Atrial Natriuretic Peptide

Atrial Natriuretic Peptide (ANP) is a hormone secreted by atrial cardiomyocytes in response to increased blood volume. It plays a key role in regulating blood pressure, blood volume, and sodium and water balance.

In the literature, Atrial Natriuretic Peptide appears most often in work focused on heart health and metabolism. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

Atrial Natriuretic Peptide is catalogued here under powder peptides. Coverage of this compound varies in quality and depth, and much of it remains early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
