Grass-Fed Whey Protein Isolate Powder

Key Features

  • Free of additives & preservatives
  • Sourced from grass-fed dairy
  • Non-GMO
  • Taste

  • Mixability

Whey is a substance produced during cheese production. It is the liquid content that remains after the milk has curdled and coagulated. Whey can be processed and isolated into three different types of protein: Whey Protein Isolate, Whey Protein Concentrate and Whey Protein Hydrolysate. This particular form of Whey Isolate comes from grass-fed dairy sources and contains both milk and soy ingredients.


Serving Size & Timing

The generally recommended serving size of Whey protein is 15 to 30 grams daily. However, the dosage can vary depending on the person's build and body weight, rate of metabolism and size.

The recommended serving size for weightlifters is 1 gram of protein per kilogram of body weight.

Customer Reviews

Mixes well with water
Great Protein that mixes very well with water. I added some different ingredients to improve on the plain taste. I enjoyed this product and will buy again*

Fast shipping Great price
Whey protein only needs one ingredient to have an effect: whey protein. But a lot of protein on the market is dressed up with fancy ingredients that don't really do anything, so it was a relief to find a protein source with no additives or fillers or anything else like that. ”
Why Is It So Important to Choose Grass-Fed?
Many livestock animals are factory-farmed, meaning that they are kept inside factories and fed artificial animal feed and/or grains, which is not their natural food and may have negative effects on the health of the cows and their milk. These animals are likely to live unhealthy, unhappy lives. By choosing a grass-fed protein, you are guaranteeing that what you are consuming is made from the highest-quality milk from cows that live happy, healthy lives, grazing outside on natural pastures, as nature intended. Studies have shown that grass-fed animal products contain higher amounts of many health-promoting nutrients. ”*

best Isolate
This is one of the cleanest, easy mixing isolates at a great value. I buy all my beef as grass fed, why not my whey protein? The flavor is mild and delicious, even plain mixed in water with no other ingredients. I love it too because I can mix it in a veggie shake. *

On 10/5/2016 Julie said...

Great Product & Great Results
I have bought this protein twice and I love the ease of mixability with this product. I mix it with OJ and have never had clumping or any other issues. I use it to replace a meal and leaves me feeling full and ready to get on with my workout, I would recommend it to anyone looking for a pure (non-filler based) protein*

On 8/29/2016 Mario said...

So Pure. If you want healthy Protein this is the best option
I used with milk and it tastes great. The price per gram of protein is great too since most protein powders only offer 20-24g of protein per serving and this is 27! I own a gym and recommend this to my clients!*

On 8/27/2016 Paul said...

This product is perfect for me
I love that this protein does not contain any artificial flavors or colors. I don't like that once you open it, you need to put it in another container because the bag doesn't zip back up. *

On 8/10/2016 Alicia said...

Remarkable Product
I love Whey, great difference in the Grass-Fed Whey. I'm already running right threw it, coming back soon!!!*

On 8/5/2016 Philip said...

Great Product!
I'm so excited to have found this site that sells excellent products at a reasonable price. This grass-fed whey protein powder has no toxic additives and it mixes well. I didn't notice any funky after-taste either. I also love how fast the items are shipped. Keep up the great work Bulk Supplements! I'll continue to recommend your site and products.*

On 7/26/2016 Viorica said...

Great product--great price
This is the 2nd whey protein I have tried from Bulk Supplements & am happy with the taste & texture. Great to keep extra in the cupboard for future use!*

Grass-Fed Whey Protein Isolate Powder
Great product mixes good. Plus fast shipping. I recommend this to anyone wanting a protein powder *

On 7/5/2016 Tommy said...

My favorite
Really love this protein powder. Great taste,. mixes well And, grass fed beef! The best!*

On 7/3/2016 Eileen said...

Unbeatable value!
This is some very high quality whey. I've tried several brands and gimmicks but this grass fed whey is worth the extra price. It mixes very well in a shaker cup and I really like the subtle vanilla taste. I did have some trouble with the bag sealing, but I just transferred it to a rubbermaid container for safe storage. The cleanliness of this powder is amazing and there isn't a bunch of unnecessary additives and other bs. This is what serious athletes and gym goers are drinking because it's quality and that's what you want to put in your body. *

On 6/29/2016 Jared said...

