Chlorophyll is the green pigment found in plants, algae, and some bacteria, playing a fundamental role in photosynthesis, the process by which plants convert sunlight into energy. While chlorophyll is naturally present in all green vegetables, the concentrated products sold commercially are the focus of a wellness trend. The general safety profile of these supplements is good, though it is important for consumers to understand the difference between the natural compound and the derivative used in most products.
Understanding Chlorophyll Supplement Forms
The majority of commercial supplements marketed as “chlorophyll” do not contain the natural compound but instead use a semi-synthetic, water-soluble derivative called chlorophyllin. Natural chlorophyll is fat-soluble and possesses a magnesium atom at its core, but it is chemically unstable and poorly absorbed when consumed orally. This makes the natural form less practical for mass-produced supplements.
Chlorophyllin is created through an industrial process that replaces the central magnesium atom with copper or sodium, resulting in a more stable and water-soluble compound. This modification significantly enhances the product’s stability and absorption in the body, making it the standard ingredient in liquid drops and capsules. Supplements are most commonly sold as liquid drops, mixed into water, or as convenient tablets and capsules. Liquid forms are often preferred for perceived faster absorption, while capsules provide a less messy, more portable option.
The Health Claims Behind Buying Chlorophyll
Internal deodorization is one of the longest-standing claims motivating people to buy chlorophyll supplements. Chlorophyllin has been used for over 50 years as an internal deodorant, historically to reduce odor from colostomies and fecal incontinence. Consumers today use it to help neutralize compounds that cause body odor and bad breath. This property is thought to work by acting on the digestive tract.
The supplement is also popular for benefits to skin health, with many users seeking it out for help with acne and clarity. Topical application of chlorophyllin has been studied for minor wound healing, and it is sometimes included in products that promote antioxidant properties to fight cell damage. The claims often include “detoxification” benefits, suggesting the compound aids the liver’s ability to eliminate toxins and waste from the body. It is important to note that while the structure of chlorophyll is similar to hemoglobin, the molecule in red blood cells, research supporting these human health benefits is still limited.
Safe Consumption and Potential Side Effects
While chlorophyllin is generally considered safe for consumption, following the product’s label directions is important, as there are no official standardized dosage guidelines. Most products recommend a dosage in the range of 100 milligrams of chlorophyllin per day. It is always advisable to discuss any new supplement with a healthcare provider, especially if you are taking prescription medications.
Some mild side effects are possible, most commonly involving the digestive system. These can include stomach upset, mild diarrhea, or loose stools, which usually resolve after discontinuing use. Because chlorophyllin is a strong pigment, it may cause a harmless, temporary green or yellow discoloration of the urine and stool. Increased sensitivity to the sun, known as photosensitivity, is a potential warning that increases the risk of sunburn. Chlorophyllin can also interfere with certain medical lab tests, such as the guaiac card test for occult blood, leading to false-positive results.
