Chlorophyll / Chlorophyllin
A semi-synthetic copper-containing derivative of plant chlorophyll. Massively popular on social media for skin and 'detox'. The one thing it has good evidence for is not on the label.
Chlorophyll / Chlorophyllin quick facts
| Suggested dose | 100–300 mg daily of chlorophyllin. |
| How often | Daily |
| Who it's for | Very little reason for most people. |
The standout evidence is a randomized trial in China showing reduced aflatoxin-DNA adducts, which is one of very few human carcinogen-biomarker results anywhere in this catalog. The internal-deodorant use has older but real evidence. Chlorophyllin is the semi-synthetic water-soluble form and is what was studied; natural chlorophyll behaves differently.
How Chlorophyll / Chlorophyllin actually works
Sodium copper chlorophyllin forms tight molecular complexes with planar aromatic carcinogens — aflatoxin and polycyclic aromatic hydrocarbons — through direct stacking interaction, blocking their absorption. This is a physical binding mechanism with a defined structural basis rather than a vague detoxification claim.

Graded by what exists behind each claim.
✅ Clinically validated
- A randomized trial in China found chlorophyllin reduced aflatoxin-DNA adducts by 55% in a high-exposure population — a real, striking result with no relevance to most people's diets.
- Used clinically as an internal deodorant for colostomy and incontinence odor, with older supporting studies.
- No credible trial supports the acne, weight loss, blood-building or general detoxification claims that sell it.
📊 Correlative data
- The 'it's structurally like hemoglobin so it builds blood' claim is chemically superficial and physiologically wrong — the metal center is magnesium in chlorophyll and copper in chlorophyllin, not iron.
🧪 Theoretical / extrapolated benefits
- Forms molecular complexes with planar aromatic carcinogens in the gut, blocking their absorption. That is the aflatoxin mechanism and it is genuinely interesting.

What Chlorophyll / Chlorophyllin actually does
Chlorophyllin is not chlorophyll, and the differences are three deliberate chemical steps. Plant chlorophyll is a magnesium chlorin carrying a long phytol tail, which makes it lipophilic and unstable. Making chlorophyllin means saponifying off the phytol tail and the methyl ester, exchanging the central magnesium for copper, and taking the result as sodium salts. What you get is water-soluble, shelf-stable, and semi-synthetic Hayes 2020. Every human trial used that material, not the green pigment in spinach.
It is also not one molecule. Commercial sodium copper chlorophyllin is a mixture, dominated by copper chlorin e4 and copper chlorin e6 in proportions that vary with manufacture Ferruzzi 2002 Hayes 2020. “100 mg of chlorophyllin” is a mass of a mixture, which is why no two products are necessarily the same product.
The mechanism is molecular stacking, and it is exquisitely specific about shape. The chlorin ring is a large flat aromatic surface. It forms non-covalent, face-to-face complexes with other large flat aromatic molecules — aflatoxin B1, heterocyclic amines from charred meat, polycyclic aromatic hydrocarbons — and the complex is too big and too polar to cross the intestinal wall, so the carcinogen leaves in the stool instead of entering the portal blood Egner 2003. This is an interceptor, and it works on planar polycyclic organics.
Which is exactly why it cannot do what the marketing says. Lead, mercury, cadmium and arsenic in the gut are ions and oxyanions. They have no aromatic surface to stack against, so the one mechanism this molecule has is unavailable to them. The bentonite page argued that a binder's problem is selectivity and access; chlorophyllin's problem is prior to both — the chemistry it uses does not apply to the analyte it is sold against. That is a stronger objection than “no evidence”, and it is checkable from first principles.
There is a second, systemic mechanism and it is not purely luminal. Copper chlorin e4 is taken up by human intestinal cells in culture Ferruzzi 2002, and absorbed chlorophyll derivatives are credited with induction of phase II detoxifying enzymes and interference with cytochrome-mediated bioactivation of procarcinogens Hayes 2020. So “it stays in the gut” is not true here, which matters for both the mechanism and the safety section.
And the blood-building claim is chemically empty. Chlorophyll's central metal is magnesium, chlorophyllin's is copper, and hemoglobin's is iron. The porphyrin resemblance is real and irrelevant: heme synthesis is not limited by the availability of ring-shaped molecules.
Cell, rodent, human — and where it stops
In the dish. Complex formation with planar carcinogens, and digestive stability plus uptake of copper chlorin e4 by Caco-2 human intestinal cells Ferruzzi 2002.
In animals. The chemoprevention chain was built in rodent and trout aflatoxin models before it went anywhere near a person Egner 2003, and the parallel dioxin work showed the same family of pigment both blocking absorption and accelerating excretion in rats Morita 2001.
