Egg protein

Protein

What is it

Egg protein supplements are made primarily from dried egg whites. They provide a complete protein with high biological value, are lactose-free, and contain all essential amino acids in proportions favorable for muscle protein synthesis.

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Muscle protein synthesis / lean mass

Strong Evidence

Egg protein consistently supports muscle protein synthesis and lean mass when combined with resistance training. Studies confirm efficacy comparable to other high-quality animal proteins.

Satiety / weight management

Good Evidence

Egg-based meals and protein shakes increase satiety and may modestly support weight management compared with lower-protein options.

How it works

Egg white protein is rich in essential amino acids, particularly leucine, which is a potent trigger of muscle protein synthesis via the mTOR pathway. Egg protein digests at a moderate rate - faster than casein but slower than whey - producing a sustained rise in plasma amino acids. Egg white protein has historically been the reference standard for protein quality and scores highly on the Protein Digestibility-Corrected Amino Acid Score (PDCAAS) at 1.0. It supports muscle maintenance and growth, satiety, and recovery from exercise.

Dosage

There is no specific RDA for egg protein. General adult protein recommendation is 0.8 g/kg/day, with active individuals often consuming 1.2-2.0 g/kg. Typical egg protein supplement servings provide 20-25 grams of protein. DSLD label data did not include a typical dose.

When and how to take it

WHEN: Around exercise (within 1-2 hours before or after), as a between-meal protein source, or as a slower-digesting alternative to whey. HOW: Mix with water or milk; combine with carbohydrates after intense training.

3 commercial forms

Compare the main delivery options and what they’re best suited for.

Egg white protein powder

The standard form; little fat or cholesterol.

High PDCAAS; complete amino acid profile.

Hydrolyzed egg white protein

Used in some sports formulations.

Pre-broken peptides; faster absorption.

Whole egg protein

Less common; provides more micronutrients.

Includes yolk; contains fat and cholesterol.

Safety

Generally safe at typical intakes. Egg allergy is one of the most common food allergies, particularly in children - those with egg allergy must avoid these supplements. Excess protein from any source may strain kidneys in people with pre-existing kidney disease.

Who should be cautious

People with egg allergy must avoid. People with chronic kidney disease should consult a clinician about protein intake. Otherwise safe in pregnancy and lactation at normal dietary amounts.

Interactions

Like other dietary proteins, can slightly reduce levodopa absorption when consumed at the same time. No other major interactions.

Frequently asked questions

Is egg protein better than whey?⌄

Both are high-quality proteins. Whey digests faster and has a slightly higher leucine content. Egg protein digests moderately and is lactose-free. Choose based on personal tolerance and goals.

Does egg protein raise cholesterol?⌄

Egg white protein powders contain essentially no cholesterol (cholesterol is in the yolk). Whole egg powders contain some cholesterol but dietary cholesterol has a modest effect on blood cholesterol for most people.
