High-quality protein intake

Strong Evidence

Albumins (especially egg ovalbumin) provide complete amino acid profiles supporting muscle protein synthesis.

How it works

Albumins are high-quality proteins providing essential amino acids. Egg albumin (ovalbumin) is widely used as a protein source. Bovine serum albumin and plasma protein concentrates are used in some specialized supplements and animal nutrition. Once digested, all albumins are broken down to amino acids that support muscle, immune, and metabolic functions.

Dosage

Protein supplements with albumin typically provide 20-25 g protein per serving. Adult protein RDA is 0.8 g/kg/day; many active individuals target more.

When and how to take it

Distribute protein across meals; often consumed around exercise.
