Chlorophyll and matcha: why green powder is so rich in chlorophyll

Matcha is one of the most concentrated food sources of chlorophyll. This molecule, responsible for its intense green color, is not just aesthetic: it directly reflects the quality of matcha and contributes to several of its benefits. Here's how shading tea plants explains this richness, what chlorophyll provides, and why truly green matcha is so much better than pale or khaki matcha. What is chlorophyll Chlorophyll is the natural pigment that allows plants to capture sunlight and convert it into energy via photosynthesis. This molecule gives leaves their green color. Its chemical structure is very close to that of human hemoglobin, with one detail: the center of the molecule contains magnesium in chlorophyll and iron in hemoglobin. This resemblance has fueled extensive scientific literature on the potential effects of ingested chlorophyll on the body. All green plants contain chlorophyll. But few concentrate as much as quality matcha. A 2g serving of matcha provides approximately as much chlorophyll as a 100g serving of raw spinach. This density changes the game nutritionally. Why matcha is so rich in chlorophyll The secret lies in shading. Three weeks before harvest, tea plants intended for matcha are covered with tarps that reduce sunlight by 70 to 90%. This technique, which has existed since the 16th century in Japan, is one of the foundations of matcha cultivation. Deprived of light, the plant reacts to survive. To maximize its ability to capture the little light that filters through, it produces much more chlorophyll. The concentration can double, or even triple, compared to a tea plant grown in full sun. In parallel, shading also increases the concentration of L-theanine and reduces the bitterness associated with catechins. These three combined effects (more chlorophyll, more L-theanine, less bitterness) are what distinguishes ceremonial matcha from a classic green tea. This precise agricultural dimension is detailed in the matcha plant factsheet, which covers cultivars and cultivation methods. Why good matcha is intensely green The color of matcha is probably the most immediate and visible quality marker. Here's what it says about the product. A very intense, almost fluorescent green, indicates ceremonial or premium grade matcha, long-shaded, from the first leaves of the first harvest (shincha or ichibancha), delicately ground with a stone mill. A duller, almost olive green, indicates culinary grade matcha, or less shaded leaves, or a late harvest (nibancha, sanbancha). It is less concentrated in chlorophyll and L-theanine. A green that tends towards khaki or yellow is a warning sign: old (oxidized) matcha, poor quality matcha, or matcha that isn't really matcha (a blend of ground green teas). To be avoided. Color is therefore not just a matter of aesthetics: it directly reflects the richness of bioactive compounds. Benefits associated with chlorophyll Research on ingested chlorophyll is still developing, but several avenues are documented. Antioxidant power Chlorophyll has a measurable antioxidant capacity, complementary to that of the catechins already present in matcha. This synergy partially explains matcha's position in the rankings of the most antioxidant foods. Detoxification support Several studies have shown that chlorophyll can bind to certain toxic compounds (aflatoxins, heavy metals) in the digestive tract, limiting their absorption. This "chelating" effect is one reason why chlorophyll is being studied as support for natural detoxification processes. Benefits for breath and digestion Chlorophyll has been used for decades as an internal deodorant. Its gentle antibacterial properties help reduce bad breath of digestive origin and balance the intestinal flora. Effects on the skin Topical studies (application to the skin) have documented improved healing and reduced skin inflammation with chlorophyll. Internally, the effects are less direct but consistent with a general anti-inflammatory action. These effects are part of the broader context of the benefits of matcha, where chlorophyll plays a role among other active compounds. Chlorophyll, matcha quality, and organic certification Organic certification provides a guarantee of the absence of pesticides and chemical fertilizers, which is important for a product consumed entirely like matcha. But it says nothing about shading, cultivar, or grade. Organic matcha can be pale, dull, and weakly concentrated in chlorophyll. The comparison between organic and conventional matcha must therefore be assessed by crossing several criteria. The best compromise remains matcha that is both organic, Japanese, long-shaded, and from a suitable cultivar. This combination guarantees an optimal concentration of chlorophyll, L-theanine, and catechins. Frequently asked questions about chlorophyll and matcha Does drinking matcha equate to taking a chlorophyll supplement? A cup of quality matcha provides a significant amount of chlorophyll in a natural context rich in cofactors (L-theanine, catechins, vitamins). Isolated chlorophyll supplements provide a higher dose but without this synergy. Matcha remains a more complete approach. Why is my matcha less green than before? Several possible causes: oxidation due to time (matcha ages within 4 to 6 weeks after opening), poor storage (light, air, humidity), or late harvest of the current production. Storing matcha in an airtight container away from light significantly prolongs its vibrancy. Does chlorophyll store well in matcha? It is sensitive to light and oxygen. Well-stored matcha retains a vibrant color for several weeks after opening. Poorly stored matcha loses its color in a few days, which is immediately visible to the eye. What is the difference between chlorophyll in matcha and in spinach? Chemically, it's the same molecule. But the matrix is different: matcha chlorophyll is ingested with L-theanine, catechins, and caffeine, in a context of fine, immediately bioavailable powder. That of spinach is encapsulated in vegetable fiber, which slows its absorption. Should I choose the greenest matcha for chlorophyll? The more intense and fresh the green, the higher the chlorophyll concentration. This is one of the most reliable visual indicators for assessing the quality of matcha when purchasing. To fully enjoy the chlorophyll of vibrant, fresh-colored matcha, the TSUKI premium matcha collection offers shaded matchas from Shizuoka and Kagoshima, ground with a stone mill.
