Liver injury effects of green tea—based products have been reported in sporadic case reports. 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.

Green tea extract GTE ECGG popular in weight loss, and epigallocatechin gallate EGCG bealth considered as the main active component. However, GTE is the anv cause of herbal and dietary supplement-induced liver healtj in the United Gealth.

Whether there is a greater abd of liver injury healht EGCG is consumed during dieting for weight loss has not been previously reported. Intriguingly, healhh found that EGCG caused dose-dependent hepatotoxicity on mice under dietary helath, suggesting lkver potential combination effects of dietary restriction and EGCG.

This original discovery suggests that people should bealth go on a anv while liger EGCG for weight loss; otherwise the risk of liver injury Nutrient timing for muscle maintenance be gealth increased.

Green tea is a beverage that has been brewed for thousands of years and has been widely popular across the world for hundreds of years. It is rich Lifer catechin compounds with antioxidant Flavonoids and hormonal balance, and healtu gallate EGCG is the most important component of green tea extract Healh.

It is popularly believed to have a Green tea extract weight loss pills range of wnd benefits, including ahd cancer, lowering cholesterol, reducing lifer, and delaying healfh Li et abd.

However, EGGCG contrast to these health wnd, Energy-enhancing superfood supplement number of drug-induced liver injury DILI cases when Heealth is used lliver weight loss has consistently increased, with GTE being the leading livet of HDS-DILI heakth the United Heapth Navarro et al.

The mice were adaptively fed livee 7 days, during which their EGCCG intake was monitored to obtain the average daily healhh intake per cage. The four administration groups were treated with intragastric EGCG Artichoke soup recipes the corresponding dose at the liiver time.

The control group and anr dieting group were given equal volume of normal saline through intragastric means. There were eight mice in each group. The frozen plasma was returned to room temperature, and alanine aminotransferase ALT and aspartate aminotransferase ASTglutathione S-transferase GST activity, and total bile acid TBA concentration were measured and calculated according to the kit instructions.

ALT kit No. The liver tissues of mice were collected, and routine histological sections were stained with hematoxylin and eosin HE.

Then, the pathological sections were photographed under a microscope. Terminal deoxynucleotidyl transferase dUTP nick end labeling TUNEL was used to detect and analyze the apoptosis of hepatocytes.

Image-Pro Plus 6. It was then centrifuged at 14, rpm for 15 min in a precooled 4°C centrifuge; μl of supernatant was pipetted and dried with nitrogen. Meanwhile, 10 μl of each sample was taken and mixed evenly and used as the quality control QC sample. For plasma metabolite chromatographic separation conditions and non-targeted metabolomics mass spectrometry detection conditions, please see the Supplementary Material.

Using MassHunter Qualitative Analysis software version B MZmine software version 2. The criteria for differences between groups were as follows: FC was greater than 1. At the same time, the obtained data matrix was imported into SIMCA-P software version Pathway analysis based on the identified metabolites was conducted using MetaboAnalyst according to the Kyoto Encyclopedia of Genes and Genomes KEGG pathway database www.

The experimental data was expressed as mean ± SD. We screened and identified differential metabolites to study the metabolic changes caused by EGCG and diet on the mice. EGCG and diet coregulated metabolites as shown in the Venn diagram in Figure 1A.

The pathways altered by EGCG and dieting mainly focused on fatty acid biosynthesis and pentose phosphate pathway Figure 1B. Biomarkers included gluconic acid, oleic acid, heptanoic acid, E -2, 6-dimethyl-2, 5-heptadienoic acid, vitamin D2 3-glucuronide, and 3-oxo-tetradecanoic acid.

The corresponding abundance changes were shown in Figure 1Cand the specific identification information was shown in Supplementary Table S1. We found that dietary restriction could slow down fatty acid synthesis, which could explain the fat loss effect caused by dieting.

EGCG could also slow down fatty acid synthesis, which was consistent with its claimed weight loss effect. Therefore, we compared the liver injury induced by EGCG with that induced by EGCG under dietary restriction in vitro and in vivo.

