What is chlorophyll?
Chlorophyll is the green pigment present in all plants and various algae , vital for the process of photosynthesis. Thanks to it, plants can transform solar energy into chemical energy, allowing them to produce their own food and release oxygen, essential for life on Earth. In addition to its biological role, chlorophyll is notable for its molecular structure, very similar to the hemoglobin in human blood, although instead of iron, the central atom of chlorophyll is magnesium.
This similarity has attracted the attention of the scientific community, sparking interest in exploring its potential effects on human health. Therefore, both natural chlorophyll and chlorophyllin (a water-soluble derivative used in supplements) have been the subject of numerous studies. Chlorophyllin is used because it is more stable and easily absorbed by the body than pure chlorophyll.
Chlorophyll is currently trending in the wellness and nutrition world, appearing not only in beverages and supplements, but also in cosmetic applications and general wellness products.
Natural sources of chlorophyll
Green vegetables are the main source of chlorophyll for humans . The more intense the green color of a plant, the higher its concentration of this pigment. Some of the foods richest in chlorophyll include:
- Spinach (rich in chlorophyll and easy to incorporate into salads and smoothies)
- Parsley (excellent for green juices and dressings)
- Lettuce, Red Lettuce
- Watercress
- Chard
- Kale
- Arugula
- Cilantro
- Asparagus
- Green peppers
- Celery
- Algae (spirulina, chlorella)
Other foods such as spirulina and chlorella are valued in functional nutrition for their high chlorophyll and other nutrient content, and can complement a balanced diet.
Additionally, young wheat leaves, kale, and green sprouts have become popular "superfoods" for their chlorophyll and micronutrient content.
Properties and benefits of chlorophyll
Chlorophyll, whether consumed naturally in vegetables or as chlorophyllin supplements, has been the subject of numerous studies. While scientific evidence is still limited in humans and some effects have only been observed in animals or in preliminary studies, numerous potential benefits have been attributed to it :
1. Powerful antioxidant action
Chlorophyll helps neutralize free radicals , which are responsible for premature aging and cell damage that can lead to chronic diseases. Its antioxidant effect contributes to:
- Reduce oxidative damage in cells and tissues
- Protect the skin against aging
- Reduce the risk of degenerative disorders
A diet rich in antioxidants like chlorophyll can help prevent diseases such as diabetes, Alzheimer's, and some types of cancer.
2. Potential anticancer effect
Some studies indicate that chlorophyll and chlorophyllin may help block the absorption of potential carcinogens , such as nitrosamines found in processed meats. Animal research has also shown that chlorophyll can:
- Reduce the incidence of liver and gastric tumors, depending on the dose
- Limit the absorption of aflatoxins, substances linked to liver cancer
- Provide a protective effect against genetic damage and oxidative stress
3. Promotes cleansing and detoxification of the body
Chlorophyll is known for its ability to eliminate toxins and heavy metals from the body . By facilitating detoxification and acting as a chelating agent, it contributes to:
- Support liver function and detoxification
- Stimulate the elimination of metabolic waste
- Contribute to general well-being and "internal cleansing"
Some experts indicate that chlorophyll increases the activity of enzymes involved in removing toxins from the blood, promoting liver health.
4. Supports intestinal and digestive health
Chlorophyll improves intestinal transit, acts as a prebiotic, and promotes beneficial gut bacteria . Its effects include:
- Reduction of inflammation of the digestive tract
- Promoting bowel regularity
- Relief from symptoms such as heaviness, flatulence and bad breath
- Contribution to a healthy intestinal microbiota
These properties make chlorophyll an ally in cases of slow digestion, constipation, or intestinal imbalances resulting from stress, poor diet, or prolonged medication use.
5. Deodorizing and purifying effect
One of the most traditional uses of chlorophyll has been as a natural internal and external deodorant . It is attributed with the ability to:
- Reduce body, fecal, and urinary odors
- Neutralize bad breath, especially when caused by digestive disorders
- Reduce the intensity of odors in geriatric patients or those with certain metabolic conditions
This is due to chlorophyll's ability to modify sulfur compounds and amines that cause unpleasant odors.
6. Contributes to the formation of red blood cells and oxygenation
The structural similarity between chlorophyll and hemoglobin has led to various studies on their potential effect on improving blood oxygenation. It has been observed that:
- Promotes the production of red blood cells, being useful as support in cases of mild anemia
- Improves oxygen supply to tissues
- Supports vitality, energy and physical endurance
This benefit is especially relevant for athletes, people with frequent fatigue, or low iron levels.
7. Anti-inflammatory and skin regenerating effect
Chlorophyll and its derivatives can reduce inflammation, accelerate healing, and improve skin texture and hydration . Studies have shown that its topical application:
- Promotes the healing of wounds and burns
- Reduces pore size and redness
- Helps maintain skin balance, especially in people with acne or skin sensitivity
Currently, it is found in creams, serums, and dermatological preparations to improve the health and appearance of the skin.
8. Promotes alkalization of the body
Regular consumption of chlorophyll can help balance the body's pH , creating a less acidic and more alkaline environment. A balanced pH has been associated with a reduced risk of chronic diseases and increased vitality.
9. Supports metabolism and appetite control
Some preliminary studies suggest that chlorophyll may help regulate appetite and control weight by:
- Increase the feeling of satiety
- Control blood glucose levels
- Reduce food anxiety spikes
This could translate into natural support for those seeking to maintain a balanced diet and a healthy weight.
How to consume chlorophyll: foods, juices, and supplements
The safest and most efficient way to benefit from chlorophyll is through a diet rich in fresh, leafy green vegetables , preferably eaten raw or cooked gently, such as steamed, to preserve their chlorophyll content.
For those who want to boost their intake, there are chlorophyll and chlorophyllin supplements in formats such as:
- Liquid (drops to dissolve in water or juices)
- Capsules or tablets
- Green smoothie powder
- Creams or ointments for topical application
The most common dose of chlorophyllin is usually between 100 and 300 mg per day for adults , divided into several doses. For liquid chlorophyll, recommendations typically suggest one tablespoon diluted in water once or twice a day . However, individual needs can vary, and it is advisable to consult a healthcare professional before starting any supplementation, especially if you are taking medication or have pre-existing medical conditions.
Precautions and possible side effects of chlorophyll
In general, chlorophyll consumed from natural sources does not pose health risks , except in rare cases of allergy to a specific plant. However, exceeding the recommended doses of chlorophyll or chlorophyllin supplements may lead to the following:
- Mild digestive disorders: nausea, diarrhea, stomach discomfort or flatulence
- Changes in the color of the tongue, teeth, urine, or stool (green or yellowish)
- Possible sensitivity to sunlight (photosensitivity) in sensitive individuals
- Allergic reactions or skin irritation (when applied topically)
- Interactions with medications, especially antibiotics, antifungals, antihistamines, cholesterol-lowering drugs, nonsteroidal anti-inflammatory drugs, and diuretics
