Whey protein

Whey is a product of milk. There are two forms of protein that can be derived from milk, whey and casein. Whey is the liquid product made during the cheese and curd production process. There are several forms of whey protein that can be utilized for different lifestyles. These include Whey Concentrate, Whey Isolate, and Whey Hydrolysate. Of these options whey concentrate is the most popular.

What is Whey Concentrate

Whey concentrate is going to be the cheapest form of whey protein. Once the curd and whey have been separated, the whey goes through filtration. The filtration process for whey concentrate brings the mixture to about 80% protein. This process can and will be continued for a higher percentage of protein (for Whey Isolate and Whey Hydrolysate). The other 20% of this mixture will contain other nutrients, such as fats and carbohydrates.

What is Whey Isolate and Whey Hydrolysate

As mentioned above, the filtration process can be continued to get a higher percentage of protein. For whey isolate and hydrolysate this means getting that percentage to around 90%. A higher percentage of protein means less other nutrients. In addition to having a lower percentage of other nutrients, these forms of whey are better for people with minor lactose sensitivities, this means less bloating and gas. For people who are lactose intolerant and have more severe symptoms, this option may not be the best for you. We would recommend beef protein or a plant based protein instead. For someone with not severe symptoms, you could benefit from whey isolate or whey hydrolysate. Whey hydrolysate is one of the purest forms of whey protein. In addition to being low fat, low carbs, and high protein, it has digestive enzymes. This is going to help break down the protein further.

What Are The Benefits ?

Supplementing with whey protein has several benefits. The most obvious being that supplementing with protein will aid in muscle growth and repair. However whey protein also aids in fat burning, helps with reducing cravings, and can boost your overall immunity. By adding whey to your diet, it can help regulate both ghrelin and leptin (the hormones controlling appetite). This can aid in preventing snacking out of boredom. Because whey protein promotes the synthesis of glutathione, it works to boost your immune system as well.

What To Look For ?

When it comes to selecting the right protein for yourself, there are some things to keep in mind. Such as: are your own diet, when you would chose to supplement with it, price range, and your dietary needs. So shopping around for a quality protein supplement can be difficult, especially when you’re not sure what to look for. To help you navigate through tubs, here are some key things to look for depending on your goals.what is whey quickmass

For these products you’re going to look at the calories per serving v.s. protein per servings. As a reference protein has 4 calories per gram. So if you want to have more of lean bulk, look for a weight gainer with a higher protein per serving. Most weight gainers will contain high carbs and fat, this can be from sugar like dextrose but it depends on the product.
