15 Best Grass-Fed Whey Protein Powders 2022

(Last Updated On: October 5, 2022)


Any conversation about building muscle, bulking up and reaching fitness goals won’t be complete without mentioning whey protein.

In the same vein, any conversation about whey protein will lead to, ‘should I take normal whey protein or grass-fed whey protein?’

First-timers will wonder what the difference is between regular whey and grass-fed whey. The answer is simply- grass-fed whey comes from grass-fed cows, which means none of the bad stuff that comes from milk sourced in captivity.

You know the benefits that come from getting more protein (if not, let’s talk about it later), but what about the benefits that come from grass-fed whey?

Thankfully you won’t have to exit this page to see the answer. I’ll outline the plusses of getting your whey from natural, happy sources and why you should make the switch to grass-fed as soon as possible.

I’ll even list the 15 best grass-fed whey protein powders so you can make an informed decision right away!

The 15 Best Grass-Fed Whey Protein Powders

These are the 15 best grass-fed whey protein powders on the market today.


#1. 100% Grass-Fed Whey Protein Isolate by Transparent Labs

100% grass-fed whey protein isolate

I’ve been a fan of Transparent Labs ever since the time I tried their 100% Grass-Fed Whey Protein Isolate. It perfectly embodies what grass-fed whey proteins should be- pure, less processed protein, plenty of beneficial nutrients and free of GMOs, hormones and steroids.

ProteinSeries Whey Protein Isolate is leaps and bounds ahead of the competition. If you’ve read how grass-fed whey has more benefits than regular whey protein, imagine that multiplied by a factor of 10. That’s how potent it is, and only a few brands can offer that claim!

Okay, so let’s get down to the details. Each serving of 100% Grass-Fed has pure 24 grams of protein. Since it’s an isolate and not an isolate, you get less fat and more protein per scoop.

Ingredient potency is all but assured since it’s sourced from grass-fed cows in the US. Let me also point out how there isn’t anything that could ruin the whey protein composition- no artificial preservatives, GMOs, coloring, sweeteners and all that. So when you drink 100% Grass-Fed Whey Protein Isolate, you’re all but assured that you’ll be getting the best protein supplement money can buy.

A quick look at the official website reveals how they’ve managed to add two new flavors into the mix. You can get Strawberry Cheesecake or Cereal Splash, alongside staples such as Vanilla, Milk Chocolate, Salted Caramel and Mocha. As for quantity, there’s one, two or three tubs- personally, I’d recommend 3-tub orders since they offer more bang for the buck (and a discount, too).

Also, be sure to use coupon code TL10 at checkout so you can save 10% on your order.

Pure, clean, and effective. This is what I’d use to describe 100% Grass-Fed Whey Protein Isolate. It is the best grass-fed whey protein available today.


  • Coupon code TL10 saves you 10% on your order
  • Has the purest whey protein content
  • Sourced from American grass-fed cattle
  • Huge discounts on bulk orders


  • Free shipping only in USA
  • Only available on the manufacturer’s website

#2 Grass-Fed Protein from Gnarly Nutrition

gnarly grass fed whey

Up next, we have another top-notch whey protein supplement from Gnarly Nutrition.

Gnarly uses whey protein derived purely from antibiotic-free, non-rBGH grass-fed cow milk.

Their grass-fed whey is loaded with Omega 3s, healthy fats, and each serving delivers 25 grams of muscle-building protein.

narley Whey also delivers pre and probiotics to support digestion and gut health, along with a digestive enzyme mix that improves absorption.

The protein is made to be mixed with water, but I prefer it with mild and blends up smooth and creamy.

We also like that they sell it in travel packets rather than just the tub. The travel packets make it a lot easier for people who are on the go and don’t want to haul some big tup of protein around.

The only real negative with this protein is that it only comes in vanilla and chocolate, both of them are solid, but if you are looking for more exotic flavors, you will have to look elsewhere.


  • 25 grams of protein per serving
  • Delivers Omega 3 Fatty Acids
  • Excellent mixability and taste
  • NSF Content Certified Product


  • Only flavors are vanilla and chocolate

#3. Naked Whey

Naked Whey is grass-fed whey protein, pure and simple. If it isn’t clear enough, here’s what you’ll be getting when you buy the supplement: 100 percent, premium whey protein without artificial sweeteners and additives.

