Best With Hemp

Manitoba Harvest Hemp Yeah! Plant Protein Blend

$21.15 at Walmart $26.99 Now 22% Off Buy on Walmart $21.15

Pros - Organic, non-GMO, and vegan - Provides fiber to support gut health - Provides essential fatty acids to support heart and brain health - No artificial sweeteners or flavors

Cons - Not gluten-free - Hemp seeds may lead to positive drug tests for athletes

Best for: With hemp

Type of protein: Pea and hemp

Protein per serving: 20 grams

Sweetener: None

Price: $26.52 for 16 ounces

Manitoba Harvest Hemp Yeah! Plant Protein Blend earned a spot on our best protein powders list thanks to its use of simple yet thoughtful ingredients. This powder is unsweetened and unflavored, containing only minimal ingredients, without added sugars or artificial flavors. It mixes smoothly into liquids and has a neutral taste, just as you'd expect from an unsweetened product. We also like that each serving offers not only a solid dose of protein but also fiber to support gut health, as well as essential fatty acids, including omega-3 and omega-6, which support heart and brain health.

One unique advantage of Manitoba Harvest's blend is that it provides both hemp and pea protein. Together, these two plant-based proteins provide a complementary amino acid profile, which may offer a well-rounded source of protein that supports your health and wellness.

Also, with USDA Organic, Non-GMO Project Verified, and vegan certifications, Manitoba Harvest's protein powder can suit a variety of diets and is ideal if you're looking for a plant-based product with no additives. However, the product is not gluten-free, so if you have celiac disease or gluten sensitivity, you might need to choose a different option to avoid potential digestive issues.

If you're an athlete, it's important to note that hemp seeds come from the same plant family as marijuana, and while they don't contain the psychoactive ingredient, THC, there might be trace amounts that could lead to a positive drug test.

Best for Muscle Gain

Vega Premium Plant-Based Sport Protein

$37.99 at Amazon $64.99 Now 42% Off Buy on Amazon $37.99

Pros - Each serving is 30 grams of protein for optimal muscle gain - Provides BCAA to support muscle preservation and protein synthesis - NSF Certified for Sport - Includes probiotics and fiber to support gut health - Non-GMO, gluten-free, and vegan

Cons - Stevia aftertaste may be unpleasant - High sodium content is not ideal for people with high blood pressure

Best for: Muscle gain

Type of protein: Pea

Protein per serving: 30 grams

Sweetener: Stevia

Price: $40.49 for 29.2 ounces

Vega Premium Plant-Based Sport Protein is the best protein powder for muscle gain, as it provides an impressive 30 grams of protein per serving—the highest on our list. This amount of protein is particularly useful if you're looking to optimize muscle repair and growth, especially after intense workouts.

We also appreciate that the product provides branched-chain amino acids (BCAA), which are key for building muscle. Research has shown that BCAAs may help reduce muscle soreness, which can make them a good addition to your post-workout routine.

In addition to its muscle-supporting ingredients, this product is NSF Certified for Sport, which means each batch is tested for over 290 contaminants banned by major athletic organizations, including hormones, anabolic agents, and diuretics, among others. Plus, it also includes probiotics and fiber to support healthy digestion.

Vega Sport Protein can fit a range of dietary needs with its non-GMO, gluten-free, vegan profile, and it avoids artificial flavors and preservatives. However, it does use stevia, which has a slightly bitter aftertaste that some might not enjoy. Additionally, while the 430 milligrams of sodium per serving might be beneficial for athletes who sweat heavily, as it helps replenish lost electrolytes, it could be less ideal for those watching their sodium intake or managing high blood pressure.

During testing, Vega Sport dissolved smoothly without any grit, offering a mild flavor with a noticeable stevia aftertaste.

Best Plant-Based

Orgain Simple Plant Protein Powder

$21.99 at Walmart $34.99 Now 37% Off Buy on Walmart $21.99

Pros - Vegan, organic, non-GMO - Gluten-free - Provides fiber to support digestion - No artificial sweeteners, flavors, or colors

Cons - 5 grams of sugar per serving, which is higher than most on our list - Not suitable for those with peanut or tree nut allergies

Best for: Plant-based

Type of protein: Pea

Protein per serving: 20 grams

Sweetener: Coconut sugar

Price: $21.55 for 20 ounces

Orgain Simple Plant Protein Powder made our list thanks to its organic, minimalist ingredient list. With only eight ingredients, including organic pea protein, chia seeds, pumpkin seeds, almonds, and coconut sugar, the product offers plant-based protein that's simple yet effective. The formula is free of dairy, lactose, artificial colors, sweeteners, and preservatives, making it a great option if you're looking for wholesome, straightforward protein powder without unnecessary additives.

