Grass-Fed Protein: 5 Picks and What the Label Means
These grass-fed protein picks are for shoppers who want to know what sits behind the words “grass-fed” on a tub of whey, a meat stick or a carton of broth. The list covers three whey protein powders, one beef snack stick and one beef bone broth. For each one we give the brand’s own grass-fed wording, how far an independent source backs it up, and what the label does not tell you. Below the picks, we explain what “grass-fed” can and cannot mean on a US label. For how USDA reviews grass-fed and other raising claims on meat snacks, see our meat stick label guide.
How we picked
We went through the products on Supercery whose brands describe them as grass-fed and read the exact claim on each brand’s own product page. We then looked for one independent source outside the brand and the big retailers that describes the same product, and we compared the protein per serving where both gave a figure. Where the two sources agree, we state the fact plainly. Where only the brand makes a claim, we say that the brand says it. Where the sources disagree, we leave the figure out. We read these pages on October 27, 2026, and brands update their pages, so the product page is always the place to confirm the current wording. Five products qualified. We have not tasted or tested these products ourselves.
One point applies to all five: none of the brand pages we read names a third-party grass-fed certifier. The grass-fed claims below are the brands’ own statements, backed in some cases by an independent source that repeats them, as noted under each pick.
Grass-fed whey protein powders
Transparent Labs Grass-Fed Whey Protein Isolate
Transparent Labs says its isolate is sourced exclusively from grass-fed cattle raised without growth hormones or hormonal agents. The BarBend review describes it the same way, as whey from hormone-free, grass-fed cows. Both the brand and BarBend give 28 g of protein per serving, the highest figure on this list. The brand page does not say where the cattle are raised, so we do not either. It suits people who want an isolate with a high protein figure per scoop for shakes after training. See Transparent Labs Grass-Fed Whey Protein Isolate.
Naked Whey 100% Grass-Fed Whey Protein, Unflavored
Naked Nutrition says Naked Whey comes from small non-GMO dairy farms where the cows are grass-fed, free roaming and raised without hormones such as rBGH or rBST, and it lists a single ingredient: grass-fed whey protein. The BarBend review also describes it as 100 percent grass-fed whey from small non-GMO dairy farms. Both give 25 g of protein per serving for the unflavored powder. The brand does not name the region its farms are in. It suits people who want one plain ingredient they can mix into oats, smoothies or baking without added flavor. See Naked Whey Unflavored.
Momentous Grass-Fed Whey Protein Isolate
Momentous says its whey comes from European dairy farms where the cows are pasture-raised, grass-fed and not treated with hormones such as rBST. The BarBend review also describes the whey as sourced from European dairy cows raised free from hormones and rBST. Neither source names a country. The brand page and BarBend give different protein figures per serving, likely because one of them reflects an older recipe, so we leave the number out; check the current label for it. It suits people who prefer whey sourced from European dairy. See Momentous Grass-Fed Whey Protein Isolate.
Grass-fed beef snack
Chomps Original Beef Snack Sticks
Chomps says its Original sticks are made from 100% grass-fed and finished beef, and explains that grass-fed and finished means the cattle eat grass their entire lives. Of the products on this list, only Chomps and Kettle & Fire (in a gallery image for its bone broth) use grass-fed and finished wording. We did not find an independent source that confirms it, so treat it as the brand’s own statement. Chomps lists 10 g of protein per stick. The page does not name where the cattle come from or a certifier. It suits anyone who wants a shelf-stable meat snack for a bag, a desk drawer or a hike. See Chomps Original Beef Sticks.
Grass-fed bone broth
Kettle & Fire Beef Bone Broth
Kettle & Fire lists grass-fed beef bones as the main ingredient after water and marks its vegetable and herb ingredients as certified organic. Nourished Kitchen also notes that the brand uses grass-fed beef bones. Kettle & Fire lists 10 g of protein per serving. The brand calls this broth 100% grass-fed, and one Kettle & Fire gallery image says grass-fed & finished beef bones; the page names no origin or certifier. Our bone broth label guide reads this carton line by line. It suits cooks who sip broth on its own or use it as a base for soups, stews and grains. See Kettle & Fire Beef Bone Broth.

What “grass-fed” means on a US label
“Grass-fed” is not one single seal like the USDA Organic mark. On the products above, it is the brand’s own claim, and the wording varies. Some brands say grass-fed, some add pasture-raised or free roaming, and only two use grass-fed and finished: Chomps on its product page and Kettle & Fire in a gallery image. Those words describe different things, so it is worth reading the exact phrase rather than the headline.
The USDA does run a grass-fed program, but it has a narrow scope. The USDA Agricultural Marketing Service Grass Fed Small and Very Small Producer Program is a voluntary program for small producers, those marketing 49 or fewer cattle a year, or lambs from 99 or fewer ewes. Under that program, ruminant animals must be fed only grass and forage, apart from milk before weaning, may not be fed grain or grain by-products, and must have continuous access to pasture during the growing season. It is a standard for producers who sign up for it, not a general rule that every grass-fed label in the store has to meet.
Here is what that means for shopping:
- Grass-fed vs grass-finished: Chomps explains its “grass-fed and finished” wording as cattle that eat grass their entire lives. One Kettle & Fire gallery image says grass-fed & finished beef bones. The three whey brands say grass-fed without the word finished. In every case these are the brands’ own words.
- Look for a certifier: a named third-party certifier on the pack means someone outside the brand checked the claim. None of the three whey brands above names a grass-fed certifier on its product page, and neither do Chomps or Kettle & Fire.
- Hormone wording is separate: phrases like “no rBGH or rBST” or “without growth hormones” are about how the animals were treated, not what they ate.
- Origin is often missing: only Momentous names a region, and only as “European.” If origin matters to you, ask the brand.
Cautions
Whey protein is made from milk, so the three powders are not suitable for anyone with a milk allergy; check each label’s allergen statement. Read the full ingredient list on flavored versions as well. Talk to your doctor before starting a new supplement, especially if you are pregnant, nursing, take medication or have a health condition.
FAQ
Is grass-fed whey the same as organic whey?
No. They are separate claims. Organic has a federal seal and a public database of certified operations, which we cover in our list of USDA Organic snacks and pantry staples. None of the whey powders here makes a USDA Organic claim.
Which pick has the most protein per serving?
Of the figures we could confirm, Transparent Labs gives the most at 28 g per serving, followed by Naked Whey at 25 g. Serving sizes differ, so compare the scoop size too.
Does the USDA define “grass-fed”?
The USDA AMS small producer program sets out a grass-fed definition for the small producers who join it voluntarily. Most grass-fed claims you see on big brands are the brand’s own wording, so read the exact phrase and look for a named certifier.
Is “pasture-raised” the same as “grass-fed”?
They are different words, and a brand may use one, both or neither. Momentous uses both, and Naked Whey pairs grass-fed with free roaming. Read the exact phrase on the label rather than assuming one includes the other.
