The evidence in words
Safety profile
Odor and GI upset; antiplatelet action adds bleeding risk with anticoagulants and around surgery.
Interactions to respect
Anticoagulants (warfarin) — Antiplatelet action — additive bleeding risk. · Blood-pressure medications — Additive blood-pressure lowering.
What Garlic is
Garlic supplements deliver allicin and related sulfur compounds; aged garlic extract is a common standardized form. It is one of the better-studied culinary cardiovascular botanicals.
The honest bottom line
A rare kitchen supplement with real cardiovascular data: modest blood-pressure and lipid benefits. Mind the bleeding interaction if you're on blood thinners.
