About this supplement

Peptides are short chains of amino acids linked by peptide bonds, typically containing 2-50 amino acids. They are intermediate in size between single amino acids and full proteins. In dietary supplements and beauty products, peptides are valued for their bioactive properties, including signaling cellular functions, providing structural support, and acting as antioxidants. Specific peptide sequences can target various physiological processes such as collagen synthesis, muscle repair, skin hydration, and immune modulation. Hydrolyzed peptides (like whey isolate peptides) are pre-digested for enhanced absorption. Their function is highly sequence-dependent.

How much to take

Typical amount
Oral: 1-20g daily for protein/muscle support; Topical: 1-10% in formulations; Specific peptides have precise dosage ranges.
Suggested range
Varies drastically by peptide type and purpose. General hydrolyzed peptides: 5-20g daily orally. Specific bioactive peptides (e.g., collagen peptides): 2.5-15g daily. Topical: 0.5-5% concentration.

Physical properties

Varies widely by specific peptide. Typically white to off-white powders. Solubility depends on amino acid composition (hydrophilic vs. hydrophobic). Often hygroscopic. Molecular weight ranges from ~200 Da (dipeptides) to several thousand Da (polypeptides).

How it’s made

Produced via enzymatic hydrolysis of proteins (e.g., whey, collagen, soy) to break them into smaller peptides. Also synthesized via solid-phase peptide synthesis (SPPS) for specific sequences. Fermentation using recombinant microorganisms is another method. Hydrolyzed forms undergo filtration and purification.
