Why trust us
Our experts have carefully researched and vetted over 11,000 products to make sure everything we feature meets our standards. We fact-check health claims, evaluate ingredients, and look into each brand’s reputation before sharing products on Healthline.
In addition, to select the nine products on this page, we have:
- evaluated 100+ protein powders
- evaluated products from 70+ different protein powder brands
- tested 12+ protein powders ourselves
Healthline’s dietitians determined the best protein powders using the following criteria:
- Ingredient and nutrient quality: We looked for products that are made from high quality ingredients and contain minimal amounts of added sugars and artificial additives.
- Quality testing: We prioritized products that are third-party tested for quality, accuracy, and purity. We also looked for products that are third-party certified to be safe for competitive athletes.
- Reviews: The protein powders listed below either have been tried and recommended by Healthline editors or have mostly positive online reviews.
- Price: We included options to suit a variety of budgets.
Additionally, every brand and product on our list has been vetted to ensure that it aligns with Healthline’s brand integrity standards and approach to well-being. Each product in this article meets the following criteria:
- FDA compliance: All brands and products adhere to allowable health claims and labeling requirements, per Food and Drug Administration (FDA) regulations. Additionally, products are manufactured in facilities that adhere to the Current Good Manufacturing Practices established by the FDA.
- Medical and business standards: Products are produced by medically credible companies that follow ethical, legal, and industry best standards. Companies also provide objective measures of trust, such as having their supplements validated by third-party labs.
- Health claims: Products don’t make outlandish health or medical claims, and any claims that are made align with Healthline’s approach to well-being.
The type of protein powder you choose depends on your dietary needs, health goals, and personal preferences.
- Whey: Whey is a milk-based protein that’s quickly and easily digested and absorbed. When combined with resistance training, whey protein may help
increase muscle mass,support growth, andspeed up post-workout recovery, so it’s a great choice for athletes. - Casein: Casein is a protein in milk that’s
digested and absorbed slowly , which can help you feel full longer, so it may help reduce your appetite. The slower digestion and absorption ratemay also support muscle growth and recovery over longer periods. - Egg white: Egg white protein is a great alternative to whey or casein protein, especially for people with an allergy to dairy products.
- Collagen powder: Collagen is a component of muscles, and supplementing with it may have benefits for
bone andjoint health. However, collagen is not a complete protein and doesn’t build and repair muscles optimally like other sources of protein, such as whey, pea, and egg. - Plant-based: People following a vegan lifestyle should opt for plant-based protein sources, such as pea or brown rice. These can also be suitable for people who follow a dairy-free diet or have trouble digesting dairy or lactose.
Concentrate vs. isolate vs. hydrolysate
The specific form of protein may also be important to consider.
Whey protein, in particular, is available in concentrate, isolate, or hydrolysate form, although many supplements contain a combination of the three.
Although whey concentrate and isolate offer similar benefits, whey protein isolate undergoes processing methods that result in a higher concentration of protein and lower amounts of fat, carbs, and lactose.
As such, it may be a better option for people who are limiting their consumption of fat, carbs, or lactose.
Meanwhile, whey hydrolysate, or hydrolyzed whey, has been
Protein powder can be a quick and convenient option to increase your protein intake.
This may be especially beneficial for people who have increased protein needs, have difficulty meeting their needs through food sources alone, or have certain dietary restrictions, such as a vegan or vegetarian diet.
Many athletes take protein powder after exercising, which
Additionally, enjoying a protein shake or high protein snack may even
Key factors to consider
- Protein source: Protein powders contain either animal-based or plant-based protein sources. Examples of animal-based proteins include casein, whey, collagen, and egg. Plant-based protein powders often contain pea, rice, soy, or hemp protein. Some vegan blends also contain whole grains, nuts, and seeds.
- Additional ingredients: Look for protein powders that have as few ingredients as possible. Always check the labels carefully, and consider avoiding products containing artificial sweeteners, colors, and flavors.
- Quality testing: Because the FDA doesn’t evaluate the safety, quality, or effectiveness of protein powders, it’s best to choose products that are third-party tested to ensure purity and potency.
