Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Egg protein is scientifically recognized as a high-quality, complete protein source containing all essential amino acids in proportions optimal for human nutrition. It is highly digestible, with a Protein Digestibility Corrected Amino Acid Score (PDCAAS) of 1.0, which is the highest possible rating. Scientific literature supports the use of egg protein to supplement dietary protein intake in individuals with poor protein digestion or absorption, such as the elderly, athletes during recovery, or those with certain gastrointestinal conditions. Egg white proteins, primarily ovalbumin, are readily broken down and absorbed in the small intestine. Research in clinical nutrition indicates that egg protein supplementation can improve protein status and support muscle maintenance in populations at risk of malnutrition or poor protein utilization.

However, egg protein itself does not directly treat underlying causes of poor protein digestion (such as pancreatic insufficiency or severe gastrointestinal disorders), but rather provides a highly digestible protein source that can be more easily utilized by individuals with compromised digestive function. There is less evidence to suggest it improves the digestion process itself, but strong support exists for its use as an alternative protein source in those who may struggle with other less digestible proteins, such as some plant proteins or certain dairy proteins. Thus, scientific justification exists for its use as a nutritional intervention to support protein needs in cases of poor digestion, though it is not a cure for the underlying digestive impairment.