Excellent Protein Source
My Paleo doctor recommended Bulk Supplements because of their purity. I like that it is clean; grass fed, no fillers or additives. My order arrived in a timely manner and I really like the texture and taste. My only issue is that the ziploc seal is difficult to seal so I just clipped it and stored it in a baggie. ;)*

On 6/11/2016 tere said...

Another excellent product
This is the 2nd protein I've tried from and the 2nd that I've been thoroughly impressed with. Just like the 90% Isolate, the Grass-Fed Whey tastes great with or without flavoring, mixes well, and I believe is superior to the name-brand products. I've had no issues with several different shake "recipes" and plan to keep this in my rotation. *

On 6/10/2016 Daniel said...

Very good
I like how it is literally pure protein*

On 6/8/2016 Austin said...

Great tasting whey
I really enjoyed the taste of this isolate. It seems creamier than the usual isolates I have tried. It mixes well and tastes good enough to drink with just water added if needed. *

On 6/5/2016 Erik said...

A Great Whey Protein Isolate Product
This is a good whey protein product. If you're looking for a clean and pure protein source you found it. *

On 4/11/2016 Kevin said...

Probably the best protein shake I've tried: clean, digests well, and does its work. Also helps to know that it's from grass-fed cows.*

On 4/10/2016 Ryan said...

Best protein
This protein is a great quality product that taste great without any fillers.*

On 4/9/2016 Adrian said...

Exactly What I Needed
I am pleased to say that this protein is exactly what I was looking for. Free of any unnecessary sugars or other ingredients. I have nothing bad to say about this this product. My only suggestions for improvement would be to label the suggested serving size in other than tbsp and making the resealing of the package easier. *

On 4/5/2016 Edward said...

Bulk Supplements - Grass Fed Whey Protein Isolate
I've been taking this product for 2 weeks now and I've been very happy with the quality, results, and the taste. It's hard to find grass-fed whey protein for a decent price, and in my opinion this product gets you the best bang for your buck. I'll buy again and definitely recommend to anyone!*

On 3/28/2016 Bruce R said...

Pure goodness, pretty good taste
I looked all over the place for a protein powder that wasn't packed with artificial ingredients, that was affordable, and actually tasted good. For a while I was skeptical that such a thing existed, but this grass fed whey isolate is the genuine article. I've drunk it with only water as well as blended and in both cases it's quite delicious (mixed with water it's kind of like drinking skim milk). It feels really good drinking a protein shake that I know does not have all sorts of hard to pronounce ingredients. Just protein, plain and simple. I highly recommend it.*

Additional Info from BulkSupplements

Great product. Will buy again! I requested more info from bulk supplements on this product and figured I'd share in case you had the same questions.

"The Grassfed Whey is manufactured in the United States, the dairy source is supplied from Idaho. The cows are fed a grass fed diet which is a minimum 85% grass and the remainder being a silage. The product in total in Non-GMO as the Soy lecithin is sourced from Non-GMO soybean."

My Mix: Two stevia packets, Two Tablespoons Cocoa powder, and 28 g of Grass Fed Whey Protien Isolate Powder *

On 3/17/2016 Bruce said...

Grass-fed Whey Protein is Better
First i want to say it was super fast shipping now about the product Grass-fed non GMO Whey Protein Isolate in this price is real bargain Thanks to Bulk Supplements team for quality products*

On 2/28/2016 UMAR said...

Like that it's Grass Fed
excellent product very pure and good quality I just wish bulk supplements would remove the soy lecithin *

On 2/25/2016 Joseph said...

This thing mixes perfectly. Using it for the past week and have no complaints. I purchased the 5kg bag and it comes with 5 individual 1kg bags, which is great to preserve freshness.

I love it and will definitely purchase again.*

On 2/9/2016 Jeffrey said...

