Are ready to drink protein shakes healthy?

They can fit a healthy diet if they are low in added sugar and match your protein needs. Read added sugars, calories, allergens and the whole nutrition panel instead of choosing by the front protein number alone.

How much protein should a ready to drink shake have?

It depends on your needs. ODS gives about 20 grams per serving for a 150-pound person as a reference for spreading protein through the day.

Can I drink a protein shake every day?

Many people do, but ODS says there is no benefit to eating more protein than recommended. Count the shake toward your daily total, and ask your doctor first if you have kidney or liver disease.

When should I drink a protein shake?

ODS reports that experts suggest high-quality protein every 3 to 5 hours, including within 2 hours after exercise.

Are ready to drink protein shakes good for teenagers?

Most teens can get enough protein from food. ODS says talking to a health care provider is especially important before teens use performance supplements.

Ready to drink protein shakes: how to read the label and pick one that fits

Quick answerReady to drink protein shakes are bottled or boxed shakes you can drink straight from the fridge or bag. A good one gives a useful amount of protein for your needs, keeps added sugar low on the Nutrition Facts label, uses a protein source your stomach tolerates, and, if you compete in sport, carries a third-party mark such as NSF Certified for Sport. Most people can meet their protein needs from food, according to the NIH Office of Dietary Supplements, so a shake is a convenience, not a requirement.

Compare the picks and what to watch out for

How much protein do you actually need?

Start here, because it decides how much a shake should give you. The Harvard T.H. Chan School of Public Health Nutrition Source cites a minimum of 0.8 grams of protein per kilogram of body weight per day, or just over 7 grams for every 20 pounds. That works out to about 50 grams a day for a 140-pound person and about 70 grams for a 200-pound person.

Athletes need more. The NIH Office of Dietary Supplements (ODS) says athletes need about 0.5 to 0.9 grams of protein per pound of body weight a day, or about 75 to 135 grams for a 150-pound person. It reports that sports science experts suggest spreading high-quality protein through the day, every 3 to 5 hours and within 2 hours after exercise, at about 20 grams a time for a 150-pound person.

ODS adds two points worth remembering: high protein intakes seem quite safe, but there is no benefit to consuming more than recommended amounts, and most athletes can probably get enough protein from food.

How to read the label on a protein shake

FDA's Daily Values make the label easy to judge. FDA sets the Daily Value for protein at 50 grams and for added sugars at 50 grams, and says 5% Daily Value or less per serving is low while 20% or more is high.

Protein per bottle. Match it to your goal. For a post-workout drink, the ODS figure of about 20 grams for a 150-pound person is a useful reference.
Added sugars. Look for a low %DV. Check the actual bottle for added sugars and calories; the protein number alone does not describe the whole drink.
Saturated fat and sodium. FDA's Daily Values are 20 grams for saturated fat and 2,300 milligrams for sodium. Check the %DV if you drink a shake every day.
Calcium. Milk-based shakes often list calcium. FDA's Daily Value is 1,300 milligrams.
Which panel? Some shakes carry a Nutrition Facts panel and others a Supplement Facts panel. Compare the amounts per serving and the daily values shown on the actual panel; do not assume the panels present every detail identically.

Dairy or plant protein?

Protein source	Who it suits	Trade-off
Milk protein (whey, casein or milk protein concentrate)	Most people who tolerate dairy	Not for people who avoid dairy
Plant protein (pea, soy or blends)	Vegans and people avoiding dairy	Texture and taste vary more between products

Harvard emphasizes that the whole protein package matters, including accompanying fat, fiber and sodium. For a bottled shake, read which protein source and other ingredients the manufacturer lists. A shake with a long list of sweeteners and thickeners is not a like-for-like swap for a meal of whole foods. If you prefer to mix your own, compare whey protein isolate and plant-based protein powder with a shaker bottle.

Quality and safety: what a seal means

ODS states that FDA does not test or approve performance supplements before they are sold; manufacturers are responsible for their safety. Read every listed ingredient, particularly for products with a Supplement Facts panel. FDA has warned that some performance products contain unlabeled stimulants, steroids or prescription drugs, according to ODS.

ODS names three third-party programs that check for banned ingredients: NSF Certified for Sport, Informed-Choice and the Banned Substances Control Group. Products that pass may carry the certifier's logo and are listed on the certifier's website. If you are a tested athlete, look the product up on that list rather than trusting the logo alone.

Who should be careful

Kidney or liver disease. Harvard says people with these conditions need to monitor their protein intake according to their physician's guidelines. Ask before adding shakes.
Teenagers and people with medical conditions. ODS says talking to a health care provider or a coach with sports medicine knowledge is especially important for these groups.
Meal replacement. Do not assume a protein drink is nutritionally complete because it is marketed as a shake. Check its intended use and nutrition panel. If that is your aim, see our guide to meal replacement shakes.

What to look for when you buy

High protein ready to drink shake with low added sugar

Best for: Post-workout or a protein boost between meals

ODS suggests about 20 grams of protein after exercise for a 150-pound person, and FDA says 5% DV or less of a nutrient is low. A shake that hits your protein target with a low added sugar %DV checks both boxes.

Watch out: Check sodium and saturated fat %DV too, especially if you drink one every day.

Plant-based ready to drink protein shake

Best for: Vegans and people who avoid dairy

Read the ingredient and allergen statements for the actual bottle. A shake made with plant protein may fit a dairy-free preference, but check for other milk ingredients rather than relying on its name.

Watch out: Texture and taste vary widely; buy a small pack first.

See options on Amazon

NSF Certified for Sport ready to drink shake

Best for: Athletes in tested sports

ODS names NSF Certified for Sport as a program that checks for banned ingredients, with passing products listed on the certifier's website.

Watch out: Confirm the exact product and flavor on the certifier's list before you rely on it.

See options on Amazon

Shelf-stable protein shakes in a multipack

Best for: Keeping in a pantry or desk within the labeled storage conditions

Shelf-stable cartons do not need refrigeration until opened, so you can have one on hand after a workout within the storage conditions on its label.

Watch out: Read the storage line: most need refrigeration once opened and have a use-by date.

See options on Amazon

Protein powder and shaker bottle

Best for: People who drink a shake most days and want to set the dose

Mixing your own lets you compare the labeled serving amount with your protein needs, in line with the ODS guidance that more than the recommended amount brings no added benefit.

Watch out: Less convenient on the go, and the same label checks for added sugar apply.

When to talk to a doctor: If you have kidney or liver disease, ask your doctor how much protein is right for you before adding shakes. Talk to a health care provider before teenagers use protein or other performance supplements, and check the allergen line if you have a milk or soy allergy.
