Green tea has a high content of vitamins and minerals. It contains ascorbic acid (vitamin C) in amounts comparable to a lemon. Green tea also contains several B vitamins which are water soluble and quickly released into a cup of tea. Five cups of green tea a day will provide 5-10% of the daily requirement of riboflavin, niacin, folic acid, and pantothenic acid. The same five cups of green tea also provide approximately 5% of the daily requirement of magnesium, 25% of potassium, and 45% of the requirement for manganese. Green tea is also high in fluoride. A cup of green tea provides approximately 0.1 mg of fluoride, which is higher than in fluorinated water.

- It is vital to the production of collagen, which is involved in the building and health of cartilage, joints, skin, and blood vessels.
- It helps protect the fat-soluble vitamins A and E as well as fatty acids from oxidation.
- It aids in neutralizing pollutants.
- It is needed for antibody production.
- It has natural antihistamine properties.
