It can be difficult for some people to eat enough whole foods to meet dietary protein needs, especially in the face of calorie constraints, inappetence, and/or increased protein requirements. According to the Academy of Nutrition and Dietetics, European Society for Clinical Nutrition and Metabolism1, and the International Society for Sports Nutrition2, protein needs can range from 25%-150% higher than typical requirements across a range of health conditions, age and activity status.

For example, cancer patients undergoing chemotherapy or radiation therapy need up to 90% more protein than the recommended daily allowance to help reduce the risk of sarcopenia or help manage cachexia. A study by Stobäus et al found that 66% of cancer patients in the study had protein intakes below these recommendations.3 Individuals undergoing cancer treatment often have diminished appetites, which can make increasing protein intake to meet these increased recommendations very challenging. 

Many conditions require daily protein intakes far above the typical daily requirement of 0.8 grams per kilogram of body weight per day

When getting enough protein from food is a challenge, protein supplements offer simple, flexible, convenient, and cost-effective means to add high-quality, complete proteins to help bridge the protein gap. 
Not all proteins are the same

Whey is a high-quality, highly bioavailable protein that contains all nine of the essential amino acids in sufficient quantities to support muscle protein synthesis.
