Milk protein isolate is a protein supplement extracted from skim milk. You can find it on the ingredient list of different protein supplements, such as a protein bar. Food manufacturers consider it a cost-effective solution to boost protein content without affecting the flavour. It is different from a common milk protein diet, like butter milk protein. Milk protein isolate contains whey proteins and casein in a ratio similar to their ratio in cow’s milk, i.e. 80% casein to 20% whey. Read on to learn more about this supplement, its health benefits and potential downsides.
What is milk protein isolate?
Milk protein isolate is a protein extract derived from skim milk. Manufacturers derive it by applying filtering processes which include microfiltration, diafiltration, and ultrafiltration. These processes remove a high value of minerals and lactose. After these, a powder with about 90% protein content is produced. Due to its high casein content, it takes a long time to digest. However, if you take only the whey protein part, it will get absorbed in your body rapidly, boosting the amino acid levels. Remember that the preparation of milk protein isolate differs from casein powder and whey powder.Additional Read: World Vegetarian Day: 6 Top Protein-Rich Foods You Should Include in Your Diet
Key health benefits of milk protein isolate
Milk protein isolate has a number of health benefits. Here’s a look at them.
It leads to a slower and better digestion
When it comes to digesting casein protein-based milk protein, it takes additional time for your body due to the protein’s firmness and changing texture. As a result, your body releases the amino acids slowly and steadily. That’s why it is wise to consume milk protein before going to sleep, as your body will get a constant supply of amino acids while you are not eating for 7-8 hours.
It helps you develop muscle mass
As milk protein isolate has sufficient protein and amino acids, it plays a key role in developing muscle mass. The compound has all nine essential amino acids, which your body cannot produce on its own. Among them, leucine plays a crucial role in initiating muscle protein synthesis. A study conducted among 16 healthy middle-aged men discovered that milk protein boosts muscle development in a pattern resembling that of whey protein . Other studies also suggest that the muscle growth rate stimulated by milk protein is quicker than casein protein, and they continue for a longer period of time than whey protein .
It can help you to shed a few kilos
Milk protein isolate is loaded with protein; an essential nutrient your body needs to lose fats. By consuming more protein, you can contribute to the metabolism process and burn extra calories. Besides, milk protein isolate keeps you full for a longer time than other protein sources like whey. As a result, you eat less and do not put on weight.
It can promote bone growth
Research suggests that consuming milk-based protein on a regular basis can boost your bone density and prevent the decay of bones  .
It has immunity-boosting anti-inflammatory benefits
As per a review of multiple studies, regular consumption of dairy products has a notable anti-inflammatory impact on people. The participants in the studies either had health issues like metabolic syndrome, obesity and type 2 diabetes or didn’t have any at all .
Potential downsides of milk protein consumption
Though regular intake of milk protein isolate has major benefits, it can cause health issues in people suffering from certain conditions. If one is allergic to cow milk protein, they shouldn’t consume milk protein isolate. Having too much milk protein isolate in your stomach may lead to digestive issues such as flatulence, bloating, nausea, and cramping. Though it has a relatively low amount of lactose, people suffering from lactose intolerance may have uncomfortable side effects while consuming milk protein isolate. Apart from this, the availability of milk protein isolate is a major issue, so you may not find it easily in the market.
