No, a protein shake is not that important but protein is. And, a protein shake is the easiest source of protein that is also quick to intake. Which mean whatever the benefits protein has a protein shake will also have. So, here are a couple of reasons why it can be very important especially for weightlifters:

Muscle growth:

Protein is essential for muscle growth, and it was obvious. Many athletes and gym goers use this for helping them stacking up the muscle and also sustain it.

A 2018 study of 49 other studies supports the use of protein supplements. These studies show that the protein shakes are significant helpers in muscle growth and strength in adult humans. They were talking about especially the ones who perform resistance training.  These are equally helpful in men and women but the effectiveness may decrease with age. It is because older people have more protein requirements.

Recovery after exercise:

Healing is important for muscle growth as it does that by repairing muscles that are broken down during an exercise or weight training. Many athletes use it for muscle recovery after their muscles are sore from an exercise.

Studies support this claim that protein supplements after exercise can aid in the recovery of muscles and tissues. This, in turn, improves muscle performance and the performance of muscle protein synthesis (a muscle building process).

Weight Management:

A protein-rich food can make us feel fuller and thus taking a protein supplement can have the same effect, or maybe even better. It is because it can have more quantity. Feeling full tends to result in smaller portion sizes, which can help a person maintain a healthy weight or lose weight if necessary. The snacking will also be less. Reduction of body weight and total fat mass in people who are overweight or obese can happen due to taking this protein supplement. This was suggested in a 2017 review. It also reduces blood pressure, total cholesterol and other risk factors of heart-related diseases.

Additional Nutrition:

A protein that is recommended for people aged 19 years and over is 46 g for women and for men 56 grams. People believe it is difficult to find this much source of protein. This is where the protein shake comes as an easier solution.

The recommended dose of protein shake may increase for Athletes, weightlifters, older adult or individuals afflicted with chronic ailments. Having about twice the daily recommended intake of protein, ranging from 1.4 to 2.0 g per kg of body weight is recommended for athletes who practice an intense training program. This equivalent to 111-159 g per day for an individual who is weighs around 175lb.
