Has anyone else had issues with muscle cramping due to use of green tea extract? If so do you have any sugestions on how to combat the cramping?

Thanks

don't use the extract there have been case reports of hepatotoxicity............just get a high quality green tea for brewing and drink 5-10 cups per day.

The doc has never said anything about it when I've tested values. I've been taking GT for many many years.

A review of the health effects of green tea catechins in in vivo animal models.Crespy V, Williamson G.
Nestlé Research Center, Vers Chez Les Blanc, CH-1000 Lausanne 26, Switzerland.

There is good evidence from in vitro studies that green tea catechins have a role in protection against degenerative diseases. However, the concentrations used in vitro are often higher than those found in animal or human plasma, and so in vivo evidence is required to demonstrate any protective effect of catechins. This article summarizes the most interesting in vivo animal studies on the protective effects of green tea catechins against biomarkers for cancer, cardiovascular disease, and other degenerative diseases. Generally, most studies using animal models show that consumption of green tea (catechins) provides some protection, although most studies have not examined dose response. Tea catechins could act as antitumorigenic agents and as immune modulators in immunodysfunction caused by transplanted tumors or by carcinogen treatment. Green tea has antiproliferative activity in hepatoma cells and hypolipidemic activity in hepatoma-treated rats, and some studies report that it prevents hepatoxicity. It could act as a preventive agent against mammary cancer postinitiation. Nevertheless, the implications of green tea catechins in preventing metastasis have not been clearly established. Long-term feeding of tea catechins could be beneficial for the suppression of high-fat diet-induced obesity by modulating lipid metabolism, could have a beneficial effect against lipid and glucose metabolism disorders implicated in type 2 diabetes, and could also reduce the risk of coronary disease. Further investigations on mechanisms, the nature of the active compounds, and appropriate dose levels are needed.

I personally consume 10+ cups of high quality tea per day and the effects on fat loss are very pronounced with weight training and cardio. What concerns me is some of the extracts may have questionable ingredients in them which may be linked to hepatotoxicity. I guess if you want to take an extract be careful what you buy.

Acute hepatitis after treatment for hair loss with oral green tea extracts (Camellia Sinensis).Verhelst X, Burvenich P, Van Sassenbroeck D, Gabriel C, Lootens M, Baert D.
Department of Gastroenterology, AZ Maria Middelares, Ghent, Belgium. [email protected]

Nutritional additives based on green tea have been claiming various beneficial health effects. However, several case reports on hepatotoxicity after the intake of green tea derivatives containing Camellia Sinensis have been published. We report a patient with an acute hepatitis after intake of an oral green tea derivative claiming protection against hair loss, showing a histological image compatible with drug induced hepatitis. Other important causes of hepatitis were excluded. After cessation of this nutritional additive there was a rapid and sustained recovery. We raise concern about the safety of nutritional additives with few proven beneficial effects and want to emphasize the importance of accurate and thorough history taking, with attention for over the counter drugs and herbal products.

Just read a report which pretty much outlines the same things that jboldman points out; but it does cyclists in more detail

` Scientists at the University of Birmingham in the UK studied the effects of GTE supplementation (containing 366mgs of GTE per day )in 12 healthy men who performed 30 minutes of cycling exercise @ 60% of VO2max before and then again 24 hours after GTE supplementation. The results were dramatic compared to a group who took a placebo; Those taking GTE increased their fat burning rates by average of 17%`.
What stands out in the report is the contribution of fat oxidation to total energy expenditure having taken a GTE supplement was also raised by about 17%. This would obviously leave an athlete with more muscle stored glycogen for the intense efforts.

Erm, sorry to be blunt, but is green tea supposed to have some sort of a flavour? Or did I buy the wrong sort (different country so unlikely to have the same brands here. I just bought the most expensive brand . . . .)

green tea should have that nice green flavor. Usually the flavor is very mild, don't expect it to brew up like coffee.

Perhaps I'll try a different brand, or maybe try leave 2 tea bags infusing, because it was really bland
More like a cup of green coloured hot water

In the mean time, will keep on with it with maybe 1tspn of brown sugar.
