Protein powders are powdered forms of protein that come from plants (soybeans, peas, rice, potatoes, or hemp), eggs, or milk (casein or whey protein). The powders may include other ingredients such as added sugars, artificial flavoring, thickeners, vitamins, and minerals. The amount of protein per scoop can vary from 10 to 30 grams. Supplements used for building muscle contain relatively more protein, and supplements used for weight loss contain relatively less.
We should aim for the Recommended Dietary Allowance for protein intake: 46 grams per day for women and 56 grams for men. The goals are very important if you want to enhance your daily intake. In short, you should be aware about your fitness goals and on that basis protein intake should be increased or decreased.Protein supplements are added in diet in case you are unable to meet daily requirements with diet. The same should be taken under the supervision of a dietitian.
How much protein to eat, when to eat it and whether we should supplement with it (by drinking protein shakes, for example) has been debated by scientists for years. The current consensus points towards a slightly greater need than normal for people who take part in intense training, depending on their goals.
The conclusion here is that one should know about their lifestyle, activity and fitness goals and basis of that to decide whether to go ahead with protein supplements or not. My opinion here is protein from food should be primary and supplement secondary.
