Our tester found it easy to use and to clean, noting: “The paddles along the ball is an interesting design that you don't usually see in shaker bottles, and this made it easier to clean as opposed to a standard wired/spiraled shaker ball.” It only took about 30 seconds for this bottle to make a smooth, well-mixed protein shake with no residue caked on the bottle. This shaker bottle is a simple, affordable one with thoughtful touches that make it our best overall pick. It’s Worth Noting: This bottle isn’t insulated. Why We Like It: The shaker ball has an easy-to-clean design and creates a smooth protein shake. We tested multiple shaker bottle options on the market, considering their design, mixing effectiveness, and ease of cleaning. Their capacity varies, with most ranging from 16 to 28 ounces. Many shaker bottles are made of BPA-free plastic, which is valuable because BPA has been linked to a variety of health concerns, including cancer and polycystic ovarian syndrome (PCOS).

Shaker bottles typically either come with an agitator ball or lid inside the bottle or are designed in another way that helps mix the protein powder with water to create a deliciously mixed protein shake. If you have a regular shaker bottle you use, you can develop a habit of regularly taking the same bottle to the gym every time you go.” Since the ideal protein shake must be well-mixed, a regular bottle doesn’t usually do the trick. Kristen Arnold, MS, RDN, CSSD, sports dietitian and cycling coach, says, “Shaker bottles are helpful for developing regular habits to ensure high-quality protein post-workout. Most people enjoy them as a convenient means of upping their protein intake.

They can be made of whey, casein, soy, pea, or other sources of protein in powdered form that you mix with a liquid. If you’re an athlete, weight lifter, or generally struggle to meet your protein needs, protein shakes may be a useful addition to your diet.
