The Grass Fed Whey Isolate from Opportuniteas is our pick for the best protein powder for CrossFit overall. Since the unflavored version is made of only two ingredients, grass fed whey isolate and non-GMO sunflower lecithin as an emulsifier, it ticks our boxes for a high quality protein supplement. It has no additives, no soy, no artificial sweeteners or flavors, and the ingredients are top notch. In fact, it is so good that it won our top pick for the best protein powder for diabetics.

You can mix this powder in an unflavored shake, add it to your coffee, or even add it to different recipes. Being unflavored, it will not change the taste of your food.

However, if you want a flavored protein powder, you can get the Opportuniteas in three different flavors: chocolate, vanilla, and coffee. The coffee flavor is our favorite, because it is obtained by adding coffee extract to the base ingredients of whey isolate and sunflower lecithin.

The chocolate and vanilla flavors are delicious. However, they are sweetened with organic cane sugar. Even though organic, some people may not want sugar in their protein shake. Even so, regardless of your needs, Opportuniteas will be able to satisfy them through one of the available flavors.

Pros

  • Very high protein content
  • Has variety of flavors
  • Base recipe includes only two quality ingredients

Cons

  • Can be expensive for a protein powder, even though makes up for it through quality

BulkSupplements offers one of the best deals on the market for protein powders for CrossFit.

You can mix this powder in an unflavored shake, add it to your coffee, or even add it to different recipes. Being unflavored, it will not change the taste of your food.

And the best part? Just because this supplement doesn't break your bank account, it doesn't mean that it is low quality. BulkSupplements has been known for offering high quality supplements at very affordable prices. And they can only do that because they sell in all kinds of different sizes - from 1-pound packages, to a whopping 44-pound (20kg) bag!

This protein isolate contains 90% protein per calorie and has only two ingredients: whey protein isolate and soy lecithin. The last part may scare a few people. However, soy lecithin, which is an emulsifier, is different from the soy protein, which has the effeminating effects in men.

Flavor-wise, you can only get this powder unflavored. Therefore, unless you like neutral taste shakes, we recommend you to have a few smoothie recipes on hand. For our favorite recipe, add this powder to a blender along with some milk or milk substitute, a banana, two teaspoons of peanut butter, and a dash of cacao powder for a chocolate, banana, peanut butter smoothie.

Pros

  • Very good value for money
  • Has only a couple of ingredients
  • Can be bought in very big quantities

Cons

  • No flavored options

We believe that the Dymatize ISO 100 is the best post-workout protein powder for CrossFit. The reason for this is very simple: Dymatize is a hydrolysate whey protein powder, which is a type of protein supplement that is digested and absorbed by your body very quickly. Thanks to this property, the protein in the Dymatize will fuel your muscles faster than with any other supplement.

Aside from its absorption efficiency, we also loved the variety of flavors you can choose from. Ranging from vanilla to fudge brownie or birthday cake, you can get this powder in 11 delicious different flavors.

However, you should know that sucralose is one of the sweeteners, with the other being stevia. Even though we are not taking a stance on how healthy or unhealthy artificial sweeteners are, until there are more studies available, some people want to avoid them. For this reason, we will point out sucralose's presence in this hydrolysate protein powder.

Pros

  • Delicious
  • Very fast absorption
  • Big variety of flavors

Cons

  • Has sucralose as one of the sweeteners

For CrossFit athletes who want a vegan protein powder, we recommend Truvani. This supplement is our pick for the best vegan protein powder for CrossFit, thanks to its all-natural ingredients and protein blend from multiple sources.

When thinking about vegan protein powder, most people believe that it is not a complete protein ready to fulfill their training needs. However, with Truvani you get protein from pea, chia seeds, and pumpkin seeds, which meets the essential amino acid profile required to be considered a complete protein.

But what about the taste and ingredients? Truvani is available in four different flavors - banana cinnamon, chocolate, chocolate peanut butter, and vanilla - which are all naturally sweetened with monk fruit and flavored with natural and organic ingredients. Additionally, Truvani prides itself on not having any additives, fillers, or preservatives, but having all ingredients hand selected to ensure quality.

Regardless of whether you are vegan yourself, or you just want to try something else for a change, you can't go wrong with the plant-based protein powder from Truvani.