Additionally, the use of chia and pumpkin seeds adds a natural source of fiber and healthy fats to the powder, adding to its nutritional value.

Beyond its ingredient simplicity, we also appreciate that this protein powder is non-GMO and gluten-free. However, since it contains peanuts, almonds, and coconut, it may not be suitable for individuals with these food allergies. It also contains 5 grams of sugar per serving, which is more than the other powders on our list and may not be the best option if you're watching your blood sugar.

Best for Men

Nuzest Clean Lean Protein

$44.99 at Walmart $44.95 Buy on Walmart $44.99

Pros - Free from all major allergens - Vegan, non-GMO - Gluten-free - Provides zinc to support men's health - Contains thaumatin, a protein that also serves as a sweetener

Cons - Has a licorice-like aftertaste that may bother some - Contains natural flavors, making ingredients harder to identify

Best for: Men

Type of protein: Pea

Protein per serving: 20 grams

Sweetener: Thaumatin

Price: $42.70 for 17.6 ounces

Nuzest Clean Lean Protein stands out as the best protein powder for men because it not only delivers a solid dose of protein to fuel muscle growth but also a good amount of zinc—a mineral that's especially important for men's health, as it may support muscle gain, testosterone production, and fertility. Zinc also plays an important role in muscle growth and fat metabolism, making it particularly helpful for men looking to build muscle and reduce body fat.

Additionally, research suggests that adequate zinc levels can support testosterone production, a hormone associated with muscle mass and strength, and may even contribute to improved body composition by supporting fat loss. Zinc is also an essential nutrient needed for sperm production and quality, as well as overall reproductive health.

Nuzest Clean Lean Protein Powder has a subtle taste, in part due to the addition of a protein sweetener known as thaumatin, which can create a licorice-like aftertaste that could be off-putting to some. Beyond thaumatin, it's also important to note that the product contains natural flavors, which can be a catch-all term for chemically processed additives derived from natural sources, making it hard to know exactly what's included.

During testing, we found the vanilla flavor to be very mild, but it did have a licorice-like aftertaste. While it dissolved smoothly, we wouldn't recommend drinking it with plain water.

Best for Women

Future Kind Plant-Powered Organic Protein

$53.99 at Amazon $59.99 Now 10% Off Buy on Amazon $53.99

Pros - Vegan, non-GMO, gluten-free - Organic ingredients - Iron-rich to support women's health - Third-party tested

Cons - Sweetened with stevia, which may leave an aftertaste - Not as widely available

Best for: Women

Type of protein: Pea

Protein per serving: 20 grams

Sweetener: Stevia

Price: $53.99 for 32 ounces

Future Kind Plant-Powered Organic Protein has an iron-rich, organic formula to benefit women's health. For women, iron is an essential nutrient and is particularly important for supporting energy levels and blood health. Additionally, research indicates that women are more likely to have low iron levels, especially those with heavy menstrual cycles or higher athletic demands.

We love that Future Kind is third-party tested for quality and packaged in a compostable pouch, a rare but eco-conscious feature in the protein powder market. It's also vegan, non-GMO, gluten-free, and contains just a few, simple, plant-based ingredients. However, one drawback is that it's sweetened with stevia, which can leave a slight aftertaste that doesn't appeal to everyone. Also, it's not as widely available as other protein powders on our list, as it can only be purchased through Amazon or the Future Kind website, limiting your shopping options.

Best Whey

Naked Nutrition Naked Whey

$42.74 at Amazon $44.99 Now 5% Off Buy on Amazon $42.74

Pros - Sourced from grass-fed cows raised on small, non-GMO dairy farms for a richer nutrient profile - Provides BCAAs to support muscle growth and recovery - Contains immune-boosting compounds - Informed Choice certified

Cons - Not suitable for vegans - Can be foamy when mixed

Best: Whey protein powder

Type of protein: Whey

Protein per serving: 25 grams

Sweetener: None

Price: $39.89 for 32 ounces

We like Naked Nutrition's commitment to quality, sustainability, and effectiveness. This whey protein powder is sourced from grass-fed cows raised on small, non-GMO dairy farms, meaning the cows spend more time freely roaming, which may lead to higher-quality milk. This approach benefits both animal welfare and the environment, as grass-fed cows tend to produce milk with a richer nutrient profile.

