What Type of Protein Powder Is Best?

Protein powders are popular choices for fitness enthusiasts and gym-goers alike who want to build muscle and improve athletic performance. With that said, protein powder isn’t just for the gym bros and health nuts out there; protein is also an essential macronutrient that everyone needs on a daily basis for optimal health and longevity. 

This is why the best protein powders are such popular nutritional supplements, especially for those who struggle to consume enough protein through whole foods. A good protein powder can also serve as a convenient meal replacement for when you’re on the go or pressed for time.

With that in mind, there is no type of protein powder that is best for everyone. A multitude of factors must be considered, notably:

  • Where the protein comes from
  • Protein content per serving
  • Ingredient quality

To choose the best protein powder, you need to determine which protein sources suit your lifestyle and goals.

Do you know where your protein comes from?

You should also opt for protein powders that have as few ingredients as possible. Less is more when it comes to all the “additional” ingredients you find in protein powder. Check the ingredient panel and verify that it’s not loaded with added sugars, artificial colors, or other unnecessary junk. 

Animal-Based Protein Sources

The most common animal-based protein sources in protein powder include:

  • Whey protein
  • Casein protein
  • Milk protein (a mixture of whey and casein)
  • Egg protein
  • Beef protein
  • Collagen peptides (bovine, porcine, or marine)

Aside from collagen peptides, all of these are good sources of essential amino acids that help build muscle and support recovery after a tough workout. Whey protein has the highest biological value of any protein source, followed closely by egg protein and casein protein.

Whey, egg, and casein are the most useful sources of protein for humans from a biological standpoint. This also makes them exceptional for building muscle.

What About Collagen Protein Powder? 

Collagen is unique in that it is actually rich in amino acids like alanine, glycine, and proline, which are major constituents of connective tissues like tendons, ligaments, and bone, though not skeletal muscle tissue. Thus, you shouldn’t rely on collagen protein powders for muscle building or meeting your dietary needs of protein. 

The purported “anti-aging” benefits of collagen supplements for skin, hair, and joints remain controversial, so it’s best to approach these “protein powders” with caution.

Plant-Based Protein Sources

Vegans and those who follow a strict plant-based diet should steer clear of whey, beef, egg, and casein proteins since those proteins are derived from animals. The good news is there are also plenty of plant-based protein powders out there. 

Something to keep in mind when choosing a vegan protein powder is that plant proteins typically have an “incomplete” profile of essential amino acids. This means they lack one (or more) of the amino acids necessary for muscle protein synthesis — in other words, one of the “building blocks” of muscle tissue is missing or negligible in plant-based protein. 

Never fear Vegans, you can still get complete protein synthesis!

Thankfully, vegans can work around this conundrum by choosing a vegan protein powder with multiple plant protein sources that complement one another and create a “complete” amino acid balance. 

Such plant-based protein sources include:

  • Pea protein
  • Brown rice protein
  • Hemp protein

Pea protein isolate is arguably the best plant-based protein. It’s made in an eco-conscious manner from yellow split peas and has a high biological value for humans, not to mention it’s rich in essential amino acids and ideal for those who are allergic to dairy and eggs.

Moreover, research suggests that consuming pea protein reduces blood pressure and improves renal function by inhibiting angiotensin-converting enzymes (ACE). Frankly, even those who don’t follow a vegan diet stand to benefit from pea protein.

What About Soy Protein Powder? 

Despite the common misconception that it increases estrogen levels, soy protein powder is a viable plant-based protein. In fact, soy protein is demonstrably beneficial for both men and women, especially for cardiovascular and metabolic health. However, it’s best to limit the intake of soy protein to 40 grams or less per day, particularly if you’re male.

How to Use Protein Powders

There are myriad ways to use protein powder. Naturally, the most practical way is to make a protein shake. Simply mix the powder into a liquid, either water or milk, and stir or shake it up with a spoon, blender, or shaker bottle.  Protein shakes are undoubtedly convenient and how most people use their protein powder.

Now, if you want to live life on the edge and add more protein-packed flavor to your diet, try mixing protein powder into things like yogurt, oatmeal, soups, and cottage cheese. Believe it or not, you can use protein powder in tons of recipes, especially when baking things like bread, muffins, and cake. 

