Too Much Green Tea Extract

How Much Green Tea Extract Per Day For Weight Loss?

Even though green tea and its extract seem to pose no harm to humans, some people did report side effects. Exceeding the recommended daily intake of green tea extract can be a bad idea for several good reasons.

For example, a study examined the consequences of high-dosing green tea catechins , and the participants reported several negative side effects:

Is It Safe To Take Green Tea Extracts Every Day

Taking green tea extracts is not the same as drinking cups of green tea. Although both have similar roots, their production process, active ingredient contents and effects on your body may vary.

In drinking green tea, you must drink around eight cups every day, as this is considered a moderate and safest amount to consume. Consuming more than eight cups of green tea may cause several negative side effects, such as mild to moderate headaches and irregular heartbeat. Over time, drinking excessive amounts of green tea may lead to liver injury.

On the other hand, green tea extracts can be consumed in different forms, such as in capsules, liquid or powder. It is safe to take about 250 to 500 mg on a daily basis. This is suggested to be taken with food in your stomach. Taking more than this recommended amount may be toxic for you.

Green Tea And Weight Loss: What The Research Says

In a double-blind cross over study, investigators found that 300mg of green tea extract, combined with 150mg of caffeine significantly increased fat oxidation rates at rest, and were 20% higher than the placebo of caffeine alone .

During exercise fat oxidation rates increase 10-fold, due to the energy demand of energy that your muscles require . In a study published in the Journal Of Clinical Nutrition two studies were performed to determine if green tea extract can help with weight loss by promoting fat oxidation at rest and during moderately intense exercise. In study A, 12 healthy men performed a 30-min cycling exercise at 60% of maximal oxygen consumption before and after supplementation. In study B, 11 healthy men took an oral-glucose-tolerance test before and after supplementation. The results indicated that with 900 mg of green tea extract supplemented per day, fat oxidation rates increased by 17% during moderate-intensity exercise and can improve insulin sensitivity and glucose tolerance .

In yet another study, male subjects who supplemented with 570mg of green tea extract, for a period of 8 weeks, combined with moderate exercise 3 times per week, found that fat oxidation levels were 24% higher than the placebo, confirming a significant increase in metabolic rate. .

Consequently, more studies are needed to confirm these effects and evaluate the dose and content of tea catechins and caffeine required to achieve expected results on weight loss.

Energy Intake And Food Choice

Subjects were asked not to change their food intake pattern during the 12-wk period. They were instructed to abstain from GT and to use < 100 mL caffeine-containing beverages/d. Furthermore they were asked not to use dairy products within 2 h after/before ingestion of the capsules, because consumption of milk protein inhibits the effect of GT on diet-induced thermogenesis . During the 4 consecutive days before baseline, subjects were asked to maintain their food intake pattern and to record all of the food and drinks they consumed in order to be able to consume exactly the same foods and drinks during the 4 d before their final measurements at week 12. Subjects were stratified by low/normal fat intake vs. high fat intake to examine the effects of GT on the basis of dietary fat intake.

The easiest way to combat feelings of nausea is to take your green tea extract with food. If they persist, you might consider trying a decaffeinated green tea extract like Life Extensions Decaffeinated Mega Green Tea Extract. Green tea naturally contains caffeine, though very few extracts have more than the average cup of coffee per serving.

If youre pregnant or lactating, a decaffeinated green tea extract should be safe to take in low doses but always check with your doctor first. Green tea extract is not appropriate for children or teens.

Can Help With Weight Loss

Green tea extract is rich in catechins, and it contains a decent amount of caffeine. Interestingly, it seems that this combination of ingredients is responsible for green tea extracts modest weight loss properties

Both catechins and caffeine have been shown to assist in weight loss by regulating the hormones that can enhance thermogenesis Thermogenesis is the process by which your body burns calories to digest food and produce heat.

Green tea has been shown to boost this process by making your body more effective at burning calories, which can lead to weight loss

In one older study, 14 people took a capsule containing a mixture of caffeine, EGCG from green tea, and guarana extract before each meal. It then examined the effect on calorie burning and found that the participants burned 179 more calories, on average, in the following 24 hours (

However, results are mixed.

