Best Protein Shakes

Verywell / Chloe Jeong

Do you ever feel like you need a protein boost? While meeting all of your protein needs through food is ideal, sometimes life gets in the way. When that happens, a protein shake can help give your body the nutrients it needs. That said, protein shakes aren’t always essential for muscle building.

“Everybody needs a certain amount of protein in their diet. Most people need between 45 and 56 grams per day for regular activities” says Dr. Kathryn A. Bohling, MD, a family medicine specialist at Mercy Medical Center in Maryland. “People who may benefit from protein shakes include people who aren't getting enough protein in their diet because of dietary restrictions, those who are trying to lose weight, or anyone trying to build muscle”.

In general, a protein-rich meal consumed three to four hours before a workout will suffice. But, on those days when you need a grab-and-go source of protein, a convenient, ready-to-drink shake or a scoop of high-quality protein powder mixed into your favorite beverage are great options.

What to Look for in a Protein Shake


Protein shakes, both pre-made and powdered, can come from a variety of animal and plant-based protein sources, including whey, pea, brown rice, and hemp. Depending on your goals, consider choosing a product that contains the best protein to meet your needs. For example, whey is a top pick for athletes, whereas pea and hemp are excellent choices for vegans.   

Macronutrient Breakdown

One of the appeals of a protein shake is that it often comes with ingredients other than protein. Look for powders that also have a balance of carbohydrates, fat, and fiber. Try to avoid products with added sugar. Consider choosing a shake that contains additional beneficial ingredients, including added greens, BCAAs, digestive enzymes, or probiotics.


Protein shakes and powders come in a wide range of flavors from chocolate and vanilla to golden milk and banana. Depending on the ingredients, some may taste more chalky or artificial than others, even if the sweetener is technically plant-based. Always try to choose a product with natural flavor and no artificial ingredients.

Protein Shakes Dosage

Always speak with a healthcare professional before adding a supplement to your routine to ensure that the supplement is appropriate for your individual needs and which dosage to take.

The Dietary Reference Intake (DRI) for daily protein intake is 0.8 grams of protein per kilogram of body weight per day for adult men and women, and it is widely recommended that protein needs increase the more active a person is. Studies have shown no safety concerns at daily recommended intakes up to 2.0 grams of protein per kilogram of body weight a day.

Frequently Asked Questions

  • How many protein shakes can I have each day?

    Protein shakes are one way to incorporate additional macro and micronutrients into your diet. They are best consumed as part of a balanced diet, including whole grains, fruits, vegetables, healthy fats, and protein.

    Recommended daily intake of protein shakes depends on individualized nutritional needs. For example, a high-endurance athlete may require a higher daily intake of protein and calories. Therefore, they may want to incorporate more protein shakes in their diet to meet their needs. You should consider your daily intake goals for protein and calories to determine the quantity of protein shakes to consume.

  • Are protein shakes good for weight loss?

    Protein shakes can support weight loss but must be considered within the context of the diet in its entirety. Effective weight loss plans consider the overall nutrition value of the diet as well as macronutrient intake, including protein and overall calorie intake. Whether protein shakes serve as meal replacements or snacks, they should be incorporated into a balanced diet, including whole grains, fruits, vegetables, healthy fats, and protein. 

    Keep in mind that drinking calories in the form of a shake versus eating calories may result in suboptimal satiety levels, which can lead to compensatory overeating come your next meal. Additionally, many protein shakes contain a significant amount of calories and added sugars, so it’s important to ensure you are not consuming excess calories and sugar through shakes when trying to lose weight.

    Try swapping in a homemade protein smoothie for breakfast with one serving each of protein powder, fruit, leafy greens, and unsweetened nut milk—you’ll get the added benefits of fiber, antioxidants, and protein to keep you feeling fuller for longer.

  • Can protein shakes help you gain muscle mass?

    Adequate dietary protein intake is essential for optimal muscle protein synthesis. Protein shakes are one way to increase your daily protein intake, but they are not necessary for gaining muscle mass. Incorporating protein at each meal through animal and plant-based proteins should be considered. The American College of Sports Medicine estimates that the protein requirements for strength trainers are 1.6 to 1.7 grams per kilogram of body weight per day (about 0.8 grams per pound) and may require an intake of up to 2.0 grams per kilogram of body weight per day.

    Some evidence suggests that protein supplementation before and/or after endurance or resistance training may enhance muscle recovery and rebuilding. Incorporating a shake with one serving of protein powder, fruit (try banana), and milk or plant-based milk alternative may help to replenish carbohydrates and electrolytes lost through exercise and support muscle recovery post-workout.

  • When should I drink a protein shake?

    Depending on the protein shake's nutrition profile, it can serve as a meal replacement or a supplemental snack. Consider your daily routine and overall dietary intake to determine when a protein shake may fit best into your diet.

    For example, a protein shake may be a good option for an on-the-go breakfast if you don’t have time to prepare a meal. If you practice resistance or endurance training, some evidence suggests that protein supplementation before and/or after training may enhance muscle recovery and rebuilding.

The plant-based powder blends well into your favorite beverage and comes in three delicious flavors, including vanilla, chocolate, and natural.

“Protein shakes are a great way to get easily digestible protein to your muscles right after a workout, which can help speed recovery and build muscles more efficiently. They can also be used as a quick on-the-go meal replacement to help with satiety, keeping you full until your next meal or snack.”—Rebekah Blakely, RDN

Best Dairy-Free: ALOHA Organic Plant Based Protein Shake

ALOHA Organic Plant Based Protein Shake
  • Only 5 grams of added sugar per serving

Made from a mix of organic pea and brown rice proteins, ALOHA's Protein Drink provides easily digested, plant-based protein that will give you an extra boost without tummy-troubling dairy proteins.

The USDA Organic beverage is perfect for those who have a sensitivity to dairy or those who prefer plant-based products.  It comes in three craving-worthy flavors, including Coconut, Chocolate Sea Salt, and Vanilla. It's also gluten-, soy-, and dairy-free.
