Chlorophyll: Health Benefits, Myths, and Science Behind the Green Pigment
Experts say more greens matter than miracle drops alone.
Known for giving plants their vibrant green hue, chlorophyll has recently emerged in wellness circles as a trendy supplement. Promoted for everything from clearer skin to improved detoxification, this plant pigment is now found in drops, capsules, juices, and topical cosmetics. However, sorting fact from hype requires a closer look at its real health impacts and what science says about its purported benefits.
What is Chlorophyll?
Chlorophyll is a naturally occurring pigment in green plants, algae, and certain bacteria. It plays an essential role in photosynthesis, helping plants convert sunlight, carbon dioxide, and water into energy. In humans, interest in chlorophyll has shifted toward its potential health properties, with supplements marketed as a way to harness these effects.
Why is Chlorophyll Suddenly Popular?
Recently, social media influencers and wellness brands have spotlighted chlorophyll as a ‘superfood’ ingredient. Videos of strikingly green drinks and testimonials about clearer skin, increased energy, and better digestion have driven consumer demand. Some brands claim chlorophyll can ‘detox’ the body, balance the lymphatic system, and even act as a natural deodorant.
- Products like Detox Water Drops and concentrated chlorophyll tinctures have flooded the market.
- Advocates tout chlorophyll for a wide range of wellness benefits, though not all claims have robust scientific support.
Potential Health Benefits of Chlorophyll
1. Acne and Skin Health
One of the most common uses for chlorophyll is topical and oral application for skin clarity. Some small studies have shown potential:
- A 2015 pilot study found that applying chlorophyllin gel for three weeks led to mild to moderate improvements in acne and a reduction in pore size in ten adults.
- Another study observed benefits for sun-damaged skin when topical chlorophyllin was applied for eight weeks.
- These effects may stem from chlorophyll’s antioxidant and anti-inflammatory properties.
However, these studies were small and larger, controlled trials are needed to confirm benefits. Dermatologists note that chlorophyll’s anti-inflammatory actions could help reduce redness and support skin healing, but evidence remains limited.
2. Anti-Aging Properties
Beyond acne, chlorophyll has been tested in anti-ageing research:
- Topical chlorophyllin used alongside tretinoin (a proven anti-aging prescription cream) improved the appearance of photoaged skin.
- Researchers concluded the combination could be effective for reversing some signs of sun damage, such as fine lines and skin roughness, but larger studies are still required.
3. Gut Health and Digestion
Some supplement makers claim chlorophyll aids gut health and supports digestion.
What others are reading
- Animal and early human research suggests chlorophyll or related compounds may help modulate the gut microbiota and reduce inflammation in the digestive tract.
- One study found that supplementation with chlorophyll-rich extracts improved gut microbial diversity in mice and had possible anti-obesity effects.
Experts note that while chlorophyll is present in dietary sources like spinach and parsley, its impact on human digestion via supplements requires more research.
4. Boosting Energy and Supporting Blood Function
Many chlorophyll products claim to support energy levels and help the blood carry oxygen.
- This idea is partly based on the chemical structure of chlorophyll, which resembles hemoglobin (the oxygen-carrying molecule in human blood).
- Some animal model studies suggest it could have a positive effect, but these findings have not been robustly confirmed in human clinical trials.
5. Liver Health and Detoxification
Chlorophyll is often advertised for its ‘detoxifying’ properties, particularly supporting liver function:
- Research indicates that chlorophyll can bind to certain toxins and aid in their elimination from the body.
- This has been explored regarding aflatoxin (a poison from molds) and other environmental contaminants, and may help the liver manage these toxins.
- Some studies show chlorophyll supports the body’s natural detoxification pathways, mainly by boosting liver enzymes.
However, the evidence for using chlorophyll supplements specifically for general ‘detox’ is still modest.
6. Anti-Inflammatory and Antioxidant Effects
Chlorophyll and its derivatives may offer some antioxidant protection and could help reduce inflammation in the body:
- By scavenging free radicals, chlorophyll helps mitigate oxidative stress, a key factor in inflammation and chronic illnesses.
- Animal studies and some laboratory data support these effects, though human trials are limited.
- Other dietary antioxidants, such as vitamins C and E, remain much stronger on a per-dose basis.
7. Reducing Body Odors
Chlorophyllin, a semi-synthetic derivative of chlorophyll, has been used as an internal deodorant.
- Historically, it was prescribed for patients with foul-smelling wounds and ostomies, and limited modern research still supports mild deodorizing effects.
- However, scientific evidence for oral chlorophyllin as a deodorant is sparse, and improvements tend to be modest.
8. Cancer-Fighting Properties and Weight Loss Claims
There are persistent claims that chlorophyll may help prevent or slow cancer development and promote weight loss.
