Does Liquid Chlorophyll Work? Evidence-Based Guide

Chlorophyll is the green pigment that allows plants to convert sunlight into energy through photosynthesis. It has also been part of the human diet throughout history as a natural component of green vegetables like spinach, kale, and lettuce. But when people ask "does Liquid Chlorophyll work," they're usually asking about the supplement form — and it's important to understand exactly what that is.

Most Liquid Chlorophyll supplements, including Nature's Sunshine Liquid Chlorophyll, contain sodium copper chlorophyllin (SCC), a semisynthetic, water-soluble derivative of natural Chlorophyll. In this form, the central magnesium atom found in plant Chlorophyll is replaced with copper, and the fat-soluble phytol tail is removed. This makes the compound dissolve cleanly in water — something natural Chlorophyll cannot do.

This formula is designed to support natural blood-cleansing processes, encourage proper immune response, strengthen the body on a cellular and molecular level, and act as a natural deodorizer. Chlorophyllin has been used in traditional and clinical settings for more than 50 years, and while some areas of research are more robust than others, there is a meaningful body of evidence worth exploring.

When evaluating whether Liquid Chlorophyll works, it helps to look at the evidence area by area rather than making sweeping claims. Here's what the research actually shows:

Carcinogen Binding and Environmental Toxin Support

This is the best-studied area of chlorophyllin's use in humans. Research suggests that chlorophyllin may form tight molecular complexes with certain chemicals known or suspected to cause cancer — including aflatoxin B1, polyaromatic hydrocarbons from tobacco smoke, and heterocyclic amines from cooked meat. A landmark randomized, double-blind, placebo-controlled trial in 180 adults in Qidong, China found that 100 mg chlorophyllin three times daily for four months produced a 55% reduction in urinary aflatoxin-DNA adduct biomarkers compared to placebo. A subsequent crossover pharmacokinetic study confirmed that both chlorophyllin and Chlorophyll may reduce aflatoxin bioavailability.

Traditional Blood-Cleansing and Detoxification Support

Chlorophyll has been used as a traditional internal cleanser and detoxifier for decades. Its structural similarity to hemoglobin — both are tetrapyrrole ring structures — has historically led practitioners to associate Chlorophyll-rich preparations with blood health. Sodium iron chlorophyllin (a different form than the copper chlorophyllin in this product) has been studied in clinical trials for iron-deficiency anemia, but standard plant-based Chlorophyll containing magnesium (or copper, as in SCC) lacks robust human clinical evidence for directly raising hemoglobin or red blood cell counts.

Deodorizing Effects

Chlorophyll has been marketed as an "internal deodorant" since the 1950s. A 1980 study found that chlorophyllin administration was helpful in controlling body and fecal odors in 62 geriatric nursing home patients. Another study in patients with trimethylaminuria found that oral SCC significantly decreased urinary trimethylamine. However, there is little modern evidence for this benefit in otherwise healthy individuals.

Immune Support

Chlorophyllin has been traditionally attributed immune-supporting properties, and preclinical evidence suggests potential immunostimulatory effects, including enhancement of white blood cell production and anti-inflammatory modulation. However, direct human clinical evidence for specific immune outcomes such as infection resistance or immune cell counts is currently absent.

An Honest Note on Bioavailability

Little is known about the bioavailability and metabolism of Chlorophyll in humans. Animal studies suggest only about 1–3% of Chlorophyll is absorbed, while human estimates suggest approximately 5% bioavailability. The pharmacokinetic profiles of many Chlorophyll derivatives remain poorly characterized, which complicates dose optimization. This is an area that needs further investigation.

Liquid Chlorophyll may appeal to anyone looking for a traditional internal cleanser and daily green supplement to add to their water. Based on its formulation and the available evidence, it may be especially relevant for:

• Those interested in whole-body cleansing support: Chlorophyll has been traditionally used as an internal detoxifier, and the aflatoxin chemoprevention data provide a scientific basis for specific toxin-binding activity in the gastrointestinal tract.
• People seeking blood health support: Chlorophyll's structural relationship to hemoglobin has historically led to its use in traditional blood-supporting preparations, though this application is rooted more in traditional practice than in controlled clinical evidence for standard plant-based Chlorophyll.
• Those wanting immune system encouragement: While direct human clinical evidence is still developing, chlorophyllin has been traditionally positioned as an immune tonic, with preclinical research suggesting potential immunostimulatory and anti-inflammatory effects.
• Anyone looking for a natural internal deodorizer: Chlorophyllin has been used orally as an internal deodorant for more than 50 years, with some older clinical evidence supporting its use in specific populations.

If you're unsure whether Liquid Chlorophyll is a good fit for your wellness goals, our naturopath offers free consultations to help you sort through the options.

Take 2 tablespoons (30mL) in an 8 fl oz glass of cold water daily. Refrigerate after opening.

Each 30 mL serving provides 90 mg of sodium copper chlorophyllin. The liquid format makes it easy to mix into your daily water — many people enjoy the mild, slightly minty taste. The 32 oz bottle provides a generous supply for daily use.

Natural chlorophylls are not known to be toxic, and no toxic effects have been attributed to chlorophyllin despite more than 50 years of clinical use in humans. When taken orally, chlorophyllin may cause green discoloration of urine or feces, or yellow or black discoloration of the tongue — these are harmless cosmetic effects. There have been occasional reports of mild diarrhea. Since the safety of Chlorophyll supplements has not been tested in pregnant or lactating women, they should be avoided during pregnancy and lactation. Individuals with Wilson's disease or other rare disorders of copper metabolism should consult a healthcare provider before use due to the copper content.