- “Safe for sport” designation: Competitive athletes may want to choose a protein powder that has been tested for banned substances by an organization such as NSF International or Informed Sport.
- Flavors and texture: Protein powders come in a variety of flavors, and some mix more easily than others. Online reviews, ingredient lists (specifically the type of sweetener[s] used), and single-serving packets can all help with deciding whether a product will suit your palate or not.
Keep in mind that protein powder shouldn’t be used to replace healthy sources of protein in your diet because high protein foods also provide other valuable nutrients, such as fiber, vitamins, and minerals.
Still, supplements can be an easy and convenient way to increase your protein intake, as there are many ways to use protein powder.
The simplest way is to mix it with a beverage, such as water or milk, or blend it with other ingredients, such as fruits and veggies, to create a smoothie.
You can also mix protein powder into simple foods, such as yogurt, oatmeal, or dips.
If you feel like getting creative, you can experiment with using protein powder as an addition or substitution in your usual recipes. For example, you can use protein powder in soups, veggie burgers, pancakes, and baked goods.
Time-saving tip
To save time, make a larger portion of smoothie mixture and freeze it to make individual ice pops.
When is the best time to take protein?
The best time to take protein powder depends on your health goals. You may want to have one large portion or several small portions of protein per day.
- To lose weight: Try incorporating more high protein foods throughout the day, as
studies show that increasing your intake of protein could help reduce appetite and cravings. - To improve athletic performance or endurance: When to consume protein powder largely depends on your overall fitness goals. While research suggests that the amount of protein you consume throughout the day is
more important than the timing, many experts stillrecommend consuming protein post-training or post-competition. - To build muscle: It’s generally recommended to consume protein powder
within 2 hours of a weightlifting session.Some research also suggests that taking protein powder before you go to sleep may help your muscles recover overnight. But research shows that daily protein intake is the most important factor in muscle building. - To prevent muscle loss: Focus on eating moderate amounts of protein throughout the day to
help prevent muscle loss in older adults.
Protein powders are generally well tolerated and have few side effects, so they’re safe for most adults.
However, certain types of protein may affect you, especially in terms of digestion. Certain types of protein can cause gas, bloating, or stomach cramps. Skin reactions are also possible.
Some supplements could contain contaminants, such as yeast or bacteria, which can cause foodborne illness.
They may also contain heavy metals, which can negatively affect the health of your kidneys, brain, thyroid gland, and reproductive system if consumed in large amounts.
Choosing a high quality product that has undergone third-party testing for purity and potency can help minimize the risk of contamination with these harmful compounds.
If you have a medical condition, are pregnant or breastfeeding, or take any medications that could be affected by protein powders, talk with a healthcare professional before using one.
While there are many excellent protein powder brands, Naked Nutrition and Transparent Labs top our list as two of the best. In addition to being third-party certified by Informed Choice, these brands prioritize high quality ingredients and don’t use artificial additives in their formulations.
Gainful is a great option for beginners, as it creates a custom protein blend based on your dietary needs and fitness goals. What’s more, you can mix and match the Flavor Boosts to find what works for you.
Each subscription also includes personalized nutrition advice from a registered dietitian.
If gaining muscle mass is your goal, research suggests choosing a product with at least 20 g of high quality protein and minimal fillers, sweeteners, and artificial ingredients.
Though any of the protein powders listed above can support muscle gain when paired with resistance training, Gainful is a particularly great option that can be customized based on your specific needs and goals.
Plant-based protein can be a great option for vegans and people who are unable to tolerate dairy. However, whey and plant-based protein powders offer a similar set of health benefits.
For example, some research suggests that whey protein and pea-based protein can be equally effective at increasing muscle growth and strength, as long as they contain the same amount of protein and branched-chain amino acids — a group of amino acids that boost muscle building — per serving.
When trying a new protein powder, pay attention to how your body responds. As with any supplement, you may wish to take a break every so often or alternate between different products.
Many people get plenty of protein from the foods they eat.
However, if you’re trying to increase your protein intake, having a protein shake or adding protein powder to foods, like oatmeal and yogurt, can help you meet your needs.
Finally, try to consume plenty of whole, fresh foods, including natural sources of protein and fiber, as well as plenty of water.
