Reviews

High quality

"Top of the line whey protein. Mixes very well and tastes great. I love that it’s sweetened with stevia instead the artificial stuff."

"Love all the nutrabio products!"

Levin I. (5/5)

My favorite!

"I love this protein so much! It mixes well and tastes great! My only issue is that it’s not back in stock and hasn’t been for months! Please tell me you are making more! It’s sooo good!"

Nicole (5/5)

By far the BEST protein powder on the market!!

"This is the best protein powder I have ever taken! I stayed away from whey because I thought it bothered my stomach, but this one is so clean and not full of added junk!! I take this daily and have not had any stomach issues! No bloating no gas nothing! This is also one of the VERY FEW out there on the market that has natural sweeteners, no sucralose!! Do you know how hard it is to find anything without sucralose in the nutrition store or any line aimed at working out or fitness!!??? I am so thankful they have made this product so clean AND it tastes fabulous!!! I add mine to water only and a tbsp of PB fit peanut butter it’s amazing!! I will be a customer on subscription for life with this product!!!"

Kevin C. (5/5)

Grass fed whey

"Phenomenal taste!"

Rode (5/5)

Grass-Fed is the clean 'whey' to go

"I'm a big proponent of clean & grass-fed whey protein powders. This one is exceptional though expensive for me. The chocolate is great tasting although a bit watery at recommended dosage (8 oz). Therefore, I add a bit of whole milk to counteract that (3 oz milk/5 oz water). However you like it, it does the work feeding muscle and pleasant to drink. I'm hoping NutraBio creates a grass-fed Casein protein for bedtime."

Cagle (5/5)

Great tasting product

"The first time I ordered this was through Amazon, but I’ve quit them. When I started running low I searched and found the company. I really like adding this product to my morning oatmeal. The taste is very good and it mostly dissolves with little gritty feeling. I will continue ordering this through Nutrabio. com as needed."

Q&A

Frequently Asked Questions

What makes NutraBio Grass Fed Whey Protein Isolate “grass‑fed”?

NutraBio Grass Fed Whey Protein Isolate is made from the milk of free-range, pasture-raised cows that are grass-fed and never treated with hormones or antibiotics. We use Truly Grass Fed™, a premium dairy protein from Ireland, ensuring a cleaner, more nutrient-rich, and environmentally responsible source of protein.

What sweeteners are used, and does it contain sugar?

NutraBio Grass Fed Whey Protein Isolate is sweetened naturally with monk fruit and stevia, and contains no added sugar or artificial sweeteners like aspartame, sucralose, or acesulfame potassium.

Is grass-fed whey protein isolate healthy?

Yes, NutraBio Grass Fed Whey Protein Isolate is a clean, high-quality protein that supports muscle growth, recovery, and overall health. It’s rich in essential amino acids, naturally occurring BCAAs, and beneficial whey fractions, while being free from GMOs, hormones, antibiotics, and artificial ingredients.

What is the difference between grass-fed whey and normal whey?

Grass-fed whey comes from cows that are raised on a natural, grass-based diet, resulting in a cleaner, more nutrient-dense protein with higher levels of omega-3s, CLA, and antioxidants. Traditional whey may come from grain-fed cows and often lacks the same purity and nutritional quality.

Is grass-fed whey anti-inflammatory?

Yes, NutraBio Grass Fed Whey Protein Isolate contains higher levels of omega-3 fatty acids and conjugated linoleic acid (CLA), which are known for their anti-inflammatory properties, making it a smart choice for muscle recovery and overall wellness.

When is the best time to take this protein?

The best time to take NutraBio Grass Fed Whey Protein Isolate is post-workout to support muscle repair and recovery, or anytime during the day when you need a clean, fast-digesting protein source to fuel your performance or meet your daily protein goals.
