Before considering daily chlorophyll supplementation, it's important to consult with a healthcare professional. Information provided here is for general knowledge and should not be considered medical advice.
Chlorophyll, the pigment that gives plants their vibrant green color and is essential for photosynthesis, has become a popular dietary supplement. However, the product most people consume in liquid or pill form is not true chlorophyll but a derivative called chlorophyllin, which is more stable and water-soluble. While influencers on social media tout numerous benefits, the scientific community emphasizes that more research is needed to substantiate many of these claims.
Potential Benefits of Daily Chlorophyllin Intake
Some studies, largely small-scale or animal-based, and anecdotal reports suggest several potential positive effects of consuming chlorophyllin daily. It is important to approach these benefits with a healthy degree of caution, as they are not definitively proven in human trials.
Improved Skin Health
Research suggests that topical chlorophyllin may benefit the skin. A 2015 pilot study found that a topical chlorophyllin gel helped improve acne and reduce the appearance of large pores in subjects with mild to moderate acne. In an older study, a gel containing chlorophyllin reduced signs of photoaged skin, showing results similar to prescription tretinoin. However, evidence for skin improvement from ingested chlorophyllin is limited and less conclusive.
Detoxification and Antioxidation
Chlorophyll has long been linked to detoxification, with claims dating back to the 1950s. It is believed to bind to potential carcinogens, such as aflatoxins, helping to block their absorption. Some studies, including a human trial in China, showed that chlorophyllin consumption reduced aflatoxin-related DNA damage. Additionally, chlorophyllin exhibits antioxidant properties, helping to protect cells from damage caused by free radicals.
Blood-Building Properties
Due to its chemical resemblance to hemoglobin—the protein that carries oxygen in red blood cells—some believe chlorophyll can act as a natural blood tonic. This theory suggests it can boost red blood cell production, improving oxygen delivery and potentially increasing energy levels. A 2019 clinical trial on individuals with iron deficiency anemia showed that a supplement containing chlorophyllin was associated with improved red blood cell counts.
Potential for Weight Management
While not a magic solution, some evidence links chlorophyll to appetite control. A small 2014 study on overweight women found that those who took a green plant membrane supplement containing chlorophyll lost more weight and had fewer cravings for sweet and fatty foods compared to the control group. The mechanism may involve regulating hormones like ghrelin, the 'hunger hormone'.
Body and Breath Deodorizer
One of the most persistent claims about chlorophyll is its ability to reduce body and breath odor. This idea dates back decades, though scientific evidence is scarce and often outdated. The deodorizing effect is thought to occur from chlorophyllin's internal cleansing properties, though more rigorous, modern studies are needed.
Potential Risks and Side Effects
While generally considered safe for most people when taken in moderation, daily chlorophyllin supplementation can lead to some side effects. The most common are related to the digestive system, but other issues can arise.
- Digestive Discomfort: Nausea, vomiting, stomach cramps, and diarrhea are possible, especially when starting a new supplement. Taking the supplement with food may help mitigate these effects.
- Discolored Waste: The green pigment can temporarily turn urine and stools a greenish color, which is harmless but can be startling. In some cases, it can cause the tongue to appear yellow or black.
- Photosensitivity: Daily intake may increase sensitivity to sunlight, raising the risk of sunburn. Individuals should use caution and consider protective measures, particularly during sun exposure.
- Medication Interactions: Chlorophyllin can potentially interact with some medications, including those that increase sun sensitivity or certain chemotherapeutic drugs like methotrexate. Always consult a doctor before beginning a new supplement, especially if you are on medication.
- Lack of FDA Regulation: As a dietary supplement, chlorophyllin is not regulated by the FDA in the same way as drugs. This means product purity, concentration, and claims are not guaranteed by a governing body.
Natural Chlorophyll vs. Chlorophyllin Supplements
For those interested in boosting their chlorophyll intake, the most reliable and safest method is through whole foods. Green vegetables provide natural chlorophyll alongside a host of other beneficial nutrients that work synergistically in the body.
Comparison Table: Supplement vs. Whole Foods
| Feature | Chlorophyllin Supplement | Whole Food (e.g., Spinach) | 
|---|---|---|
| Form | Water-soluble derivative (chlorophyllin) | Naturally occurring chlorophyll | 
| Absorption | Enhanced absorption due to modification | Lower bioavailability, but part of a nutrient complex | 
| Additional Nutrients | Primarily isolated compound, may contain fillers | Abundant fiber, vitamins, and minerals | 
| Regulation | Not strictly regulated by the FDA | Naturally occurring, regulated as food | 
| Cost | Can be expensive for daily use | Generally more affordable and nutrient-dense | 
| Side Effects | Potential for digestive upset, photosensitivity | No known side effects in moderate amounts | 
Chlorophyll-Rich Foods to Add to Your Diet

Conclusion: Informed Choices for Daily Health
If you take chlorophyll daily, you are likely consuming chlorophyllin, not natural chlorophyll, and may experience some mild side effects such as digestive issues or discolored waste. While there are many anecdotal stories and limited preliminary research suggesting benefits like better skin, detoxification, and appetite control, these claims lack robust scientific backing from large-scale human studies. Furthermore, daily supplementation can carry risks, including potential drug interactions and increased sun sensitivity, and is not recommended for pregnant or breastfeeding women due to lack of research. Ultimately, the safest and most nutrient-rich way to boost your chlorophyll intake is by eating a variety of leafy green vegetables, which provide a complete package of vitamins, minerals, and fiber that supplements cannot replicate. As with any new supplement, it is wise to consult a healthcare provider before adding chlorophyllin to your daily regimen.
