The top 5 at a glance
A protein shaker is a bottle with a sealed lid and something inside to break up powder as you shake it. Most hold a loose wire whisk that rattles around the bottle, while a few use a strainer instead. Some add twist-on jars for carrying powder, and steel ones are vacuum-insulated to keep a shake cold.
The size on the label is the whole bottle, and the markings inside usually stop short of it, leaving room for the drink to move. Most shakers go on the dishwasher’s top rack, though some makers suggest washing by hand to keep them looking new. Plastic shakers are light to carry, while a steel one is noticeably heavier empty.
What matters
- A cap that locks or snaps shut, for a dry gym bag.
- A size up from your usual shake, so there’s room to mix.
- Dishwasher-safe parts, for a bottle that gets used every day.
- Insulated steel if a shake will sit in a bag for hours.
#1VELOMIX Protein Shaker Bottle, 20 oz (2-pack)
$10–$20
- Two bottles, two whisks
Two 590 mL (20 oz) bottles, each with its own loose wire whisk, so a clean one can go in the gym bag while the other waits for the dishwasher. The lids screw on, with a flip-top spout to drink from, and both bottles are free of BPA and BPS.
What owners say: Owners say the lid seals without a leak and whey mixes with no clumps, and the bottles are simple to wash and carry for a daily shake. On durability, they part ways.
A closer look: Pour the water or milk in before the powder so nothing cakes in the bottom corners, and leave space at the top for the whisk to move. Rinse each bottle as soon as it’s empty so it doesn’t hold a smell, and let the bottle and lid dry apart before packing them again.

#2BlenderBottle Strada Shaker Cup, 28 oz (black)
$10–$20
- Large 828 mL (28 oz) cup
- Resists stains and smells
- Limited lifetime warranty
A push-button flip cap with a sliding lock keeps the spout shut in a bag, on an 828 mL (28 oz) cup of tough Tritan plastic that resists stains and smells. The mixing is done by the BlenderBall wire whisk, which Steve Sorensen first made in Utah in 2000.
What owners say: Owners single out the lid lock and say the cup doesn’t leak, even packed for travel, that powder doesn’t clump in it, and that it rinses clean. The lid itself and durability draw mixed reviews.
A closer look: Press the button to flip the cap open, and slide the lock across once it clicks shut. The flexible carry loop hooks over a finger, the cup, lid and whisk all go on the dishwasher’s top rack, and BlenderBottle makes it for cold drinks, never hot ones.

#3Stanley Vitalize Insulated Shaker Bottle, 20 oz (dried pine)
$50–$75
- Cold up to 8 hours
- Storage cup in the base
- Lifetime warranty
- Heavy at about 610 g
Double-wall vacuum-insulated stainless steel keeps a drink cold for up to 8 hours and ice for up to 30, Stanley says. A removable strainer breaks up the powder in place of a loose whisk, and a small 89 mL (3 oz) container in the base holds the next scoop.
What owners say: It keeps a drink cold and looks good, owners report, and the lid, the mixing and its durability all win praise.
A closer look: It holds 590 mL (20 oz), and at about 610 g (1.3 lb) empty it’s heavier than a plastic shaker, the trade for a drink that stays cold. The soft handle makes it easy to carry, Stanley says it’s dishwasher safe but not for hot drinks, and it comes with a lifetime warranty.
Best for: Keeping shakes cold

#4BlenderBottle ProStak System, 650 mL (22 oz)
$10–$20
- Two twist-on jars, pill tray
Two twist-on jars and a pill tray lock together under the bottle, so the day’s powder, a snack and the vitamins travel as one stack. The jars also work on their own, and a BlenderBall whisk does the mixing inside.
What owners say: Owners find the extra jars really useful for powder and more, and call the whole stack practical and handy, its colour true to the photos. Some find the lid stiff to close, and a few say the cap never shut properly.
A closer look: Fill the jars with dry scoops at home and add the water only when you’re ready to drink, so the shake is fresh. The jars twist apart for washing, the bottle and lid go on the dishwasher’s top rack, and BlenderBottle sells extra jars for anyone who needs a taller stack.
Best for: Carrying powder and pills

#5BioSteel Shaker Cup, 28 oz
$10–$20
- Large 828 mL (28 oz) cup
An 828 mL (28 oz) shaker cup made with BlenderBottle, the shaker brand, whose mark is on the cup, with a loose wire whisk to break up the powder. The lid, which BioSteel calls leak-proof, has a snap cap over the spout, and the cup and lid are BPA-free and go on the dishwasher’s top rack.
What owners say: It’s a solid, durable cup, buyers report, mixing powder well without lumps and cleaning up easily. Leaks and the lid’s closing divide them.
A closer look: BioSteel says the cup and lid can go on the top rack but suggests washing them by hand in warm, soapy water to keep them in shape for longer. Screw the lid down firmly before the first shake and press the snap cap until it closes.
