Chlorophyll Craze: Miracle Cure or Just Hype?

A vibrant green supplement is trending, touted by influencers for benefits ranging from clearer skin to cancer prevention; however, experts urge caution before embracing the chlorophyll craze.

Decoding Chlorophyll

Chlorophyll, the pigment responsible for plants’ green color, is vital for photosynthesis. It converts sunlight into energy, releasing oxygen. While found in leafy greens, supplements usually contain chlorophyllin, a semi-synthetic, water-soluble derivative.

Does Chlorophyll Clear Skin?

Social media showcases purported skin transformations, yet research on chlorophyll’s effect on acne and wrinkles remains inconclusive. Dr. Zain Syed told The Washington Post that the studies showed a very mild effect, nothing like what’s being portrayed online.

Moreover, studies tested topical chlorophyll, not ingested liquid, with small participant groups and no placebo controls. Some experts suggest improved skin may stem from increased water intake due to mixing supplements.

Chlorophyll and Weight Loss: What’s the Truth?

Some TikTok users call chlorophyll natural Ozempic, for its supposed weight loss benefits, but the science to back this up is limited. One study showed mice gained less weight when given chlorophyll early in life.

Cancer Prevention Potential

Chlorophyll’s antioxidant properties could neutralize free radicals, unstable molecules, that damage cells and potentially lead to cancer. Studies suggest it might bind to carcinogens in the digestive tract, blocking absorption.

Animal research indicates it may hinder cancer cell growth at typical levels. Still, some studies suggest very high doses could increase tumor risk. Most research centers on chlorophyllin, not natural chlorophyll, though scientists explore the protective potential of chlorophyll-rich diets.

Other Alleged Health Perks

Beyond skin health, weight loss, and cancer prevention, proponents claim chlorophyll boosts energy, reduces body odor, and detoxifies the blood. However, Dr. Vijaya Surampudi stated that supplement makers claim chlorophyll can do many things, but few of the claims are backed by scientific evidence.

Are There Risks?

Chlorophyll supplements generally appear safe in moderation. Side effects like diarrhea or nausea have been reported. Other effects include green stool, stomach cramps, a yellow or black tongue, or mild skin irritation. Allergic reactions, though rare, can occur.

The Verdict

Plants need chlorophyll far more than we do. It’s really not necessary for humans, advised dietitian Beth Czerwony at the Cleveland Clinic. While some benefits, like antioxidant properties, are backed by research, Czerwony advises against seeing it as a miracle cure.

A diet rich in leafy greens and other chlorophyll-containing plants offers clear benefits. To boost intake, skip the supplement and head for spinach, kale, collard greens, parsley, broccoli, green beans, and asparagus. Algae like spirulina and chlorella are also great sources.
