One of the reviewers here is correct about large producers packaging their whey isolates under a variety of different brand names, but I was only able to find a few hydrolyzed whey proteins offered from all the products currently available online (there are many). I only found a few similar to this one with the distinction of being hydrolyzed which is presumably easier to digest and contains the highest available percentage of protein. A 28 gram serving of this product contains 25 grams of protein or 90% protein by weight. I have been buying whey protein powder for more than 15 years and used all the popular brands. This is simply the best whey I have ever used and tastes different than any others I've known up till now. Zero fat and zero carbs per serving. I no longer use or recommend soy isolates and while I have found some good quality brown rice protein powders the taste is so unpleasant I would stick to whey.

Since I was recently new to this whey product, I always start by purchasing vanilla since that's usually the most difficult flavor to do well (in my experience). If I don't like the taste, vanilla is always good to have around for adding to fruit smoothies (a smoothie easily overwhelms any subtleties of an objectionable vanilla whey flavor). If I like the taste of their vanilla I'll serve it solo as well as in smoothies. Once I know I like the vanilla, chocolate is usually next. This vanilla is excellent as far as vanilla goes and I'll be ordering more flavors soon. I use a VitaMix to quickly and easily mix a tasty 12 ounce serving.

One trick I can pass along for making a delicious glass is to start with a 16 oz measuring cup.

I prefer non-GMO, organic, raw food type, plant based protein powders such as Garden of Life's Raw Protein Powder or Raw Meal, but I also like to mix it up with a high-quality whey protein powder such as Dymatize Nutrition's ISO 100. There are a lot of protein powders on the market and I know it can get confusing trying to pick a brand and type. If you are looking for a reputable brand with great quality without having to worry about the product being packed with fillers, then search no further ...Dymatize is legit! I recommend the Gourmet Chocolate for it's flavor ...and in the 5 pound container so you get the most bang for your buck. I looked all over the web and Amazon has the best prices that I could find so save yourself some time and just purchase it here. If you found this review helpful, please click the yes button below. Thanks!

Flavor Name: Gourmet VanillaSize: 1.6 Pound
I purchase this locally. My background includes casual weight-training and sports since I was very young, a degree in Physiology (thesis was on amino acid supplementation for muscle growth), a minor in Chemistry, and two years graduate work in Cardiovascular Physiology. I noticed a decrease in muscle mass while eating a non-bodybuilding, tasty, and healthy diet. Additionally, I have a slight sensitivity to drinking more than one cup of milk per day. After doing some casual research and deciding on this brand for hydrolyzed whey protein, I decided to add this to my diet. So far, I have been able to maintain higher muscle mass with this added to my normal dietary regimen. However, keep in mind that I am not muscle-bound, but athletic at 6', 185 lbs.

Flavor: I chose the Gourmet Vanilla flavor. Mixed with the recommended amount of water, it is subdued enough to not irritate, and sweet enough to take a little enjoyment. The sweetness is from the Sucrolose, so if you are staying away from Splenda and the like, this won't work for you.
ALSO VERY IMPORTANT*** don't let this sit around for more than a few hours after you mix it. I mixed a bottle and forgot about it for a day or two. It had the most putrid smell that was very hard to wash out of the bottle. Considering that most healthy foods I buy go bad fast (i.e. limited to no preservatives) I don't hold this against the product.

My personal mixes: I mix this in different forms to increase my daily protein consumption. I have no problems with it dissolving, even when just using a spoon to mix. The nutrional information lists 25 grams of protein per scoop (scooper included). As a comparison to protein rich foods: large egg - 6g, 8oz of chicken breast 8oz - 70g, 8oz of steak 65-75g.

Awesome protein for people trying to lose fatty weight but keep muscle tone. Just now finished up the powder & am going to order more. Does not give you protein farts or make your gut ache from the slow digestion process. Recovered from my Crossfit days better than when using other products. But not for bulking.

I am using ISO 100 for the last 2 years. Every time I was so happy with the taste. But this time I got it and I was surprised to see black worm like things in the powder. This will not dissolve in water. It's hardly 2-3 mm in length.

I hope Dymatize an Amazon will look into this matter.
