Milk actually contains two main types of protein: casein (80%) and whey (20%). Whey is found in the watery portion of milk. When cheese is produced, the fatty parts of the milk coagulate and the whey is separated from it as a byproduct.

Whey protein is considered a complete protein as it contains all 9 essential amino acids. It is low in lactose content. Whey protein is the water-soluble part of milk i.e.; when you open a yogurt tin the liquid floating on the container is whey. 


After being separated during cheese production, whey goes through various refining steps to become what people generally acknowledged as whey protein. It's important to read the ingredients list, as some products may have unhealthy additives like refined sugar.

You can't consume whey directly as it doesn't taste very good. For this reason, whey is available in different forms. 

2:Benefits of whey protein

It’s a high quality, well-absorbed source of protein that’s very useful for hitting targeted daily protein goals. Its benefits extend to the benefits of increased protein intake.

a:Athletic performance: Most research shows that taking whey protein in combination with strength training increases lean body mass, strength, and muscle size in healthy young adults.

b:Muscle Building: Whey protein is an excellent source of protein which will help in muscle growth. Strength training coupled with the consumption of protein supplements has been shown to be an effective.

c:Lowering BP: Whey proteins may lower blood pressure in people with elevated blood pressure. This is due to the bio active peptides called cytokines.

Reduce Inflammation: High doses of whey protein have been shown to reduce blood levels of C-reactive protein, indicating that it can help reduce inflammation.

Increase antioxidant defensesWhey protein supplementation may strengthen the body's antioxidant defenses by promoting the formation of glutathione

Helps to reduce cholesterol level: Long-term, high-dose whey protein supplementation may lower cholesterol levels. The evidence is very limited at this point.

Asthma: Whey protein could improve the immune response in children with asthma.

Not only this but it also protects against cancer, reduces symptoms of hepatitis, increases bone mineral density and improves immune function in HIV patients.

3:How can it be consumed?

When the liquid whey is collected as a by-product of cheese or yogurt production, the liquid can be dried to form whey concentrate powder that consists of up to 80% protein by weight. The remaining 20% of the whey concentrate powder contains carbohydrates and fats.

A whey isolate powder containing 90% or more protein by weight can be produced after different processing steps are performed. After that, we will be getting the whey protein that is available in the form of whey powder.

This whey protein can be taken as whey powder that goes well with milk or any smoothies. It is also attainable in protein bars. You can also have it raw but it doesn't taste good. 

Side effects of whey 

Whey protein is LIKELY SAFE for most children and adults when taken by mouth appropriately. High doses can cause some side effects such as

  • Thirst
  • Reduced appetite
  • Headache

Some people who are allergic to milk may be specifically allergic to whey. In moderate doses, whey protein does not typically cause any adverse events. Although they contain a lot of nutrients, the balance is heavily tipped towards protein.

4:Precautions and safety measures

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking whey protein if you are pregnant or breastfeeding. Stay on the safe side and avoid the use of it in excess amount.

Interaction with medicines: Whey protein may also interact with some medications. These supplements also reduce the effectiveness of these medicines. So it's better to consult your doctor before use.