Great price and great product!
I have been wanting to get some grass fed whey protein for a while, but it always seems cost prohibitive...enter bulk supplements! The price is great and the product doesn't compromise. I really like that it mixes very well. I usually just add it to my blended protein drink, but it mixes just fine in a glass with a spoon. At first I thought the package sealing strip didn't work quite as well as the silver packaging (this came in white packaging, however, I think there was just some product in the ziplock lines, and after a few uses, it opens and closes perfect. Definitely 5 stars, great product! *

Clean Protein
I was fortunate to find the Bulk Supplement Company and its products in my search for whey protein supplements. With marketing hype, inaccurate labeling, and dubious health claims in the supplement industry, Bulk Supplements delivers quality products at a fair price, and the grass fed whey protein isolate powder is one such product. I will be a returning customer!*

On 1/26/2016 Michael said...

Clean Protein
After some research, I was fortunate to find the Bulk Supplement company and it's products. While the business model is simple: produce pure clean products at a fair price, it's not always easy to navigate marketing hype and health claims in an unregulated industry. The grass fed whey protein isolate powder delivers on both accounts. I will reorder!*

On 1/26/2016 Michael said...

Powered up!
I use this in my bulletproof coffee each morning. Tastes good and gives me the protein needed to stay focused. *

On 1/9/2016 Greyson said...

Great protein at a reasonable price
Getting this protein in bulk with one of BulkSupplement's cycling deals is a bargain when you compare prices for this grass-fed protein to other grass-fed options. It's clean, easy to digest, and exactly as advertised. I will be buying again! :)*

On 12/22/2015 Chris said...

This product is PURE and clean from all the added junk that you see in other products on the market. It mix well with other clean all natural product. Will order again and I will recommend this product and site. *

On 12/20/2015 Roger said...

Way better than the regular Isolate
Prior exp is the regular whey isolate which has a slightly bad aftertaste. In contrast this stuff is much purer; there is only a slight hint of powdered milk taste so it's perfectly fine to drink with water. Also feels easier to digest too. Would 100% recommend paying the premium for this product over the regular isolate. *

On 10/27/2015 Emil said...

Pure grass-fed whey protein powder
So far I am very pleased with this product. I will order more when needed.*

On 10/25/2015 Steve said...

Best price on Grass Fed!!
This has a great price form and the shipping is always fast. This protein mixes very well and taste is not bad at all.*

On 10/16/2015 Adrian said...

Everything I want from a protein powder. No add junk I don't need.*

On 10/12/2015 William said...

Taste and quality!
By FAR the best protein I have used and tasted. The ONLY one I have been able to use with water as the base.*

On 10/7/2015 Patrick said...

Taste and quality!
I have never used a protein powder I could stand with just water. Most powders smell like a chemistry experiment gone bad. This stuff is great! I don't get an insulin spike every time I use it either.*

On 10/7/2015 Patrick V said...

The best Whey Protein I've taken
By far the cleanest supplement I have taken. 27 grams of protein per 30 grams of product speaks for itself. The taste is also pretty good. I was expecting unflavored protein to taste incredibly chalky, and be tough to choke down. I mix 30g with about 10 oz of water and it goes down just fine.*

On 9/18/2015 Brady said...

Nice Lean (but unflavored) Protein
This protein is very lean and has only two ingredients. This is a huge plus if you are counting everything that goes into your body.

The ONLY downside and the reason for 4 stars instead of 5 is the taste. It is unflavored, and thus tastes like whey. I use protein powder in a shaker bottle immediately after my workouts, so flavored options just work better in that regard.

However, if you are mixing this protein with anything like milk or fruit in a smoothie, then it is perfect.


On 9/18/2015 Matthew said...

Great protein!
This whey was exactly what I wanted - a protein staple that I could use without all the added things that come in other companies' pre-flavored protein mixes. It is simple and flavorless. I can easily add it to milk or water to make different types of protein smoothies!*

On 9/14/2015 M said...

Great source of protein without any GMO
The great thing about this protein powder is that it has no flavor so you can add it to anything and flavor it the way you want. Drinking it without a flavor is quite bland but it is GMO free from the label and Grass fed.*
