Swanson Liquid Chlorophyll 100 mg β Full Guide
Explore our deep-dive guide on swanson Liquid Chlorophyll 100 mg: what it is, key ingredients, how to take it, and who benefits from this whole-body cleanser.
What Is Liquid Chlorophyll and Why Does It Matter?
Chlorophyll is the green pigment that drives photosynthesis in plants β but its benefits extend well beyond the botanical world. Swanson Liquid Chlorophyll 100 mg delivers a convenient, water-soluble form of this pigment designed to support natural blood-cleansing processes, encourage a healthy immune response, and act as a natural deodorizer.
Nature's Sunshine harnesses Chlorophyll's power in this Liquid Chlorophyll formula. Chlorophyll nourishes plant life by converting the sun's rays into energy through photosynthesis, but it also nourishes human life by supporting natural blood cleansing. It may also encourage healthy immune system response and acts as a natural deodorizer.
This 32-oz liquid format makes it easy to mix into a daily glass of water, giving you a straightforward way to incorporate Chlorophyll into your routine. The formula is built around sodium copper chlorophyllin, a semisynthetic, water-soluble derivative of natural Chlorophyll that has been used in traditional and clinical settings for more than 50 years.
How Liquid Chlorophyll Supports Your Body
The active ingredient in this formula β sodium copper chlorophyllin β works through several mechanisms that have been explored in both traditional practice and scientific research.
Blood-Cleansing and Detoxification Support
Chlorophyll and its derivatives have been traditionally used as internal cleansers and detoxifiers for decades. Research suggests that chlorophyllin can form tight molecular complexes with certain chemicals known or suspected to cause harm β including polyaromatic hydrocarbons found in tobacco smoke and aflatoxin B1 β potentially interfering with their gastrointestinal absorption. A landmark randomized, double-blind, placebo-controlled trial in 180 adults found that chlorophyllin supplementation produced a 55% reduction in urinary aflatoxin-DNA adduct biomarkers versus placebo.
Immune Response
Chlorophyllin has been traditionally attributed immune-supporting properties. Preclinical evidence points to immunostimulatory effects, potential enhancement of white blood cell production, and anti-inflammatory modulation. Traditional and naturopathic frameworks have historically positioned Chlorophyll as an immune tonic.
Natural Deodorizer
Chlorophyll has been marketed as an internal deodorant since the 1950s. A study published in 1980 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 sodium copper chlorophyllin significantly decreased urinary trimethylamine.
Cellular and Molecular Strength
Chlorophylls present significant antioxidant activity through chelation of reactive ions and scavenging of free radicals. The chemical nature of the porphyrin ring allows chlorophylls to function as hydrogen donors, helping to prevent oxidative DNA damage and lipid peroxidation.

Who Is Liquid Chlorophyll For?
This swanson Liquid Chlorophyll 100 mg formula may appeal to a wide range of adults looking for daily whole-body support:
- Those seeking internal cleansing support: Chlorophyllin has been traditionally used as an internal cleanser and detoxifier, with scientific backing for its ability to bind certain environmental toxins in the gastrointestinal tract.
- People interested in blood health: Chlorophyll's structural similarity to hemoglobin has made it a longstanding choice in traditional wellness practices for supporting healthy blood.
- Anyone wanting immune system support: Chlorophyllin has historically been positioned as an immune tonic in traditional and naturopathic frameworks.
- Individuals concerned about body odor: Chlorophyllin has been used as a natural internal deodorizer since the 1950s, with older studies documenting its helpfulness in specific populations.
If you're unsure whether Liquid Chlorophyll fits your wellness goals, our naturopath offers free consultations to help you find the right path.
Important note: 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-containing supplements including sodium copper chlorophyllin.
How to Take Liquid Chlorophyll
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 mixes easily into cold water, making it simple to incorporate into your morning or afternoon routine.
When taken orally, supplemental chlorophyllin may cause green discoloration of urine or feces, or yellow or black discoloration of the tongue β these are normal and harmless side effects. There have also been occasional reports of mild digestive changes. Oral chlorophyllin may result in false positive results on guaiac card tests for occult blood, so let your healthcare provider know if you're taking this supplement before any such testing.

Frequently asked questions
Is swanson Liquid Chlorophyll 100 mg the same as natural Chlorophyll from plants?
Not exactly. This product contains sodium copper chlorophyllin, a semisynthetic, water-soluble derivative of Chlorophyll. In natural Chlorophyll, a magnesium atom sits at the center of the molecule and a fat-soluble phytol tail makes it insoluble in water. In chlorophyllin, the magnesium is replaced by copper and the phytol tail is removed, making it water-soluble and suitable for liquid supplement formulas. Most commercial 'Chlorophyll water' and liquid supplement products use chlorophyllin rather than natural Chlorophyll for this reason.
Why might my urine or stool turn green after taking Liquid Chlorophyll?
Green discoloration of urine or feces is a normal and well-documented side effect of taking supplemental chlorophyllin orally. You may also notice yellow or black discoloration of the tongue. These color changes are harmless. However, be aware that oral chlorophyllin may cause false positive results on guaiac card tests for occult blood, so inform your healthcare provider if you're undergoing such testing.
Can I take Liquid Chlorophyll during pregnancy or breastfeeding?
The safety of Chlorophyll or chlorophyllin supplements has not been tested in pregnant or lactating women, so they should be avoided during pregnancy and lactation. If you have questions about supplementation during this time, our naturopath is available for a free consultation.
Does Liquid Chlorophyll really help with body odor?
Chlorophyllin has been used as an internal deodorant since the 1950s. A study published in 1980 found it was helpful in controlling body and fecal odors in 62 geriatric nursing home patients, and another small study found oral chlorophyllin significantly decreased urinary trimethylamine in patients with trimethylaminuria (a metabolic disorder causing body odor). However, there is little modern evidence for this benefit in otherwise healthy people. The existing evidence is stronger for specific populations such as colostomy patients and those with trimethylaminuria.
Are there any drug interactions I should know about?
A case of delayed methotrexate clearance was reported following administration of a supplement containing Chlorophyll, suggesting a potential interaction with at least one chemotherapy agent. Additionally, chlorophyllin forms tight molecular complexes with certain chemicals, and carefully controlled studies have not yet determined whether a similar mechanism might limit uptake of required nutrients or co-administered medications. If you take prescription medications, speak with your healthcare provider before adding Liquid Chlorophyll to your routine.
How does chlorophyllin support blood health?
Chlorophyll's structural similarity to hemoglobin β both are tetrapyrrole ring structures β has traditionally led to the belief that Chlorophyll-rich preparations support blood health and red blood cell production. Research on a related compound, sodium iron chlorophyllin, has shown clinical evidence supporting hemoglobin levels in specific populations, including a Phase IV multicenter trial and a meta-analysis of 39 trials. However, standard plant Chlorophyll (containing magnesium rather than iron, or copper as in this supplement) lacks the same level of robust human clinical evidence for directly raising hemoglobin.
