Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Egg white protein is sometimes used to support energy levels, but the scientific validation for its direct role in treating or preventing "lack of energy" is modest. Egg white is a high-quality protein source, containing all essential amino acids and being low in fat and carbohydrates. Protein is essential for muscle maintenance and repair, and consuming adequate protein can help prevent fatigue related to muscle breakdown, especially in individuals with increased physical demands or those who are protein deficient. Some studies suggest that protein intake, including from egg white, can help maintain muscle mass and support recovery in athletes, which may indirectly support feelings of energy by reducing fatigue from exercise-induced muscle damage. However, there is little direct evidence that egg white protein specifically increases energy levels in healthy individuals beyond its general nutritional value as a protein source. Most scientific support relates to overall protein’s role in satiety, muscle health, and recovery rather than a direct effect on energy or fatigue. Thus, while egg white protein is a valuable component of a balanced diet, its use for specifically treating or supporting "lack of energy" is not strongly supported by targeted clinical research.
