Chlorophyllin Extract
Also known as: Chlorophyllin, sodium copper chlorophyllin, water-soluble chlorophyll
Overview
Chlorophyllin is a semi-synthetic, water-soluble derivative of chlorophyll, the green pigment found in plants. It is produced by chemically modifying chlorophyll extracted from green plants like spinach and alfalfa, primarily by replacing magnesium with copper and removing the phytol tail, which enhances its stability and water solubility. This modification makes it more bioavailable than natural chlorophyll. Chlorophyllin is primarily used as an internal deodorant, an antioxidant, and an anti-inflammatory agent. Research also suggests its potential as a chemopreventive compound, particularly through its ability to bind and detoxify certain carcinogens like aflatoxins. It has also been investigated for its hepatoprotective effects and its role in modulating gut microbiota. While preclinical studies show promising results, human clinical evidence is still limited and heterogeneous, indicating a moderate level of research maturity.
Benefits
Chlorophyllin exhibits several evidence-based benefits, primarily stemming from its antioxidant and anti-inflammatory properties. Preclinical studies, particularly in animal models, have shown significant antioxidant and anti-inflammatory effects. For instance, a randomized controlled animal study demonstrated that oral chlorophyllin (5 mg/kg) significantly reduced liver fibrosis and inflammation induced by carbon tetrachloride in mice, leading to histological improvements and reduced mortality. This suggests a strong hepatoprotective potential. Chlorophyllin also shows promise as a chemopreventive agent by binding and inactivating toxins such as aflatoxins, which has been supported by in vitro and animal studies. This detoxification mechanism could be particularly beneficial for populations exposed to these carcinogens. Additionally, some evidence suggests chlorophyllin's ability to modulate gut microbiota and improve intestinal inflammation in animal models. While these findings are robust in preclinical settings, clinical effect sizes in humans are not yet well-established due to a lack of large-scale, high-quality randomized controlled trials. The time course for benefits in humans is also not clearly defined, though animal studies typically show effects over several weeks.
How it works
Chlorophyllin exerts its effects through multiple biological pathways. Its primary mechanism involves potent antioxidant activity, where it scavenges free radicals and reduces oxidative stress within the body. It also demonstrates anti-inflammatory effects by modulating the production and activity of various inflammatory mediators and cytokines. A key mechanism is its ability to bind and inactivate certain toxins, such as aflatoxins, in the gastrointestinal tract, thereby preventing their absorption and reducing their harmful effects. Furthermore, chlorophyllin has been shown to modulate gut microbiota composition, which can contribute to improved intestinal health and reduced inflammation. In terms of systemic interaction, it primarily offers liver protection by reducing fibrosis and necro-inflammation, and it influences the gastrointestinal tract. Being water-soluble, chlorophyllin has improved absorption and moderate bioavailability compared to natural chlorophyll.
Side effects
Chlorophyllin is generally considered safe with a low toxicity profile and is approved as a food additive (E 170). Common side effects are rare, with mild gastrointestinal discomfort being reported infrequently. There are no well-documented uncommon or rare side effects in high-quality clinical studies, and no serious adverse events have been reported in the existing literature. Regarding drug interactions, no significant interactions have been documented; however, caution is advised with anticoagulants due to a potential for mild blood-thinning effects, although this is not firmly established. Contraindications are not clearly defined due to limited research, but caution is recommended for pregnant and lactating women, as safety in these populations has not been well-established through dedicated studies. Similarly, safety in children has not been adequately studied, so its use in pediatric populations should be approached with caution.
Dosage
Optimal dosage ranges for chlorophyllin in humans are not well-established due to a lack of standardized clinical recommendations. While animal studies have used doses around 5 mg/kg body weight, human clinical trials have varied, with doses typically ranging from 100 mg to 300 mg daily in supplement form. There is no clearly defined minimum effective dose or maximum safe dose, though high doses appear to be safe in short-term use. Chlorophyllin is usually taken orally, often with meals, but no specific timing considerations have been established as critical for efficacy. The water-soluble form of chlorophyllin is preferred for better absorption compared to natural chlorophyll. Unlike some other supplements, fat intake is not necessary to enhance its absorption, and no specific cofactors have been identified as required for its activity.
FAQs
Is chlorophyllin safe for daily use?
Yes, chlorophyllin is generally considered safe for daily use, with minimal side effects reported in studies. It has a low toxicity profile.
Does chlorophyllin detoxify the body?
Chlorophyllin can bind to certain toxins, such as aflatoxins, in the digestive tract, potentially reducing their absorption and aiding in their elimination from the body.
How long before effects are seen?
There is no clear data on the time course of benefits in humans. Animal studies suggest that benefits, such as liver protection, may become apparent after several weeks of consistent use.
Can chlorophyllin cause photosensitivity?
No, there is no significant evidence in humans to suggest that chlorophyllin causes photosensitivity, unlike some other plant-derived compounds.
Is chlorophyllin the same as chlorophyll?
No, chlorophyllin is a semi-synthetic, water-soluble derivative of chlorophyll. It has a modified chemical structure that enhances its stability and bioavailability compared to natural chlorophyll.
