Why add grass fed whey protein powder to your diet?

While whole foods rich in protein are ideal for health, they aren’t always practical or feasible with busy lives or if you are too fatigued to eat. That is why whey protein can be a big boon to health.

Grassfed whey protein powder can be an easy “whey” to fill in some gaps in your diets for amino acids like branch-chain amino acids, tryptophan, healthy fats like CLA, and L-carnitine for energy support. 

Branch chain amino acids (BCAAs) are amino acids that are naturally found in grass-fed whey protein. Research shows that they help with improving muscle growth after resistance exercise [R].

And research shows that whey protein supplements can reverse muscle loss and frailty

If you find yourself eating a lot of pasta and carbs, a protein powder may also help you with appetite control and also help you build lean tissue instead of fat tissue. 

Caution: if you have a dairy allergy, you should choose a pea protein powder or another low-allergen type of organic protein powder, such as organic water lentils.  Make sure to choose natural protein powders and avoid overly processed soy protein isolates with GMOs. 

How is whey protein made?

 Cow’s milk has two kinds of protein: casein and whey protein. How is whey protein made? 

  • Separation of milk: To separate casein and whey, milk is simply heated and then separated by enzymes.
  • Saving all milk components: Whey protein is the by-product of cheese making so that none of the precious protein of milk is wasted.
    • The casein is used to make cheese while the liquid whey is then filtered and dried to become a powder.
  • Cheese by-product-This is one of the reasons that whey protein concentrate is considered a type of sustainable food.  It is a by-product of cheese making. Prior to the 1970’s it was tossed and considered waste!

How are Organic and Grass-Fed Whey Protein Powders Different?

Should you choose certified grass-fed whey protein powder or organic whey protein powder? Or bother spending more than conventional whey on either

The differences between grass-fed whey protein and organic are clear because it is more beneficial for the ecosystem than standard whey. Additionally, grass fed cows have a higher concentration of healthy fats called CLA, or conjugated linoleic acid.

There are some other important distinctions to be aware of between grass-fed and organic whey protein.

  • Grass-fed whey protein is the whey protein that comes from cows fed strictly on a natural diet of grass.  Cows are meant to graze on grass and not eat in a feedlot with grains. Grass-fed beef is the healthiest beef.
  • Certified grass-fed whey protein or 100% pure grassfed whey protein takes it a step further, requiring 100% grass as a sole source of nutrition.
    • This is the “whey” nature intended because cows are fed a natural diet of grass.
  • Organic whey protein-Chemical free because the cow’s milk comes from cows without the use of pesticides or herbicides. Organic does not necessarily mean that the cows are fed the best diet or most natural diet for their health. It will also be free of GMO sunflower lecithin and all GMO ingredients.
  • Certified organic grass-fed whey protein powder is the type of whey protein that meets the strict criteria for certified organic and is also from verified sustainable cows. It is also hormone-free.
    • *This is the ideal choice for whey protein powders because it is the most nutritious and free from potentially dangerous chemicals.

Grass-Fed Whey is Better than Conventional Whey

Happy grass fed cow by the Healthy RD

Grass-fed protein is a better choice for your health and for sustainable agriculture as well.  The following sections are the reasons why it is better and even healing for the environment to choose grass-fed whey.

Grassfed cows are not raised on CAFOs

Most conventional farms have cows mature in what are called CAFOs (Concentrated Animal Feeding Operations), which are feedlots that mass feed cows, mostly with grains of soy and/or corn.

Most CAFOs are unsanitary, which requires the cows to be injected with antibiotics to avoid sickness. Additionally, cows are often pumped full of steroids for increased growth and beef output.

On the other hand, grass-fed protein powder will have NO feedlot time ever. 

Grazing cattle is better for them and for you

Grass-fed cows are raised in a more traditional manner, free to graze the fields and eat naturally grown grass.

This is obviously more expensive, as the requirements for fertile land are far superior to those of a feedlot.  Organic grass-fed whey protein derived from cows raised in the most natural way is the cleanest whey protein out there.

The best grass-fed whey protein will also have nutritional differences.

Bonus:  Grass-fed beef is a natural fertilizer for plants.

Why Choose Organic Whey and Grass-fed Whey?

Crops of plants require animals for the best ecology and soil enrichment.  A healthy ecosystem can not be one without the other [R].

Whey proteins can be good for you and for a healthy planet too.

But, when we want to choose the best protein powder for our health as well as a healthy environment, there are a lot of things to consider.

  • While a vegan diet may seem at first glance to be the only way to save the planet, we need to consider plant fertilization and soil ecology too.
  • Plants need fertilization, and this fertilizer should NOT come from a chemical fertilizer bag, according to the Agriculture Sustainability Institute.

 Grass-fed cows help the soil sequester carbon, retain moisture, and support a healthy soil ecology.  This is also known as humus.

A complex ecosystem will include healthy animals as well as plant diversity to thrive. Sustainable agriculture, including certified grass-fed beef, certified grass-fed whey protein, and cheeses, can fit into a healthy diet too. 

Note: always choose whey protein powders that use cold processing.  This also helps avoid added chemicals. Cold processing also lends itself to the best-tasting protein powder. 

Grass-Fed Whey Protein Nutrition

Grass-fed whey protein benefits are numerous.  This is because most grass-fed cow farms do NOT use and don’t even need to use antibiotics, steroids, or pesticides, which have been found to pass down damaging effects to humans with the consumption of cow byproducts.

This leaves you with pure, unadulterated whey protein. Here are some nutritional differences between conventional whey protein and grass-fed whey protein [R].

Fat Quality

To get the benefit of the healthy fats in a whey protein, make sure to choose whey protein concentrate, not whey protein isolate.

Omega-3s (made up of DHA and EPA) are fantastic fatty acids that are vital to proper cognition and mood, as well as decreased risk of heart disease. Grass fed whey protein concentrate contains healthy omega-3 fatty acids.

CLA (conjugated linoleic acid) is another fatty acid found in the highest amounts in grass-fed whey protein. Research shows that CLA may be helpful in reducing cancer risk, reducing body fat, and aiding in weight management [R].

CLA content is higher in grass-fed cows than in feedlot cows [R].


Glutathione is the body’s primary antioxidant and grass-fed whey protein labels claim that grass-fed contains a lot more than standard whey proteins.

Protein quality

Essential amino acids- grass-fed whey protein contains all essential amino acids to support building lean body tissue. So does conventional whey. 

Antioxidant content

Antioxidants-grass-fed animals contain higher amounts of antioxidants, including beta-carotene, lutein, Vitamin A (retinol), vitamin E (tocopherol), and phytol from chlorophyll.

Branch-chain amino acids

According to AGN Roots, grass-fed whey protein almost always has more branch chain amino acids than conventional whey protein. These types of amino acids are essential amino acids that support healthy muscle building and help reduce weakness and frailty in older adults.
