Egg White Protein Research
Mostly mechanism / observational
15 peer-reviewed studies
What the evidence says
Mostly mechanism / observational
Most Egg White Protein studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality randomised trials published 1978–2025 with a typical study size of 48 participants.
Based on 15 studies · 13 RCTs · 182 total participants

In plain English: Research on the effect of molecular modifications on the functional properties of egg white proteins is greatly promising.

It may become a novel method of protein modification in the food sector due to its abundant source, low cost, eco-friendliness.
This work presents a comprehensive review of supercritical fluid technologies, focussing on their application in the innovative area of supercritical fluid therapy, specifically examining the modification of egg white protein.
Although this technique offers several advantages, there are multiple issues to be taken forward which includes scalability, cost-effectiveness, safety considerations and regulatory aspects when applying commercially especially food and medical uses.
In plain English: However, increasing protein intake from 1.0 to 1.6 g/kg/day did not further enhance performance.

Results : The duration, energy expenditure, training load score, and cardio load of each training session increased from the beginning to the end of each training period by 2-11% ( p < 0.05).
The 1 RM of shoulder press and strength endurance of core muscles increased by 3-6% ( p < 0.001).
Protein supplementation did not affect any of these outcomes.
In plain English: Egg white protein supplementation has beneficial effects on some nutritional statuses other than phosphorus control without the side effects of niacin.

In this regard, albumin increased in egg white and egg white with niacin supplementation, while albumin did not change significantly in the niacin group.
Urea reduction ratio and Kt/V rose only in the egg-white group, while aspartate aminotransferase increased only in the niacin and control groups.
Conclusion Niacin decreases serum phosphorus concentration more than egg-white protein or a combined intervention.
In plain English: EAA contents of plant-based protein isolates such as oat (21%), lupin (21%), and wheat (22%) were lower than animal-based proteins (whey 43%, milk 39%, casein 34%, and egg 32%) and muscle protein (38%).
In plain English: Resistance training increased lean mass and decreased fat mass, but moderately higher egg-based protein intake did not further influence body-composition responses.
Iglay HB, Apolzan JW, Gerrard DE, et al. · J Nutr Health Aging (2009)
12-week resistance-training trial in 36 older adults at 0.9 vs 1.2 g/kg/day protein, higher intake from eggs
Lean mass rose and fat mass fell with training; total/LDL cholesterol decreased
Higher egg-based protein did not differentially enhance lean mass or fiber size at these intakes
In plain English: A high-protein egg-based breakfast produced greater overall satiety and reduced food intake at the subsequent meal compared with a low-protein cereal breakfast.
Bonnema AL, Altschwager DK, Thomas W, Slavin JL · Int J Food Sci Nutr (2016)
Randomized crossover trial in 48 healthy adults comparing egg-based breakfasts to a low-protein cereal breakfast
High-protein egg breakfast (30g) increased satiety and lowered postprandial glucose and later food intake
Supports egg protein's strong satiety and appetite-control effects
