Why consider protein supplementation?

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 recommendations3. Individuals undergoing cancer treatment often have diminished appetites, which can make increasing protein intake to meet these increased recommendations very challenging.

 

Many health conditions and life stages require daily protein intakes far above the typical daily requirement:

Condition

Increased Protein Requirement (compared to the RDA)

Aging

25-50% more

High activity

75-150% more

Weight loss

50-100% more

Burn recovery

90-150% more

Cancer treatment

25-90% more

Wound healing

50-150% more

Hepatitis

50-90% more

Renal replacement therapy

90% more

 

Why choose whey protein?

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.

Whey protein is a high-quality, highly bioavailable protein that is isolated from milk. It is filtered to remove much of the fat, lactose, minerals, and water then dried to make whey protein powder. It contains all nine of the essential amino acids in sufficient quantities to support muscle protein synthesis

Whey has has a biological value of 1044, a measure reflecting the proportion of dietary protein retained in the body for growth and/or maintenance. Whey’s biological value is higher than other common proteins like soy (74), milk (91), or beef (80).