Each serving of Naked Whey delivers essential amino acids, including BCAAs like leucine, isoleucine, and valine, which are important for building and maintaining lean muscle mass and promoting muscle recovery after exercise. Additionally, grass-fed whey contains immune-boosting compounds like beta-lactoglobulin, lactoferrin, and CLA, which help your body's natural defenses.

With its Informed Choice certification, Naked Whey is rigorously tested for banned substances, making it a perfect option if you're looking for a trustworthy protein powder. That being said, it's important to note that as a whey-based product, it's not suitable for vegans or those with dairy sensitivities.

In our testing, the unflavored variety had a neutral taste, as expected, and blended well in both a blender bottle and a standard blender, resulting in a smooth, creamy texture even when just mixed with water. It does get a little foamy when mixed, but overall, it's versatile for adding to smoothies or other recipes.

Best-Tasting Whey

Primal Kitchen Primal Fuel Chocolate Coconut Whey Protein Drink Mix

$49.99 at Amazon Buy on Amazon $49.99

Pros - Rich, delicious flavor - Sweetened with monk fruit extract with no aftertaste - Gluten-free - No artificial sweeteners, flavors, or colors

Cons - Only 10 grams of protein, the lowest on our list - Higher in saturated fats compared to others on our list

Best for: Best-tasting whey

Type of protein: Whey protein isolate

Protein per serving: 10 grams

Sweetener: Monk fruit extract

Price: $39.50 for 31.1 ounces

Primal Kitchen Primal Fuel Chocolate Coconut Whey Protein Drink Mix has a rich, dessert-like, delicious flavor that we absolutely love. Our tester came in skeptical after hearing the taste compared to that of a Wendy's Frosty, but after trying it, she agreed that it delivered a similar creamy, indulgent flavor. The chocolate coconut blend is subtle, with just a hint of coconut, so even those who aren't coconut fans will still love it. It's also smooth and dissolves easily, leaving no gritty or chalky texture.

We also appreciate that Primal Kitchen's protein powder is made without gluten or refined sugars and uses only monk fruit extract for sweetness. This natural sweetener keeps the flavor profile rich without adding any artificial aftertaste.

While this product has a delicious flavor and clean ingredient list, it does fall a bit short in terms of protein content, delivering just 10 grams per serving—the lowest on our list. This might not be enough for those looking for a higher protein intake to support muscle growth or recovery. It's also slightly higher in saturated fats, due to the use of coconut milk powder, which could be a consideration if you're watching your fat intake or trying to avoid excess saturated fats for heart health.

Best Dairy-Free

Truvani Plant Based Protein Powder Chocolate Flavored

$43.92 at Amazon $46.22 Now 5% Off Buy on Amazon $43.92

Pros - Certified USDA Organic, non-GMO, and vegan-friendly - Gluten-free - Rich, delicious flavor - Contains monk fruit with no aftertaste

Cons - Higher sodium may not suit those with high blood pressure - Made in a facility that handles common allergens

Best for: Dairy-free

Type of protein: Pea

Protein per serving: 20 grams

Sweetener: Monk fruit extract

Price: $40.49 for 23.63 ounces

This chocolate-flavored protein powder is an excellent choice if you're looking for a delicious, high-quality, dairy-free option. Certified USDA Organic, non-GMO, and vegan-friendly, Truvani's formula is made without gluten and contains only a handful of simple ingredients, making it a great addition to your dairy-free lifestyle.

The flavor is rich and chocolatey without any unpleasant aftertaste, as it's sweetened naturally with monk fruit. However, keep in mind that with 290 milligrams of sodium (13 percent of your total daily value), it has a slightly higher sodium content than some other options, which might not be ideal for people monitoring their sodium intake or those who have high blood pressure.

Additionally, while the product itself is free of common allergens, it's produced in a facility that also processes wheat, tree nuts, shellfish, fish, peanuts, and eggs, so it may not be suitable if you have allergies to those ingredients.

Best Casein

Naked Nutrition Naked Casein

$94.99 at Amazon $99.99 Now 5% Off Buy on Amazon $94.99

Pros - Gluten-free, non-GMO - Provides calcium for bone health - Unlike whey protein, may support skin health - Slowly digested for overnight recovery

Cons - Doesn't dissolve easily, has a chalky texture - Most expensive option on our list

Best for: Casein

Type of protein: Casein

Protein per serving: 26 grams

Sweetener: None

Price: $99.99 for 80 ounces

Naked Nutrition Naked Casein is perfect if you're looking for a simple, high-quality protein powder without any additives. With only one ingredient—casein—this powder is great if you're looking for steady, overnight support for muscle recovery and growth.

