I'm not sure why it seems so difficult to find good RTDs, since this is a pretty broad product category and one that seems quite popular, so you'd think companies would have a big incentive to make high-quality products. However, it seems that a fair amount of RTD shakes taste bad or provide a nutritional profile that doesn’t seem ideal for those interested in fitness, typically due to high sugar content. The Premier Protein Vanilla Shake bucks this trend, with a pretty impressive, milkshake-like flavor and a nutritional profile that is appropriate even for those who are dieting. With 160 calories per shake, this isn’t the most filling choice ever, but it is good for a quick snack between meals or for a quick boost before or after a workout. This RTD is perfect for those who don’t want to have to bring along loose protein powder or a blender bottle to the gym, as it provides a nutritional profile similar to the average whey shake, with 30 grams of protein, 4 grams of carbohydrates and 3 grams of fat. This streamlined profile is likely to be popular for those looking to pursue the difficult (or impossible, depending on who you ask) task of gaining muscle while losing fat. Despite being low in carbohydrates, the shack still includes 2 grams of fiber, and the protein blend is preferable to plain whey powder, with milk protein and calcium caseinate for a more filling and extended release effect. Additionally, the shake contains an impressive array of vitamins and minerals, making it a great all-around snack.
