Big effect
Resveratrol lowered diastolic blood pressure by 3.55 mmHg in type 2 diabetes patients — a clean signal from a meta-analysis, but the benefit hasn't been tested in healthy people.
This is one of the first rigorous summaries to pin a specific, moderate-sized drop in diastolic pressure on resveratrol, but because the effect was seen only in people with type 2 diabetes, it's too early to assume the same would happen for someone without that condition.
An umbrella review of randomized trials found that resveratrol supplementation reduced diastolic blood pressure by about 3.5 mmHg in patients with type 2 diabetes — a meaningful change for that group. However, the finding comes from a clinical population, not general healthy adults, so the results don't automatically apply to everyone who might be curious about resveratrol for blood pressure.
Where this fits in the evidence
This is among the first studies we've indexed on Resveratrol for Reduced Diastolic Blood Pressure — treat it as an early signal until more research accumulates.
