Research shows that consuming green tea significantly lowers systolic and diastolic blood pressure, which are the two different numbers by which a person's blood pressure is recorded. Moreover, a very large long-term study published in followed two groups who had no history of heart disease.

The first group was made up of people who drank green tea more than three times a week, and the second group was made up of people who never drank green tea, or didn't drink it habitually. In a follow up about seven years after the start of the study, scientists found that those who drank tea regularly were likely to have 1.

Catechin is a major component of green tea. Catechins are natural antioxidants that have antioxidative, anti-inflammatory, and anti-hypertensive effects. They lower cholesterol levels by decreasing the absorption of cholesterol into the body.

An analysis of 14 studies showed that drinking an average of two cups of green tea per day for 10 years resulted in significant reductions in LDL cholesterol levels. LDL cholesterol is also known as bad cholesterol, because it can cause plaque buildup in your arteries, which increases your risk of getting a heart attack or a stroke.

The mechanism for this isn't well-defined, though one theory is that epigallocatechin gallate ECGC , a compound of green tea, affects the circulation of bile acids, which helps to regulate cholesterol," says Ring.

Green tea also helps to keep your bones healthy and strong. Research shows that it may help treat and prevent osteoporosis, a condition that makes your bones weaker and more prone to fractures. Flavonoids are and phytoestrogens are plant chemicals that can strengthen bone formation and prevent the breakdown of bone tissue.

In a study , postmenopausal women with weak bones and low bone mass were put into four groups. The results of the study showed that the group of women who were given compounds derived from green tea experienced a notable improvement in their bone health.

A study also concluded that green tea may benefit bone health, after examining bone-forming cells. The researchers exposed the cells to epigallocatechin EGC , gallocatechin GC , and gallocatechin gallate GCG , which are all main components of green tea.

They also observed that high concentrations of EGC disrupted the activity of osteoclast, a cell that weakens bones. Green tea contains a micronutrient called epigallocatechin gallate EGCG that may be responsible for green tea's skin repair properties.

Some research shows that EGCG contains antioxidants , which help to prevent sun damage. It also boosts skin hydration, moisture retention, and prevents wrinkle formation.

Green tea has also been shown to have anti-aging properties. A small study studied the effects of using oral supplements and applying green tea topically on aging skin for 8 weeks. Researchers found that the combination of using green tea topically and orally in the participants caused an improvement in the skin's elasticity.

Catechin, a polyphenol in green tea, also helps to soothe inflamed skin when used topically. Green tea comes in different forms, but to enjoy the optimal benefits of tea, it's best to drink it plain.

Some research suggests that adding milk may counteract some of the health benefits of drinking tea. It's important to note that green tea contains caffeine, so if you have a caffeine sensitivity, you might want to consume it in smaller amounts. Close icon Two crossed lines that form an 'X'.

Rhodiola is one of the best studied and most potent adaptogens. Rhodiola is fast-acting and has been shown to fight fatigue, support a positive mood, and improve physical and mental performance.

It also helps increase the availability of energy during the day and promote restful sleep. Panax ginseng, also known as Asian ginseng, is a potent adaptogen. Ginseng contains naturally occurring ginsenosides, which play a role in improving focus, sharpening memory and supporting overall well-being.

Ginseng promotes the release of nitric oxide, which opens blood vessels and improves blood flow to the brain and muscles. Choline is essential in the formation of acetylcholine, a neurotransmitter that plays an important role in mental function. Choline enhances focus, supports healthy memory, and promotes calm.

Research has linked high blood pressure with a higher risk of several health problems, including heart attack and stroke. L-theanine may help reduce stress, and a reduction in stress and increased relaxation can lower the heart rate. In turn, this may help lower blood pressure. Some research on animals suggests that L-theanine may increase the effectiveness of a chemotherapy drug called doxorubicin.

It is possible that it makes doxorubicin more effective by increasing the amount of the drug in cancer cells. However, scientists need to do more research to understand the specific interactions between these chemicals.

Scientists have not yet conducted high-quality research in humans. Many studies to date have had a small sample size, meaning that very few people took part in the research. Data from just a small number of people are less likely to be conclusive than those from larger groups.

Other studies have used animals, such as rats or mice. However, humans are likely to react differently to animals, so these results may not be applicable. A person should speak to their doctor before taking supplements.

Most people are unlikely to experience side effects when they take L-theanine, but the supplement may interact with some medications. It is essential to speak to a doctor about any current medications before taking L-theanine supplements. L-theanine is not a medication, so there are no official guidelines regarding how much a person should take.

However, the supplement is unlikely to cause an overdose. L-theanine is usually available in the form of mg tablets. A person can consult a doctor before taking these supplements to get their advice on dosage.

Experts consider L-theanine to be generally safe for people to take as a supplement, but more research is necessary to confirm its possible health benefits. Small studies and research on animals suggest that L-theanine could help with relaxation, improved sleep quality, and neuroprotection.

Green tea's benefits may include: Increased Mental Alertness A review published in Current Pharmaceutical Design found that caffeine, particularly the amount in matcha, improved alertness, arousal, and vigor during long, demanding cognitive tasks.

A Japanese study found that people who consumed five or more cups of green tea each day had a 26 percent lower risk of dying of cardiovascular disease during a seven-year period compared with people who drank only a cup per day.

A article published in December in the European Journal of Preventive Cardiology surveyed health data from , participants and found that those who frequently drank tea were 20 percent less likely to suffer from heart disease or stroke — and green tea had the strongest impact.

Lower Cholesterol A systematic review and meta-analysis published in in Nutrition Journal concluded that green tea consumption lowers levels of LDL "bad" cholesterol in people of all body weights. Cancer Prevention Some researchers suspect that catechins have the ability to block cancer-causing free radicals.

Reduced Risk of Diabetes In a study of a half million Chinese adults published in July in The American Journal of Clinical Nutrition , daily green tea consumption was associated with a lower risk of type 2 diabetes and a lower risk of all causes of mortality in patients with diabetes.