In humans, and this is a genuinely good trial. One hundred and eighty healthy adults in Qidong, China — a population with heavy dietary aflatoxin exposure and a high liver cancer rate — were randomized to 100 mg of chlorophyllin or placebo three times a day for four months. Median urinary aflatoxin-N7-guanine, the DNA adduct biomarker, fell 55% against placebo, P = 0.036 Egner 2001. A randomized, placebo-controlled, biomarker-based prevention trial is a higher standard of evidence than almost anything else on this shelf.
And the pharmacokinetic study that followed is unusually elegant. Four human volunteers were given an ethically-approved ultra-low dose of radiolabelled aflatoxin B1 — 30 nanograms, 5 nanocuries — with and without chlorophyll or chlorophyllin, with each protocol repeated three times per volunteer and detection by accelerator mass spectrometry Jubert 2009. That is a direct human absorption measurement rather than an inference from a urinary metabolite.
The obstacle is the exposure, not the drug. Everything in that chain is about intercepting a specific dietary carcinogen in people who are eating a lot of it. A reader in a country with a regulated food supply has an aflatoxin exposure orders of magnitude lower, and there is no biomarker in them for a binder to lower. The same limitation applies to the clay studied in the same kind of population, which reduced a urinary aflatoxin biomarker by up to 58% Wang 2008 — two completely different materials, one target, one setting, and neither result travels to a Western kitchen.
The second obstacle is that the popular claims have no oral trial at all. The acne evidence is a three-week open-label pilot of a topical copper chlorophyllin complex in 10 subjects Stephens 2015. Ten people, three weeks, no control arm, applied to the skin. That is the entire basis of a claim sold as a drink. The older clinical use with any supporting literature is internal deodorization in geriatric and incontinent patients Young 1980, which nobody markets and which at least has a defined observable.
Chlorophyll / Chlorophyllin — which form, and does it matter
Read the ingredient line, because three different things are sold as the same thing. Sodium copper chlorophyllin is the semi-synthetic, water-soluble material with all the human evidence Egner 2001 Jubert 2009. “Liquid chlorophyll” is usually the same chlorophyllin diluted. True chlorophyll, extracted from alfalfa or spinach, is a magnesium complex that is lipophilic and degrades in acid, and it was the comparator rather than the winner in the human absorption study Jubert 2009.
The dose that produced the human result is 300 mg a day, split into three. One hundred milligrams three times daily for four months Egner 2001. This site's card says 100 to 300 mg daily, so the bottom of its range is a third of the trial dose and taken as a single dose rather than split. For an interceptor that has to be present when the meal is, splitting is not a convenience.
Timing is the mechanism. A complexing agent can only complex what is in the lumen at the same time as it is Egner 2003. Taken with food it can intercept; taken on an empty stomach an hour before, it cannot. Every trial dosed it with meals, and that is a formulation instruction rather than a habit.
Nothing on a label describes the actual mixture. The proportions of copper chlorin e4 and e6 differ between manufacturers and lots Ferruzzi 2002 Hayes 2020, and no product declares them. Where a molecule's mechanism is its planar surface, the identity of the chlorin is not a manufacturing detail.
Copper is a dose, not a decoration. This is a copper complex taken at hundreds of milligrams a day for months Egner 2001, and part of it is absorbed rather than passing through Ferruzzi 2002. Anyone already taking a copper-containing multivitamin is stacking, and nobody has published a copper balance study on chronic chlorophyllin use.
What would have to be true, and how you would know it was not
1. Green is the delivery marker and it is immediate. Predict green stool within a day of starting, and often a green tongue. That is not a side effect to be tolerated, it is evidence the pigment is present in the lumen where the mechanism is supposed to happen. No color change means no delivery.
2. The prediction that cuts against the entire detox positioning. Predict a heavy metals panel — blood lead, blood or urine mercury, urine cadmium, urine arsenic — is unchanged after 12 weeks. The mechanism is aromatic stacking with planar polycyclic molecules Egner 2003; metal ions have no such surface. This is a prediction from chemistry rather than from an absence of trials, which makes it stronger.
3. The acne prediction, with a real counting method. Predict no change in inflammatory lesion count over 12 weeks of oral chlorophyllin, because the only acne data is topical, open-label, 10 subjects, three weeks Stephens 2015. Count lesions on the same half of the face in the same light at baseline, 6 weeks and 12 weeks; photographs from a phone are enough. Predict also that anyone who does improve improved on the season, the sleep or the topical they started in the same week.
