Whey protein isolate is a dietary supplement and food ingredient created by separating components from milk. Whey is a by-product of the cheese-making process, and whey protein isolate is produced by filtering whey to remove the fat and lactose, resulting in a product that's over 90% protein. This makes it one of the purest forms of whey protein available. It's popular among athletes, bodybuilders, and those looking for a high-quality source of protein to support muscle growth and repair.

Nutritional Profile (per 100 grams):

• Calories: Approximately 360 kcal
• Protein: Typically around 90 grams, making it extremely high in protein.
• Fat: Very low fat content, often less than 1 gram.
• Carbohydrates: Low in carbohydrates, mostly lactose, which is significantly reduced in isolate form, often less than 1 gram.
• Lactose: Minimal lactose content, making it suitable for individuals who are lactose intolerant.
• Vitamins and Minerals: Contains calcium and is often fortified with additional vitamins and minerals.

Whey protein isolate is particularly noted for its high protein content and rapid absorption rate, making it a preferred choice for post-workout recovery. It helps in muscle protein synthesis and provides a quick source of amino acids to the muscles.

Considerations

Digestibility: Generally well tolerated and easily digested, especially by those who have lactose intolerance or sensitivities to dairy products.

Usage: Can be incorporated into shakes, smoothies, and various recipes to increase protein intake without significantly adding to fat or carbohydrate content.

Allergies: Individuals with a milk allergy should avoid whey protein isolate, as it is derived from milk.