Casein-based protein powders are generally recommended after a workout or overnight because they're more slowly digested, whereas quick-digesting whey supplements are most often used before a workout to fuel muscles right away. Casein also provides significantly more calcium compared to whey, making it a nice option if you want your protein powder to also support your bone health. Finally, interestingly, casein may also be a better choice if you're prone to acne, as some studies suggest that whey protein could aggravate skin issues in some people.

It's worth noting that Naked Casein doesn't dissolve as easily as other powders on our list and has a slightly chalky texture, so you may be better off mixing it into yogurt or blending it into a smoothie. Additionally, it's on the pricier side, but its pure ingredient list and quality may be well worth it if you're looking for a high-quality casein option.

Best Gluten-Free

Orgain Organic Protein + Greens

$29.94 at Amazon $37.99 Now 21% Off Buy on Amazon $29.94

Pros - Vegan, non-GMO, gluten-free - Provides 35 percent of the daily value of iron - Delivers prebiotics and fiber for gut health - Contains greens to support overall health

Cons - Sweetened with erythritol, which may increase risk of blood clots - Strong alternative sweetener aftertaste

Best for: Gluten-free

Type of protein: Pea

Protein per serving: 21 grams

Sweetener: Erythritol

Price: $25.46 for 32.4 ounces

Orgain Organic Protein + Greens is our favorite gluten-free protein powder that ticks all the boxes for quality and nutrition. It's organic, vegan, and non-GMO, and we love that it provides 35 percent of the daily value of iron, a mineral that is important for women, who may have higher iron needs due to factors like menstruation, as well as people with active lifestyles. Iron also helps transport oxygen throughout the body, which can support energy levels and performance.

This protein powder is formulated with prebiotics and fiber, which are key for maintaining gut health. We also like that this product includes a variety of greens that supply 25 percent of the daily values of both vitamin C, an antioxidant that can support immune health, and vitamin K, which is beneficial for bone and heart health. Both vitamin C and vitamin K are also especially helpful if you lead an active lifestyle.

One potential drawback to this protein powder is that it's sweetened with erythritol, a sugar alcohol that has been linked to an increase in blood clots. Erythritol can also leave a noticeable aftertaste, but this gluten-free protein powder is top-notch, so the aftertaste may be worth it.

Best Budget

NOW Sports Whey Protein Isolate

$29.01 at Amazon $39.99 Now 27% Off Buy on Amazon $29.01

Pros - Budget-friendly - Third-party tested - Informed Sport certified - No artificial sweeteners, flavors, or additives

Cons - Not ideal if you want a flavorful option - Not suitable for people with sunflower allergies

Best for: Budget-friendly

Type of protein: Whey protein isolate

Protein per serving: 25 grams

Sweetener: None

Price: $23.57 for 19.2 ounces

NOW Sports Whey Protein Isolate balances affordability with quality nutrition. Despite its low price, NOW Sports doesn't skimp on quality standards. This product is third-party tested and Informed Sport certified, meaning it's tested for banned substances and contaminants, so you can trust that it meets rigorous quality benchmarks. With 25 grams of protein per serving, it provides an impressive protein boost to support muscle growth and recovery, without unnecessary fillers or artificial ingredients.

We also love its simplicity, as NOW Sports Whey Protein Isolate contains just two ingredients—whey protein isolate and sunflower lecithin—with no additives. However, since it's completely unflavored, it may not suit those looking for something tasty. Mixing it with flavored ingredients, however, like fruit, cocoa powder, or your favorite smoothie mix can add some much-needed flavor to this budget-friendly option.

NOW Sports Whey Protein Isolate contains sunflower lecithin to improve mixability, which may trigger sensitivities in those with sunflower allergies.

Best for Athletes

Klean Athlete Klean Isolate

$53.64 at Amazon $59.60 Now 10% Off Buy on Amazon $53.64

Pros - Provides branched-chain amino acids to support training and recovery - NSF certified for sport - Gluten-free - Non-GMO - No artificial sweeteners or flavors

Cons - Can be foamy when mixed - Pricier than many on our list

Best for: Athletes

Type of protein: Whey protein isolate

Protein per serving: 20 grams

Sweetener: None

Price: $53.64 for 15.73 ounces

Klean Athlete Klean Isolate's high-quality formula provides the essential amino acids for muscle-building, including branched-chain amino acids for optimal training and recovery.

