About

Garlic contains organosulfur compounds (allicin, diallyl disulfide) that stimulate macrophage, lymphocyte, and NK cell activity, modulate cytokine secretion, and exhibit broad-spectrum antimicrobial activity. A 12-week RCT showed the garlic group had significantly fewer colds and shorter symptom duration.

How It Works

Organosulfur compounds (allicin, diallyl disulfide) stimulate macrophage, lymphocyte, and NK cell activity; modulate cytokine secretion; exhibit broad-spectrum antimicrobial activity via S-thioallylation of protein thiols.