4. Where an effect should actually be visible. If deodorizing is what you want, the endpoint is a rated odor score by someone other than you, over two to four weeks, which is broadly the way the old clinical literature assessed it Young 1980. And if you eat heavily charred meat, the mechanistically coherent test is a dose taken with that meal — a heterocyclic amine is planar and polycyclic, which is precisely the shape this molecule intercepts Egner 2003. Nobody has run that trial, and it is the one this product deserves.
What nobody has tested yet
Nobody has tested it against a Western exposure. The adduct result belongs to a population with heavy aflatoxin intake Egner 2001. The parallel experiment in people eating a high-temperature-cooked Western diet, with urinary heterocyclic amine metabolites as the endpoint, has never been run — and it is the study that would tell an ordinary reader whether this molecule has any job in their kitchen.
Nobody has taken it to an outcome. Aflatoxin-DNA adducts are a biomarker of exposure, not a case of liver cancer Egner 2001 Egner 2003. No trial has been long enough or large enough to show that lowering the biomarker lowers the disease, and honest chemoprevention writing says that out loud.
Nobody has characterized what is in the bottles. A survey of marketed chlorophyllin products for copper chlorin e4 and e6 content and for total copper, benchmarked against the material used in the randomized trial Egner 2001 Ferruzzi 2002, would take one chromatography run per product and has not been published.
And nobody has measured copper balance on chronic use. Hundreds of milligrams a day of an absorbed copper complex Ferruzzi 2002 taken for months by people who are also taking multivitamins is an unstudied copper exposure. Serum copper, ceruloplasmin and a liver panel over six months would answer it, and nobody has looked.
Chlorophyll / Chlorophyllin — its own safety story, not its category's
The specific risk here is the copper, and it has a named contraindication. Sodium copper chlorophyllin is a copper complex and part of it is absorbed Ferruzzi 2002. In Wilson disease, where biliary copper excretion is impaired, a daily copper-bearing supplement is exactly the wrong product; the same caution applies to anyone with unexplained liver enzyme elevation and a low ceruloplasmin.
Photosensitivity is a real report and it is mechanistically expected. Chlorin rings absorb visible light and are used deliberately as photosensitizers in photodynamic therapy. A sunburn-like eruption on sun-exposed skin after starting this is the molecule doing what its chemistry says it does, and it is a particularly poor trade for a supplement bought to improve skin Stephens 2015.
The discoloration is harmless and diagnostically inconvenient. Green stool and green tongue are universal and mean nothing. They also change the appearance of stool, so tell a clinician you are taking it before any stool test or any assessment of a possible gastrointestinal bleed, where color is part of the examination.
The interaction that follows from the mechanism is with things shaped like its targets. A molecule that forms complexes with planar aromatics in the lumen Egner 2003 is not selective for carcinogens; drugs with large flat aromatic systems are plausible passengers. Nobody has studied it, which is itself the reason to separate it from medication by two hours.
And the honest framing of the risk-benefit. This is a generally benign compound whose one strong result is about a carcinogen most readers barely encounter Egner 2001, sold for skin and detoxification claims with no oral trial behind them. The harm is not toxicity; it is a person believing their metal exposure is being dealt with by a molecule that chemically cannot deal with it.

How you would know if it worked
There is no blood test for this one. That is not a criticism — it is a fact about the effect, and it changes how you should judge it.
- What to watch: If you bought it for skin — which is why almost everyone buys it — a photograph of the same area in the same light every two weeks, and a count of new spots per week. That is the honest version of an acne read, and it is worth knowing before you start that no trial supports this particular claim at all.
- How long before it means anything: Eight to twelve weeks for anything skin-related, because skin turns over on that scale. Without the photographs you will not be able to tell, since memory of your own face two months ago bends toward whatever you were hoping for.
- What will fool you: Two effects that look like signals and are not. Your stool turns green, which is harmless and feels like proof that something is happening; and some people become photosensitive, which is a poor trade in a product bought for skin. The one finding with a real trial behind it — reduced aflatoxin-DNA adducts in a high-exposure population — has nothing to do with why it is sold or with your diet.
Run it one variable at a time. Starting three things in one week means a result you cannot attribute, which is the same as no result.
Chlorophyll / Chlorophyllin — safety & side effects
- Green stool and, occasionally, green tongue — harmless and universal. GI upset and diarrhea at higher doses.
- Photosensitivity is reported. No established significant drug interactions.
- Generally benign. Not established as safe in pregnancy or breastfeeding — not because harm is documented, but because these are the two populations systematically excluded from the trials. Absence of data is not reassurance.
