Is whey protein isolate good for you?

Whey is a complete source of protein compared to any other source of vegetable proteins or any protein from animals and there are three types of whey. That is why Whey protein is the most common form of protein powder. As all requirements of amino acids can be completed through whey it is called a complete protein.If you are doing resistance training then your protein requirements increase. 

The best alternative, your diet of protein-rich foods should be able to suffice your requirements. But when increases in protein requirement have to be supplemented then you have to be aware of your lactose tolerance. 60% of the world's adults are lactose intolerant.  These adults prefer Whey protein isolate or some other plant-based protein. 

Based on processing techniques protein is divided into three forms of whey: Hydrolysate, Concentrate, and Isolate. Their processing steps and purifying process differentiate the three. Each form of Whey has its own properties, advantages, and drawbacks. Whey protein isolate is a type of whey protein refined to extract much of the fats and carbohydrates. (source: Wikipedia) This product is relatively new to the dietary supplements industry.

By the method of isolating protein from whey, the whey protein isolate is prepared. It contains 90 percent protein content and is a healthy source of one of the anabolic essential amino acids, leucine. By filtering or centrifuging the liquid that is leftover from cheese making, whey isolate is made.

Isolate is a type of protein that is used in muscle building and muscle fiber development. Protein intakes in this form are favored by bodybuilders since this high-quality protein is the purest form. It is used around the world by runners, bodybuilders, weight lifters, and other exercise enthusiasts. Some health enthusiasts say their performance during workouts is also better by consuming Whey Protein Isolate though I personally don't feel so. 

What is the side effect of whey protein isolate?

Whey protein isolate is a protein from milk that is refined to extract lactose content and fat. Milk protein is called a complete protein because it contains all the necessary muscle-building amino acids. Isolate is a more processed form that can lack any of the other normal milk nutrients.Although it is usually thought to be healthy for your health to increase protein consumption, eating so much whey protein can contribute to some unexpected side effects. To read more about side effects, please check out the following detailed article about whey.

Whey Protein Isolate vs Concentrate

The difference between Whey Concentrate and Isolate is that of lactose levels. Whey Protein Concentrate has high levels of lactose i.e., 3 to 3.5%. Processing of Whey Concentrate by further filtering processes leads to Isolate. 

Looking at nutritional differences Concentrate has more carbs, fats, and certain vitamins and minerals.  Isolate has almost nil Carbs, Fats, and any other minerals and vitamins. 

Concentrate vs Isolate

So the key factor i.e. protein quantity is about 90% in Isolate whereas it is a maximum of 80% in concentrate. To increase your daily protein intake you can either have Isolate or increase your concentrate intake. 

There are not many positive effects of this except for the weight loss industry. In terms of health benefits, there are more calories in concentrate and less in isolate. As it is digested faster than Concentrate the food cravings are also decreased

Most of the health enthusiasts who do whey protein supplementation prefer concentrate as it is less expensive.

Fake or Spurious Products

Due to its beneficial effects, though it is expensive, it is very popular among fitness enthusiasts. Due to the high demand and huge margins available in manufacturing spurious products, a lot of those products are available in the market.  This is prevalent in the food industry in spite of the fact that spurious food products are a potential risk to the consumer's health.

Be very cautious and alert when buying one. Fakes can easily be recognized if we look closely. The packaging can never match the original product. To counter this, their manufacturing date is also very old, usually close to expiry. This is to explain to the consumer that the packaging looks old as it actually is old. So more discount is also offered on it. Companies also have various ways to authenticate the product.

The best way is to check with the retailer how he can prove that the product is original. He knows how to prove if it is original. For online purchases buy from a reputed retailer who is concerned about his reputation and check the product packaging before opening it. Send it back to the retailer if you are unsure. I even emailed the packaging image of a Muscletech Product to the manufacturer in Canada. They replied within 24 hours that it is genuine.

Hydrolysed Whey Protein Isolate

Whey Protein Hydrolysate is whey protein isolate powder in pre-digested form.  By further processing whey protein, by heating it or treating it to acids or enzymes, whey protein hydrolysate is formed. It has the smallest chain of amino acids.

It is usually prescribed to patients who have protein digestibility problems. It is said to give the fastest recovery from intense workouts and does the fastest muscle protein synthesis.

As it is treated to such an extent sometimes consuming it is not considered so healthy as there is no other nutrient in it except protein.  This can create an imbalance of nutrients in the body. It is much more costly as compared to the other two types of protein.

Grass-Fed Whey Protein Isolate

This is one of the sources of protein. It is important to understand this protein in relation to Whey Protein Isolate.  Grass-fed whey protein as the name suggests is obtained from grass-fed cow's milk only.

Such cows are raised only on grass feeds. But this is not regulated by FDA so it is difficult to assume that it is entirely true. 

The difference in the product is in terms of fat. Grass-fed cow's milk contains more healthy fats and vitamins like A & E along with glutathione.  Specifically, it contains Omega-3 fatty acids. There is little or no increase in protein value or decrease in carbohydrates in the grass-fed cow's milk.  Nor is there any increase in its Amino acid score. 

Now the interesting part is that during the processing of Protein Isolate mostly all carbs and fats are removed. So the healthy part or all the nutritional benefits of grass-fed cow's milk is actually removed before serving it to you.

Please also check reviews of the product that you plan to buy. All most all products will have good as well as bad reviews. But if the good reviews are more. Check the date of reviews. If the reviews are old, check a couple of more sites for the latest reviews. Some companies will add reviews by their customers in other countries where it might by supplying a similar but a slightly different product. Buy the product which has your country reviews as sometimes the product specifications also differ from country to country.

Conclusion

There are companies that don't give complete information on the packaging. They will give only the information deemed mandatory by the government. Then there are others who will not respond whether the product we purchased is original or spurious. That is irresponsible behaviour towards the consumer.

Though I keep changing and checking my protein powder, my favourite is still the Optimum Nutrition Platinum Hydrowhey Protein Powder. It has unbeatable quality and taste. The company is very open about the product it offers and you can get complete information on the packaging. You get immediate replies to any queries raised.