In another well-designed study, 60 adults took 56 mg of green tea extract along with either 28 to 45 mg of caffeine or a placebo daily for 12 weeks. This study found no significant effect on resting energy expenditure or body composition

And, since caffeine is known to stimulate energy expenditure, the modest weight loss effects of green tea extract may be due at least in part to the caffeine itself

In fact, one study determined that green tea catechins dont show any significant effect on energy expenditure when tested against caffeine alone

SUMMARY

May Support Heart Health

Taking green tea extract may protect against heart disease thanks to its anti-inflammatory properties. Green tea contains active ingredients such as antioxidants that help to reduce inflammation that can lead to high blood pressure and clogged arteries risk factors of cardiovascular disease.

Green Tea Extract And Oxidative Stress And Inflammation

Oxidative stress refers to cellular damage caused by free radicals in the body.

Some oxidative stress is necessary and even beneficial, because the damage caused by free radicals encourages the body to adapt to better handle such situations in the future .

Under healthy conditions, your cells get just enough oxidative stress to thrive, but not so much that they suffer permanent damage.

Problems arise, though, when oxidative stress remains too high for too long due to various things like psychological stress, overtraining, or lack of sleep.

If this condition persists, the risk of developing many types of disease rises sharply, including cancer, diabetes, and cardiovascular, neurological, and pulmonary diseases.

One solution is the antioxidant, which is a special type of molecule that neutralizes free radicals in the body, and thus can improve your health and performance in many ways.

The polyphenols in green tea extract are powerful antioxidants, and this is why studies show they can significantly decrease markers of oxidative stress in the body.

This is true even in otherwise healthy people who are following an intense training program .

A good example of this comes from a study conducted by a team of scientists at the Jozef Pilsudski University of Physical Education in Warsaw.

The scientists randomly split up 16 college-level sprinters into two groups:

  • One group took 980 mg of green tea extract per day
  • One group took placebo supplements.
  • Green Tea Extract Side Effects

    What Is Green Tea

    Tea comes in different varieties, but all are derived from the same plant. Green, black, white, and oolong tea are produced from the Camellia sinensis plant.

    Green tea is manufactured by steaming the leaves of the Camellia sinensis plant. It does not go through the same fermentation process used to make other types of tea, such as oolong or black tea, so it retains more of the antioxidants and nutrients found in the plant leaves.

    The Wonders Of Pairing Tea With Food

Green tea is wonderful for its plethora of health benefits, but its also an incredibly flexible beverage that can be paired with a variety of different dishes from all over the world.

    Green Tea Extract As An Appetite Suppressant

    Another huge topic when it comes to the effectiveness of green tea extract in losing weight is that it might be able to suppress your appetite, curb food cravings, and as such, enable you to consume fewer calories altogether.

    Some online sources claim that certain types of green tea can help curb hunger pangs and strengthen vital organs like the pancreas, stomach, spleen, liver, and intestinal mucosa. On the other hand, African hoodia tea is also believed to act as a good appetite suppressant.

    Regarding the scientific evidence of the ability of green tea extract to suppress appetite, studies came to conflicting conclusions. For instance, there are animal experiments that show that EGCG supplements and green tea extract might curb the amount of fat one can absorb from food, but this hasnt been confirmed in humans yet.

    All in all, supplementing with green tea extract may do a better job at helping you burn more fat and calories than actually helping you eat less. With that in mind, focus your weight loss program more around exercise and healthy, low-calorie food choices if you fear that you will accidentally overeat when on a diet.

    What About Green Tea Supplements

    Other Fat Loss Supplements

    While caffeine and EGCG in tea are two of the main fat loss supplements on the market, others are easily accessible and have some evidence to back them up. Capsaicin is a spice that causes the perceived hotness that you feel when eating spicy foods. This pungent extract has been shown to increase thermogenesis and energy expenditure by enhancingyou guessed itnorepinephrine release.

    The issue is that many of these studies have used rats and not humans as research subjects. Thus, you have to be cautious about generalizing these results to humans.

    The data for humans is less impressive. Body fat reductions have been reportedthe issue is that there is a high rate of weight regain, and the participants had trouble sticking to the dosage that is thought to be required for a beneficial effect.

    Another debatable supplement for fat loss is called carnitine. Carnitine is a fat carrier or gatekeeper that helps transfer fat into the mitochondria where it gets oxidized for fuel.

    Logically, it makes sense that if you increase the amount of carnitine, then you could get more fat into the right place to burn it for energy. Unfortunately, that is not the case in 99% of the research on this topic.
