A shaker bottle’s main purpose is to mix protein powder with water to make a protein shake. Arnold says, “Ideally, you are using a shaker bottle for a protein shake as soon as possible after a workout. The sooner, the better, but at a minimum, within 60 minutes.”

Glass also allows you to see what you're shaking and generally does not retain odors and flavors, but it is often heavier. The 6-ounce detachable bottom storage compartment, easy-to-read internal measurement markings, and snap-shut design, allow you to take your shakes on the go, worry-free. And the bottle fits into standard cup holders, which a huge plus. We also appreciate the bottom compartment for storing protein powder or other small gym essentials like headphones, hair ties, and more.Superior mixing: There’s a reason why PROMiXX is the number one choice among health and fitness enthusiasts - our bottles give the best mix with Vortex Mixing and X-Blade technologies. What the Experts Say: "If you have any allergies, sensitivities, or other contraindications with medications you're taking, you should be cautious when choosing a protein powder. Consulting with your healthcare provider is always a good idea," says Allison Knott, MS, RDN, CSSD. And while you could reach for a turkey sandwich or Greek yogurt with a banana, an on-the-go protein drink is way more convenient than carrying around food. All you have to do is combine protein powder with the liquid of your choice, screw the lid on tight, and shake away until your drink is thoroughly mixed. The fact that it’s a blender also means you can add more nutrition to your protein shake by adding frozen fruits or vegetables for added vitamins, minerals, and fiber. And you’re not limited to protein shakes. This blender can be used to make your favorite frozen drink — think margaritas, smoothies, or frappes.

We were impressed by this bottle’s unique design. It’s divided into two sides: a 14-ounce section for your pre-workout drink and a 22-ounce section for your post-workout drink. Each section has a separate mouth spout, and the bottle does an overall nice job of preventing the two liquids from mixing. Our tester said, “Very thorough and effective product! A lot of thought was put behind the compartment system and how to effectively mix powders in each compartment independently.” Brands on the market offer anywhere from 16- to 24-ounce bottles as well as larger versions in whopping 45-ounce volumes. Whatever you spring for, ensure it’s easy to grip and shake to avoid messes when you're in a pinch. The smallest bottle on our list is the Blendjet 2 at 16 ounces, while our largest, Matrix’s Insulated Shaker Bottle, has a 30-ounce capacity. Material

Testing Notes: “I would recommend this product to anyone who's looking for a bottle that can double as a workout bottle and as a bottle you can take to work and put any beverage in.” Your bottle’s internal mixing system should be effective enough to blend any powder into your liquid base. Options ranging from metal or plastic whisk-like balls to solid silicone or plastic mechanisms will all efficiently break up clumps. And bottles with screens, like Matrix’s Insulated Shaker Bottle, agitate ingredients just as well while shaking. 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. They can be made of whey, casein, soy, pea, or other sources of protein in powdered form that you mix with a liquid. Most people enjoy them as a convenient means of upping their protein intake. The old-school shaker bottle is often cheaply made. And really, it’s not even the actual “unreliable hand-shaking technique” of the protein shaker cup that’s the problem.
