Egg White

Q: When should I take egg white protein?

It is ideal to consume after exercise and before bedtime to support muscle recovery and growth.

Q: What is the recommended dosage?

Aim for 20-25 grams per serving, totaling 1.6-2.2 grams per kg of body weight daily.

Q: Is it safe for everyone?

While generally safe, individuals with egg allergies should avoid egg white protein.

Q: What results can I expect?

Consistent use over several weeks may lead to increased muscle mass and strength.

Q: Are there any misconceptions?

Some believe egg white protein is superior to all other protein sources; while it's high-quality, alternatives like whey and casein also offer unique benefits.

Also known as: egg albumen, albumen protein, ovalbumin, ovotransferrin, ovomucoid, ovomucin, lysozyme, Egg White Protein

Overview

Egg white protein, derived from the albumen of eggs, is primarily composed of proteins such as ovalbumin, ovotransferrin, ovomucoid, ovomucin, and lysozyme. It is recognized for its high-quality, complete amino acid profile, making it beneficial for muscle protein synthesis, particularly in the context of resistance training and athletic performance. Research on egg white protein is well-established and includes numerous systematic reviews and meta-analyses evaluating its impact on muscle mass and overall health. It is commonly used in dietary supplementation for individuals looking to enhance strength and muscle gains during resistance training. Available in various forms including powders and hydrolysates, egg white protein can effectively support dietary protein needs and recovery.

Benefits

Egg white protein supplementation is associated with several significant benefits. Systematic reviews indicate it can enhance muscle mass and strength, particularly during resistance training, with a notable increase in fat-free mass and strength measurements. For example, a meta-analysis reported a mean difference of 0.30 kg in fat-free mass and an increase in one-repetition maximum strength (SMD of 0.20) when compared to placebo. It is especially beneficial for healthy adults aiming to gain lean body mass. While some studies show alterations in serum free amino acid concentrations, these did not consistently correlate to improved body composition or strength. Overall, the evidence is robust, characterized by high-quality studies substantiating these benefits.

How it works

Egg white protein functions primarily by supplying essential amino acids, which are critical in stimulating muscle protein synthesis (MPS). Particularly, amino acids like leucine play a pivotal role in activating the mTOR pathway, a key regulator of MPS. Upon ingestion, egg white protein is rapidly absorbed into the bloodstream, supplying the necessary building blocks for muscle repair and growth, thus aiding recovery post-exercise and promoting hypertrophy.

Side effects

Egg white protein is generally safe for consumption, with adverse effects being rare. Common side effects (>5%) are not notably reported, although some individuals may experience gastrointestinal discomfort, such as bloating or stomach cramps, tied to protein supplementation in general. Allergic reactions are infrequently noted (<1%), primarily in those with egg allergies, specifically linked to the protein ovomucoid. There are no significant reported drug interactions; however, individuals with egg allergies should avoid egg white protein entirely. Precautions should also be considered for pregnant or breastfeeding women, who are advised to consult healthcare providers prior to supplementation.

Dosage

The minimum effective dose of egg white protein for supporting muscle protein synthesis generally ranges from 20-25 grams per serving, which should include approximately 2-3 grams of leucine. For individuals engaged in resistance training, a recommended daily intake is between 1.6-2.2 grams of protein per kilogram of body weight, ideally distributed across 3-5 meals. While no defined maximum safe limit exists, excessive protein intake beyond 3 grams/kg/day may not deliver extra benefits and could elevate renal strain. Consuming egg white protein post-exercise is optimal, within a 1-2 hour timeframe to facilitate recovery and muscle gain. The protein can be ingested as powders, hydrolysates, or whole egg whites, with hydrolysates providing potentially faster absorption.
