Chlorophyll is a pigment in plants. It's what makes them look green. Chlorophyll has been a popular supplement since the 1960s. But so far, there's no clear proof that it has health benefits.
Why do people take chlorophyll?
We have very little research about chlorophyll as a treatment.
"Chlorophyllin" is a different supplement. It comes from chlorophyll but doesn't have the same effects.
There's no standard dose for chlorophyll. Ask your doctor for advice.
Can you get chlorophyll naturally from foods?
Chlorophyll is in all leafy plants. Levels are especially high in some vegetables we eat, like spinach, parsley, and green beans.
What are the risks?
- Side effects. There could be minor effects on the stomach/intestines, like nausea/vomiting from chlorophyll supplements.They seem to be fairly safe, though.
- Risks. Chlorophyll may make some people more likely to get a rash from the sun. We don't know if chlorophyll is safe for children or for women who are pregnant or breastfeeding.
- Interactions. If you take any medicines regularly, talk to your doctor before you start using chlorophyll supplements. Be careful with medications that also list sun sensitivity as a side effect, like drugs for acne, infections, and pain.
The U.S. Food and Drug Administration (FDA) does regulate dietary supplements; however, it treats them like foods rather than medications. Unlike drug manufacturers, the makers of supplements don’t have to show their products are safe or effective before selling them on the market.
