Chlorophyll is one type of phytochemical responsible for giving plants their pigments. The other two are the carotenoids (yellow, orange and red) and anthocyanins (red, blue and purple). These substances also contain nutrients that aid in various bodily processes, from converting energy into food to whisking free radicals from cells before they can cause damage.
Patients who take methotrexate shouldn't take liquid chlorophyll. Sources are mixed on using this supplement during pregnancy. While many authorities believe it is safe, others rightly note that it can increase gastrointestinal symptoms like vomiting. When in doubt, it's best to avoid it.
You should always talk to your doctor or a pharmacist before taking any supplement. One of the key reasons is to ensure it doesn’t interact with any medications you may be taking.
