Natural Chlorophyll vs. Chlorophyllin
Chlorophyll, in its natural state found in leafy greens and vegetables, is a fat-soluble molecule that the human body absorbs very poorly. In supplement form, manufacturers use a modified, semi-synthetic version called chlorophyllin. This version has its central magnesium atom replaced with copper or other metals and is made water-soluble through a process called saponification, which also removes the phytol tail. The result is a much more stable and bioavailable compound that the body can use more effectively than the natural pigment.
It's important to recognize that when you purchase “liquid chlorophyll,” you are almost always buying a chlorophyllin supplement, not the natural chlorophyll found in plants. For therapeutic uses, such as reducing body odors, chlorophyllin is the form that has been used in clinical settings for decades.
Comparing Chlorophyll Supplement Forms
Chlorophyllin, the primary form of supplemental chlorophyll, is available in several formats. The best option for you will depend on your preferences for convenience, taste, and lifestyle.
-
Liquid Drops: Arguably the most popular form, liquid drops are a concentrated version of chlorophyllin meant to be mixed with water or other beverages.
- Pros: Potentially faster absorption rate than capsules, and can be added to various drinks.
- Cons: Can stain clothing, and the flavor (often minty) may not be for everyone, especially if the product contains sweeteners or preservatives.
-
Capsules or Tablets: These offer a convenient, mess-free, and tasteless way to take chlorophyllin, especially for those who dislike the taste of the liquid.
- Pros: Highly convenient for on-the-go use and for those who prefer not to taste it.
- Cons: Absorption may be slower than liquid, and the capsule or tablet casing might contain fillers or other ingredients.
-
Powder: Similar to liquid drops, powdered chlorophyllin can be mixed into water, smoothies, or other drinks.
- Pros: Allows for precise dosing and easy integration into recipes.
- Cons: Requires mixing, which can be less convenient than a capsule. Quality and concentration can vary.
Chlorophyll Supplement Forms Comparison
| Feature | Liquid Drops (Chlorophyllin) | Capsules/Tablets (Chlorophyllin) | Natural Chlorophyll (from foods) |
|---|---|---|---|
| Absorption | Potentially faster. | Slower, requires digestion. | Poorly absorbed by the body. |
| Convenience | Less convenient due to mixing and potential for mess. | Very convenient and portable. | Requires food preparation. |
| Taste | Often has a minty or earthy taste. | Flavorless, easy to swallow. | Depends on the vegetable source. |
| Bioavailability | High bioavailability due to modification. | High bioavailability, but may have a delayed effect. | Very low bioavailability. |
| Nutrient Profile | Isolated compound, no additional nutrients. | Isolated compound, no additional nutrients. | Comes with fiber, vitamins, and minerals. |
The Case for Whole Foods: Chlorophyll from Nature
While chlorophyllin supplements offer a highly absorbable form of the compound, the most effective and safest way to increase your chlorophyll intake is through whole foods. Green leafy vegetables, algae, and other green plants contain natural chlorophyll in abundance, alongside a symphony of other health-promoting nutrients.
Here are some excellent food sources of chlorophyll:
- Dark Green Leafy Vegetables: Spinach, kale, parsley, and collard greens are packed with chlorophyll.
- Other Green Veggies: Broccoli, asparagus, green beans, and peas also contain notable amounts.
- Algae and Wheatgrass: Spirulina and chlorella are extremely rich sources of chlorophyll, often sold in supplement form as well. Wheatgrass juice is also notably high in the pigment.
Eating a variety of colorful fruits and vegetables provides a wider spectrum of phytochemicals and antioxidants, which many experts believe work synergistically to provide the greatest health benefits.
Understanding the Evidence Behind Chlorophyll Benefits
Much of the enthusiasm for chlorophyll supplements is fueled by limited, preliminary research and anecdotal evidence. While chlorophyll and chlorophyllin possess antioxidant properties, the clinical evidence for many purported benefits is either limited or awaiting further investigation in large-scale human trials. Claims regarding weight loss, for instance, are based on very small studies and animal research.
On the other hand, a few potential benefits have shown some promise in research:
- Internal Deodorant: Chlorophyllin has been used for over 50 years to help control body odor, particularly in individuals with certain medical conditions.
- Skin Healing: Topical chlorophyllin ointments have shown potential in small studies to aid in wound healing, reduce inflammation, and improve sun-damaged skin and acne.
- Chemoprevention: Animal studies and a small human trial suggest chlorophyllin may help block the absorption of certain cancer-causing agents, like aflatoxins.
It's crucial to manage expectations, understanding that supplement benefits are often overstated and that whole-food sources provide broader nutritional advantages.
How to Choose the Right Chlorophyll Product
If you decide to take a chlorophyllin supplement, informed choices are essential. Given that supplements are not tightly regulated by the FDA, a discerning eye is necessary to ensure safety and quality.
- Look for Third-Party Testing: Seek brands that have been independently tested for purity and potency by organizations like NSF International or U.S. Pharmacopeia (USP). This provides peace of mind regarding the product's quality.
- Check the Source: Note the source of the chlorophyllin, such as alfalfa or mulberry. The source doesn't necessarily affect the final chlorophyllin product, but it can be a marker of overall brand quality.
- Consider Your Lifestyle: Choose between liquid, capsule, or powder based on what fits best into your daily routine. Do you prefer adding it to a morning drink or a simple, no-fuss pill?
- Consult a Healthcare Professional: Always speak with a doctor or a registered dietitian before starting any new supplement, especially if you have existing health conditions or take other medications.
Safety and Potential Side Effects
Chlorophyllin is generally considered safe for most people. However, some potential side effects have been reported, particularly with oral supplementation. These can include:
- Gastrointestinal issues, such as diarrhea or nausea.
- Green, yellow, or black discoloration of urine and feces.
- Topical applications may cause mild burning or itching.
There is insufficient safety research for pregnant or lactating women, who should avoid commercial supplements. It is always best to prioritize whole food sources and only use supplements under professional guidance.
Conclusion
When considering what is the best form of chlorophyll to take, the answer depends on your goals. For robust nutrient intake, natural chlorophyll from a variety of dark green vegetables is the superior option, providing fiber, vitamins, and minerals that supplements lack. However, if you are seeking the potential therapeutic benefits of a supplement, a chlorophyllin product is the correct choice due to its superior stability and absorption. Both liquid and capsule forms of chlorophyllin are available, with the best one being a matter of personal preference regarding taste and convenience. Regardless of your choice, prioritizing a balanced, whole-food diet is the most effective strategy for promoting overall health and wellness.
