Best whey protein powder

Momentous Essential Grass-Fed Whey Protein

• Price: $$$$
• Flavors: Vanilla, Chocolate

Why we chose it

Momentous Essential is our pick for the best whey protein powder thanks to its high quality ingredients and rigorous quality testing.

Specifically, the powder contains whey isolate sourced from milk produced by grass-fed cows.

Whey isolate contains more than 90% protein by weight and is relatively low in lactose, whereas whey concentrate contains 25–89% protein and more lactose (2).

The powder also includes an enzyme blend that the company claims helps improve the absorption of protein and reduce stomach upset, though research doesn’t currently support these claims (3).

Momentous Protein is third-party tested and is both NSF Certified for Sport and Informed Sport Certified, which means it’s a good option for competitive athletes. It’s also certified gluten-free.

• Calories: 100
• Carbs: 3 g
• Added sugars: 0 g
• Protein: 20 g

Best unflavored whey protein

Naked Whey

• Price: $$$
• Flavors: Unflavored

Why we chose it

While some people enjoy flavored protein powders, others prefer unflavored ones that can be added to foods and beverages without imparting a taste.

Naked Whey fits this bill perfectly with its single ingredient — whey protein concentrate.

This protein powder is sourced from Rumiano Cheese, a California-based company whose products come from cows that have been pastured more than 300 days per year and more than 19 hours per day.

In addition, Naked Whey is third-party tested by Informed Choice.

If you prefer a flavored option, Naked Nutrition also offers Chocolate and Vanilla products, which are naturally flavored with coconut sugar.

Nutrition facts per 2 scoops (30 g) of Unflavored Naked Whey protein powder (5):

• Calories: 120
• Carbs: 3 g
• Added sugars: 0 g
• Protein: 25 g

Best casein protein powder

Ascent Native Fuel Micellar Casein

• Price: $$$
• Flavors: Vanilla, Chocolate, Chocolate Peanut Butter

Why we chose it

Ascent Native Fuel Micellar Casein is a high quality protein powder that claims to use only natural ingredients.

Casein is another protein that’s found in milk. Compared to whey, casein is digested more slowly. As a result, some people take casein supplements before bed for sustained protein digestion throughout the night (1, 6).

Notably, Ascent processes grade A milk in the company’s own facilities to turn it into protein powder, whereas most manufacturers buy preprocessed protein.

In addition, the product is third-party tested by Informed Sport to ensure suitability for athletes and recreational gym-goers alike.

Ascent Native Fuel Micellar Casein is highly reviewed online, with customers particularly liking the flavor and texture of the Chocolate powder.

Nutrition facts per 1 scoop (36 g) of Chocolate Ascent Native Fuel Micellar Casein powder (7):

Best vegan protein powder

Momentous Essential Plant-Based Protein

• Price: $$$$
• Flavors: Vanilla Chai, Chocolate

Why we chose it

If you follow a vegan lifestyle, it may be challenging to meet your daily protein needs. One way to get enough is to include a plant-based protein powder in your diet.

In fact, recent research suggests that a plant-based diet can be just as effective for muscle building as a meat-based diet (9).

Momentous Essential Plant-Based is highly rated for quality and taste.

Momentous Essential Plant-Based is both NSF Certified for Sport and Informed Sport Certified. It’s also certified gluten-free.

It has a smooth texture and mixes easily in a shaker. Reviewers comment that it doesn’t taste chalky, unlike many other plant-based protein powders.

Best grass-fed protein powder

Garden of Life Sport Grass-Fed Organic Whey Protein

• Price: $$$
• Flavors: Chocolate, Vanilla

Why we chose it

The whey protein used in this protein powder from Garden of Life comes from Truly Grass Fed, an animal welfare-friendly and 95% grass-fed dairy farm in Ireland.

Ghost protein powder is made up of a blend of whey isolate and whey concentrate and a blend of digestive enzymes.

While some research suggests that digestive enzymes may be beneficial for some individuals, such as those with lactose intolerance or cystic fibrosis, it’s unclear whether digestive enzymes are beneficial for adults without these conditions (15).

Ghost Whey Protein is produced in a CGMP-certified facility and third-party tested by NSF International to ensure purity and potency. The brand’s whey protein powers are also certified soy- and gluten-free.

Here’s a quick look at how the products compare:

With so many protein powders on the market, it can be difficult to determine which is best for building muscle.

Here are a few factors to consider:

• When will you consume it? Whey is best on either end of a workout, whereas casein is preferable when you want a sustained release, such as before bedtime.
• What’s your budget? Protein powders vary greatly in price. Determine your budget, and then find options within that range.
• Does it come in flavors you like? If you have specific taste preferences, do your research to see whether a given protein comes in the flavor you want.
• Does the company use third-party testing? Third-party testing ensures that the product is free of banned substances and harmful contaminants.
• Is the product manufactured in a CGMP-certified facility? This label ensures adherence to high manufacturing standards set by the FDA.
• Do you have any dietary restrictions? Some protein powders contain potential allergens or substances you may be sensitive to, so it’s best to read the label carefully before purchasing.
• Are all ingredients openly listed? Some companies use proprietary blends to hide specific ingredients and amounts used. Because of this lack of transparency, it’s best to avoid these products.
• Is it properly dosed? A good general rule is to look for a protein powder with at least 20 g of protein per serving to promote muscle gains in combination with resistance exercise (1).

