Highest Rated Protein Powders. These 5 Brands Are Best

highest rated protein powders: Tub and Scoop of Chocolate Whey Protein Powder
My Favorite Chocolate Whey Protein Powder

You are probably wondering where can you find the highest rated protein powders?

Protein powders are everywhere these days. If you have been using them for a long time like I have, you have seen the prices increase every year.

Every product you look at says it is the best, so how do you know what you are actually getting for your hard earned money?

How much should you pay for a good quality protein?

You will pay anywhere from 43 cents to $1.00 per serving for the good stuff, maybe $1.00 to $1.72 per serving for the GREAT stuff.

I recently discovered a company that is not very well known because they do not advertise as aggressively as most of the bigger, more expensive brands. You won’t find this brand on the shelves of your local health food store either. as far as I can tell, they only sell on the internet, and this is one reason they are so much less expensive, yet have a top quality product.

Check them out at  MyProtein.com powders, and you will save a boatload. Their prices are extremely aggressive.

I will usually wait for a sale or promotion (they have a 35% or 40% off promotion going on almost all the time) when I buy protein, and then buy 6-10 pounds at a time to get the best deal.

How do you know if you are getting a good deal on the highest rated protein powders?

One way to know is to look at how many grams of actual protein you are getting in each serving. This will reveal the purity of protein in your particular brand.

In this article I am only looking at the purity, or percentage of actual protein.

Purity is simple to calculate, just divide the grams of protein per serving by the serving size to get your purity percentage.

For example, if your protein shows a serving to be 31 grams, and the protein per serving is 24 grams, 24 divided by 31 equals .77, or 77% protein. The remaining 23% is going to be sweeteners, flavorings and other ingredients. Needless to say, the higher the percentage, the more protein you are getting for your money.

My research shows that the quality of proteins can vary from as low as 69% to as high as 90% pure!

I looked at several dozen of the most popular protein powders sold on Bodybuilding.com (they pretty much carry every brand there is, and at very competitive prices) and it was pretty hard to find protein powders that were more than 80% pure.

The majority of the best sellers came in between 70-80% pure.

Here is a list of the highest rated protein powders that are at least 80% protein

These are ranked by purity from some of the biggest names in supplements. Purity calculations unless otherwise noted are based on Vanilla flavor. (The purity percentage will sometimes be very slightly
different on other flavors, and the variance is typically a couple percentage points.)

The 5 highest rated protein powders:


Purity 90% protein.

Allmax Isoflex whey protein isolate

 This came in with the best purity score. 90% is hard to find! ALLMAX has several protein powders but Isoflex is the purest, made of only ion and ultra filtered whey protein isolate.

  • The best quality protein I could find.
  • Available 1,2 and 5 lbs.
  • 10 delicious flavors
  • Cost: 5 lbs $1.17 cents per serving.

#2. Highest rated protein powders: MyProtein IMPACT WHEY ISOLATE 

Purity 84% (unflavored)

Impact Whey Protein Isolate

MyProtein is a company that makes a large variety of protein powders. Known for high quality and low pricing, this Isolate came in second with 84% pure protein content.

  • Available in 2.2lbs, 5.5 lbs and 11 lbs.
  • Grass-fed whey
  • Cost: 11 lbs 48 cents per serving. (outstanding price!)
  • Coupons and sale pricing available.

#3. Highest rated protein powders: Dymatize ISO 100 Whey Isolate  

Purity 83%

Dymatize ISO 100 Whey Protein Isolate

The highest performer in the Dymatize lineup, the main ingredient in ISO 100 is hydrolyzed Whey protein isolate. I have used this powder and the chocolate flavor is fantastic. ISO 100 is also available in 11 other indulgent flavors.

  • Only 1 g sugar per serving
  • Cost: 5 lbs 99 cents per serving.

Available in 1.6, 3 and 5 lbs.

#4.Highest rated protein powders: Natures Best Zero Carb Isopure  

Purity 81%

Natures Best Isopure Protein

Natures Best Isopure Zero Carb protein has been around for a long time, and they were one of the first companies to produce a clear protein powder (when mixed with water). One of the reasons the purity is a little lower than other protein is because is is loaded with vitamins and minerals. This is not a bad thing, but personally, I want my protein powder to be, well, protein powder!

  • Lots of flavors
  • Available in 1,3,5 and 7.5 lbs
  • Cost: 7.5 lbs $1.72 per serving. (pretty steep)

#5.Highest rated protein powders: MyProtein IMPACT WHEY PROTEIN 

Purity 80% (unflavored)

Impact Whey Protein

Another fine product at less cost than it’s Isolate version. This of course translates to lower purity. Probably the best protein for the money if you are on a budget.

  • Available in 2.2 lbs, 5.5 lbs and 11 lbs.
  • Grass-fed whey
  • Cost: 11 lbs 43 cents per serving. (Great deal!)

  1. Hi there,
    Thank you for a great article. I’m on the way of restarting my training program and was thinking of taking whey protein. After reading your article I was thinking of going with BPI Sports Best Protein.
    Are they age related as I’m just over 50. Do you have any other product to suggest?
    Thank you again for a great article. A lot of useful information.

    • Babacar,

      Thanks for your comment! I am also just over 50. BPI is a good choice as it is affordable and a very reputable company. I have used that protein powder myself a few times. Protein powders are not age related. I currently have a protein shake each morning, each night and immediately after every workout. I get very good results this way. I also recommend Optimum nutrition gold Standard which is also mentioned in the article.

  2. Awesome article post on protein powders, I must admit the highest purest protein powders are brand new to me.

    Are any of these good for someone who has allergies to milk and dairy products, I have trouble finding protein powders I can consume without problems due to the whey in them?

    I heard pea protein is a low allergy protein powder source, but is it a high rated protein powder worth investing my money into ?

    • Jeffrey,

      Thanks for the comment! Pea protein is an excellent choice for someone with dairy sensitivities. It will not have purity levels as high as whey, but it can be a valuable source of high quality protein and definitely worth the money. I will be publishing an article soon dealing with protein powders from plant sources.

  3. I am not that much into body building but I think a lot of the supplements used in the bodybuilding process can add to just good old fashion healthy body. I think these products that are high in protein can keep the body in top shape.I also believe that having an all around healthy body builds up your immune system and helps ward off a lot of infections we are prone to come down with, like the flu bug that is going around now. I try to keep in good shape and take daily vitamins but think I might just slip in some of these high protein powders. Can’t hurt. Thanks for the tips that your website provides for keeping in shape and also the cost of doing so. Your website is a very informative read.

    • Thanks for the comment. I agree that protein can be used fo general health as well as muscle building. Everyone needs protein to maintain healthy tissue!
