NOW Foods Whey Protein Isolate: User Review

NOW Foods makes a natural whey protein isolate in both flavored and unflavored varieties. Here's how this protein powder stacks up.

NOW Foods claims that their whey protein isolate is a high-quality protein supplement that is both bioavailable and easily digested. Here's my review of what seems to be a very good whey protein product. Learn more and decide for yourself.

NOW Whey Protein Isolate

Whey protein isolate is touted as being the ultimate of proteins. It is the most quickly digested, so when a quick boost in amino acids is needed, whey protein isolate is a great decision. Furthermore, as stated by NOW Foods, this isolate contains a high concentration of branched-chain amino acids in comparison to other forms of protein powders on the market.

This whey protein is a great choice for replenishing amino acids after a workout. When your body is depleted and needs protein to rebuild muscle tissue, a protein isolate is desirable.

However, at other times, when a slower digesting protein is desirable, an isolate would be of little use. For example, when you go to bed, you're essentially fasting for the entirety of your sleep. Therefore, at this time a slower digesting protein powder such as casein is better. Casein gives you amino acids over a longer time period.

In other words, at bedtime, the NOW whey isolate isn't a good choice. Although NOW's whey protein may have the highest biological value of any protein source, and whey is supposedly superior in essential amino acid content to beef, milk, casein, or soy, I always advocate choosing protein from whole foods over even the best brands of supplements any day.

Natural, unprocessed protein sources provide amino acids along with other important vitamins and minerals that are important for your health and raise the nutritional value. However, for reasons of convenience and at times when high protein and low carbohydrates and fats are desirable, I support the use of a whey protein powder.

This protein powder has a straightforward ingredient list with good quality ingredients. I'm glad to see that NOW Foods presents a compelling and honest claim of the effectiveness of the supplement. However, I do not agree with all their statements about what their whey protein can do. Therefore, in regards to the claims they make about their whey, I award NOW Foods whey protein isolate an 8/10.


This whey protein has a taste all its own. I would describe the taste as a pleasantly distinct vanilla flavor. I tasted the whey with orange juice, orange juice and fruit (half a banana and several strawberries), and in milk. The brand also offers chocolate and unflavored versions of the whey protein powder. The unflavored version is good for people who are looking for a more natural whey isolate choice. Unflavored is also good if you like to use whey as a baking ingredient and want something with a neutral flavor.

I was more than satisfied with all the whey protein blends. However, I wasn't particularly impressed with the taste. In other words, I've had better tasting proteins in the past but not many. Therefore, in regards to taste, I award their whey protein an 8/10.


I've supplemented with a variety of different protein powders. To date, I find that whey protein isolates often mix very well, whether you're just mixing the whey with water or blending it with other ingredients. This whey isolate product was no exception.

I found that the whey protein mixed in well every time with no protein sticking to the sides and being wasted. This isolate didn't appear to have a noticeable texture. I felt that it really mixed in well and left the texture of the blend uncorrupted. Therefore, in regards to mixability/texture, I award NOW Foods whey protein isolate a 9/10.

Overall Review

As I stated earlier, I'm a big fan of a compelling, yet honest, health claim. NOW Foods usually does a great job of presenting you with the truth, and the brand's whey protein is no different. Far too many times have I encountered supplement ads declaring ridiculous health claims that even steroids would struggle to meet.

It's refreshing to find a supplement company that offers good quality ingredients and realistic claims. I enjoyed the taste of the vanilla flavor most of all. However, in the past, I've tasted other protein powders which I found to be more desirable. But I was satisfied with the mixability/texture, as it was what I expected from a whey isolate.

One of the most important points to remember is the price of this whey protein. For 5 pounds it's only $60. That may not seem cheap, but there are 71 servings per container and each serving has 25 grams of protein, which is a high amount of protein per serving. Also, the protein is high quality, 100% whey protein isolate. So, this protein powder is actually a great value when you look at price per gram of whey protein.

Furthermore, you're still receiving a quality amino acid profile with this supplement (branched-chain amino acids as well as other essential amino acids). Therefore, when we consider this perspective, this NOW Foods product is a good decision economically and personally (taste, mixability/texture, and effectiveness). Therefore, for an overall review, I award NOW Foods whey protein isolate vanilla flavor an 8.5/10!