Klean Isolate is a great option for athletes, says Stephanie Darby, RD, a functional performance dietitian for runners. It is plain whey protein, which is rich in amino acids, including all nine essential amino acids needed for recovery. It also contains sodium and potassium, key electrolytes that are crucial for replenishment after a sweaty workout or practice.

We also love that the product is NSF Certified for Sport, which guarantees its free from 280 substances banned by top athletic organizations. Additionally, this unflavored option is versatile, allowing you to easily mix it into beverages, smoothies, yogurt, oatmeal, or baked goods without altering the taste. Plus, with no artificial sweeteners or flavors, it is an excellent choice if you prefer a more natural, straightforward protein supplement.

One thing to keep in mind with this protein powder is that it can get a bit foamy when mixed, which may not be ideal if you prefer a smoother texture. It's also on the pricier side compared to others on our list, so if budget is a priority, this may not be the best choice for you.

Best for People With Diabetes

Legion Whey+ Whey Protein Powder

$56.69 at Amazon $62.99 Now 10% Off Buy on Amazon $56.69

Pros - Made from grass-fed whey protein - Provides BCAA to support muscle preservation and protein synthesis - No added sugars - Non-GMO, gluten-free, lactose-free - Third-party tested

Cons - Users report clumpy texture when mixed - Not suitable for people with sunflower allergies

Best for: Diabetics

Type of protein: Whey protein isolate

Protein per serving: 22 grams

Sweetener: Stevia

Price: $52.64 for 30.5 ounces

Legion Whey+ Whey Protein Powder tops our list for people with diabetes because it combines low-carb, high-quality protein with no added sugars, helping maintain stable blood sugar levels.

With over 15 naturally flavored, low-sugar options like Birthday Cake, Cinnamon Cereal, and Salted Caramel, Legion Whey+ offers a high-quality, all-natural protein powder free from artificial ingredients and added sugars, notes Sydney Lappe, RDN, adding that it is an excellent option for individuals managing diabetes, since it satisfies cravings without spiking blood sugars.

We love that the product is non-GMO, gluten-free, and lactose-free and that it provides BCAAs to help support muscle growth and recovery. Legion Whey+ is also third-party tested to ensure there are no contaminants or banned substances, so you can trust that it delivers exactly what the label says—nothing more, nothing less.

Our research has found that this protein powder can get a bit lumpy when mixed, which isn't ideal if you're looking for a smoother texture. Also, it's not the best choice if you have sunflower allergies, since it contains sunflower lecithin.

Best for Weight Loss

Transparent Labs Grass-Fed Whey Protein Isolate

$59.99 at Amazon Buy on Amazon $59.99

Pros - Made from grass-fed whey - Gluten-free - No artificial sweeteners or added sugars - Informed Choice certified

Cons - Not as widely available as others on our list - Not suitable for people with sunflower allergies

Best for: Weight loss

Type of protein: Whey protein isolate

Protein per serving: 28 grams

Sweetener: Stevia

Price: $53.99 for 39.80 ounces

Transparent Labs Grass-Fed Whey Protein Isolate offers high protein with minimal added ingredients, making it easy to incorporate into a calorie-conscious diet without extra sugars. This whey-based protein powder contains a generous 28 grams of protein per scoop, with only 150 calories, and contains no added sugar, food dyes, or fillers, says Melissa Mitri, RD, noting how the clean ingredient list supports weight management goals.

We like that there are 13 flavor options available, including an unflavored option for versatility. Mitri notes, I love their French Vanilla flavor mixed with almond milk or in a smoothie with peanut butter, banana, and spinach.

We also appreciate that this product is Informed Choice certified, meaning every batch undergoes rigorous testing for banned substances, quality, and purity, offering you an added layer of confidence in its safety. That said, it's important to note that this product isn't as widely available as others on our list and contains sunflower lecithin, making it unsuitable for those with sunflower allergies.

How We Tested the Best Protein Powders

To bring you the best protein powders on the market, we thoroughly tested dozens of products across multiple brands. We carefully evaluated factors like taste, texture, ease of mixing, ingredient quality, and protein amounts. We also took note of sweeteners, third-party certifications, and protein type, to ensure that each protein powder met the needs of various health goals and dietary preferences. With helpful insights from four registered dietitians—Stephanie Darby, RD, Sydney Lappe, RDN, Melissa Mitri, RD, and Cassandra Padula Burke, RDN—we were able to identify products that stood out for their quality, effectiveness, and ability to support different nutritional needs.

