Tea contains multiple vitamins, with vitamin C being the most abundant, along with vitamin A precursors, vitamins B1, B2, P, PP, K, and folic acid. Therefore, drinking tea in moderation can help supplement the body's need for various vitamins.

Vitamin C: Nutritionists suggest that the human body requires the most vitamin C daily, approximately 75-150 mg. Since the body cannot store large amounts of vitamin C, it must be obtained from food.

Tea is rich in vitamin C, especially green tea, which contains far more vitamin C than most vegetables. Every 100 grams of green tea contains about 180 mg of vitamin C, while high-quality green tea can reach up to 500 mg. Generally, a standard tea infusion contains 2-4 mg of vitamin C per 100 milliliters.

Vitamin A: The content of vitamin A precursors (carotenoids) in tea is also higher than in most vegetables. Carotenoids have the physiological effects of vitamin A, with about 5.46 mg per 100 grams of tea.

Vitamin B1: Vitamin B1 helps prevent and treat polyneuritis. Every 100 grams of tea contains 0.07 mg, which is seven times the amount found in apples.

Vitamin B2: Vitamin B2 is essential for maintaining normal retinal function. Every 100 grams of tea contains up to 1.20 mg, about five times more than soybeans, 20 times more than rice, and 60 times more than fruits.

Vitamin P: Tea also contains vitamin P, which is related to microvascular activity. A deficiency in vitamin PP (niacin) can lead to pellagra, diarrhea, and dementia. The vitamin PP content in tea far exceeds that in vegetables and fruits, with 4.7 mg per 100 grams of tea, compared to 0.3 mg in cabbage and 0.2 mg in watermelon.

Folic Acid: Folic acid is a crucial member of the B-vitamin family and plays a vital role in preventing anemia, yet it is often lacking in common foods. Studies show that drinking five cups of green tea daily can provide a quarter of the body's daily folic acid requirement.

Tea contains various vitamins, with an absorption rate of about 80% under normal brewing conditions. Therefore, moderate tea consumption can significantly contribute to meeting the body's vitamin needs.
