Lowering elevated LDL cholesterol levels
+3 (Strong Evidence)

PRO

  • Phytosterols are plant derived substances that lower cholesterol by preventing LDL cholesterol absorption in the intestine.
  • Phytosterols lower both total and LDL cholesterol on average by about 10%.
  • Phytosterols have an excellent safety profile and relatively few side effects.
  • There is good evidence that combining phytosterols with the omega-3 DHA can lower LDL cholesterol while improving HDL (good) cholesterol levels and lowering triglycerides.

CON

  • Even though it reduces LDL cholesterol, there are no long term outcomes showing that it actually lowers the risk of cardiovascular disease.
  • Studies used phytosterols in margarine-like spreads, and it is not clear whether capsules containing phytosterols will have the same benefit.
  • The overall effect of phytosterols on cholesterol levels is mild and other therapies may be required to meet individual goals for reducing cholesterol levels.
  • Side effects may include mild bloating, diarrhea, or constipation.

* *ADVISORY* *
None.

DOSAGE:1-2 grams taken twice daily with meals.

CONCLUSION:We conclude that phytosterols are safe and effective product for lowering total and LDL cholesterol levels. Work with your medical provider to make sure that cholesterol levels meet your own unique targets based on your specific medical conditions.