As a registered dietitian with over 18 years of experience, I've worked with countless clients and products and understand what separates a high-quality protein powder from one that may not fully deliver on its promises. From protein quality to ingredient transparency, I know which details really matter when it comes to meeting nutritional goals and supporting long-term wellness. This review is meant to help you choose the best protein powder that fits your lifestyle, preferences, and specific health needs.

What to Look for When Buying the Right Protein Powder

Choosing the right protein powder can be overwhelming, especially with so many options out there. The best protein powder should align with your fitness goals, dietary needs, and taste preferences. Here are some key factors to consider when deciding which protein powder is best for you:

Protein type:

Whey is a good option for muscle recovery, since it's quickly absorbed, while plant-based proteins, like pea or brown rice, are ideal if you're dairy-sensitive. For a slower-release option, casein is great to take at night to help with muscle repair while you sleep.

Ingredient quality:

Choose a protein powder with minimal additives—no artificial sweeteners, flavors, or fillers, says Burke. If you see a laundry list of unpronounceable ingredients, it's probably best to leave it on the shelf.

Protein amount:

When choosing a protein powder, look for at least 20 grams of protein per serving, and aim for a higher protein-to-calorie ratio, advises Mitri. She explains that this approach maximizes your protein intake while keeping calories in check, helping you get the protein you need to build muscle and support a healthy metabolism without overdoing it on calories.

Third-party testing:

Check the label for products that have a third-party tested label such as NSF Certified for Sport or Informed Choice certified, explains Burke, as these certification labels mean the product has been tested for quality, safety, banned substances, and contaminants, which is critical for athletes subject to drug testing.

Sweeteners:

When looking at protein powders, check for sweeteners to make sure they fit your taste and health preferences. Some powders use natural sweeteners like stevia or monk fruit, while others contain artificial sweeteners, which may have a stronger aftertaste or could cause digestive issues in some people.

What to Know About Protein Powders

Should I Take Protein Powder?

Taking protein powder can be helpful, depending on your goals and lifestyle, but it's not a must-have for everyone. For people who struggle to meet their protein needs through food alone, such as those with busy schedules, athletes, or individuals following specific diets, protein powder can be a convenient and effective way to boost protein intake. Current research shows that protein supplements can help improve muscle mass and strength, especially when combined with resistance training. This makes protein powder especially helpful if you're looking to build or maintain muscle mass.

However, protein needs vary widely based on factors like age, activity level, and health goals. While most people can meet their protein needs with a balanced diet, others, such as older adults or those recovering from illness or surgery, might benefit from a supplemental protein source. Ultimately, it's best to discuss your needs with a dietitian or your healthcare provider, as they can help determine whether protein powder aligns with your nutritional needs and lifestyle.

Are Protein Powders Healthy?

Protein powders can be a healthy addition to your diet if you choose high-quality options and use them as a supplement to whole foods, not as a replacement. They can be a convenient way to meet protein needs, especially for those with busy lifestyles, intense workout routines, or higher protein requirements.

Studies have found that high-quality protein powders, like those made from whey, pea, or egg proteins, can support muscle growth, recovery, and overall dietary protein intake, without adverse health effects, when used appropriately. However, researchers note that using too much protein powder can place a strain on your kidneys, which could raise the risk of kidney issues over time.

It's important to talk with your healthcare provider before taking a protein supplement, especially if you have any underlying health conditions or are taking medications. They can help ensure that the protein powder is the right option for your individual needs and that you're not consuming more than your body can handle.

What's the Best Type of Protein Powder?

There is no one best type of protein powder. The best choice for you depends on your goals. Are you looking for a plant-based powder or a milk-based one? Is taste your most important factor, or do you want pure protein with no extra ingredients at all?

Many protein powder companies offer trial-size versions of their product, so you can sample a small amount of options before deciding which one is right for you. There is no right or wrong choice, just the right one for your budget, lifestyle, and taste preferences.

FAQ

Should I use protein powder before or after a workout?

The answer depends on your goals. Preworkout protein is helpful for those looking to increase endurance and strength. Research suggests that it primes your muscles for peak performance. For muscle repair and growth, a post-workout protein shake aids in quickly delivering amino acids to your muscle tissues. Unless you are a serious athlete, you may not need either (there's no need to have a protein supplement if you just ate a meal before your workout, for example) and you very likely don't need both.

Do I need to take protein powder every day if I want to build muscle?

No, you don't need protein powder every day to build muscle, but it can be a helpful supplement if you're not getting enough protein from food sources.

Is protein powder good for weight loss?
