This site's own FAQ addresses this directly: potential side effects depend on the ingredients and the individual. Review your current label and consult a healthcare professional if you have concerns.
Worth reading this answer's generality as a direct consequence of this site's own central admission — it cannot name specific side effects for ingredients it could not fully confirm in the first place.
Review your own current label directly for any listed caution or warning, and consult a healthcare professional if you have any specific concern, per this site's own direct recommendation.
