What Chlorophyllin is, and what it does.
- Does it work
- Niche but real. If you're dealing with odor issues (medical or otherwise), it genuinely works. For general 'detox' claims, save your money.
- How much to take
- 100-300 mg daily. Start at 100 mg and increase if needed.
- The first dose
- You might notice greener stool within the first day. Odor reduction takes a few days.
- With regular use
- Consistent daily use keeps odor under control. No tolerance buildup.
- How well tolerated
- Well tolerated. FDA-approved for internal deodorant use. Can cause green discoloration of urine and stool (harmless).
- How it feels
- You don't feel it working. What you notice is the absence of something: less odor.
About 200mg a day is the studied dose.
How much to take a dayMedium confidence
Up to 100mgA supporting amount. Helps a little, not the studied dose.
100mg to 200mgEnough for most people, and where a lot of good products land.
200mg
The doseThe daily amount the trials actually used. A product at this figure is dosed right where the research is.

Questions people ask about Chlorophyllin.
- Why is my poop green?
- That's the chlorophyllin. Totally normal and harmless. It means the supplement is reaching your gut.
- Will this actually help with body odor?
- For fecal and internal odor, yes. For armpit BO from sweat, not really. Different mechanisms.
- Is chlorophyllin water worth it?
- The liquid drops work fine. The trendy 'chlorophyll water' products are often underdosed. Check the actual mg per serving.
- Does it really detox your body?
- It binds certain compounds in your gut. But the broad 'detox' marketing is overhyped. Your liver handles detox.
- Is this the same as eating greens?
- Similar source, different form. Chlorophyllin is modified to be water-soluble and more concentrated.
- Can I take it with medications?
- Space it 2 hours apart from meds. Its binding action could theoretically reduce drug absorption.
Nothing to show here, and the reason why.
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Chlorophyllin has none that clears that bar.
No pairing for Chlorophyllin has cleared review yet.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.

Plays well withEstablished knowledge, not a trial
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Chlorophyllin + Ascorbic acidCo-administered in an animal oxidative-stress model
Sodium copper chlorophyllin and ascorbic acid were given alone and together in a rodent study of barium chloride exposure, and the combination arm was included specifically to test whether the two act on the same oxidative-stress markers. These were tissue markers in animals, not human outcomes. Both compounds are water soluble and are stable together in solution, which is why the pairing shows up in beverage and greens formulas.
Chlorophyllin + ZincDefined coordination chemistry of the sodium zinc chlorophyllin salt
Chlorophyllin holds a divalent metal in the centre of its chlorin ring, and sodium zinc chlorophyllin is the version where that position is filled by zinc rather than copper. The zinc is part of the molecule, so a formula using this salt is contributing zinc whether or not it says so. One published non-human experiment paired sodium zinc chlorophyllin with calcium and L-proline to look at intestinal calcium transport.
Chlorophyllin + IronIn vitro digestion and Caco-2 uptake work on iron chlorophyllin
Iron can occupy the central metal site, and iron chlorophyllin has been examined in a digestion model coupled to Caco-2 monolayers for how much iron becomes available for cell uptake. That is a cell-culture measurement of bioaccessibility, not a human iron-status outcome. The relevance to a formulator is that the metal in the ring is a design choice with its own absorption behaviour.
Chlorophyllin + L-ProlineCombination arm of the same non-human transport experiment
L-proline was one of three components in the tested combination with calcium and sodium zinc chlorophyllin. The report describes the trio together, so the contribution of any single part is not separable from the design. Non-human model, mechanism-level endpoint.
Chlorophyllin + Activated charcoalEstablished behaviour of non-selective adsorbents
Activated charcoal adsorbs a wide range of organic molecules without selecting among them, and a large planar pigment like chlorophyllin is exactly the sort of molecule it holds. Taken in the same dose window, charcoal can reduce how much chlorophyllin stays free in the gut lumen. Separating the two by a few hours is the ordinary formulation answer.
Chlorophyllin + ProbioticsAnimal work on chlorophyllin and faecal bacterial counts
A swine feeding study measured faecal Escherichia coli counts with and without chlorophyllin in medicated and unmedicated diets, which puts chlorophyllin in contact with the gut bacterial community. Whether it helps or hinders a specific supplemented strain in a person has not been measured. The direction of the interaction is unsettled, so a formula pairing the two is making a bet rather than following data.
Chlorophyllin + GlutathioneOverlapping redox handling in animal models
Rodent studies of chlorophyllin report changes in tissue glutathione and related redox markers rather than in clinical endpoints. Supplemental glutathione acts on the same marker set, so the two overlap in what they move. No human study has measured them together.
Chlorophyllin + Vitamin EShared antioxidant chemistry across aqueous and lipid phases
Chlorophyllin is water soluble and tocopherols sit in the lipid phase, so the two cover different compartments of the same oxidative chemistry. Animal reports on chlorophyllin track lipid peroxidation products, which is the marker tocopherols also affect. This is a mechanistic pairing, not a tested one.
Chlorophyllin + QuercetinBoth are planar polyphenolic metal binders
Quercetin binds divalent metals and so does the chlorin ring system, which means the two can compete for the same free copper, zinc or iron in a mixed formula. That competition changes what each one is carrying, not whether either is present. Worth checking in a stability run rather than assuming it is inert.
Who should be cautious
Talk to a doctor before taking Chlorophyllin if any of these apply to you: Can cause green discoloration of urine/stool (harmless), Limited evidence for most 'detox' claims, May cause GI discomfort. These are flags to check first, not effects Chlorophyllin is known to cause.

The forms it comes in.
Chlorophyllin copper complex sodiumCopper occupies the central position of the chlorin ring; the carboxylate groups are sodium salts, giving a freely water-soluble green powder.Fits Aqueous drinks, drops, chewables and any format where a clear green solution is wanted.Trade-off Every serving carries copper as part of the molecule, so the copper has to be counted in the formula total.Active and formulation aid
Chlorophyllin zinc complex sodiumSame chlorin backbone with zinc in the central metal site instead of copper; also water soluble.Fits Formulas that already carry copper elsewhere, or that want the metal contribution to be zinc.Trade-off Less studied than the copper version, and the zinc it contributes must be counted the same way.Active and formulation aid
Iron chlorophyllinIron sits in the central position of the ring; behaviour through digestion has been examined in cell-uptake models.Fits Research and development work on pigment-bound mineral delivery.Trade-off Human data are absent; the available work is in vitro, and iron in a pigment complex behaves differently from a simple iron salt.
Chlorophyll a and bThe unmodified plant pigment, with magnesium in the ring and the phytol tail intact, which makes it fat soluble and much less stable to heat and acid.Fits Oil-based and whole-food green formats where the intact pigment is the point.Trade-off Poor water solubility and easy loss of the magnesium during processing; it is a different molecule from chlorophyllin, not a synonym.
E141(ii), copper complexes of chlorophyllinsThe same sodium copper chlorophyllin specified and assayed for use as a colour rather than for an intake amount.Fits Tinting capsules, gummies and drink powders green without a synthetic dye.Trade-off Specified for colour strength, so the active amount per serving is usually small and not the reason it is on the label.Formulation aid