Pros

  • Complete source of protein
  • Organic ingredients
  • No fillers, additives, preservatives
  • Variety of flavors

Cons

  • Some may find the taste too sweet

If you are looking for the best casein protein for CrossFit, then the Legion Casein+ may be the ideal choice for you. What we liked the most about it is its protein to calorie ratio, which is one of the few sub-100 calorie powders you will find. This makes it a good choice for anyone who wants a protein powder for weight loss and muscle building alike.

The Legion Casein+ is made of a few ingredients, each easier to pronounce than the previous one. Moreover, it is gluten-free, soy-free, non-GMO, doesn't have fillers, additives, or artificial ingredients, and is sourced from hormone-free bovine. This is what we call quality.

In terms of flavor, you have four different choices: milk chocolate, strawberry, vanilla, and banana cream pie, all of them sweetened with stevia leaf extract. Regardless of your preference, there is something for everyone.

Lastly, we should note that we were not impressed with its mixability. For this reason, we recommend you to mix the Casein+ using a blender. If you try doing it with a spoon or a shaker bottle, the powder will not dissolve completely and you will get a few clumps.

Pros

  • Very good protein to calorie ratio
  • Naturally sweetened
  • Variety of flavor

Cons

  • Doesn't mix well without a blender

We like the egg white protein powder from Now Sports because it contains only one ingredient: powdered egg whites. For this reason, we believe that it is one of the best protein powders for CrossFit; it has no additives, no artificial sweeteners and flavoring, and no soy or gluten.

You can only get this product in an unflavored state. For this reason, we recommend you to mix it with fruit for a smoothie, add it to your coffee, or add it to different recipes because it will not change their taste. Additionally, you can use this protein powder for baking.

However, the mixability is not great. If you try to mix it with a spoon, it will turn into a gooey clump which is not appealing to say the least. For this reason, we recommend you to use a blender or a shaker cup and give it a brisk shake.

Pros

  • Made of only one ingredient: powdered egg whites
  • Can be used in different recipes without altering the taste
  • A good alternative to whey protein

Cons

  • Gets clumpy if mixed with a spoon

How to choose the best protein powder for CrossFit?

Glass of a protein shake with a spoon full of powder next to it

Choosing the best protein powder for crossfit looks a lot like choosing the best powder overall. There are some thing you should consider before purchasing, and these are:

  • Artificial sweeteners
  • Added sugar
  • Proprietary blends
  • Additives
  • Protein per calorie

Artificial sweeteners

Artificial sweeteners are sugar substitutes that provide a sweet taste without containing nearly as many calories as sugar. In the amounts used to sweeten protein powders, they are basically zero calories.

Artificial sweeteners are chemically made and can pose a health risk, but more research has to be conducted to make a solid correlation.

Either way, these are the top most used artificial sweeteners, and the brand they are marketed under:

  • Aspartame - NutraSweet, Equal, Sugar Twin
  • Acesulfame potassium - Sunnet, Sweet One
  • Saccharin - Sweet'N Low, Sweet Twin, Necta Sweet
  • Sucralose - Splenda

If you still want a low-calorie flavored protein powder, without sugar, consider products which have been sweetened with the following natural sweeteners:

  • Stevia
  • Erythritol
  • Xylitol
  • Yacon syrup
  • Luo Han Guo or monk fruit

If you want a reliable list of protein supplements with no artificial sweeteners, we recommend you to check our article on the best protein powder without artificial sweeteners.

Added sugar

Another thing we recommend you to be on the lookout for is added sugar.

In the quantities present in protein powder, sugar is not necessarily harmful - unless you suffer from a condition like diabetes. However, the drawback is that sugar adds a lot of unnecessary calories to your supplement.

You may find sugar listed in the ingredients list as:

  • Sugar
  • Coconut sugar
  • Cane sugar
  • Corn syrup
  • Glucose syrup

These are the most common. Usually, if it has the word "sugar" or "syrup" in its name, then you know it is added sugar, whether it is organic or not.

As a caveat, you should know that coconut sugar is healthier than regular sugar.

And also, you should know that natural sweeteners are a better choice, because they don't have as many calories. So it's all a matter of goals, at the end of the day.

