The Isolate Advantage (28g Protein + BCAAs): Unlike standard whey concentrates, our Irish Whey Protein Isolate undergoes a cold-filtration process to deliver 28g of pure protein and 7.9g of naturally occurring BCAAs per scoop. It’s a clean, undenatured choice for those seeking to maximize muscle recovery without unnecessary fillers or fats.
Truly Grass-Fed Certified Sourcing: We don’t just claim it; we carry the Truly Grass Fed seal. Sourced from Ireland, our cows graze on open pastures for at least 250 days a year with no added hormones. This sustainable approach ensures a superior nutritional profile compared to grain-fed alternatives and supports our 1% for the Planet mission.
Zero Bloat, Easy Digestion: Our advanced isolation process removes the bulk of lactose found in traditional powders, making this a naturally low-lactose and easy-to-digest formula. Designed to be gentle on the stomach, it’s the perfect solution for those who experience digestive discomfort or bloating from standard whey.
Lab Tested for Heavy Metals & Purity: Your safety is our priority. Every batch is lab-tested for heavy metals (including lead, arsenic, and mercury) and quality assurance verified for potency. Packaged in the USA, we maintain total transparency so you can trust the purity and protein content in every bag.
Clean Label Promise (Non-GMO & No Stevia): Made with clean ingredients and no artificial sweeteners, flavors, gums, or soy. We use a tiny amount of non-GMO sunflower lecithin for smooth mixing—never amino spiking. It is a pure, undisguised formula that accurately reflects the high-quality nutrition your body requires.

Makes a great, healthy chocolate shake
Good stuff. One of the things I use it for is a chocolate shake that tastes as great as one from a good restaurant, but that is very healthy — no sugar and relatively light on calories and fat. Can be a meal replacement. Here’s the recipe.1/2 cup of almond milk4 frozen almond milk ice cubes (I just use an old fashioned ice cube tray to make them).A frozen banana OR half a frozen medium-to-large apple (cut into chunks and then frozen beforehand).2 scoops whey protein (the serving size on this brand is two scoops).A heaping tablespoon of high quality cacao (or cocoa powder).1 cup of baby spinach (trust me, you’ll never taste it or know it’s there).A tiny sprinkle of salt (another trust me, it makes a difference).One Truvia packet (or equivalent other artificial sweetener).4 drops of liquid Stevia or to taste.Optional:1 teaspoon of Fiber powder. The apple and spinach provide ~4 grams of fiber and the cacao 1 gram, so I don’t add fiber.1/2 teaspoon Lecithin powder. There is some lecithin in the whey but I add a bit for extra thickness and smoothness. Still very good without it.1 tablespoon coconut oil (If you’re on a ketogenic diet and need more fat). If you do add this, the extra lecithin will help blend in the oil.Blend well. Makes a great tasting, thick, smooth shake. The apple and spinach provide 2 fruit/veggie servings per shake. Baby spinach has almost zero taste, but it adds tons of nutrition and just makes the shake a bit thicker. It won’t look green either, just chocolate. Great way to get kids to eat spinach.

Highly recommend.
It’s really an amazing product. No bloating. It’s filling. And the taste is fine, it’s not strong. I have ordered multiple times.

Keeps me full and doesn’t mess with my tummy
I’m usually a snacker, but using 2 scoops of this every day has cut my snacking down so much! I was struggling trying to stay under 2000 calories before using this, but now I’m hovering around 1500 calories per day, without really trying! I use 1 scoop in my morning iced coffee and then 1 scoop in my afternoon iced coffee.It mixes well with my iced coffee and is truly tasteless.Whey isolate is supposed to be fine for people with lactose intolerance and I can attest that this does not hurt my tummy. Also, anytime I’ve ever tried a protein powder, my face broke out, but this has not caused any breakouts for me.UPDATE: after using for 3-4 weeks, I’ve discovered the whey seems to have aggravated a bowel and/or fibroid issue (the two seem to go hand in hand with me). I really liked this, too, so I’m disappointed!

Good Product but Unknown Lead Level
Product delivers on mixing with foods and not altering taste. Have contacted them twice to understand lead levels with no response. Not good sign.

Good Product
Only 2 ingredients that comes from grass fed, hormone free cows. It is important to me how the cows are treated….so win-win! I use it in place of milk on my oatmeal.

Blends well and truly tasteless
Blends well. I like that it is tasteless, I add it to my coffee, smoothies, and baking recipes.

Good quality and mixes well with oatmeal
This protein powder has what you need and nothing extra – which is good. I use the unflavored and mix it in my oatmeal. It mixes in well and you can’t taste it. It mixes in better than other protein powders I have tried.

Buyer beware.
Be very careful. There is nothing on the package telling you where this protein actually comes from. There are no industry standard certifications. It looks like it’s just a shell company packaging low quality ingredients. Buyer beware, and Amazon will tell you it’s not eligible for return when you realize you received a deceptive product.

This is one of the best and cleanest whey protein powder you can get, not additives, not bs. It is very light on digestion, and it has no after taste. It dissolves super well in any type of liquid, and the best part is, you can add any kind of taste you want, perhaps clean and natural. But, it is expensive of course, you can find the exact same mix from CP at half a price.

It’s a best Natural protein in market and sugar free. Plus fast delivery.

This is the cleanest form of protein you’ll find anywhere. It’s isolated* which is a MUST for protein powder. This has absolutely no filler and no bad stuff in there. I mix a scoop in water and add a spoon of organic cacao powder. I have mastered the art of delicious clean high protein shakes!

This protein powder is great, it doesn’t add any taste or smell to smoothies and it’s the only protein powder that doesn’t cause me to bloat
