ALL ABOUT PROTEIN SUPPLEMENTS: CHOOSING THE BEST PROTEIN POWDER FOR YOU

Protein is the most important macronutrient when it comes to fat loss or muscle gain goals because, 

  • in order to build muscle, you have to consume sufficient amounts of protein

  • In order to lose fat and retain muscle while in a calorie deficit, you have to consume sufficient amounts of protein

Now in general I believe that supplements are pretty overrated, except for protein powder which CAN actually be very useful. 

Protein is one of the harder macronutrients to incorporate into our diet because it generally requires storage (meat and dairy need to be refrigerated) and prep time (meat, eggs, etc., have to be cooked well) and therefore it can be less convenient. 

However, protein powder is super convenient! You can mix it into oatmeal for some High Protein Overnight oats, you can use it to make High Protein Smoothies, or you can just mix it with water and drink it from a shaker bottle while you drive to work after the gym. It’s easy and I often recommend it to my clients who struggle to get enough protein from their food. 

However, there are A LOT of different types and brands of protein powder out there, and it can be confusing to know which protein powder you should buy, especially if you go into a GNC and ask the worker behind the counter what you should get. (I worked at a GNC for a few years after high school and I was that worker who gave bad advice back then. Sorry!) 

I am going to list my favorite protein powders, but first I want to give you tools that you can use to pick a good protein powder from the options that are available to you.


As coaches, we believe in giving our clients the tools for them to feel as comfortable and confident as possible in their nutrition as possible.

Before I suggest some of our favorite protein supplements, let’s talk through how we can identify a good option!

how to choose A PROTEIN POWDER

1 || MAKE SURE THAT MOST OF THE CALORIES COME FROM PROTEIN

Example: check out the nutrition label of this unnamed protein product listed below.

The majority of the calories from this protein powder come from carbs and fats. 

9x4.5 + 15x4 = 100.5 cals from carbs and fat
21x4 = 84 cals from protein

This makes it more of a “meal replacement” shake rather than a way to supplement protein intake. If you are drinking a protein shake to increase your protein intake, try to make sure it is primarily protein. 

2 || CHECK THE SOURCE OF THE PROTEIN

Most proteins are made from milk derivatives, with whey protein being the most popular source. This is important because if you are a vegan or allergic to milk, you probably don’t want to consume a milk product!

In order to see if a protein powder is made from milk products, look at the ingredients on the nutrition label. 

For example, look at the label of the protein powder below.

Any quality product will list something like “Contains: Milk”  under their ingredients. 

Most protein powders are made from milk because milk is readily available and it's a really good source of protein, so again this tip is more for individuals who have a milk allergy or who don’t want to consume animal products. 

For those who don’t consume milk products, there are great options with pea protein, egg white protein, hemp protein, and more.

For everybody else, milk protein is a great choice.

3 || MAKE SURE THE PROTEIN POWDER IS TESTED BY A THIRD PARTY. 

Supplements are not overseen by the FDA or any other governmental agency and are therefore an unregulated industry, meaning supplement companies do not have to go through any sort of process in order to ensure that their nutrition labels are accurate. They can more or less put whatever they want on their label (with the exception of some specific health claims). 

That means if you want to know whether or not the nutrition facts of a protein powder are accurate, you have to look for supplement companies that go through the trouble of independently verifying their products through a third party. 

The third party that I trust the most is called NSF Certified for Sport, and it is the company that many athletic organizations (major organizations like the MLB) use to verify products that their athletes can safely use. 

Conveniently, they have a website where you can peruse the list of their certified product companies

NO NEED TO BE OVERWHELMED

Some people (usually somebody who is trying to sell a specific protein powder) will make buying the right protein powder WAY more complicated than it needs to be. They’ll talk about different types of protein compounds, bioavailability, amino acid profile, digestibility, and other technical terms in order to make it sound like all other products are trash and you HAVE to buy their product. You don’t. Keep the three tools from above in mind if you want to pick your own protein powder. 

Now don’t ever let the salesman at GNC bully you into buying the latest and most expensive protein powder ever again!

And if you don’t want to go through the trouble of picking your own protein powder, here are my favorite widely available protein powders. 

SOME OF OUR FAVORITES:

Optimum Nutrition Gold Standard 100% Whey

Favorite whey protein. Optimum Nutrition has been around forever. Their protein mixes well, digests well, tastes good, and is available pretty much everywhere. You can even pick up a bag for a good price at Costco. Oh, and they’re NSF certified!

Honorable mention: Dymatize is another brand that has been around for a long time, tastes good, is widely available, and is third-party tested by Informed Choice

Muscle milk Pro Series

Favorite grab-and-go protein. Muscle milk is another company that has been around for a long time, they are NSF certified, and you can find their ready-to-drink protein shakes in most gas stations. 

Honorable mention: Fairlife Core Power and Premier Protein are two other brands that make ready-to-drink protein shakes that are widely available and taste pretty good. However, they aren’t as clear about their third-party testing status, which is why they’re only on the honorable mention list. 

Vega Sport Premium Protein

Favorite vegan protein powder. Vega is another company that is NSF certified and they make a vegan protein powder where the vast majority of calories come from protein, not carbs or fat. The only con here is that Vega is on the expensive side per serving.

Promix Vegan Protein Powder

Another great vegan option. Promix is also NSF certified, the majority of its calories come from protein, and their protein is a little bit cheaper than Vega. 

Honorable mention: Sunwarrior is another vegan protein powder that is fairly priced, contains mostly protein, and is third-party tested.

WHAT ABOUT COLLAGEN PROTEIN?

Collagen protein can be a polarizing topic and that is because collagen is not a complete protein source, meaning it doesn’t supply all of the essential amino acids (EAAs) that our bodies need. 

For this reason, we usually recommend other protein sources to our clients over collagen. 

However, this doesn’t mean that collagen protein is useless! If you are eating enough protein from multiple sources throughout the day, odds are pretty good that you’re getting all of the EAAs that you need, even if 10-20 grams are coming from collagen.  

So if you like adding unflavored collagen to your coffee or oatmeal for an extra protein boost, feel free to keep doing it.
