The recent trend of adding liquid chlorophyll to water has led to many claims about its health benefits, including improved skin and body detoxification. A specific claim that has gained popularity is that this liquid supplement acts as a gentle laxative, promoting more frequent and regular bowel movements. This inquiry seeks to determine the scientific basis for the digestive effects of the green pigment, chlorophyll, sold in stores.
The Chemical Difference Between Chlorophyll and Chlorophyllin
The substance purchased in liquid supplements is not natural chlorophyll, which is the compound found in leafy greens. Natural chlorophyll contains a central magnesium atom and is fat-soluble, meaning it is poorly absorbed by the human body in its raw state. To create a product suitable for supplement use, the chlorophyll molecule undergoes a chemical process called saponification. This process replaces the central magnesium atom with a less reactive metal, typically copper, and adds sodium salts, resulting in a semi-synthetic derivative called chlorophyllin.
This chemical alteration makes chlorophyllin water-soluble and far more stable, which is why it is used in liquid and tablet forms. The improved stability and water solubility increase the compound’s bioavailability, allowing for easier absorption after use. Therefore, any potential digestive or systemic effects observed from supplements are due to this modified compound, chlorophyllin, and not the natural pigment found in vegetables.
Scientific Analysis of Digestive Effects
The belief that chlorophyllin aids bowel regularity stems largely from anecdotal reports and some limited, older research. One study, conducted on elderly nursing home patients, suggested that chlorophyllin tablets helped ease chronic constipation and reduced fecal odors. However, modern, large-scale, placebo-controlled clinical trials specifically proving chlorophyllin’s efficacy as a treatment for chronic constipation are currently lacking.
Some proponents hypothesize a mild laxative effect may be related to the compound’s structure or its general impact on the gut, though the exact mechanism remains unproven. It is also possible that a perceived benefit is simply the result of consuming more water, as the supplement is mixed into a liquid, and increased hydration is a known factor in softening stool. A common side effect of chlorophyllin consumption is gastrointestinal upset, which can include loose stools or diarrhea. This suggests that for some individuals, the compound may accelerate gut motility.
Safety Profile and Consumption Guidelines
Chlorophyllin is generally considered safe for short-term consumption, but it is not without some practical considerations and side effects. The most common noticeable effect is the harmless green discoloration of urine and stools, which can be mistaken for intestinal bleeding. Mild gastrointestinal issues, such as stomach cramps, nausea, or loose stools, are also frequently reported, particularly when starting the supplement.
A more serious concern is the potential for photosensitivity, where the skin becomes more sensitive to sunlight, increasing the risk of sunburn. Individuals taking chlorophyllin should use appropriate sun protection, including sunscreen and protective clothing, when outdoors. Due to the lack of sufficient safety data, people who are pregnant, breastfeeding, or administering the supplement to children should consult a healthcare professional. Furthermore, high doses over extended periods may present a risk of copper toxicity because of the copper atom integrated into the chlorophyllin molecule.
Established Dietary Approaches for Regularity
For individuals seeking reliable methods to support regular bowel movements, established dietary and lifestyle changes remain the primary approach. The most effective strategy involves increasing the intake of dietary fiber, with health authorities recommending approximately 25 grams daily for women and 31 to 38 grams for men.
Fiber is categorized into two types, both of which support regularity. Insoluble fiber, found in the skins of fruits, leafy greens, and whole grains, adds bulk to the stool, helping it pass more quickly through the digestive tract. Soluble fiber, present in oats, beans, and apples, absorbs water to form a gel-like substance, which softens the stool and makes it easier to pass.
Pairing a high-fiber diet with adequate fluid intake is necessary, as water prevents the fiber from hardening and causing further constipation. Regular physical activity also stimulates the muscles of the intestines, contributing to healthy gut motility.
