Chlorophyll is the pigment that gives plants their vibrant green color and is essential for photosynthesis. When people talk about taking chlorophyll as a supplement, they are most often referring to chlorophyllin, a water-soluble, semi-synthetic derivative used in commercial products. While many claims circulate online, it is important to scrutinize them based on scientific evidence. This article breaks down the potential advantages and disadvantages of adding chlorophyll to your wellness routine.
The Pros of Taking Chlorophyll: Potential Benefits
Antioxidant and Anti-inflammatory Properties
Like many plant-based compounds, chlorophyll and chlorophyllin possess antioxidant properties that may help combat oxidative stress caused by free radicals. This anti-inflammatory potential is a key factor behind many of its proposed health benefits. Early research suggests that these properties may protect cells from damage, contributing to overall health.
Potential Skin Health Improvements
Several small-scale pilot studies have investigated the use of topical chlorophyllin gel for skin conditions. These studies showed some improvement in mild-to-moderate acne, large pores, and skin damage from sun exposure. It is important to note that these benefits were observed with topical application, not oral supplementation, and that larger, more rigorous studies are needed.
Detoxification Support
Chlorophyll has been studied for its ability to bind to certain carcinogens, such as aflatoxins, which may reduce their absorption in the gut. This suggests a possible role in supporting the body's natural detoxification processes, particularly concerning certain toxins. Some believe it also helps with general cleansing, but more research is required to fully understand the mechanisms and effectiveness.
Natural Deodorizing Effects
Since the mid-20th century, chlorophyllin has been explored as a natural deodorizer. Some anecdotal evidence and older studies suggest it may help reduce body odor and combat bad breath, though modern, strong scientific evidence is still lacking. It has been used to help control odors in patients with ostomies and other conditions.
The Cons of Taking Chlorophyll: Risks and Side Effects
Mild Digestive Distress
One of the most common side effects of taking chlorophyll, especially in liquid form or high doses, is mild digestive upset. This can include:
- Diarrhea
- Nausea
- Stomach cramps
- Loose stools
Discoloration of Stools and Skin
Users of chlorophyll supplements often notice a harmless discoloration of their stools, urine, or even their tongues (often green, yellow, or black). While harmless, this can be confused with gastrointestinal bleeding. In rare cases, skin discoloration has also been reported.
Potential Photosensitivity
There is a risk that taking chlorophyll supplements could increase your skin's sensitivity to sunlight, making you more prone to sunburn. This is due to chlorophyll's nature as a photosensitizer. It's advisable to use sun protection if you are supplementing with chlorophyll.
Medication Interactions and Safety Concerns
Chlorophyll can potentially interact with certain medications, affecting their effectiveness. For example, it is known to prolong the clearance of the chemotherapy drug methotrexate from the body. Individuals with kidney problems or those who are pregnant or breastfeeding should consult a doctor before use, as safety has not been established for these groups.
Limited Scientific Evidence
Despite the enthusiasm on social media, the scientific evidence supporting many of the health claims for oral chlorophyll supplementation is limited, outdated, or based on small-scale studies. Much of the promising research has been conducted in test tubes or on animals, which does not guarantee the same effects in humans. Experts often suggest that obtaining chlorophyll naturally from green vegetables is a more effective and beneficial approach, as it comes with other essential nutrients and fiber.
Chlorophyll vs. Chlorophyllin: A Key Distinction
It's important to differentiate between natural chlorophyll from whole foods and the supplement form, chlorophyllin. Here’s a quick comparison:
| Feature | Natural Chlorophyll (from food) | Chlorophyllin (in supplements) |
|---|---|---|
| Source | Found in leafy green vegetables like spinach, kale, and parsley | A water-soluble derivative of chlorophyll processed with copper and sodium |
| Absorption | Can be poorly absorbed by the human body | Water-soluble and contains copper to enhance absorption |
| Nutrient Profile | Comes with fiber, vitamins, and minerals | Lacks the additional nutrients and fiber found in whole foods |
| Side Effects | Not known to cause side effects, even in large quantities | Can cause digestive issues and discoloration of waste |
Conclusion
While taking chlorophyll, particularly in its chlorophyllin supplement form, might offer some potential benefits like antioxidant support, detoxification, and natural deodorizing effects, the scientific evidence for many of these claims remains limited and often based on small studies. The best way to increase your chlorophyll intake is by consuming plenty of green vegetables, which provide a broader range of nutrients and fiber. If you choose to use a supplement, be aware of the potential for mild side effects like digestive upset and discoloration. Always consult with a healthcare provider before starting any new supplement, especially if you have pre-existing conditions or are on medication. For more information, you can explore detailed reports on specific studies and findings, but it is important to remain mindful of the often-limited scope of the research and the general recommendation to prioritize a nutrient-dense, plant-rich diet.
