What the AI looks for in Sports Nutrition Ready to Drink Protein

Protein per bottle
Look for at least 20 g of protein per bottle for a meaningful serving. Higher-protein versions reach the 30 to 40 g range. Some protein drinks contain far less than a scoop of powder.
Protein source
Milk protein concentrate, whey or a mix of casein and whey are the strongest choices. Avoid drinks where collagen is the main protein. The source determines how complete the protein is and how much leucine it provides.
Sugar and sweeteners
Check added sugar on the label and note which sweetener is used, such as sucralose, stevia or monk fruit. The sweetener is the main driver of aftertaste complaints and of fit with your diet.
Shelf-stable vs refrigerated
Aseptic or UHT-processed bottles keep at room temperature until opened. Refrigerate after opening. This affects bulk buying, travel and use in a gym bag.
Third-party testing
Tested athletes should choose NSF Certified for Sport or Informed Sport products. Ready-to-drink shakes face the same contamination risks as powders.

Questions

Are ready-to-drink shakes as good as powder?

The protein quality is comparable when the source is milk or whey. You pay for convenience, and powder costs less per gram of protein.
