Green tea liver health -

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. and around the world, quality standards developed by the U. As for supplements , you should always play it on the safe side, as even natural ingredients can carry some serious side effects.

Child Development. It is also said to help in the promotion of oral health and other physiological functions such as body weight control, better bone mineral density and more. There has been an increasing interest in its health benefits , so naturally, that has led to the inclusion of green tea in the group of beverages that have functional properties.

However, too much of anything can be problematic. If one consumes green tea extract , it might provide some protection against obesity, cancer, cardiovascular disease and type 2 diabetes. However, too much of this beverage is not good for your liver, according to research from Rutgers, published in The Journal of Dietary Supplements.

Senior author Hamed Samavat of the study, said that learning to predict who will suffer liver damage is potentially important.

They probed whether people with certain genetic variations were more likely than others to show signs of liver stress after a year of consuming milligrams of the predominant antioxidant in green tea every day.

The antioxidant is a catechin known as epigallocatechin gallate EGCG. Laura Acosta, then a doctoral student, now a graduate, led the researchers, and they selected two genetic variations in question. They did so as each variation controls the synthesis of an enzyme that breaks down the EGCG.

On average, the women with the high-risk UGT1A4 genotype saw the enzyme that indicates liver stress shoot up nearly 80 percent after consuming the green tea supplement for nine months. Participants with low-risk genotypes saw the same enzyme increase by as much as 30 percent.

He added that the full explanation probably includes several different genetic variations and various non-genetic factors.

In lateTeq Canada issued an Lifestyle habits and bone health fea about potential liver toxicity from green Enhance your endurance capacity extract. The warning ta anyone lkver green tea extracts, particularly those with liver disease, to watch for any signs of liver damage. It also urges children to avoid using products containing green tea extract. Green tea extract is available in many forms, including capsules, tablets, powders, and liquids. Even among similar formulations, green tea extract often contains varied amounts of active constituents.
