Evidence supporting the use of: Peptide (bonito)
For the health condition: Circulation (poor)
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Peptide (bonito), specifically referring to peptides derived from bonito fish (a species of tuna), has been investigated for its effects on circulation, particularly in relation to blood pressure and vascular health. Scientific studies, mostly from Japan, have demonstrated that certain bonito-derived peptides can act as ACE (angiotensin-converting enzyme) inhibitors, which may help to lower blood pressure and improve endothelial function. A number of clinical trials have evaluated bonito peptide supplementation (often in the form of hydrolyzed bonito extract) and reported modest but statistically significant reductions in systolic and diastolic blood pressure in people with mild hypertension or prehypertension.
The mechanism of action is similar to pharmaceutical ACE inhibitors, where inhibition of this enzyme leads to vasodilation and improved blood flow. These effects may support overall circulation, though the magnitude of benefit is generally less than that of prescription medications. Some studies also suggest potential improvements in markers of arterial stiffness and blood vessel function, but evidence for broader circulatory benefits beyond blood pressure is limited.
Overall, while the evidence base is not extremely large or robust (hence the rating of 3), there is scientific validation from controlled trials and mechanistic studies supporting the use of bonito peptides for improving aspects of poor circulation related to hypertension. However, more high-quality, large-scale studies are needed to better define the clinical significance and safety profile of long-term use.