Believe it or not, you can use protein powder in tons of recipes, especially when baking things like bread, muffins, and cake. 

Intuitively, you’ll need to determine if the flavor of the protein powder makes sense in what you’re adding it to. For instance, chocolate-flavored protein powder might not mesh well with chicken noodle soup.

When to Take Protein Powder

Protein powders are dietary supplements meant to help people meet their total daily needs of protein. The time at which you take protein powder isn’t a big concern as long as you consume enough protein throughout the day.

Most gym-goers, athletes, and fitness enthusiasts find that slamming a whey protein shake after finishing their workout is a nice “treat” that kickstarts the muscle-building process, but protein powders can be used any time of day, really. 

Down a protein for a nice post-workout treat.

However, there is good evidence that taking at least 20 grams of whey protein powder shortly before and/or after hitting the gym improves muscle building, performance, and recovery, so this would generally be considered the “best” time to take whey protein powder. Both whey protein concentrate and whey protein isolate are rapidly digested and contain all the essential and non-essential amino acids. 

For the veggie lovers out there, brown rice protein is a great alternative to whey protein powder after you hit the gym. In fact, a recent study showed that people taking either rice protein isolate or whey protein isolate after resistance-based exercise had virtually identical improvements in lean body composition (fat-free body mass) and exercise performance (strength and power) over the course of eight weeks.

Casein protein powder is typically the better nighttime option since it’s slowly digested and absorbed, helping recovery while you sleep. Similar to whey protein, casein contains a complete profile of amino acids for supporting muscle growth and recovery.

There is good evidence that taking at least 20 grams of whey protein powder shortly before and/or after hitting the gym improves muscle building, performance, and recovery, so this would generally be considered the “best” time to take whey protein powder.

Beyond that, simply take protein powders as needed throughout the day to keep you on track towards your protein intake goal. Remember, even if you’re using the best protein powder out there, it will not make up slacking on your diet. 

Is Protein Powder Safe?

Assuming you’re taking a good protein powder that isn’t loaded with allergens or other unnecessary additives, chances are your powder will be well-tolerated, and you’ll experience few, if any, adverse effects.

In some cases, protein powder can cause flatulence, bloating, stomach cramps, and diarrhea. Note that this typically only happens if the protein powder contains excess amounts of lactose, wheat, or other indigestible/intolerable ingredients. Skin reactions are also possible, particularly if the protein powder contains something you’re allergic to. 

To avoid any unwanted side effects be sure to get a high quality supplement.

Furthermore, since dietary supplements are not officially regulated by the Food and Drug Administration (FDA) or the United States Department of Agriculture (USDA), it is possible for companies to be less than forthright about what their products contain. That’s why it’s imperative to choose a protein powder from a brand that has a respectable reputation for making quality nutritional supplements.  

Always check with your doctor if you’re pregnant, breastfeeding, have a medical condition, or take any prescription medications before you start taking protein powder (or any supplement). The ingredients in protein powder may interact with certain medications or exacerbate the symptoms of some medical conditions, notably renal dysfunction.

Best Animal-Based Protein Powder

Ingredient Quality: 100/100
Taste: 86/100

You won’t find any artificial flavors or sweeteners in this clean whey protein powder. All of the protein in Naked Goat Whey comes from cold-processing (acid and bleach-free) of goats’ milk, resulting in one of the cleanest whey protein powders you can find anywhere. With 23 grams of protein and 4.6 grams of branched-chain amino acids per serving (30 g), this is an exceptional alternative to traditional whey protein powder.

Naked Goat Whey is available in chocolate and vanilla flavor options (which are sweetened only with coconut sugar), or unflavored.

Protein Powder Takeaways

On a final note, pay attention to how your body responds when you use a new protein powder. If you find that whey protein concentrate makes you gassy and bloated, try a different protein powder with other protein sources instead. Ultimately, you’ll only figure out which protein powder works best for you by trying different products and assessing your response. 

Remember, protein is a vital macronutrient that we all need for optimal health, longevity, and athletic performance. Active individuals who want to build muscle should aim for a daily intake of about 0.8-1.2 grams of protein powder per pound of body weight. Those who just want to maintain their wellness and live a healthy lifestyle can get away with about half that amount.
