Cholesterol reduction (as part of plant sterol blend)

Strong Evidence

Effects are demonstrated for plant sterol blends; isolated campesterol has not been individually trialed in major outcomes.

How it works

Like beta-sitosterol, campesterol competes with cholesterol for absorption in the intestine, lowering serum LDL. Plant sterol products are typically a blend dominated by beta-sitosterol with smaller amounts of campesterol and stigmasterol. Campesterol is more readily absorbed than beta-sitosterol, which raises both its potential utility and its slight relevance in sitosterolemia.

Dosage

No RDA for isolated campesterol. Plant sterol blends targeting cholesterol use 1.5-3 g/day total.

When and how to take it

WHEN: With meals containing fat. HOW: Take with the largest meal.

Plant sterol blend (with beta-sitosterol, stigmasterol)

The practical commercial form.

Campesterol more absorbed than beta-sitosterol.

Safety

Generally well tolerated as part of plant sterol blends. May reduce fat-soluble vitamin and carotenoid absorption. Contraindicated in sitosterolemia.

Who should be cautious

Avoid in sitosterolemia. Caution in pregnancy due to limited isolated-compound data.

Interactions

May reduce absorption of fat-soluble vitamins; mild additive effect with ezetimibe.
