Chlorophyllin Drug Interactions, Uses, Effectiveness, Safety & More
What is this page for?
First and foremost: how Chlorophyllin interacts with medications. The heart of this page is the interaction list — every drug Chlorophyllin is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Chlorophyllin is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist.

Add one medicationChlorophyllin Drug Interactions: The Bottom Line
From the HelloPharmacist Editorial Team · Updated July 2026Based on the available evidence, Chlorophyllin drug interactions center on one main concern: a moderate risk of extra sun sensitivity when it is taken with medicines that already make the skin more sensitive to light. None of the listed interactions are rated major, and every one of them involves this same photosensitivity effect.
The medicines that deserve the most attention are photosensitizing drugs, a broad group that makes the skin react more strongly to sunlight. This concern is reasonably well documented: chlorophyll, the compound chlorophyllin is made from, has been reported to cause photosensitization, and taking it by mouth has been linked in multiple case reports to pseudoporphyria, a blistering skin reaction triggered by light. Combining chlorophyllin with these medicines may add to that effect, so an unusual sunburn-like reaction is the sign to watch for.
The number of interacting medications looks large, but it does not reflect hundreds of separate problems. Nearly all of these drugs appear because they share one trait, sensitizing the skin to light, so the whole list points back to a single additive effect rather than many different risks.

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
- Each drug listed above links to the full report for that exact Chlorophyllin combination — clinical detail, likelihood, evidence level, and citations.

Photosensitizing Drugs
Theoretically, concomitant use of chlorophyllin with photosensitizing drugs may have additive effects.
Chlorophyllin is a semi-synthetic derivative of chlorophyll. Chlorophyll has been reported to cause photosensitization. Orally, chlorophyll has also been associated with the development of pseudoporphyria in multiple case reports.
Chlorophyllin: Uses, Safety & Side Effects
Chlorophyllin is a water-soluble, semi-synthetic form of chlorophyll most often used to help control body and fecal odor and to support wound healing. The best evidence is for its use as a deodorizing agent, while many popular claims like detoxification and digestive benefits are not well proven. It is generally considered safe for short-term use, but talk to your pharmacist or doctor before starting it, especially during pregnancy or breastfeeding.

- Part used
- Semi-synthetic derivative of chlorophyll (originally from green plant leaves)
- Common forms
- Tablets, capsules, liquid drops, topical ointments and sprays
- Body and breath odor control
- Wound and skin care
- Internal deodorant for ostomy or incontinence
- Detoxification claims
- Digestive support
Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.

Overview
Chlorophyllin is a man-made (semi-synthetic) version of chlorophyll, the green pigment that plants use to capture sunlight. To make chlorophyllin, chlorophyll taken from green plant leaves is chemically changed in a laboratory. Most products contain a form called sodium copper chlorophyllin, in which the magnesium in natural chlorophyll is replaced with copper.
This change makes chlorophyllin more stable and more water-soluble than natural chlorophyll, which makes it easier to use in supplements and as a green food coloring. People take it by mouth in tablets, capsules, or liquid drops, and it is also found in some topical ointments and sprays.
It is widely marketed for purposes such as reducing body and breath odor, helping with wound care, and supporting "detox" and digestion. Some of these uses have more scientific support than others.
How it works
Chlorophyllin's exact actions in the body are not fully understood. As a deodorizer, it is thought to bind to or neutralize certain odor-causing compounds, though the details are not firmly established.
In laboratory and animal studies, chlorophyllin acts as an antioxidant and can bind to certain cancer-causing chemicals, which may make it harder for the body to absorb them. Researchers have also looked at possible anti-inflammatory effects.
It is important to remember that much of this work comes from test-tube and animal research. What happens in a lab does not always translate into proven benefits for people.

