Understanding the Basics: Chlorophyll
Chlorophyll is the ubiquitous green pigment found in virtually all photosynthetic organisms, including plants, algae, and cyanobacteria. It plays an absolutely vital role in the process of photosynthesis, where it absorbs sunlight to convert carbon dioxide and water into energy. This makes it the foundation of most food webs on Earth.
The Structure and Role of Chlorophyll
At its core, a chlorophyll molecule consists of a porphyrin ring with a magnesium atom at its center and a long hydrocarbon tail called the phytol chain. This phytol chain makes natural chlorophyll fat-soluble, or oil-soluble, which is why it cannot simply be dissolved in water. This oil-soluble nature means that when consumed through green vegetables like spinach or broccoli, the body's absorption is generally limited.
How We Get Chlorophyll in Our Diet
The most natural way to get chlorophyll is by eating plenty of green vegetables. The chlorophyll is stored within the chloroplasts of the plant cells. While fresh foods are the best source, frozen vegetables also contain this pigment. The limited bioavailability of natural chlorophyll is why supplement companies developed a more effective alternative: chlorophyllin.
Understanding the Basics: Chlorophyllin
Chlorophyllin is a semi-synthetic, water-soluble derivative of chlorophyll that is the form most commonly found in dietary supplements marketed as 'liquid chlorophyll'. It is created through a chemical process called saponification, where the fat-soluble components and other impurities are removed from chlorophyll.
The Conversion Process to Chlorophyllin
During saponification, the long phytol tail of the chlorophyll molecule is removed, making the molecule water-soluble. Critically, the central magnesium atom is replaced with a more stable, less reactive metal, such as copper or sodium. This substitution enhances the molecule's stability, making it less prone to breaking down in acidic environments and when exposed to light or heat. The copper-stabilized form is specifically known as sodium copper chlorophyllin (SCC).
Chlorophyllin's Role in the Human Body
Because it is water-soluble, chlorophyllin is much easier for the human body to absorb than natural chlorophyll. It is often used in medicine for internal deodorizing purposes, helping to reduce body and fecal odors. Some studies also suggest it has antioxidant, anti-inflammatory, and potentially antimutagenic effects, meaning it may help block the damaging effects of certain toxins and carcinogens.
Comparison Table: Chlorophyll vs. Chlorophyllin
| Feature | Chlorophyll | Chlorophyllin |
|---|---|---|
| Origin | Naturally occurring in plants and algae | Semi-synthetic derivative made from chlorophyll |
| Chemical Structure | Porphyrin ring with a central magnesium (Mg) atom and a long phytol tail | Modified porphyrin ring with central magnesium replaced by a metal like copper (Cu) and no phytol tail |
| Solubility | Oil-soluble (fat-soluble) | Water-soluble |
| Stability | Less stable; sensitive to light, heat, and acidic environments | Highly stable; resistant to degradation from light, heat, and acid |
| Absorption | Poorly absorbed by the human body | Highly bioavailable and easily absorbed by the body |
| Primary Function | Photosynthesis in plants | Dietary supplement, internal deodorant, food colorant |
| Sources | Green vegetables like spinach, parsley, and broccoli | Supplements in liquid or capsule form |
Common Applications and Uses
Natural Chlorophyll Applications
In its natural form, the most important application of chlorophyll is its fundamental role in nature. For humans, it is a key component of a healthy diet rich in fruits and vegetables, which provides a wide array of vitamins, minerals, and antioxidants. While chlorophyll supplements are marketed with numerous health claims, many are not backed by strong scientific evidence, and the best source of natural chlorophyll remains whole foods.
Chlorophyllin Supplement Applications
Chlorophyllin's water-solubility and enhanced stability make it the ideal candidate for commercial applications. It is widely used as a green food colorant (E141) in a variety of products. In the health and wellness sphere, it is sold as a supplement intended to improve overall health, aid detoxification, and act as an internal deodorant.
Conclusion: Choosing Between Chlorophyll and Chlorophyllin
The core difference lies in their nature: chlorophyll is the natural, fat-soluble plant pigment, while chlorophyllin is the semi-synthetic, water-soluble supplement derived from it. Natural chlorophyll, found abundantly in green vegetables, is poorly absorbed but comes with a host of other beneficial plant nutrients. In contrast, chlorophyllin is specifically manufactured to be more bioavailable and stable, making it effective for deodorizing and its potential health benefits as a supplement. Consumers should recognize that when they purchase 'liquid chlorophyll,' they are almost certainly buying chlorophyllin. Regardless of the form, both are tied to the undeniable health benefits of a diet rich in green plants.
