 Mixability  5 Star Rating

This protein powder is made completely of whey isolate, which means that it will be incredibly easy to mix; in fact you will not have any problems mixing this with just a spoon and a sufficient amount of liquid.

 Taste  4.5 Star Rating

The taste of this product largely depends on the flavor chosen. Based on the creamy vanilla and Dutch chocolate flavors this product tastes great. However if you choose flavors such as Natural chocolate the taste will be much less sweet and more bitter. A great option if you are looking to avoid artificial sweeteners is to get the unflavored version and add it to something you like the taste of such as almond milk or something similar.

When to use

Specific times

Whey isolate digests incredibly fast, so to take advantage of this aspect the best time to take this protein powder is first thing in the morning when the body is staving and also immediately following a gym workout when the body is looking to repair damaged muscles.

General times

Whey isolate can also be taken at just about any time of the day; it can be great to use when time is tight, or as a complement to a meal that does not contain enough protein.

When to use a different type of protein

Although whey protein can be taken anytime, there are some times of the day that casein protein would be better; for instance right before bed or when you know that you will be going without food for a considerable amount of time. This is because casein protein takes up to 8 hours to fully digest which will give your body a continuous supply of protein to use.

Overall Score: 100% - Excellent

One of the purest protein powders on the market!

My goals in life revolve around staying lean, while having enough muscle to not look like a skeleton. I’ve been looking for a protein powder for a while now that doesn’t have carbohydrates in it (which is harder than you may think) I finally ran across this product and I love it! I got the unflavored taste so that I could mix it with my smoothies and add it to other drinks that I enjoy!

Flavor/Taste: 5 Star Rating
I love the unflavored taste since I can mix it into anything I want without it adding an extra weird flavor to my drink.

Cost/Value: 5 Star Rating
Without a doubt the cost of this product is very inexpensive when you compare the quality of this product to others. Even optimum nutrition has whey concentrate in it which costs less to manufacture, yet Isopure is just about the same cost per pound.

Mixability: 5 Star Rating
Extremely easy to mix into anything I want; this protein powder even mixes into cold drinks from the refrigerator. I usually add this to my cashew milk.

Effectiveness: 5 Star Rating
I’m not really sure what kind of results I’m getting from this product, but I really do believe that this is the best protein powder for me since it contains lots of vitamins and minerals and has zero carbohydrates, which so far for me being on a low carb diet has really helped me to keep the weight off.

Overall/Conclusion: 5 Star Rating
Overall I think is product is a terrific value; it mixes super easy and really is the purest protein I have come across. There is no whey concentrate or any added artificial sweeteners (if you get the unflavored version) and the extra vitamins and minerals really an added benefit since I’m not currently taking a multi-vitamin. I would definitely recommend this product to others who are looking for a high quality protein powder and I plan on continuing to buy this product.
