Beta-Sitosterol (Plant Sterols)
Phytosterol
Beta-sitosterol is a plant-derived sterol structurally similar to cholesterol. It competes with dietary cholesterol for absorption in the intestines, effectively blocking cholesterol uptake into the bloodstream. It is one of the most clinically studied natural compounds for cardiovascular and immune health.
How It Works
Plant sterols sit in the same absorption receptors as dietary cholesterol in the small intestine. By occupying these receptors, beta-sitosterol reduces how much cholesterol enters your bloodstream. It also modulates immune function by regulating T-helper cell activity, which can help balance overactive immune responses such as allergies.
