Beta-sitosterol is probably safe for most people when taken in normal amounts, such as amounts found in food, but higher doses could cause problems. Some people may be more likely to experience problems than others. Therefore, you should talk with your healthcare provider prior to taking it if you have:
- A vitamin deficiency due to malabsorption digestive problems
- Sitosterolemia (phytosterolaemia), a rare genetic condition
- Any allergies, including allergies to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant (see Beta-Sitosterol and Pregnancy)
- Breastfeeding (see Beta-Sitosterol and Breastfeeding).
Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.

It is not known exactly what to expect from an overdose, or even if an overdose is possible, but it is reasonable to assume that taking too much may cause the usual side effects of beta-sitosterol, but perhaps more severely.

Refer to the label of your individual beta-sitosterol product for information on how to best store it. Keep beta-sitosterol and all medications and supplements out of the reach of children.
