Whey Protein Isolate

The dietary protein provided by Whey Protein Isolate supplies essential amino acids that participate in all of the bodys metabolic and physiologic systems including the intestine, skeletal muscle, and the cardiovascular, nervous, and immune systems. Protein turnover in these systems is continuous and can be substantial. The dynamics of this constant degradation and resynthesis demand a daily supply of dietary protein and their constituent amino acids. Essential or indispensable dietary amino acids must be supplied by the diet as they are not made de novo by the body.

Recent analyses of the dietary protein needs of people suggest that age and activity level may influence protein requirement for optimum health. For example, elderly adults may have a significantly higher protein requirement than that of young adults. This requirement may be as high as 1.0 g protein per kg body weight per day, or 25% more than that suggested for a young adult. This higher requirement may derive from a lower efficiency of protein utilization in advancing age, despite the associated decrease in muscle mass. Failure to meet these increased protein needs may negatively affect an individuals immuno-competence and recovery from medical complications.

Some scientists have also suggested that increased protein synthesis follows prolonged exercise. Athletes competing in body building or endurance sports may require significantly more protein that the normal requirement

Serving Size: 1 scoop 20 gms
Servings Per Container: 12

Active Ingredients:

• Calories 74
• Cholesterol 5 mg
• Total Carbohydrate 3 g
• Sugars (as fructose) 3 g
• Protein 15.5 g
• Whey Protein Isolate 17 g

Inactive Ingredients: Fructose

Recommended Dosage:
As a dietary supplement, adults mix 1 scoop with 10-12 oz water or other beverage daily or as directed by physician. Please mix vigorously until protein is dissolved. Due to nondenatured, non-instantized nature of this whey protein isolate, it may take a full 1-2 minutes to dissolve.

Whey Protein Isolate may be a useful dietary supplement for individuals who wish to increase their intake of protein.

Store in a cool, dry place, away from direct light. Keep out of reach of children.