How is whey concentrate better than whey isolate? In Naked Whey, you get the answers right on the brand’s official website. Aside from getting nutritious BCAAs, you also get omega-3s, conjugated linoleic acid, lysozyme, lactoferrin and beta-lactoglobulin in every serving. All those additional compounds make for more lean muscle, less fat and a boosted immune system!

I was pretty impressed at how Naked Nutrition was able to cold process their whey protein and avoid the denaturing process. The protein you get here has a greater bioavailability, which means your body absorbs it faster and turns it into something you can use. Better recovery, energy and muscle growth are just a few things you can look forward to with Naked Whey.

By the way, the whey you get from Naked Whey is from California dairy farms, which is markedly different from ones sourced in the UK, New Zealand and others. Colder climates mean grazing won’t be available year-round, and this isn’t the case with California. As for flavors, you get to choose from Natural, Strawberry, Vanilla and Chocolate Variants.

Naked Nutrition offers interest-free payments and savings when you subscribe to them via a newsletter. It can help bring down the cost especially when you’ve committed long-term.

Don’t let the plain Jane look of Naked Whey fool you- it’s a super potent, grass-fed whey protein powder that comes a close second to 100% Grass-Fed Whey Concentrate.


  • Sourced from dairy farms in Northern California
  • No artificial sweeteners and additives
  • Offers discounts and interest-free installments


  • Plain packaging can put off those who are attracted to in-your-face advertisements

#4 Grass-Fed Whey Protein by Promix
Promix Grass Fed Whey Protein

The one thing that stood out to me when taking Promix’s Grass-Fed Whey Protein was the taste. Their Vanilla, Peanut Butter and Chocolate Peanut Butter were very creamy and needed no additional milk or sugar- just fill ‘er up with ice and water and you can enjoy a nutritious drink anytime!

There are only a few whey protein concentrates that can make my top three, and Grass-Fed Whey Protein easily rounds that out. If for some reason you can’t get 100% Grass-Fed Whey Protein Concentrate by Transparent Labs or Naked Whey then Promix’s whey concentrate should suffice. It’s got a lot in common with them, including a 30-day refund guarantee.

So, where does the whey come from? The answer is heritage breed cows located in North California. Using an undenatured processing for utmost bioavailability, Promix also upholds small-batch measures and third-party testing to prove they have nothing to hide.

There are no fillers, GMOs, hormones, gum, soy, antibiotics, hormones, gluten and stuff that could hinder your fitness goals. The fact that the company gives away 1 percent of its sales to conserve the environment is a nice plus.

Each 5 lb. package contains 75 servings of protein at 25 grams. Rounding out the good stuff are 5.9 grams of BCAAs, Sunflower Lecithin and Maple Sugar as a natural sweetener. For flavored ones they add Raw Cacao and Cocoa, Vanilla and Peanuts for Chocolate, Vanilla and Peanut Butter, respectively.

Grass-Fed Whey Protein by Promix is a solid option for those who want their protein drinks to taste great. The pure whey content is just icing on the cake.


  • Flavored variants taste awesome
  • Excellent bioavailability
  • Has a risk-free guarantee


  • Website a bit tricky to navigate

Available on Amazon


#5 Grass-Fed Whey Isolate byNutraBio

Grass-Fed Whey Isolate byNutraBio

NutraBio’s whey protein product delivers 25g of pure protein in each serving. The company gets their isolate from animal welfare-friendly, antibiotic and rBST hormone-free, environmentally responsible and Non-GMO sources. As such, the whey supplement offers naturally occurring BCAAs and whey fractions such as glycomacropeptides, lactoferrin and immunoglobulins for muscle growth, recovery and repair.

Nutra Bio boasts a fully transparent label that’s free of sweeteners, flavors and artificial colors. Speaking of, you can get it in staples such as Vanilla, Cookies and Cream, Chocolate and something that’s unique, Matcha Latte. Although there’s no soy, there’s Xantham Gum and the label doesn’t show fat, sugar and cholesterol content.

The company has a ‘no compromise’ policy and it shows in their processes. The main factory is in New Jersey and has been inspected by the FDA. You can also check the 3rd party lab test results on Checkmysupps.com, although it’s owned by them.


