Brain-alerting effects are due in part to the presence in green tea of caffeine, which is a stimulant proven to enhance attention and alertness. (TrustedSource)

Green tea also contains L-theanine, an amino acid that has calming effects.

Combining L-theanine and caffeine promote brain function and mood — without the aftereffects commonly associated with caffeine.

• The green tea’s caffeine will cause insomnia, anxiety, irritability, nausea, or stomach upset if consumed in excessive amounts.

2. Iron Deficiency or Anemia and Bleeding Disorders

• Excessive consumption of tea can cause iron deficiency as tea contains a lot of tannins, which can combine with iron and inhibit its absorption in the gut.
• Many people enjoy a warm cup of tea after meals to help digest their food. Green tea can have the opposite effect if taken immediately following an iron-containing meal, though.  Therefore, you should take green tea at least 1 hour post meals.
• In exceptional instances, green tea may result in bleeding disorders. Green tea’s compounds lower fibrinogen levels, an integral blood clotting protein. Fatty acid oxidation is also inhibited by green tea, causing the blood to thin.

3. Pregnant and Nursing Women

Drinking more than two cups a day, however, can enhance the risk of miscarriage and other adverse effects. Moreover, overconsumption by pregnant women can enhance the risk of birth defects in newborns.
• Caffeine is able to pass through breast milk and impact the baby. Excessive consumption of caffeine during breast-feeding may produce sleep disturbances, irritability, and elevated bowel movement in breastfed infants. If you are breast-feeding, it is advisable that you consume no more than 200mg daily or best to consult your healthcare professional.

4. Issues related to Heart, Liver, High Blood Pressure, Diabetes

• Supplements of green tea extract have been associated with a few instances of liver injury. The extracts make liver disease worse if high doses are taken. In advanced liver disease, caffeine accumulates in the blood and is metabolized more slowly, taxing the liver.

5. Individuals who have Irritable Bowel Syndrome (IBS) or Diarrhea

• The caffeine from green tea, particularly when consumed in large quantities, is known to exacerbate diarrhea and IBS symptoms.
• The caffeine is a laxative since it activates the colon to contract more often. This produces more frequent bowel movements and can upset the stomach.

Individuals with stomach problems, iron deficiency anemia, pregnancy, liver or heart conditions, hypertension, or IBS are advised to moderate green tea consumption. Excessive caffeine or tannin may exacerbate conditions or affect drugs—moderate and timing is essential.
