Green tea liver health -

Several food ingredients have long been known for their health benefits when used as a normal part of the diet and have been formulated into dietary supplements for that purpose.

Although traditional green tea as a beverage has a long history of consumption, the use of green tea extract GTE is relatively recent and has gained wide popularity as an ingredient in dietary supplements DS , especially in products promoting weight loss. The USP Dietary Supplements Expert Committee started investigating reports of liver injury associated with the consumption of green tea extract GTE in and published a review article in which they proposed the inclusion of a label caution statement based on evidence from 34 adverse event reports that were reviewed.

However, the proposal was abandoned as the evidence was considered inadequate. As is USP practice of continuously reviewing its standards and guidelines, the EC continued to monitor the literature for further cases of liver injury related to GTE and in , USP decided to re-introduce a cautionary labelling statement based on additional data that showed that GTE continued to be associated with liver injury.

Even then, the Expert Committee judged that the information reviewed was still insufficient to determine whether the reports of liver damage were due to GTE itself or external factors, such as contamination occurring during the manufacturing process.

At that point, USP convened a Green Tea Extract Hepatotoxicity Expert Panel, which was tasked with performing a comprehensive review of the literature on GTE-related hepatotoxicity to better understand the relationship between the reported toxicity to the liver and other factors such as chemistry, manufacturing, and controls CMC , intake of known compounds of GTE, and how the body processed these compounds pharmacokinetics and pharmacodynamics.

The results of the work from the Expert Panel were published in February in the journal Toxicology Reports. Authors of the manuscript are experts from industry, academia and regulatory agencies.

The manuscript concluded that GTE may contain solvent residues, pesticide residues, and other impurities that can cause liver damage in susceptible people.

But, of greatest significance, was research suggesting that a specific compound in green tea that is most abundant Epigallocatechin gallate or EGCG , can saturate the liver, increasing the potential to liver disease. Take with food. Do not use if you have a liver problem and discontinue use and consult a healthcare practitioner if you develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice yellowing of the skin or eyes.

Also, it lets consumers and distributors know that the dietary supplement was manufactured in accordance with a USP quality standard, offering greater assurances of quality manufacturing.

For those wondering whether brewed green tea has the same side effects as consuming GTE, both Oketch-Rabah and Muldoon-Jacobs respond that you can keep drinking your green tea.

The amount of EGCG and other components in brewed green tea is much less than the concentrated GTE and has not been associated with any adverse effects.

In the U. Green tea is packed full of this plant antioxidant. Citrus fruits stimulate the liver and help it turns toxic materials into substances that can be absorbed by water. Grapefruit is especially good as it contains naringin and naringenin, which are antioxidants that reduce inflammation to protect the liver from injury.

Grapefruit can, however, interact with some medications, so it's recommended you talk to your doctor if you have concerns. Garlic is full of sulphur, which activates liver enzymes that help your body flush out toxins. It also has a lot of selenium, a vital micronutrient that helps boost the natural antioxidant enzyme levels in our livers.

BBC Food: Can a vitamin pill a day keep the doctor away? As part of his mid-life health kick, Jim had started taking a green tea supplement because he had heard it might have cardiac benefits. These supplements have grown in popularity in recent years, often breathlessly promoted online for their antioxidant benefits, and their supposed ability to aid weight loss and prevent cancer.

He had been taking the green tea supplement for two to three months when he became ill. According to Jim's medical record this is the presumed cause of his liver injury. After his admission to hospital, Jim went into a "holding pattern", waiting for the results of a series of blood tests to establish the seriousness of his liver injury.

Then, about three weeks after his wife had first noticed he looked ill, one of his liver doctors delivered the news he had been fearing: "She said you need a liver transplant. This has to happen fast.

You have days - you don't have a week. It really crystallises what's important in life. I wasn't there thinking about projects at work. I was thinking of different people that were important to me for different reasons. What is it about green tea supplements that might cause harm at certain doses to some people?

Scientists do not know for certain. Because green tea has been drunk for thousands of years, supplements consisting of its concentrated form are regulated in the US and Europe as foods, not medicines. That means that specific safety testing has not been required, so the scientific picture of how green tea supplements might affect our health is incomplete.

Concern has focused on a potentially toxic ingredient called Epigallocatechingallate or EGCG, the most abundant of the naturally occurring compounds with antioxidant properties in green tea, called catechins. There are likely to be a number of factors that might make an individual susceptible to harm from EGCG including genetics, and the way supplements are used.

There may well be other factors of other drugs, other chemicals, use of alcohol that are also important as modifying factors. Antioxidants are a group of vitamins and other compounds that for many have taken on miraculous properties, helping to drive the global market for supplements of all kinds, now worth more than £bn per year.

Antioxidants ward off "free radicals", molecules produced in our cells as they turn oxygen and food into energy. Just as oxygen and water corrode iron, too many free radicals can damage our cells.

In the s, Prof Denham Harman theorised that free radicals drove the process by which the body ages and could lead to disease. But some scientists now believe that free radicals at certain levels may be beneficial for human health, and argue that the orthodox view of the last half century that antioxidants are an unalloyed good is outdated.

While millions of people take green tea supplements safely, at least 80 cases of liver injury linked to green tea supplements have been reported around the world, ranging from lassitude and jaundice to cases requiring liver transplants.

Those harmed after taking green tea pills have included teenagers, like year-old Madeline Papineau from Ontario, Canada who developed liver and kidney injury, and an year-old woman diagnosed with toxic acute hepatitis.

A recent investigation by the European Food Safety Authority into the safety of green tea concluded that catechins from green tea drinks are "generally safe", but when taken as supplements catechin doses at or above mg per day "may pose health concerns".

The EFSA could not identify a safe dose on the basis of available data and called for more research to be carried out. The day after Jim was told he needed a liver transplant, amazingly he was told a suitable liver had been found. The phone call that there was a match gave me hope that there would be something positive on the other side of this for me," he says.
