Love it

Posted by 5084888899779868919 on Aug 21, 2014

I was very happy to see that you have this product. I recently suffered a broken jaw and needed protein in my smoothies to not loose weight and heal. I have tried many and most of them make me sick, however, this certain brand does not. I love it, I can't taste it and it doesn't make my drinks gritty or so thick that I can't drink them. I am very pleased to have found it on this site. Thank you

If you're looking for whey protein without additives, this is a good choice!

Posted by 5727043718748149541 on Apr 27, 2014

I like this product a lot since it didn't have added sweetners nor lists preservatives. It was unflavored and yet didn't taste bad when mixed with yogurt or a pureed banana. I used it most often in shakes with fruit and I didn't think it needed more flavor. Enjoy this product and it's benefits! :) It's GMO and antibiotic free! :)

Best value natural protein

Posted by Reviewer2225835 on Mar 31, 2014

I have ordered this product a lot over the past year. Our family use it to make smoothies using a mixture of berries, cacao, coconut etc. It seems to be the best value source of non-denatured, hormone-free whey protein. The taste is okay, obviously non-flavored whey isn't something you'd generally regard as delicious, but when mixed with a few different things it does the job well! The only bad thing is that the recent $7 price increase per tub adds quite a bit to my monthly iherb bills! 4/5

pure whey

Posted by marianF on Feb 14, 2014

Finally, a whey powder that ticks all my boxes:Just pure whey concetrate, completely free of additives, sweeteners and flavors, non-GMO, growth-hormone free, mixes easily and on top of all that tastes really good, like milk powder, as it is supposed to.Very reasonably priced, I will buy it again and again and again...

Great source of protein.

Posted by 4989503481789022451 on Feb 12, 2014

I have been using the product for about 3 weeks in my daily protein shake. I combine this with frozen strawberries,blueberries,mango and water. The protein powder makes the shake very creamy and even though it is unflavored it imparts a very pleasing taste. This is the best whey protein powder I have ever used.