If you are a crossfit athlete, whether you choose a protein powder with sugar or not is up to you. We believe that doing so is not inherently wrong, due to the small amount of sugar per serving, if you have the calories for it.

Proprietary blends

Proprietary blends is a popular term used by supplement companies to market their products.

The term is used to describe a blend of ingredients which are then listed one by one. However, the amount in which each ingredient is present in the product is not mentioned.

Proprietary blends can be listed as:

  • Proprietary blends (d'uh)
  • Blend
  • Complex
  • Matrix
  • Proprietary formula

There are a few issues with these blends though.

First of all, it sounds fancy, so the company may charge you more just for this reason alone.

Secondly, the FDA doesn't require specifics with blends, therefore it's easy to hide what's in the formula. Since there are no restrictions by the FDA as to the specific quantity of each ingredient when it's labeled as a blend, why should the manufacturer bother?

Which leads us to the third point.

It is easy to cut on costs. Since you don't know the exact amount of each ingredient, you don't know whether the formula is effective or not However, the manufacturer can easily dilute the active compounds in the blends to cut production costs.

Additives

Lots of protein powder manufacturers use certain additives to improve their products.

For instance, some people don't want to read "soy" on their ingredient labels. However, some protein powders use soy lecithin as an emulsifier, for better mixability. Soy lecithin was proven to not have any harmful effects like soy protein, so it is a safe ingredient unless you are very sensitive or allergic to soy.

However, if you want to avoid soy lecithin, you can choose protein powders made with sunflower lecithin.

Another common additive is represented by gums.

The most common one is xanthan gum, which can cause stomach problems, which is an issue especially for people who have undergone weight loss surgery. If you are in this category of people or want a protein powder safe for your stomach, check our article on the best protein powder for gastric sleeve patients.

Protein per calorie

Before getting your protein powder for CrossFit, you should look at how many calories you consume with that protein powder or shake, and how much protein you are getting from those calories.

A gram of protein has 4 calories.

Therefore, the more protein you get for the less calories, the more concentrated your protein powder will be - and, supposing it has all the essential amino acids, the better.

Therefore, we recommend you to look for protein supplements that meet the following criteria:

  • At least 20g of protein per 30g of powder
  • Ideally 100-150 calories per 30g of powder

If you get a low number of protein and high number of calories, it must mean that the powder is packed with carbohydrates and/or fats. The idea behind a protein powder is to get your protein, not your carbohydrates or fats.

Types of protein powders

In this section of the article, we will talk about our favorite types of protein powder you should look for. These are:

  • Whey protein
  • Casein protein
  • Egg white protein
  • Plant-based protein

Whey protein

Whey is the most common and also popular protein supplement on the market. It is a source of protein naturally found in milk. When mixed with a complex combination of enzymes, rennant, the milk splits into whey and curdles used for cheese and casein powder.

The whey, in its liquid form, is then pasteurized and dried to the protein powder we all love.

From there on, through different filtration methods, the powdered whey is further processed to isolate the protein in as much quantity as possible, while getting rid of some of the fats and lactose naturally found in milk.

After filtration, there are two types of whey protein:

  • Concentrate
  • Isolate

There is actually a third - hydrolysed. According to this study, aside from some minor fat burning benefits, it is as effective as isolate whey protein. However, it is considerably more expensive.

So let's look at the differences between the two biggest players.

Whey concentrate

Whey concentrate is obtained from whey through a process called microfiltration. This is usually the less expensive type of whey protein powder and has the following characteristics:

  • 80% protein by weight
  • 20% milk sugars, fats, and flavoring

The whey concentrate is ideal for those who want a good protein powder without spending much money on it.

However, people with lactose intolerance should stay away from it.

Whey isolate

Whey isolate is obtained by further processing the whey concentrate, through processes like ion exchange and ultrafiltration. This type of powder is usually more expensive than its concentrate counterpart and has the following characteristics:

  • 90%+ protein by weight
  • 10% fats and flavoring

The two filtration methods get rid of most, if not all of the lactose.

Therefore, whey isolate is a better choice for people who want a higher protein content by weight or who suffer from lactose intolerance.

However, you should keep in mind that it's usually more expensive than the concentrate.