  • No soy, lactose and artificial flavoring
  • Mixes well with just water


  • ‘Transparent’ label isn’t really so
  • Magnesium content is very high

Available on Amazon


#6 Grass-Fed Whey by MusclePharm

MusclePharm Grass Fed Whey

MusclePharm claims to have hired a team of naturalists, scientists and athletes when they created Grass-Fed Whey. You get the usual slew of wholesome ingredients sourced from cows who eat natural grass all year round.

The process of extraction was done using cold cross-flow microfiltration, which preserves the good stuff and makes it more bioavailable to those who take them. There’s no lactose, cholesterol and fat, but then you get a warning that the supplement may contain allergens in the form of milk. As such, I’d advise you to read the label carefully before you pull the trigger.

MusclePharm keeps things simple in terms of flavor- you get Chocolate and Vanilla, with Vanilla being out of stock. Reviews aren’t that convincing and the price will make you think twice.


  • Chocolate is tasty if a bit too much
  • Tested and passes banned substance test


  • Constantly out of stock
  • Considerably more expensive

Available on Amazon


#7  SFH RECOVER Whey Protein

SFH RECOVER Whey Protein


SFH stands for ‘Stronger, Faster, Healthier’, a company that was established in 2010. Their product, Recover Whey Protein is a supplement that targets joint health, cardio fitness, ATP restoration and muscle building.

SFH Recover is mostly used as a post-workout shake to shorten recovery time and allow you to get back sooner. The SFH promise is about having zero artificial flavors, rBST hormones, GMO components, soy and gluten. Also, keep in mind that this isn’t sourced from grass-fed cows although there are a few extra nutrients such as Leucine, Creatine and Coenzyme Q10.

Recover only comes in 1 bag size and flavors are only two- Chocolate and Vanilla. Instead of coming in a bottle, you get a packet that’s more portable and convenient.


  • Transport-friendly packaging
  • Has Leucine, Creatine and N-Acetyl L-Carnitine


  • Non-grass-fed
  • Only two flavors

Available on Amazon


#8 Sport Certified Grass Fed Whey by Garden of Life

best grass fed whey protein

Garden of Life is a relative newcomer to the whey protein niche but their Certified Grass Fed Whey is already making waves in the US and abroad. One significant difference is the inclusion of the probiotic B.lactis, which supports the immune system and can keep you healthy even when under extreme stress.

What makes Sport Certified different from the others, you ask? its whey is sourced from cows in Ireland and in small herds for eco-sustainability. The country’s inherent climate is said to provide nutritious grass for the animals to feed on. As with most of the supplements here the cows are free to move about and roam all year round. Last but not least, the whey protein is micro-filtered, undenatured, cold processed and free of harmful hormones, GMOs, BSEs and antibiotics.

The only things that let us down is the steep price, the rough texture and the inclusion of erythritol, which can cause unwanted bloating and gas.


  • Inclusion of immune-boosting probiotics
  • Sport certified means no athletic banned substances


  • Expensive
  • Can cause bloating, gas and nausea

Available on Amazon


#9 Grass-Fed Whey Protein Isolate & Concentrate by Opportuniteas

Grass-Fed Whey Protein Isolate & Concentrate by Opportuniteas

Opportuniteas has created two varieties of its grass-fed whey supplement- one that’s concentrate and the other, isolate. You’ll want to pick the right product if you want to achieve your fitness goal. But other than that it’s mostly the same.

Perhaps the biggest letdown of the whey protein is its packaging. Those who will like it will find themselves burdened with many single-pound packets because that’s the only size they have. Yes, you can easily get more but then it’s a waste of time and containers.


  • You can choose from isolate or concentrate
  • 27 grams of whey protein


  • Limited to 1 lb. size
  • Needs additional flavoring

Available on Amazon


#10 Unflavored Grass-Fed Whey by NOW Sports

Unflavored Grass-Fed Whey by NOW Sports

Like our number 9 pick, NOW Sports’ Unflavored Grass-Fed Whey is limited to one size (1.2 lbs.) but that’s where the similarities end.

You get 22g of protein per serving that’s free of antibiotics and rBGH hormones. Although the company didn’t specifically mention where their protein source comes from, they do promise an undenatured and ultrafiltration process for added BCAAs and bioavailability.

The supplement is nut-free, soy-free, paleo-friendly, keto-friendly, non-GMO and free of eggs and corn. You also get a smattering of non-essential amino acids and vitamins and minerals in the mix.


  • Good for vegans and vegetarians


  • Unflavored has a strange aftertaste
  • May cause slight side effects
