phytosterol supplement side effects

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.
