An increasingly popular dietary product consisting of high biological value proteins is extracted from whey. Its known as whey protein, and as mentioned above, it contains all essential amino acids, which are those that the body absorbs the best.

This milk drink, which is usually sold as a powder and combined with other ingredients, is very common among athletes due to its excellent properties.

According to the experts at Medline Plus, “whey protein is commonly used to improve athletic performance and increase strength, but the evidence to support this is conflicting.” Therefore, it’s considered it may possibly provide benefits, but these are still being studied.

How to choose the right whey protein

Some supplements, such as creatine and HMB, have shown positive effects on muscle mass gain and weight loss in athletes.

Depending on the manufacturing process, whey protein is considered to be more or less beneficial. The varieties and criteria usually taken into account are as follows:

  • Whey protein isolate: obtained by removing the fat and lactose. It also has a lot of protein. However, experts don’t recommend this variety because manufacturers use acids during the process and heat it at high temperatures, so it loses many of its properties. Also, it’s usually more expensive because it’s a processed product.
  • Whey protein concentrate: this product is obtained prior to the aforementioned isolated process. It contains certain amounts of fats and lactose, and less protein. However, it’s more natural and balanced.
  • Organic quality: in addition to choosing the concentrated option, it’s a good idea to choose an organic product. This way you’ll be sure that the cows used to make it were fed without pesticides or herbicides. Also, the resulting product is richer in nutrients.
  • Other ingredients: when choosing a brand, you have to read the label to make sure the other ingredients are also of good quality. You should avoid those containing sugar, sweeteners, and artificial colors or flavors. The best sweetener for your smoothie is stevia and the flavors should be natural extracts.
