Cardiovascular
This category currently covers aged garlic extract, which has a reasonable body of human trial evidence for modest blood pressure and cholesterol effects — one of the better-supported single-ingredient cardiovascular interventions on the site. It's a small category for now; more cardiovascular-specific reviews are planned.

Common questions
Which cardiovascular supplement has the strongest evidence for lowering cholesterol?
Plant Sterols & Stanols is the strongest option here for cholesterol — grade B overall, but rated grade A specifically for LDL-lowering. A dose-response meta-analysis of 124 randomized trials shows it reliably drops LDL cholesterol 7-12% at 1.5-3 g/day by blocking cholesterol absorption in the gut, one of the most consistent effects in supplement research. Aged Garlic Extract (grade B) also lowers cholesterol, but more modestly: a 39-trial meta-analysis found roughly a 17 mg/dL drop in total cholesterol and 9 mg/dL in LDL, and only after more than two months of use. The honest catch: for plant sterols, no randomized trial has ever tested it against hard outcomes like heart attack, stroke, or cardiovascular death — the FDA/EU heart-disease-risk claim rests entirely on LDL as a validated surrogate marker. Aged garlic's cholesterol and blood-pressure improvements are likewise surrogate markers; its lower coronary-event risk is inferred from population studies, not demonstrated directly. So the LDL-lowering is well established for both, but the heart-attack-prevention piece is an inference from cholesterol changes rather than a direct finding.
Can these supplements replace my statin or blood pressure medication?
No — both are graded B and positioned as complements, not substitutes. Plant Sterols & Stanols were studied alongside statins and added only about 11-12 mg/dL of extra LDL reduction on top of the drug, and they combine safely with it. Aged Garlic Extract lowered systolic blood pressure roughly 7-9 mmHg in people who were already hypertensive (little effect in those with normal pressure), which is real but still a supporting player next to prescribed therapy — and it can compound the effect of blood thinners and blood-pressure drugs, so a clinician conversation matters if you're on medication.
