Chlorophyll's Health Benefits Spark Interest—but Experts Urge Caution

Chlorophyll, the green pigment essential for plant photosynthesis, has gained attention for its potential health benefits. Found in supplements and topical treatments, it is often promoted for reducing inflammation, aiding weight loss, and improving skin conditions. However, experts remain cautious about its widespread use in supplement form. Chlorophyllin, a semi-synthetic form derived from chlorophyll, is commonly used in dietary supplements. Research suggests it may help reduce inflammation, particularly in conditions like inflammatory bowel disease (IBD). Some small studies also indicate that chlorophyllin ointments could improve wound healing and skin issues, including acne and sun damage.

A study on a green plant membrane supplement containing chlorophyll reported increased weight loss among participants. Additionally, chlorophyll is known for its antioxidant and anti-inflammatory properties, which contribute to its growing popularity. Despite these findings, registered dietitian Beth Czerwony advises against taking chlorophyll supplements. While they appear safe in moderation, possible side effects include mild stomach discomfort, discoloured stools, and an increased risk of sunburn. The Cleveland Clinic, however, does not endorse any non-Cleveland Clinic products or services, including these supplements.

Chlorophyll shows promise in certain health applications, particularly in reducing inflammation and aiding skin recovery. Yet, experts like Czerwony urge caution, noting that more research is needed before widespread recommendations can be made. For now, its use remains limited to specific, carefully studied cases.
