For me , it is the best tasting & best ingredients of any Whey protein anywhere. Always has been. I have 2 protein shakes a day & it is exactly what my body needs. I would highly recommend it to everyone who wants all the good stuff for you & nothing bad.

It mixes well in a shaker or blender and I love adding it to my morning coffee. This brand of protein also has great ratings from cleanlabelproject.org and labdoor.com.

I choose this product that is clean of sugar and unatural sweeteners. The taste is actually awful at first, but becomes bearable after I have used it for a few weeks. I also added few drops of Stivia sweetener to improve taste. I think the company can improve the project by adding it to a Stivia sweetener.

Going through my 2nd 10lb right now and I'm really happy with it and the absence of extra additives!

Both the Van and Choc have a light flavor not a strong sweetness like most Wheys on the Mkt. Also, take note it's very clean in Macros. Beats all competitors when comparing Macros and serving size of the scoop.

After reading positive reviews on Labdoor.com, i thought i'd give this a try. It mixed well with water, but as others stated, it has that mild chalk taste. I can sacrifice taste for quality. I would buy again.

You can't beat the low calorie/low carb/low sugar/low cholesterol ratio to the protein content. Great product for the health conscious consumer.

Absolutely the worst protein I've ever tasted. Is it because it's so natural that it makes me want to throw up? The reason why I decided to try this product was because we're trying to conceive again and base on number of reviews. It all points to this product is the most natural and do not contain much junk and it was the only reason why I decided to give this protein a try. This is probably one of the worst protein I've ever tasted.

i purchased 2x5lb tubs, one unflavoured and one strawberry. it's a good protein which mixes well and doesnt contain crap. it's not overhyped which is great. we all know that over hype products sure are crap. this is basic quality whey isolate for a great price. by the way, people on review section complaining that it doesnt mix well must be shaking the thing like freaking grannies. i shake it proper and mixes well no problem. strawberry taste is very mild, i have seen better tasting whey powders but it smells good, only if it tasted a bit more stronger would be perfect. unflavoured is ok it basically tastes what whey is supposed to taste without flavour. people must understand that unflavoured whey doesnt mean no taste. it will taste like pure whey which reminds of milk flavour but stronger.

I have been purchasing the 10 pound bag of Dutch Chocolate for some time now and I love the product. I mix mine with low fat chocolate milk and it is great. I have seen some comments on how it doesn't mix well and I can say that I have not had this issue ever. It is a good protein that does not have a lot of added junk. If you want a simple protein isolate then this is a very good one.

I have tried many proteins. This has NO taste and I can mix it in many things verses having to buy different flavors and tiring of the taste befre the tub is empty. This is my 3rd tub of the protein and will continue to buy. Most important to me is it is a clean protein without fillers, sugars etc. I deffinently recommend NOW protein. FYI do not mix in water, hence water and powder equal chalk.

1) I know a nutraceuticals testing lab and an executive gave me the green light on the band for using high quality ingredients even though it seems to be a budget brand. 2) I lost body fat 0.5% while supplementing with this brand which I didn't see in the past year with other brands. I also gained 1.5lbs of lean body mass. 3) There's no artificial sweeteners, just erithritol/stevia which is a natural sweetener I trust. It's a light amount of sweetener just to give the protein it's light flavor. It makes it easy to stomach I'd I'm feeling lightly nauseous from an intense work out. 4) The cost per gram of protein is one of the lowest prices when buying 10lbs.

This is excellent protein powder. It is pure whey isolate which means no fat, no carbs, no sugar, just great protein. I use the natural unflavored, I use it for smoothies and it is EXCELLENT in smoothies, it was very little flavor and so takes on the flavor of whatever else is in the smoothie. By itself, this is DISGUSTING, it has an awful chalky taste that I can only describe as watered down reconstituted powered milk with an added sour tinge. If you are after a protein that is just protein and don't care what it tastes like, this is the protein you should be using, no additives, no preservatives, no sugar, no artificial colors, sweeteners or garbage.

I picked this because, out of all the protein powders, this one had the most protein (~36.8 grams of protein per dollar for the 10 lb natural unflavored one at the time of this review) for my money. I got the 1.2 lb tub, in case I didn't end up liking it. but I'm glad I took the risk and bought it. The stuff mixes well within seconds in water with a spoon; and tastes pretty good, especially with cinnamon & (NOW) creatine monohydrate. I'm glad I tried it, and will most definitely buy again, most likely the 10 lb bag of the unflavored as it's more cost effective. :) *EDIT* One HUGE caveat. Unless there was a mistake, the scooper they send you with it does not give you a serving (28g) of the powder, but 1.5 servings (~42g) of it, even when flat. Which would explain why I was going through the stuff faster than I originally thought. So I had to dock them from a 10/10 to a 5/10 because, again, unless that was an honest mistake, it was pretty shady of NOW Sports. Ironically, a scooper with another whey protein I saved for over 10 years actually does indeed give the correct amount of whey protein powder, so I'm using that one instead. Hence why it's always a good idea to weigh out your serving sizes on a digital scale just to be sure. EDIT 2: To be fair, the 10 lb bag does have a proper sized scoop (though I still prefer to weigh to be sure, as it seems to under weigh the amount needed), so I've decided to bump them back up to a 10/10.