- Some laboratory and animal studies indicate chlorophyll could protect against certain carcinogens by binding and eliminating them from the digestive system.
- At present, there is insufficient evidence from large, long-term human studies to recommend chlorophyll for cancer prevention or as a weight-loss supplement.
How to Add Chlorophyll to Your Diet
There are two main ways to get more chlorophyll:
- Eating green vegetables: Spinach, parsley, broccoli, and green beans are naturally rich sources.
- Supplements: Liquid chlorophyll drops, capsules, and powders are widely available. Note that many supplements use chlorophyllin, a more water-soluble and stable form.
Table: Common Sources of Chlorophyll
| Food or Supplement | Chlorophyll Content |
|---|---|
| Spinach (cooked, 1 cup) | 23.7 mg |
| Parsley (fresh, 1/2 cup) | 19 mg |
| Liquid drops (per dose) | Varies (ranges from 15–100 mg) |
| Green powders (per scoop) | Varies by formulation |
Chlorophyll Supplements: What to Know Before Trying
Although supplementing with chlorophyll is generally considered safe for most people, certain precautions and potential side effects should be noted:
- Possible Side Effects: Digestive upset (nausea, diarrhea, green discoloration of stool), mild cramping, and (rarely) allergic reactions.
- Sun Sensitivity: Some evidence suggests that large doses might increase the skin’s sensitivity to sunlight, potentially raising the risk of sunburn.
- Medication Interactions: People taking medications or those with chronic health conditions should consult their healthcare provider before starting supplements.
- The FDA does not regulate supplements as stringently as medications, so dose consistency and purity can vary.
Myths and Misconceptions
The growing popularity of chlorophyll has led to many unsubstantiated claims. It is not a cure-all, and in most cases, benefits are either preliminary, modest, or based on minimal evidence.
- There is little human research supporting chlorophyll as a significant energy booster, cancer fighter, or rapid skin cure.
- Many effects may be due to the consumption of more leafy greens overall, rather than chlorophyll alone.
- Dietary sources of chlorophyll come with added fiber, vitamins, and minerals that contribute to better general health.
What Experts Say
Dietitians and dermatologists agree that while chlorophyll may offer minor antioxidant and anti-inflammatory benefits, it should not replace evidence-based therapies or whole-food nutrition.
- Registered dietitians rank chlorophyll-rich foods among the healthiest dietary choices but caution against viewing supplements as a panacea.
- “Chlorophyll has certain antioxidants and potential anti-inflammatory benefits such as skin healing; however, larger studies are needed to further evaluate its potential health benefits,” notes one expert cited in scientific reviews.
Frequently Asked Questions About Chlorophyll
What is the difference between chlorophyll and chlorophyllin?
Chlorophyll is the natural pigment in plants, while chlorophyllin is a semisynthetic, more stable and water-soluble form often used in supplements and topical products. Chlorophyllin may be better absorbed by the body but differs slightly in chemical structure from pure chlorophyll.
Can taking chlorophyll clear up my acne?
Small studies suggest topical or oral chlorophyll or chlorophyllin may reduce mild to moderate acne and improve skin appearance, largely due to their anti-inflammatory effects. However, larger clinical trials are needed for confirmation, and results may vary between individuals.
Are chlorophyll drops safe to drink every day?
For most healthy adults, moderate use of chlorophyll or chlorophyllin supplements is considered safe and may cause only mild side effects like green stool or minor digestive upset. Consult a healthcare provider before taking regularly, especially if you have any underlying health conditions or are on medication.
Does chlorophyll detox your body?
Chlorophyll may help the body bind and eliminate some toxins, particularly in the digestive tract and via liver support. However, quality evidence for using supplements specifically as a ‘detox’ method is limited. Eating a balanced diet rich in whole foods remains the best strategy for supporting the body’s natural detoxification systems.
Can chlorophyll supplements be harmful?
High doses could increase sun sensitivity and risk of adverse effects, and supplements can be contaminated or inconsistent in quality. Rare allergic or gastrointestinal reactions can occur. Always consult with a physician if you are on medication, pregnant, or have chronic health concerns.
Key Takeaways
- Chlorophyll is essential for plant health and may have limited health benefits for humans.
- Some evidence supports minor effects on skin clarity, gut health, and detoxification, but claims about anti-cancer and major weight loss effects are unproven.
- The safest way to consume chlorophyll is through a diet high in green, leafy vegetables.
- Supplements are generally safe but can cause digestive upset and should be taken with caution, especially in high doses.
- Consult a professional if considering chlorophyll for specific health conditions.
Always rely on a balanced diet and professional medical advice rather than social media trends alone.
