Tea does contain vitamins, but in small amounts that won’t make a major dent in your daily requirements. A cup of brewed green or black tea provides trace levels of B vitamins, a modest amount of vitamin C (especially in matcha), and negligible vitamin K. Herbal teas like rosehip offer a bit more vitamin C, though still far less than eating a piece of fruit. The real nutritional story of tea is its antioxidants, not its vitamins.
Vitamin C in Green Tea and Matcha
Among true teas (all made from the same plant, Camellia sinensis), matcha delivers the most vitamin C because you consume the whole powdered leaf rather than steeping and discarding it. Lab analysis published in the journal Foods found matcha infusions contain roughly 32 to 45 mg of vitamin C per liter. A typical matcha serving uses about 240 mL (one cup) of water, which works out to around 8 to 11 mg of vitamin C per cup. That’s roughly 10% of the daily recommended intake for adults.
Regular brewed green tea contains less, since the leaves are removed after steeping and most vitamin C stays behind in the leaf. Black tea has even less because the oxidation process used during manufacturing breaks down vitamin C before brewing even begins. For comparison, a medium orange provides about 70 mg of vitamin C, so tea is not a practical way to meet your daily needs for this nutrient.
B Vitamins: Present but Minimal
Tea leaves contain riboflavin (vitamin B2) in detectable amounts. Research using sensitive laboratory methods found riboflavin concentrations ranging from about 0.6 to 3.3 micrograms per gram in black tea samples and up to 3.3 micrograms per gram in green tea. In practical terms, a single cup of brewed tea contributes only a tiny fraction of the 1.1 to 1.3 mg of riboflavin adults need daily. You’d need to drink hundreds of cups to approach a meaningful dose.
Other B vitamins like folate and niacin are present in tea leaves at similarly trace levels. They’re worth knowing about if you’re curious, but not worth counting toward your daily intake.
Vitamin K Is Nearly Absent in Brewed Tea
This matters most for people taking blood-thinning medications, who are often told to keep their vitamin K intake consistent. The good news: brewed black and green tea contain less than 1 microgram of vitamin K per cup. That’s essentially zero compared to a serving of broccoli (about 220 mcg) or spinach (about 145 mcg). Drinking tea will not meaningfully interfere with anticoagulant therapy, though matcha powder, since it includes the whole leaf, contains slightly more.
Herbal Teas Offer a Different Profile
Herbal “teas” aren’t technically tea at all. They’re infusions of other plants, and some contain more vitamins than Camellia sinensis. Rosehip tea is the most notable example, as rosehips are naturally rich in vitamin C. However, brewing destroys a significant portion of that vitamin C, so an 8-ounce cup of unfortified rosehip tea delivers only about 7.5 mg. That’s comparable to matcha and well below what you’d get from citrus fruit or bell peppers.
Hibiscus tea is often marketed alongside rosehip for its vitamin content, but its vitamin C levels are similarly modest once brewed. If you’re choosing tea specifically for vitamins, these herbal options edge out black tea, but none of them replace whole fruits and vegetables.
How Brewing Affects What’s in Your Cup
Water temperature and steeping time change the nutritional content of your tea in competing ways. Hotter water pulls more compounds out of the leaf, so you get higher concentrations of antioxidants and whatever vitamins are present. Research published in Molecules found that extraction efficiency increased steadily up to 100°C. But vitamin C is heat-sensitive, and the matcha data illustrates this clearly: infusions prepared at 25°C retained up to 44.8 mg/L of vitamin C, while those brewed at 80 to 90°C dropped to around 32 to 36 mg/L.
Steeping time follows a similar curve. Antioxidant concentrations rise for up to about two hours of extraction, then decline as compounds begin to break down. For a normal cup of tea steeped three to five minutes, you’re getting a fraction of what’s maximally available, but you’re also not degrading much. The practical takeaway: brewing at lower temperatures preserves more vitamin C, while hotter water extracts more antioxidants. Neither approach turns tea into a significant vitamin source.
Where Tea’s Real Nutritional Value Lies
Tea’s health reputation comes from its polyphenols, not its vitamins. These are plant compounds that act as antioxidants, and tea delivers them in concentrations far more significant than any vitamin it contains. Green tea is particularly rich in catechins, a family of polyphenols that have been studied for their effects on cardiovascular health, inflammation, and metabolic function.
Your body absorbs these compounds with varying efficiency. Smaller catechins are absorbed relatively well, while the larger ones (including the most abundant one in green tea) have lower bioavailability. Eating food at the same time as drinking tea can further reduce absorption, while regular daily tea consumption may improve it over time. Tea also provides fluoride, with black tea being a particularly concentrated source. One cup of brewed black tea can contain roughly 1 to 3 mg of fluoride depending on the brand and leaf age, which is relevant for dental health but also worth monitoring if you drink several cups daily.
So while tea does technically contain vitamins, thinking of it as a vitamin source misses the point. It’s a low-calorie beverage with meaningful antioxidant content and trace micronutrients. The vitamins are a bonus, not the headline.
