What are some side effects of chlorophyll supplements?

There is no solid evidence regarding the side effects of chlorophyll supplements, according to WebMD. Chlorophyll may cause certain people to develop a rash from sun exposure and might also aggravate the effects of sun exposure in products that indicate sun sensitivity as a side effect.

Chlorophyll supplements can lower blood sugar levels and interfere with the effects of diabetes medicines, notes WebMD. Patients taking medications on a regular basis and individuals on any other supplements should inform a doctor before taking chlorophyll supplements. The safety of chlorophyll on children, pregnant women and lactating mothers is not known. Some people use chlorophyll supplements for constipation, bad breath or to hasten the healing process. The benefits of these uses are, however, not confirmed.