How to read these evidence grades
Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.
Possibly Ineffective Urinary odor
Oral chlorophyllin does not seem to reduce urinary odor. <b>Details</b>: One small clinical study in older adults with an indwelling catheter due to urinary incontinence shows that taking chlorophyllin 100 mg daily for two weeks does not reduce urinary odor when compared with placebo.
Also studied for 9 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Acne
It is unclear if topical chlorophyllin is beneficial in patients with acne.
Insufficient Reliable Evidence To Rate Body odor
Although there is interest in using oral chlorophyllin for body odor, there is insufficient reliable information about the clinical effects of chlorophyllin for this purpose.
Insufficient Reliable Evidence To Rate Cancer
Although there is interest in using oral chlorophyllin for cancer, there is insufficient reliable information about the clinical effects of chlorophyllin for this condition.
Insufficient Reliable Evidence To Rate Constipation
Although there is interest in using oral chlorophyllin for constipation, there is insufficient reliable information about the clinical effects of chlorophyllin for this purpose.
Insufficient Reliable Evidence To Rate Fecal odor
Although there is interest in using oral chlorophyllin for fecal odor, there is insufficient reliable information about the clinical effects of chlorophyllin for this purpose.
Insufficient Reliable Evidence To Rate Flatulence
Although there is interest in using oral chlorophyllin for flatulence, there is insufficient reliable information about the clinical effects of chlorophyllin for this purpose.
Insufficient Reliable Evidence To Rate Leukopenia
It is unclear if oral chlorophyllin reduces the severity of leukopenia.
Insufficient Reliable Evidence To Rate Wound healing
Although there is interest in using topical chlorophyllin for wound healing, there is insufficient reliable information about the clinical effects of chlorophyllin for this purpose.
Insufficient Reliable Evidence To Rate Wrinkled skin
It is unclear if topical chlorophyllin reduces fine lines and wrinkles.

Safety & precautions
Chlorophyllin is generally considered well tolerated when taken by mouth for short periods or applied to the skin. Still, high-quality long-term safety data are limited.
People who are sensitive to copper or who have conditions affecting copper handling should be cautious, since the common form contains copper. If you have a chronic health condition or take other medicines, check with your pharmacist or doctor first.
For pregnancy and breastfeeding, there is not enough reliable safety information. Because of this uncertainty, it is best to avoid chlorophyllin during these times unless your healthcare provider specifically advises otherwise.
Always buy from a reputable brand, since supplements are not tightly regulated and product quality can vary.
Side effects
Side effects are usually mild. The most commonly reported ones include:
- Green discoloration of the stool, urine, or tongue (this is harmless)
- Mild stomach upset, diarrhea, or cramping
- Skin irritation when topical products are used
Serious reactions are uncommon. As with any supplement, stop using it and seek medical care if you have signs of an allergic reaction, such as rash, itching, swelling, or trouble breathing.
Chlorophyllin: Reported Adverse Effects
Documented safety reports on Chlorophyllin from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.
Reports by conditionDermatitis Dermatologic
Since chlorophyllin is a semi-synthetic derivative of chlorophyll, there is some concern that it could cause similar adverse effects. Topically, chlorophyll cream has been reported to cause dermatitis. Orally, chlorophyll can cause photosensitization. In case reports, oral consumption of chlorophyll has been associated with the development of pseudoporphyria. Two females developed easily traumatized blisters on their hands after consumption of a Swisse Chlorophyll drink. In one case series, four males developed skin blisters and skin erosions after taking oral chlorophyll 100-1200 mg daily for 6.5 months up to 7 years. Resolution of symptoms was delayed for 2-8 months after chlorophyll discontinuation. To date, chlorophyllin has not been reported to cause similar adverse effects; however, in vitro toxicology research suggests that chlorophyllin is phototoxic.

Dosing
There is no official standardized dose for chlorophyllin, and the amount used in studies has varied. Products come in different strengths and forms, so the right amount depends on the specific product and how it is being used.
The safest approach is to follow the directions on the product label and not exceed the recommended amount. Because needs differ from person to person, ask your pharmacist or doctor for guidance before starting, especially if you have a health condition or take other medicines.
