Chlorophyll offers a wide range of health benefits, from detoxification and improved blood parameters to cancer prevention and acne treatment. Its potential in alleviating allergic rhinitis and enhancing athletic performance further underscores its versatility as a health supplement. As research continues, chlorophyll may become an increasingly important component of dietary and therapeutic interventions.
Chlorophyll, the green pigment found in plants, is not only essential for photosynthesis but also offers a range of health benefits when consumed by humans. This article explores the various health benefits of chlorophyll, supported by scientific research.
Detoxification and Dioxin Excretion
Chlorophyll has been shown to play a significant role in detoxification processes. A study conducted on Wistar rats demonstrated that chlorophyll derived from Chlorella could inhibit the absorption of harmful dioxins from the gastrointestinal tract and accelerate their excretion. The study found that the fecal excretion of polychlorinated dibenzo-p-dioxin (PCDD) and polychlorinated dibenzofuran (PCDF) congeners increased significantly with the intake of chlorophyll, suggesting its effectiveness in preventing dioxin absorption via foods1.
Improvement of Blood Parameters
Chlorophyll has also been found to improve various blood parameters. Research involving male rats injected with liquid chlorophyll showed significant increases in white blood cells (WBCs), red blood cells (RBCs), hemoglobin (Hgb), and other important hematological parameters. These findings suggest that chlorophyll can enhance blood characteristics and potentially prevent anemia2.
Cancer Prevention
Chlorophyll and its derivative, chlorophyllin, have been studied for their potential in cancer prevention. In a chemoprevention trial conducted in Qidong, China, chlorophyllin was found to reduce the levels of aflatoxin-DNA adducts, which are biomarkers associated with an increased risk of liver cancer. The study reported a 55% reduction in these biomarkers among participants who consumed chlorophyllin, indicating its potential to prevent hepatocellular carcinoma and other environmentally induced cancers3 8.
Protection Against Colon Cancer
Natural chlorophyll has been shown to protect against colon cancer by preventing heme-induced cytotoxic and hyperproliferative effects in the colon. A study on rats revealed that dietary heme increased colonic cytotoxicity and cell proliferation, but the addition of natural chlorophyll inhibited these harmful effects. Interestingly, chlorophyllin did not provide the same protective benefits, highlighting the unique efficacy of natural chlorophyll4.
Acne Treatment
Chlorophyll-a has been tested as a photosensitizer in photodynamic therapy for the treatment of acne vulgaris. A randomized, single-blind study found that chlorophyll-a photodynamic therapy significantly reduced acne lesion counts, severity grades, and sebum levels compared to light-emitting diode phototherapy alone. The treatment was well-tolerated, suggesting that chlorophyll-a could be an effective and safe option for acne treatment5.
Alleviation of Allergic Rhinitis
Chlorophyll c2, extracted from Sargassum horneri, has shown promise in alleviating symptoms of seasonal allergic rhinitis. In a double-blind, placebo-controlled trial, patients who received chlorophyll c2 reported significant improvements in their symptoms compared to those who received a placebo. This suggests that chlorophyll c2 could be a potential alternative treatment for allergic rhinitis6.
Enhancement of Athletic Performance
Chlorophyll supplementation has been studied for its potential benefits in endurance athletes. A randomized, double-blind study found that prolonged intake of chlorophyll significantly increased platelet-related measures, which could positively influence endurance performance by reducing pain and fatigue. However, further research is needed to confirm these ergogenic and anti-anemic properties7.
