Tag: Peptide bioavailability

Peptides are short chains of amino acids, and recent research indicates their efficacy is highly dependent on how they are administered. The question of whether ingesting peptides works hinges on how these delicate molecules survive the harsh journey through the digestive system.

Over 95% of therapeutic peptides have historically been administered via injection, largely because the delicate amino acid chains are easily destroyed by the digestive system. However, asking "are peptides oral or injectable?" reveals a complex landscape, as significant research and new formulations are enabling oral delivery for some peptides.

According to extensive research, peptides are indeed absorbed by the body, with smaller ones being absorbed more readily than larger proteins. The methods and efficiency of how the body can absorb peptides, however, vary significantly depending on whether they are ingested or applied topically.
