Optimum Nutrition Whey Protein

What is Whey Protein?

Whey is a Dairy Protein derived from cow’s milk. Cow’s milk is made up of approximately 88% water and variable amounts of the three macronutrients: Carbohydrates (≈5%), Fat (≈4%) and Protein (≈3%). The Protein found in milk contains two types of Protein, Whey and Casein. Casein (sometimes call “Cheese Protein” as it forms the basis of the solid curds which become cheese) is the most abundant Protein in milk comprising about 80% of the total protein content. Whey is the less abundant of the two Milk Proteins making up about 20% of the total Protein.

Are whey protein safe?

Whey Protein is generally safe for consumption by healthy adults.Consumption needs for individuals may vary depending on weight, health condition and physical activity. It is a high-quality complete protein source derived from milk, containing essential amino acids. However, individuals with lactose intolerance should be cautious due to the presence of some lactose* in whey protein.

* Whey protein isolate, which is processed to remove most of the lactose, is generally considered safe for individuals with lactose intolerance. It is always advised to check the label for "Lactose-Free" claim. In general, in case of food intolerances, allergies or any medical conditions always check with your healthcare professional first.

What are the types of Whey Protein ?

There are 3 types of Whey Protein : Whey Protein Concentrate (WPC), Whey Protein Isolate (WPI) & Hydrolyzed Whey Protein (WPH)

Which whey protein is best?

Supplement companies offer a variety of whey proteins, making it challenging to choose the right one for your goals. Whey Protein Concentrate (WPC) is a popular option, though it has slightly more calories, carbohydrates, and fat per serving. For those seeking lower fat, cholesterol, and carbohydrates, Whey Protein Isolate (WPI) is a suitable choice. Hydrolyzed Whey Protein, which is either isolate or concentrate broken down into smaller pieces, allows for quicker absorption of proteins and amino acids. Some supplements combine these types to balance flavor, macronutrients, and benefits. Check the "Nutrition or Supplement Facts Label" for specifics to find the best whey protein for your personal needs, as whey protein supplements can help meet your daily protein requirements.

What is the Amino Acid Profile of Whey Protein ?

Amino Acid profile means content and distribution of the different amino acids found in a protein. It does not change from brand to brand, or region to region, as the protein source itself (in present case-Whey) has a standard amino acids profile. Only case the profile may change is if the manufacturers are "Adding" or "Enriching" the product with added amino acids. Product label is a limited space so manufacturers chose to remove individual amino acids distribution since it is essentially a common knowledge that can be found anywhere in public domain.