Research shows that consuming protein powder in combination with a resistance training regimen increases muscle protein synthesis, the process of building muscle. This is especially true when protein powder is consumed after workouts (28, 29).

According to some research, the most important factor in building muscle is overall intake of both calories and protein. From this standpoint, protein powders can help increase total protein intake throughout the day, which can promote muscle building (1).

Which protein powder is best for muscle gain?

The most effective post-workout protein powders are ones that are easily digested and contain all nine essential amino acids (EAAs), as well as adequate amounts of leucine — a BCAA that’s important for muscle building (1).

According to the International Society of Sports Nutrition, 1–3 g of leucine is adequate for promoting muscle gain (1).

Whey protein is a popular option because it is easily digested and is a complete protein, meaning it contains all nine EAAs. It can be found in three forms:

• hydrolyzed
• isolate
• concentrate

All of which appear to be equally effective in supporting muscle building (30).

For those who prefer a plant-based option, soy protein has been found to be just as effective as whey protein is for building muscle (31).

Other plant-based protein powders can also be effective, but it’s important to choose one that is made of a blend of plant-based protein sources to ensure it offers all the EAAs needed to promote muscle gain (32).

Casein protein powder is another option that is a slower digesting protein and has been found to be beneficial for muscle gain if consumed before bed because it stimulates muscle protein synthesis overnight (1).

Does protein powder actually help build muscle?

Research does support the use of protein powder, specifically after working out, for building muscle (28, 29).

Some research suggests that an overall increase in calories and protein is important for muscle gain as well. Therefore, protein powders consumed at any time — not just post-workout — can still be beneficial (1).

Which protein powder is best for muscle gain for beginners?

As a beginner, you can try any protein powder you’d like, but it’s a good idea to take time to read the label first to check for any allergens or unwanted ingredients.

Choosing a third-party tested product is always recommended, regardless of your fitness level.

An easy way to get started is to consume a protein shake immediately after your workout to help stimulate muscle building and recovery.

Because protein powders have been studied mostly in adults, teen athletes looking to increase muscle mass can also talk with a doctor or dietitian to determine whether protein powder is suitable for them (33).

For some people, certain ingredients commonly found in protein powders can contribute to acne, including dairy (34).

If you find that dairy causes acne or breakouts for you, switching to a dairy-free protein powder may be beneficial.

A few of the most popular alternatives available include protein powders sourced from:

• egg whites
• bone broth
• plant-based sources like peas or brown rice

Some research also suggests that consuming a high amount of carbohydrates or foods with a high glycemic index — a measure of how much certain foods increase blood sugar levels — can also contribute to acne (35).

Therefore, selecting protein powders that are low in carbs or added sugar might also be a good choice to help keep skin clear.

While protein is an essential part of a balanced diet, consuming too much protein from supplements can cause adverse effects on health.

Some possible signs of excess protein intake include (36):

• weight gain
• kidney problems
• intestinal discomfort
• headaches
• nausea
• diarrhea
• dehydration
• irritation
• fatigue

If you experience any of the symptoms above after adding protein powder to your routine, it might be best to reduce your intake.

How to balance increased protein

If you’re increasing your protein intake, it’s also important to adjust the ratio of other nutrients in your diet to ensure you’re meeting bodily needs.

For example, it’s best to balance high protein foods or supplements with other nutritious ingredients at each meal, including:

• fruits
• veggies
• whole grains
• healthy fats

Rather than depending solely on supplements, you might also want to consume protein from a variety of sources, such as:

• meat
• fish
• poultry
• eggs
• dairy
• soy products
• legumes

Additionally, be sure to drink plenty of water and consume enough fiber, which can help round out your diet and prevent some of the negative side effects associated with high protein intake.

Nutrients to also boost

• Water: Because protein can cause dehydration if consumed in large amounts, it’s crucial to ensure you’re drinking enough water. Adults generally require between 2,000–3,800 milliliters (2 liters–1 gallon) of water per day, but this can vary depending on your:
  • diet
  • activity level
  • overall health status (37)
• Fiber: Eating enough fiber can prevent constipation, a side effect often associated with low carb diets. Fiber recommendations range from 21–38 g per day, depending on your age and sex (38).
• Carbohydrates: While you don’t necessarily need to increase your carb consumption while taking protein powder, low carb intake can worsen some side effects of a high protein diet. Even on a low carb or ketogenic diet, you should still include nutritious, high fiber foods like non-starchy vegetables or low carb fruits (39).

For most healthy adults, it’s not necessary to contact a doctor before taking protein powder.

However, some protein powders may contain ingredients that some people may need to avoid, such as caffeine or certain herbal extracts.

If you have any underlying health conditions or are taking medications and are uncertain about whether a specific protein powder is suitable for you, consider consulting with a healthcare professional before adding it to your routine.

People with food allergies should also pay close attention to the ingredients list of supplements to ensure safety.

If a protein powder causes any adverse effects or an allergic reaction, discontinue use immediately and contact a doctor.

Some athletes and recreational gym-goers have a hard time meeting their protein needs through whole foods alone.

Protein powders provide a high quality source of protein that you can take before or after workouts or between meals to promote muscle gain.

When shopping for protein powder, focus on the quality, taste, price, and manufacturing standards. For the best options, consider one of the products in the list above.
