Garlic

Garlic

Garlic's activity comes from sulfur compounds that alliinase turns from alliin, used for blood lipids, blood pressure, and seasonal upper-respiratory circulatory nutrition.

Primary

Helps blood-lipid metabolism

Sulfur compounds can affect hepatic cholesterol synthesis and blood-lipid oxidation markers, so human trials watch changes related to total cholesterol and triglycerides. People whose diet runs oily and whose fasting lipids run high more often see a difference in labs and a lighter body feel after several continuous weeks.

Primary

Supports blood-pressure–related circulation

Garlic sulfur compounds can also promote endothelial nitric-oxide–related signaling; vasodilation and blood-pressure markers are often recorded together in trials. People attending to morning blood pressure, a heavy head, and tinnitus more often see change in measurements and a clearer head after several continuous weeks.

Primary

Helps seasonal upper-respiratory defense

Allicin and related sulfur compounds in some trials watch cold occurrence and symptom days; mucosal-immunity and antimicrobial felt effects land in the season-change stretch. People whose throat itches first every autumn and winter more often see a difference in fewer minor ailments and course length after several continuous weeks.
