Dietary fiber and probiotic-induced short-chain fatty acids (SCFAs) reduce blood pressure and improve vascular health through G-protein coupled receptor signaling and histone deacetylase inhibition.

Increase your intake of dietary fiber and consider probiotics to boost short-chain fatty acid production. This metabolic shift activates specific receptors (GPR41/43) and enzymes that help lower blood pressure and improve vascular function. Focus on non-starch polysaccharides and low-digestible saccharides found in whole plant foods.

GoodSupportsHIGH confidence
Results from two independent meta-analyses of randomized-controlled trials suggested that increased SCFA induced by probiotics or dietary fiber intake was associated with a reduction in blood pressure in patients with hypertension... Intra-venous administration of propionate in vivo in mice lowered blood pressure... Repeated intraperitoneal injections of butyrate in mice chronically infused with angiotensin II were able to significantly reduce blood pressure.

Why this rating

Supported by multiple meta-analyses of RCTs in humans and consistent animal models, though specific human dosing protocols vary.
