NOW Foods Liquid Chlorophyll () Reviews | Guide

Chlorophyll is the green pigment found in plants that makes photosynthesis possible — converting sunlight into the energy that nourishes plant life. But Chlorophyll has also been valued for nourishing human life for decades, with documented uses dating back to the mid-twentieth century for wound healing, anti-inflammatory support, and internal deodorization.

Nature's Sunshine harnesses the powers of Chlorophyll in its Liquid Chlorophyll formula. This 32 oz liquid concentrate is designed to support natural blood-cleansing processes, encourage a healthy immune system response, strengthen the body on a cellular and molecular level, and act as a natural deodorizer.

It's worth understanding that most commercially available "Liquid Chlorophyll" products — including this one — actually contain sodium copper chlorophyllin, a semisynthetic, water-soluble derivative of Chlorophyll. Natural Chlorophyll is fat-soluble and doesn't dissolve into water cleanly, so chlorophyllin was developed specifically for liquid supplement use. In chlorophyllin, the central magnesium atom of natural Chlorophyll is replaced with copper, and the phytol tail is removed, making it water-soluble and more stable.

If you'd like personalized guidance on whether a Chlorophyll supplement fits your wellness routine, our naturopath is available for a free consultation — no appointment pressure, just honest advice.

This Liquid Chlorophyll formula is designed for adults seeking support in three interconnected areas: blood health, immune system function, and whole body cleansing.

Those interested in traditional internal cleansing and detoxification may find Chlorophyll appealing. Chlorophyll has been used as a traditional internal cleanser for decades, based on its documented ability to bind certain environmental toxins and reduce their systemic bioavailability. While the broader concept of a "whole body cleanse" via Chlorophyll is rooted in traditional use and naturopathic practice rather than controlled clinical evidence, the aflatoxin chemoprevention research does provide a scientific basis for specific toxin-binding activity.

People looking for natural deodorizing support may also benefit. Historically, Chlorophyll has been marketed as an "internal deodorant" since the 1950s, and limited studies in specific populations — such as geriatric nursing home patients and individuals with trimethylaminuria — have shown some benefit, though modern evidence in healthy individuals is largely anecdotal.

The liquid format makes it easy to mix into a daily glass of water, which appeals to those who prefer not to swallow capsules or tablets. If you're unsure whether this supplement aligns with your health goals, our naturopath offers free consultations to help you decide.

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

A few practical notes from the research literature: when taken orally, supplemental chlorophyllin may cause green discoloration of urine or feces, or yellow or black discoloration of the tongue. These are cosmetic effects, not safety concerns. There have also been occasional reports of mild diarrhea. Oral chlorophyllin may result in false positive results on guaiac card tests for occult blood — something to keep in mind if you have upcoming lab work.

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 rare disorders of copper metabolism, such as Wilson's disease, should limit exposure to copper additives including sodium copper chlorophyllin. If you take medications — particularly methotrexate or other chemotherapy agents — consult your healthcare provider, as one case report described delayed methotrexate clearance following a Chlorophyll-containing supplement.

The most robust area of human clinical research for chlorophyllin involves aflatoxin chemoprevention. A randomized, placebo-controlled trial in 180 adults found that 100 mg of chlorophyllin three times daily for four months reduced urinary aflatoxin-DNA adduct biomarkers by 55% compared to placebo. This evidence is promising but was conducted specifically in high-exposure populations in China, and no actual cancer incidence data from human trials are yet available.

For blood health, the connection between Chlorophyll and hemoglobin has long been noted due to their structural similarity — both are built around tetrapyrrole rings. Research on sodium iron chlorophyllin (a related but distinct compound) has shown significant hemoglobin increases in clinical trials. However, standard sodium copper chlorophyllin, which contains magnesium rather than iron at its core, lacks robust human clinical evidence for directly raising hemoglobin or red blood cell counts.

For immune support, chlorophyllin has been attributed immunostimulatory properties based on preclinical evidence, but direct human clinical evidence for immune-specific outcomes such as infection resistance or immune cell counts is currently absent. Traditional and naturopathic frameworks have long positioned Chlorophyll as an immune tonic.

For internal deodorization, the evidence is weak to moderate — strongest for specific populations like colostomy patients and those with trimethylaminuria, but largely anecdotal in healthy individuals.

It is worth noting that 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. However, the precise pharmacokinetics of dietary chlorophylls remain poorly understood and need further investigation.
