What is chlorophyll?
Chlorophyll is a natural pigment found in green plants, algae and some bacteria. Its chemical structure closely resembles that of haemoglobin in our blood, with one difference: the central atom in chlorophyll is magnesium, while in haemoglobin it is iron. This is why chlorophyll is sometimes called the "lifeblood of plants".
Benefits of chlorophyll
Plants use chlorophyll to produce energy. But it is also a nutritious substance for us humans. Green plant pigment turns out to be packed with vitamins and minerals. It is rich in vitamins A, C, E and K, as well as minerals such as magnesium, calcium, potassium and iron. A green source full of valuable nutrients!
How is chlorophyll extracted and processed?
Chlorophyll is extracted and processed into supplements in several ways. The most common method is extraction from alfalfa, wheatgrass or mulberry. The pigment is carefully isolated to preserve its natural properties.
Chlorophyll is available in various forms, such as:
- Liquid chlorophyll or chlorophyll drops: a popular choice because of their rapid absorption.
- Chlorophyll capsules or tablets: convenient for everyday use.
- Chlorophyll water: a ready-to-drink option for hydration and vitality.
Research suggests that liquid chlorophyll is absorbed by the body more quickly than chlorophyll in solid form, such as capsules. (source) This may be one reason why some people prefer liquid chlorophyll.
Where can you find chlorophyll in your everyday diet?
Want to get chlorophyll naturally? Choose green leafy vegetables and algae, such as:
- Spinach
- Kale
- Parsley
- Wheatgrass
- Spirulina and Chlorella
According to a scientific analysis, algae such as spirulina and Chlorella contain significantly higher concentrations of chlorophyll than leafy vegetables, making them an efficient source for those looking to increase their chlorophyll intake. (source) Some people prefer supplements, such as chlorophyll drops or liquid chlorophyll, because they contain a higher concentration and are more easily absorbed.
Does chlorophyll have any side effects?
Chlorophyll is generally considered safe when used normally. However, there are a few things to bear in mind:
- In some cases, chlorophyll may have a mild laxative effect.
- At high doses, urine or stools may take on a greenish colour.
- Some people experience mild stomach discomfort or nausea when taking supplements.
An animal study found that chlorophyll at higher doses may cause changes in digestion. (source) If in doubt, it is therefore advisable to consult a doctor or specialist, especially if you want to take chlorophyll alongside other supplements or medicines.
