If you are an ordinary fitness crowd, choose whey protein powder with the highest cost performance. If you are a fat-reducing population, you need to choose to isolate whey protein powder. If you are a lean muscle group, you can have a cup of casein before going to bed.

The following are the key considerations for purchasing protein powder:

1, the source of protein powder. Protein powder can be divided into animal source and plant source according to different sources. The most common animal-derived protein is whey protein and casein separated from milk, while the most common plant proteins are soybean protein, rice protein, soybean protein and hemp protein. Animal-derived protein powder has more advantages and is more common than plant-derived protein powder in nutrition and taste. People who exercise rarely use soy protein, except for religious reasons or the need to supplement estrogen. ?

2. Taste and use of sweeteners. Protein powder itself has no taste, is not sweet or salty, and soybean protein usually has a strong bean smell, so most protein powders will use flavoring agents, or sugar substitutes, or natural, or a mixture of the two. Which flavoring agent has no effect on the nutrition of protein powder, but only affects the taste, but try to choose protein powder as a natural flavoring agent. After all, sugar substitution has an impact on fat reduction efficiency. The taste of protein powder is also very important. The higher the quality of protein, the better the taste. ?

3. Additives in protein powder. Avoid putting some fillers in those cheap protein powders; Avoid those series that put creamer in egg white powder to improve taste and concentration. As we all know, creamer is a pile of hydrogenated oil trans fat and concentrated corn syrup. Common good additives are lecithin, digestive enzymes, amino acids, CLA and cellulose.

To sum up, it is not only a single source, but a mixture of several protein powders according to their ingredients and uses. One of the principles is that the higher the ranking, the greater the content, and the raw materials of each family are basically the same. Therefore, if one company is half cheaper than another in the same scale, the cheaper one is more likely to have low purity of raw materials. Of course, sometimes it depends on whether bad additives are added to the protein powder to reduce the cost or whether there are good additives to enhance the performance.