Casein protein

Casein protein is the little brother to the more famous whey protein. Even so, casein has gotten its fair share of love from fitness enthusiasts, mainly because it digests slower, making it a great choice for a protein shake before going to bed.

As discussed above, after using a mix of complex enzymes, the milk splits into liquid whey - used for whey protein powder - and curdles. The curdles themselves are the casein.

Casein has the unique capability of curdling inside the stomach.

For this reason, it stays in the stomach much longer than whey protein, releasing a slow dose of protein in your bloodstream for up to eight hours.

Casein also has anti catabolic effects. For this reason it is believed that it is best taken before bed, because most of the muscle we lose from "starvation" happens during our sleep. However, no study was conducted to prove that ingesting casein before bed can prevent muscle loss better than other protein supplements, nor is the catabolic issue big if you are doing any sort of resistance training on a regular basis.

Quite the mouthful.

So let's see the characteristics of casein protein:

  • ~75% protein by weight
  • Releases slowly in the bloodstream
  • Keeps you full for a longer period of time than other types of protein powder

Egg white protein

Another popular contender to whey protein and casein is the egg white protein powder. This supplement is obtained through pasteurizing and dehydrating the egg whites so you are left with powdered egg whites.

As far as efficiency is concerned, egg whites protein powder is very close to whey protein. So close, in fact, that the difference is not noticeable.

Egg whites protein powder is ideal for strict diets like the paleo diet, and for people suffering from lactose intolerance.

  • 80%+ protein by weight
  • Ideal for stricter diets

Plant based protein

Plant-based protein has a pretty bad reputation because most vegan protein supplements are not complete protein sources. This means that they don't have all the 9 essential amino acids - amino acids which our bodies can't produce.

However, this was an issue only when vegan protein powders appeared first on the market.

Nowadays, you can purchase plant-based protein powder blends, which are a combination of multiple sources of protein. By mixing protein coming from different sources, manufacturers can create a complete amino acid profile, making the powder a complete source of protein.

For this reason, we don't recommend purchasing vegan protein powder coming from only one source like pea, rice, or hemp.

How should CrossFit athletes dose their protein powder?

Pictture of a woman preparing a protein shake

Now that you found your best protein powder for CrossFit, you want to know how you should be taking it. That boils down to how much powder to take and how to time its consumption.

How much protein should you consume?

Numerous studies have been conducted in this area. Two of the most reliable studies that we have found - out of which one is a meta-analysis, a study of studies if you will - have shown that…

  • If you want to build muscle you should be consuming 0.73 to 1.1g of protein per pound of body weight, or 1.6 to 2.4g of protein per kilogram of body weight.

This is, of course, supposing you are doing some form of resistance training, like Crossfit.

  • However, if you want to lose weight, you should be consuming 0.36 to 0.76g of protein per pound of body weight, or 0.8 to 1.6g of protein per kilogram of body weight.

You should know that losing weight is a matter of burning more calories than you ingest, so it doesn't boil down to protein. These values are just recommendations to keep yourself healthy during a weight loss period.

The studies which suggest what you have just read can be found here and here.

When should you take your protein powder?

Just as with the intake, timing has also been intensely studied. Here is what scientists have discovered about protein intake timing:

The keyword here is "optimize". Good protein intake timing can certainly have benefits.

However, this is not as important as taking all your protein for the day. So if you can only get your protein shake two hours post workout, do that instead of skipping it altogether.

  • If you want to lose weight, you will still get your protein supplement right after the workout. However, if you are not working out, then you should get your powder in between meals. This will keep you satiated and curb your cravings.

Having a protein shake in between meals is a way better choice than most snacks out there. Unless your snack is a protein bar, though you have to pay attention to the calories in those too!

Our verdict

As you can see, choosing the best protein powder for CrossFit boils down to choosing a supplement that has minimal ingredients, comes from a complete source of protein, and that has as little additives as possible.

For this reason, we believe that the Opportuniteas Grass Fed Whey is the best choice.

Its protein content per serving is very high, has no additives, sugars, or artificial sweeteners, and is made of only a couple high quality ingredients.

However, if you feel like there is a better option for you in the list above, then we recommend you to go with that one. You can be confident that we have done the research for you and you will be getting one of the best products to help your performance.

Over to you.
