Common Gastrointestinal Side Effects
One of the most frequently reported side effects of taking oral chlorophyll supplements is gastrointestinal distress. The sudden increase of a new substance in the digestive system can lead to a variety of uncomfortable symptoms, which are often mild and temporary.
Diarrhea and Upset Stomach
Many people experience loose stools or even diarrhea when they first start taking chlorophyllin, the water-soluble form found in most supplements. This is often due to the body adjusting to the new supplement and typically subsides with time or a reduced dosage. Stomach cramps and general nausea are also not uncommon, especially when taking higher doses. Starting with a smaller dose and gradually increasing it can help minimize these digestive issues.
Discoloration of Waste
Another harmless, yet often startling, side effect is the discoloration of bodily waste. Chlorophyll's powerful green pigment can turn urine and feces a green, yellowish, or even black color. This can be alarming and potentially mistaken for gastrointestinal bleeding, but it is a temporary and normal result of the supplement.
Skin and Sun Sensitivity
Chlorophyll supplements can also affect your skin, both internally and externally. This is primarily due to chlorophyllin's photosensitizing properties, which increase sensitivity to sunlight.
Increased Risk of Sunburn
Taking chlorophyllin can make your skin more prone to sunburn. It is crucial to be more vigilant about sun protection, such as wearing sunscreen and protective clothing, especially during peak hours. This effect can be more pronounced in individuals already taking medications that increase photosensitivity.
Topical Irritation
For those who use chlorophyll topically in ointments or gels, mild skin irritation, including itching or a burning sensation, can occur. It is recommended to perform a patch test on a small area of skin before applying it widely to check for any adverse reaction.
Potential Drug Interactions and Risks
While chlorophyll is generally considered safe for most people, there are important precautions to consider, especially concerning medication interactions and specific health conditions.
Medication Interactions
Chlorophyllin can interact with certain medications, potentially affecting their effectiveness. A significant interaction has been noted with methotrexate, a drug used to treat conditions like psoriasis and rheumatoid arthritis, as chlorophyll may prolong its presence in the body. If you are on any medication, consulting a doctor before starting a chlorophyll supplement is essential.
Pregnant and Breastfeeding Individuals
There is a lack of sufficient research on the safety of chlorophyll supplements for pregnant or breastfeeding women. Health experts advise against taking it during these periods to avoid potential risks to the unborn baby or infant.
Allergic Reactions
Although rare, allergic reactions to chlorophyllin supplements are possible. Symptoms could include hives, swelling, or difficulty breathing. Discontinue use and seek medical attention if any signs of a severe reaction occur.
Natural Chlorophyll vs. Supplemented Chlorophyllin
It is important to distinguish between the chlorophyll found in whole foods and the chlorophyllin in supplements.
| Feature | Natural Chlorophyll (from food) | Chlorophyllin (from supplements) |
|---|---|---|
| Source | Green vegetables (spinach, kale, parsley) | Synthetically derived, water-soluble form |
| Absorption | Poorly absorbed by the body | Enhanced absorption due to added copper and sodium |
| Risks | No known side effects in large amounts | Potential for gastrointestinal issues, sun sensitivity |
| Additional Nutrients | Provides fiber, vitamins, and minerals | Typically isolated and lacks additional nutritional benefits |
| Purity | Purity is guaranteed as part of whole food | Varies, as supplements are not FDA-regulated |
Conclusion: Weighing the Risks and Benefits
What are the side effects of chlorophyll? For most people, the side effects of chlorophyll are mild and include temporary digestive issues and skin sensitivity. The risks are generally low, especially when taken in moderation. However, interactions with certain medications and increased sun sensitivity are significant considerations. The key takeaway is that for a person with a healthy diet rich in green vegetables, supplemental chlorophyll may not be necessary to reap its purported benefits. For those who choose to supplement, starting with a low dose and consulting a healthcare provider, particularly if pregnant, breastfeeding, or on medication, is the most prudent approach. The healthiest and safest way to increase your chlorophyll intake is by incorporating more leafy greens and other plant-based foods into your daily routine.
List of Foods Rich in Natural Chlorophyll
- Spinach: A powerhouse of nutrients and chlorophyll.
- Parsley: Often used as a garnish, it's packed with chlorophyll.
- Kale: A popular superfood with high chlorophyll content.
- Collard Greens: Another leafy green with excellent nutritional value.
- Wheatgrass: Very high in chlorophyll, often consumed as a shot.
- Green Beans and Peas: Excellent sources that can be easily added to meals.
- Arugula: A peppery green with significant chlorophyll.
When to Consult a Healthcare Provider
- Before starting any new supplement, especially if you are on other medications.
- If digestive issues like diarrhea or nausea persist.
- If you experience an allergic reaction.
- If you notice changes in your stool or urine that persist, or are concerning, despite stopping the supplement.
- If you are pregnant or breastfeeding.

Conclusion
While chlorophyll supplements are widely marketed for various health benefits, a clear understanding of the potential side effects and risks is crucial. The mild gastrointestinal upset, skin sensitivity, and discoloration of bodily waste are generally manageable. More serious concerns involve potential drug interactions and safety for specific populations like pregnant and breastfeeding women, where research is lacking. By favoring natural, food-based sources of chlorophyll over unregulated supplements, most individuals can safely reap potential benefits while minimizing risks. Always consult a healthcare professional before adding any new supplement to your regimen.
Final Summary of Chlorophyll Side Effects
Chlorophyll supplements can cause side effects ranging from mild digestive upset and harmless discoloration of waste to more notable sun sensitivity and potential drug interactions. The synthetic form, chlorophyllin, is most commonly associated with these effects. Topical use may cause mild irritation. Caution is advised for pregnant or breastfeeding women, and those on specific medications should consult a doctor before use.

Important Safety Considerations
It's important to remember that dietary supplements are not regulated by the FDA in the same way as medications. This means that the quality, purity, and concentration of active ingredients can vary significantly between brands. Always choose a reputable brand and follow recommended dosages carefully. If in doubt, prioritize natural sources of chlorophyll through a balanced diet.
