What are Peptides and their Role in the Body?

Peptides are found in all cells and tissues and help sustain health. These "tiny proteins" can send messages to the brain and facilitate intercellular communication, directing various functions.

Humans have around 7,000 peptides, which govern many vital biological functions. Among their diverse functions are the following:

  • Facilitate the transmission of signals between nerve cells in the brain and throughout the body.

  • Bind to specific receptors on target cells and initiate signaling pathways that regulate various physiological processes.

  • Support weight loss, muscle mass, sexual function, and immunity.

  • improve the skin barrier and help produce collagen and elastin for healthy skin.

Meanwhile, the natural production of peptides can vary significantly among individuals, with a decline occurring as a person ages. This is where peptide therapy becomes valuable, as it involves using synthetic peptides to compensate for the decrease in natural production.

What is Peptide Therapy?

Peptide treatment uses peptides from animal or plant protein sources to replenish or change peptide levels in the body, improving health.

The versatility of peptide treatment allows it to cater to a wide range of health concerns and goals. The selection of each peptide used in therapy is based on clinical research and chosen for its specific ability to trigger a desired biological function within your body.