Figure 1. EGCG simulates the effect of dieting on fat loss. A The differential metabolites amount between dieting and control is displayed as pink, while that between EGCG and control is displayed as purple. The Venn diagram shows the shared metabolites between EGCG and dieting.

B Pathway enrichment of 38 common metabolites. C Relative abundance of fat loss biomarkers. Figure 2. Dieting exacerbates EGCG hepatotoxicity in mice. A Plasma ALT; AST; GST; TBA.

The data were expressed as mean ± SD. B Histological assessment of mice liver HE staining × magnification. C Hepatocyte apoptosis determination in mice liver using TUNEL assay × magnification.

The results of HE staining Figure 2B showed that the hepatocytes in the control, EGCG, and dieting groups represented with normal morphology. By contrast, obvious histological changes occurred in the diet combined with EGCG treatment group, including a decrease in the number of hepatocytes and some vacuolar degeneration, accompanied by infiltration of inflammatory cells.

In the TUNEL staining results Figure 2Cthere were basically no green fluorescence positive cells in the visual field of the single administration group compared with the control group, and there was no statistical difference in the calculated apoptosis rate. The above results indicate that EGCG can cause increased hepatocyte apoptosis under dietary restriction.

PCA and OPLS-DA analysis were carried out on the data in positive and negative ion modes using SIMCA-P. Figures 3A,B displayed the scattered point plots of PCA of all samples in positive ion and negative ion modes.

It could be seen that QC samples were concentrated in the middle of the score matrix projection plot, which indicated that the instrument remained stable during the analysis process. Figure 3. Metabolomic analysis of mice plasma. A The principal component analysis PCA score plot in positive ESI model.

B The PCA score plot in negative ESI model. In order to further obtain the differences between groups and different compounds, OPLS-DA modeling and analysis were carried out. We found that some important pathways were alteration, including linoleic acid metabolism, glycerophospholipid metabolism, sphingolipid metabolism, taurine, and hypotaurine metabolism Supplementary Figure S3.

Its downstream metabolites including 9 10 -EpOME, 9,DHOME, 12 13 -EpOME, 12,DHOME showed different degrees of upregulation in the combined treatment group Figure 4D. The above specific identification information is shown in Supplementary Tables S2, S3.

We identified 12 groups of LPC to PC transformations Figure 5B and eight phospholipid metabolites with no corresponding relationship. The specific identification information was shown in Supplementary Table S4. We could see that the length of the carbon chain affected by liver injury ranged from 14 to 22, including both saturated and unsaturated chains, indicating that this metabolic change did not have anything to do with the length of fatty acid side chain and the number of double bonds, but was only related to the formation of PC corresponding to the addition of a fatty acid side chain on LPC.

It could be seen that the changes in phospholipid component were extensive and not specific to a specific phospholipid component. Figure 5. PC is synthesized by LPC on the same line.

The values are based on Log2FCs of biomarkers relative peak intensity compared to the control. PC, phosphatidylcholine; LPC, lysophosphatidylcholine. The specific identification information is shown in Supplementary Table S5. These results showed that the metabolic transition from SM to CM was one of the important characteristics of dieting exacerbating liver injury induced by EGCG.

Download as PDF. Read More. Recent Popular. With growing concerns about the availability of medical appointments and medicines in these days of COVID, people are relying more and more on dietary supplements to support their health. According to IRI — a market research firm that tracks U. Dietary supplements are vitamins, minerals, amino acids, herbs or other botanicals taken to increase the total dietary intake of specific dietary ingredients. Dietary supplements are regulated by FDA as foods but are often taken by consumers to help support overall health, or sometimes to address specific health conditions. 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.

Specifically, if you're ingesting a lot of the highly concentrated form which can be found in weight-loss teas or on its own as a supplementary green tea extract liver damage can occur as a result. It's called hepatotoxicityand it happens when too many herbs or supplements — everything from ibuprofen to green tea extract — chemically induce liver damage. This particular type, herbal hepatotoxicity, can happen when you take too much of an herbal supplement or even down too many cups of highly concentrated herbal drinks a day.
