- Green tea is rich in useful plant connections, but sipping the tea is not completely risk -free.
- Many of the active connections in the green tea disturb some medication such as blood thinners and stimulants.
- You may want to restrict or avoid green tea if you are pregnant, have caffeine sensations or anemia.
Since around 3000 BC BC, people enjoy green tea for its many health benefits and their distinctive taste. In recent years, research has uncovered its supportive connections to weight loss, improved focus, anti-aging effects and cancer prevention. “Green tea is rich in antioxidants and with polyphenols, especially catechins (such as EGCG), which can help combat inflammation and reduce oxidative stress,” says Sheeri Jonnala, MS, RD. But they are the same bioactive substances in green tea that can cause dangerous interactions with several medications.
“While green tea is widely regarded as a healthy drink, there are certain circumstances under which its use may not be appropriate or should be addressed with caution,” says his use, “says his use,” says his use, “says his use,” says carefully, ” Jessica Beal, Pharm.D. Here are five medication that can interact with green tea.
1. Blood thinner
Anticoagulans drugs that dilute the blood by reducing the coagulation effect of vitamin K such as warfarin (also known as coumadine or jantoves) can be less effective when taking large amounts of green tea. One of the most important variables that you should take into account when taking warfarin is the amount of vitamin K, which you consume through food or nutritional supplements and maintain a consistent admission. “While the vitamin K content of green tea is much lower than that of leafy vegetables, a great or sudden increase in the absorption of green tea could reduce the effectiveness of warfarin, which leads to a risk of coagulation,” says Beal.
While it is unlikely that one or two cups of green tea will affect their INR values (the measure of how long their blood takes to grate), cases of reduced war effectiveness were reported by taking a gallons of green tea or more per day.
2. Stimulants
A cup of regular green tea contains about 30 milligrams of caffeine, a stimulant of the nervous system. It has less caffeine than what you find in a cup of coffee, but it can still add up and interact with other medication that has stimulating effects on the body, e.g.
“In combination with stimulating drugs, there can be an additive effect that leads to an increased heart rate, increased blood pressure, anxiety or insomnia,” explains Beal. If you take a stimulating drug, the choice of the decaffeinated green tea may be the best option.
3. Iron preparations
The anemia of iron deficiency is an important problem of public health that affects up to 18% of women and a lower percentage of men around the world. Anemia can lead to extreme tiredness, brittle nails, troubled legs and mood disorders and is often treated with iron preparations to increase the mirrors quickly and effectively.
Unfortunately, drinking green tea can not only affect the absorption of iron preparations, but also increase the risk that iron deficiency anemia is primarily developed. While research is limited and somewhat contradictory, some studies have found that connections, including phytics, calcium, tannins and specific polyphenols in the green tea, can limit the absorption of non-hem iron that is already poorly absorbed by the body.Present If iron deficiency is a problem, the separation of green tea from your iron preparations can help to eliminate absorption problems for an hour or two, Beal recommends.
4. Certain drugs for mental health
Green tea can increase the pharmaceutical level of antipsychotics such as clozapine (clozaril) or olanzapine (cypprexa) and the antidepressant amitriptylin (Elavil), explains Beal.PresentPresent“Caffeine in the green tea is metabolized by the liver enzyme CYP1A2, the same way that these medication uses,” adds Beal, that the caffeine competes for metabolism and the drug level and the risk of side effects such as sedation, significant changes in blood pressure or fits.
Who should avoid green tea?
Apart from medication, you will find some cases in which you want to avoid or limit the amount of green tea that you drink, or limit:
- You are pregnant or breastfeeding: While the limitation of caffeine is recommended to less than 200 to 300 milligrams per day during pregnancy and breastfeeding, green tea can also influence the availability of nutrients for a growing fetus. “Green tea can reduce the folat absorption, a nutrient that is of crucial importance to avoid neural tube defects,” says Jonnala.
- You have anemia: “Green tea contains tannins and catechins that bind non-hem iron and reduce absorption, which makes it more difficult to correct low iron levels,” says Beal.Present
- You are sensitive to caffeine: While green tea has much less caffeine than coffee or energy drinks, this can still cause your sleep, heart rate, fear of fear or your migraines if you are sensitive to its effects.
- You have hypotension: Green tea catechins have several activities that can reduce blood pressure, whereby a large review of randomized controlled studies can determine that green tea can play a role in reducing systolic and diastolic blood pressure in humans with or without high high pressure.
Our expert
Green tea is rich in antioxidants and powerful plant connections that offer many health benefits, but it is not completely risk -free. Many of the active connections in the green tea that offer advantages can affect certain drugs, including blood thinners, stimulants, iron preparations, blood pressure medication and some psychological medicines.
Drinking green tea could also harm more than benefits if they are pregnant, have caffeine sensations, have anemia or fight with low blood pressure. If you love green tea, but take a medication or have a state of health, it is best to inquire with your doctor and pharmacist to ensure that this is a secure option.
