Reviews

Truly Lactose Intolerant Friendly

"I used Nutrabio muscle matrix protein back in the day before becoming lactose intolerant, and am still a huge fan of their products. I hadn’t used any whey for years due to lactose intolerance and IBS, I was searching for lactose friendly option. I found that vegan protein also irritated my stomach. After some research, I purchased the whey isolate and it’s certainty as advertised, zero stomach issues with this protein. I really like that you can get it unflavored as well to make it as bland as possible. Highly recommend for folks with sensitivity to lactose and a sensitive stomach."

— John S. (5/5)

Great product

"Very good product dissolves effortless I just wish they had a little better ingredients but taste great also and no issues digestion for the price like transparent labs does and there pricey are better even when subscription"

— Francisco G. (4/5)

Great product

"I really enjoy this, I like to use 2 scoops of the unflavored then add a scoop of the strawberry ice cream iso , the combination works well for me and it mixes perfectly in my shaker with water only."

— William m. (5/5)

Great to be back!

"Long story, but I've been away from NutraBio, Whey Protein Isolate and Creatine Monohydrate for a long time. I'm back, and happy as usual with products and fast shipping. A plus is, my stuff shipped UPS, so I could pick it up at a UPS store. Sorry, porch pirates. Thanks again!"

— Dave L. (5/5)

Great Tasting!

"Great flavor!! I find that the texture is perfect and in Isolate form is much better on my sensitive stomach. Also, easy way to maintain your daily protein intake. I like to blend up my whey protein drink w/ an assortment of fruit- specifically, raspberries and strawberries after a hard workout -maintains my gains. My second choice is Yogurt mixed in a bowl with whey powder and Bear Naked Fruit Medley. Fastest way to get some of your daily protein grams. Thanks for the great service as always!"

— Bill M. (5/5)

Outstanding protien with fast shipping

"Ive been using this protien almost a year now and it never lets me down clean ingredients outstanding flavoe and mixes extremely well i usually get the strawberry shortcake or the chicolate coconut i highly recommend this product"

— Jerry (5/5)

Love the taste and texture

"Love the taste and texture of this protein. This is by far my favorite protein and I have tried them all through the years. I mix my protein with water so the flavor and texture are very important to me. The macros are really good too due to it being a top quality product. The other brands have to use more weight to get the same protein and usually more calories."

— Joey D. (5/5)

The best in the game!

"The only protein I use! Considering I don’t get all my meals in, this is perfect for breakfast, post gym, and late night snacks! I’ve been using this product for years because I’ve only seen true gains with this whey isolate. Any others I tried before, never gave me the lean with TASTE I was looking for! Amazing!"

Frequently Asked Questions

When is the best time to take NutraBio 100% Whey Protein Isolate?

We suggest consuming one serving immediately post-workout when your body is in need of critical nutrients to maximize muscle protein synthesis, which ultimately leads to muscular growth and recovery. It can also be consumed between meals to meet daily protein requirements.

Is consuming too much protein bad for your kidneys?

Absolutely not. This is a myth. There is no scientific literature that shows that eating a high-protein diet has any detrimental effects on renal function in otherwise healthy individuals.

How should I stack NutraBio 100% Whey Protein Isolate with your other products?

We suggest taking one of our versions of PRE 30-45 minutes before your workout, Intra Blast during, and 100% Whey Protein Isolate immediately after.

Can't I meet my daily protein requirements through a regular diet?

While it is possible to meet daily protein requirements through a balanced diet, some individuals find it difficult to get the 1.5-2 grams per kg of body weight necessary to maximize muscle growth and promote recovery. This is why individuals often turn to whey protein supplementation as a convenient way to meet their individual protein needs.

Are whey isolates superior to higher quality whey concentrates such as WPC 80?

Yes and no. Whey isolates are 90% pure protein, while higher quality whey concentrates will be ~80% pure protein, making isolates “superior” on a gram-for-gram basis. However, both forms of whey digest rapidly and help support muscle-building and recovery goals. At the end of the day, which one you choose really depends on your goals. If you need a protein that is lower in calories and free of fats, lactose, and cholesterol, go with an isolate. On the other hand, if you need a protein that is more calorie dense and fat-laden, which may be beneficial when weight gain is the goal, choose a high-quality whey concentrate. Just be sure the label makes clear that the whey concentrate being used is at least 80% pure protein.
