences?

At this point, several crucial differences may already be apparent to you, but let’s recap and make the differences more obvious.

Whey protein is protein made from cow’s milk, but the cow’s milk may come from grass-fed cows.

According to the USDA, after weaning a grass-fed cow must exclusively grass, forage, and certain grains while in their vegetative pre-grain state.

They must have continuous access to pastures during the growing season.

As you can see, grains and GMOs aren’t allowed as feeds, even though these feeds may make the cattle heavier (and therefore more profitable).

The focus isn’t on how much money the meat will make, but on the quality of the beef.

The same goes for the whey protein that comes from the cow’s milk.

The milk from the grass-fed cow is inherently healthier and safer, because the cow doesn’t feed on unnatural feeds that may be passed on into the milk and the protein.

The differences are quite noticeable then, between the whey protein from regular cows and from the grass-fed ones.

  • With the grass-fed whey protein, you eliminate the risk of GMOs entering into the whey protein. These GMOs come with health risks, and now you don’t have to put up with those risks at all.
  • Grass-fed whey protein contains more conjugate linoleic acid (CLA, and omega-3 fatty acids.
  • It has a richer amino acid profile, especially with the BCAAs that help your muscles grow bigger.
  • The grass-fed variety has more amounts of various nutrients. These include vitamin E and B vitamins, along with minerals such as potassium, magnesium, and calcium.
  • You’re able to do your part, even in a small way, of contributing to the maintenance of the environment.

Grass Fed Whey Protein vs. Isolate: What Are These Terms

These are somewhat related terms, so it’s better if we define specific words:


The whey protein comes from cow’s milk, and this term specifies that the cow from which the protein comes from has been raised with natural grass.

They’re not raised on grains or other genetically modified foods.

If you don’t see the “grass-fed” term on the whey protein, then it’s assumed to come from regular cows that may have been raised with grains and GMOs.


The milk from the cows is divided into 2 types of protein.

There’s the casein protein which makes up 80% of the protein. The other 20% makes up the whey protein. Whey is fast-acting, while casein is more difficult to absorb.

This makes whey more appropriate for post-workout consumption, as it instantly provides the protein raw material that the muscles need.

It’s also great for breakfast, as your body has fasted overnight and your muscles may need protein.

Casein, on the other hand, is great if you take it right before you go to sleep. It takes longer for your body to absorb, so your body will have a steady supply of protein for your muscles during the night.


Whey protein is generally made into either a concentrate or an isolate.

It is usually a concentrate when you just see “whey protein” in the package label. This has a high concentration of protein, while the nutrients are preserved.

With the grass fed whey protein isolate, the whey protein is purified even further.

The concentration of the protein is much higher. While some of the nutrients are removed, much of the lactose is also taken away so it’s safe for the lactose-sensitive.

Where to Get it Online With Great Shipping & Discounts?

You can buy all of these whey protein powders online. You can try Walmart, GNC, or even Costco. But your best bet is probably just with Amazon.

In, all these are available and you can read plenty of customer reviews about them.

The prices are reasonable, and the site itself is stable and secure. For the grass fed whey protein in UK consumers, Amazon has a UK site as well.


It’s not a fad. Grass-fed whey protein is inherently safer because the cows it comes from didn’t ingest GMOs, and take antibiotics and hormones that can get into the milk and the protein.

It’s just like how healthy pregnant women who don’t take dangerous medications and alcohol invariably have healthier children.

It’s the same basic principle for grass-fed whey protein.
