Protein powders are the worst.

They have the noobies believing that they can take a protein shake, and call it a day.

A couple of things are misunderstood when it comes to supplementation (especially pre workouts, see that buying guide as well) in general.

With a whole bunch of top 10 lists out there, this has to be one of the best ones you'll find.

It features different lists for people with specific preferences and / or dietary needs (like vegetarians, or halal & kosher friendly powders).

You can just skip to our final top 10 list or guide yourself through this buying guide to find the best protein powder for you.

Best Overall

​​Transparent Labs – the name says it all about this company and their commitment to open labeling and premium quality is never more clear than it is with ProteinSeries 100% Grass Fed Whey Protein Isolate.

If you compare this to their whey concentrate, this is a much cleaner product with less than 1 gram of sugar, 1 gram of carbs and zero fat.

Whey isolate has a higher protein content (90%) than concentrate and this product even has the flavoring and sweetener broken down into mgs.

To say that this is a great fit for the Paleo diet is a understatement!

Transparent Labs has made quite a name for themselves with their transparency and quality, which is great, but how does it taste?

While users tell us it tastes great, it does have only basic vanilla and chocolate flavorings.

It may be arguable as to whether or not whey is a true Paleo food – but you are getting an exceptionally pure product with excellent benefits.

As far as value, you’re getting 30 servings for a premium price, so again, you get what you pay for.

All in all, Transparent Labs ProteinSeries 100% Grass Fed Whey Protein Isolate is an exceptional product – we’d say it’s a great choice – one of the best choices, for anyone following the Paleo diet.

PROS

  • 30 Servings, 112 Calories, 28g Protein, 0g Sugar, 0g Carbs
  • High protein per serving (28 grams)
  • 112 calories, zero carbs / per serving
  • Free of artificial flavoring, preservervatives and hormones
  • Super clean and pure protein
  • Naturally sweetened with stevia
  • Stimulates muscle growth and enhances recovery

CONS

  • One flavor (chocolate)
  • Expensive (you get what you pay for high quality/ pure)

Best known for their C4 pre-workout, Cellucor has been making decent products for years.

They are not a brand that has switched to full disclosure labeling, seemingly content to be one of the more established brands still using prop blends in many of their formulas.

They don’t shy away from artificial ingredients either, even in their best formulas.

So it is with Cor Performance Whey.

The label is fully disclosed bt nowhere near full transparency with no breakdowns given for the “Whey Protein Matrix” of whey isolate and whey concentrate.

There’s 2 grams of sugar, 4 grams of total carbs and 1.5 grams of fat – fairly standard.

Cellucor does use artificial flavoring and sweeteners, so as you can see, there’s nothing that makes this product really stand out – but did we mention the flavors?

The one area this product really steps it up is flavoring – you’ve got the usuals, but you also have peanut butter marshmallow, chocolate chip cookie dough and cinnamon swirl – and yes, they do taste really good!

As far as value, you’ll get 70 servings in a 5 pounder at an average price, so it’s a solid value.

So, overall this is a decent product that only tries to be good, it’s not the best and it knows it.

PROS

  • ​This is a good value with 70 servings and an average price
  • Great flavors and the taste is excellent
  • Mixes well in in water or milk

CONS

  • Artificial ingredients
  • Just an average powder, there's nothing remarkable about it

Like yourself, I'm not surprised.

You've undoubtedly seen this as the number one recommended protein and rightfully so.

Optimum Nutrition has made it's mark in being the number 1 protein powder in the whey category.

The reason for that is because it contains super high quality protein sources (whey isolate, and lists it first in the protein)

And being one of the most popular whey protein powders, there's almost always deals on this supplement.

Whether it be clearences, BOGO's or whatever else you can imagine. 

It's also one of few protein powders that is lower in carbs and fats.

Every scoop has 24 grams of protein, 120 calories, 1 gram of fat (.5g of saturated fat) 3 grams of carbs (1g of sugar).

And of course, like any other protein powder, it has naturally occuring BCAA's (5.5g) and it also has 4 grams of glutamine ​to help with recovery and muscle growth.

So if you've got your multivitamins and creatine, then all you need is a protein powder like this one.​

PROS

  • Lists whey isolate first in the profile (high quality protein)
  • Lists whey isolate first in the profile (high quality protein)
  • Great value
  • Awesome recovery (gluta
  • ​Easy digestion
  • ​Low in calories, fats, and carbs
  • ​Addictive taste

CONS

  • ​(No cons really)

This protein hits the spot right from the title and to the moment you take your first sip.

Zero Carb Isopure is a no B.S. type of powder that uses absolutely no carbs and only whey protein isolate so you can digest it easily.

Although it's easily digestible, it might give you a bit of gas. ​

Building Muscle

D​ISO-100 is not only a low carb protein powder but is also very low in fat (half a gram per serving).

Dymatize's protein is affordable, so if you're on a budget but still need a whey protein isolate that is trusted and owned by a solid company, then ISO-100 is for you. ​

While Dymatize is not known for their other products, their protein powders are out of this world with flavoring and nutritional value.

ISO-100 uses hydrolyzed whey protein isolate for the fastest absorbing and lists whey protein isolate as the 2nd source. ​

It is mainly sweetened with natural flavors so it isn't as reliant on artificial flavoring as other supplements would be. ​

Most people seem to enjoy these flavors: Gourmet Berry, Pina Colada and vanilla.

ISO-100 keeps the flavor strong by relying mostly on stevia. 

PROS

  • ​Great whey isolate complex
  • ​Reasonably clean formula
  • ​Incredible flavors

CONS

  • ​They use artificial ingredients - why?
  • ​Expensive - 76 servings but the quality does not justify the price
