What does Grass-fed Whey Protein Isolate do?

Well, possibly everyone knows what protein powder is, and what its purpose is, but we will repeat it again. Firstly, what is protein? Protein is a macronutrient that is essential to building muscle mass. It is commonly found in animal products, though it is also present in other sources, such as nuts and legumes. 

So, we can compare it with bricks, when you are building a house, just it is building your muscle. 

As you possibly know, you can get protein from different products, like meat, beans, fish, etc. But, it is quite difficult to eat so much meat, and whey protein is making it so much easier, and it is delicious, which makes it perfect, diet dessert. 

So, what is whey protein isolate then? 

Whey protein isolate is a cleaner protein than whey protein concentrate. It is absorbed faster by you body, and it works faster. Also, Whey Protein Concentrate contains around 80% protein contents, whereas isolate contains around 90%.

Whey protein isolate goes through a process called ‘Cross-Flow Mico-filtration’. This simply separates the protein from fat and isolate from milk, cholesterol, and lactose, giving it that ultra-pure end product. This also means that Whey Protein Isolate has much less fat, carbohydrates, lactose, and also calories than any other protein shake on the market.

What should you check before you buy Whey Protein?

There is a really big amount of whey protein products on the market. So, here we want to let you know what you need to pay attention to first before you buy your supporter in the way of gaining muscles.

Protein amount and content:

First what you need to pay attention to is the amount of protein in your product, usually, it variates about 20-30 grams per serving. Also pay attention that, very often it is a mix of proteins, what is not always bad, for example, casein is a longer absorbing type of protein that is not bad. It can be good for you if you are using it in the evening, it will feed your body with protein during sleep. Of course, better is to avoid a big amount of soy protein, because vegetable protein has not full amino acids composition in it. But from practice, even if whey protein contains soy protein, usually it is a small amount. Anyway, just do not be lazy and check the back of the box (1). 

Type of Whey: 

As we wrote before, there are some different types of whey protein. Every type of protein has different pros & cons. Most popular is isolate, this type of protein is fast absorbing and is one of the top quality proteins are used on the market. Also, there are such types as whey protein concentrate which is slower but doesn’t mean that it is worse for you, isolate or hydrolyzed wheys are better to use instantly after your workout. It is also mentioned in the previous sentence hydrolyzed whey protein is the fastest one and the purest one, but usually, the price is higher for it. So, depending on your goal, you can choose one of these three mentioned above, but a mix of protein is a really good choice too. Mixed type whey can be a good choice, usually, they are well balanced (2).


Nowadays we have a huge amount of companies in the supplement industry, but to make a good choice of whey protein we need to watch on a trusted brand.

Above all, don’t try to choose the cheapest one, usually cheap doesn’t mean it is a good one.
