Fans of tonic drinks of purely natural origin pay special attention to tea cultures. A variety of varieties, differing in taste and aroma, always help to gain an additional charge of vigor, inspiring new achievements.
One of the factors causing a similar reaction of the body & mdash; presence of a purine alkaloid in the composition of microelements. It is this component that creates a positive mood, enhances tone.
However, not all lovers and connoisseurs know for certain whether there is caffeine in green tea, and how much it is contained in one cup of the drink. It's time to delve into this question and get detailed answers.
Overview
As you know, black coffee & mdash; ristretto, espresso or americano & mdash; has an almost instantaneous effect on the nervous system.
The reaction occurs after a couple of minutes, manifesting itself in the form of a rapid heartbeat, activation of brain activity and increased performance & mdash; but this effect does not last as long as most coffee lovers would like.
Tea influence, in turn, manifests itself in a different way & mdash; softer and more discreet.
Green tea content & mdash; the combination of caffeine and tannin, which forms thein, which has a more delicate effect.
The drink does not cause sudden changes in blood pressure, and does not force the heart to go into an enhanced mode of operation. Instead, it dilates blood vessels, improves the functional state of the nervous system, and clarifies thinking.
Benefits highlighted by experts include:
No accumulation effect in the body.
Reduced concentration in infusion compared to dry sheet.
Slow digestion and rapid elimination.
Carefully stimulate the heart and CNS.
It is peremptory to state in which variety of green tea the caffeine content is greater than in coffee or other varieties, it would be wrong & mdash; it all depends on the chemistry.
Not only the types of tea bushes differ, but also the processing methods, the duration of fermentation, as well as other characteristics that determine the final combination of components.

Benefits and harms
Regardless of concentration, green tea infusion is characterized by a certain set of physiological effects that occur when it is consumed:
Energy release and fat cell burning.
Stimulation of adrenaline production.
Mild diuretic effect.
Smooth pressure increase & mdash; depending on strength.
Exciting and invigorating.
Inclusion of the drink in the diet on an ongoing basis & mdash; without excessive enthusiasm & mdash; provides additional positive effects on the body.
Advantages
Studies confirm that when consumed in moderation, caffeine-containing foods improve memory and slow down the destruction of brain cells.
In addition, the risk of inflammation as well as age-related changes is reduced.
Cons
Negative side effects are caused by too frequent and large dosages, leading to a depletion of the nervous system, suppression of intellectual and physical activity.
It is necessary not to exceed the recommended daily dose of green tea, since too much accumulation of alkaloid can lead to sleep disturbances and exacerbation of nervous states, increased anxiety.
Is there a lot of caffeine in green tea
The concentration of the stimulant depends on both the raw material treatment method and the preparation method.
Young shoots contain the largest volume, up to 5% of the mass value.
Up to 85 mg of an invigorating trace element is usually present in a dish of such an infusion.
In mature leaves, this decreases to about 1.5%, which reduces the content per medium portion to 60 mg.
In addition, the chemical composition is also influenced by the place of growth & mdash; plantations located in the highlands are characterized by colder conditions, which not only slows down the growth rate of the plant, but also leads to the accumulation of alkaloid.
What's stronger & mdash; black tea or green
If we take the averaged indicators & mdash; the second option will be more effective in terms of stimulating the nervous system and increasing tone.
Of course, the result is affected by the duration of exposure, the ratio of liquid to brew, as well as the individual perception by the body of the trace elements contained in the drink.
To evaluate the effect yourself, you should prefer classic leaf varieties.
So, for example, among the clients of & laquo; Russian Tea Company & raquo; they are especially popular among those who want to get rid of the feeling of fatigue and increase their own performance:
Лунцзинь — growing in Zhejiang, and characterized by prolonged preservation of a sweet taste, morning dew aroma, rich green color and attractive appearance.
Golden ginseng & mdash; a natural blend that combines Chinese tea tree leaves and grated ginseng root, not only providing a pronounced bouquet and slightly spicy flavor, but also contributing to improved concentration.
However, the final choice of the appropriate variety primarily depends on personal taste preferences.
For those who want to approach this issue in the most careful way to get the most useful drink, it is worth considering a few nuances.
What to watch for
Among the parameters evaluated by specialists in determining the approximate amount of caffeine in green tea are:
Raw material composition. Large-leaved varieties are traditionally inferior in thein concentration to young kidneys and shoots.
Processing technique. The weaker the fermentation & mdash; the higher the content, since prolonged exposure reduces the mass caffeine fraction.
Collection season. The most tonic infusions are obtained from varieties collected in the spring, which is again due to the early stage of maturation.
Climatic conditions. Cold regions, especially in mountainous areas, provide a longer cycle of growth and development of tea bushes, which ultimately causes the accumulation of alkaloid in the leaves.
To get detailed advice about the specific features of a particular variety presented in the catalog & laquo; RC & raquo;, just contact the company's specialists who are always ready to answer any questions you are interested in.
How to lower caffeine levels in green tea
Despite the delicacy of the effect characteristic of infusions and decoctions, increased susceptibility can spoil the positive tea drinking experience. There are special recommendations for this.
7 Tips to Help Reduce Thein
When choosing a brew, it is worth clarifying its composition and origin. Elite varieties consisting of early shoots are characterized by the greatest strength. Also, for those who prefer not too strong option, shaded species are not suitable, such as Matcha .
Own body reaction & mdash; the main criterion for assessing perception. Experts recommend limiting the daily dose to no more than 300 mg, but in some cases it will be more useful to reduce the frequency of tea ceremonies.
When ordering a new variety of tea, you should pay attention to varieties that initially contain a minimum proportion of stimulating substances. For example, Japanese buncha belongs to the classes collected at the later stages of maturation, due to which its caffeine content is reduced to hundredths of a percent.
Packaged and powder mixtures & mdash; not the best choice for those who want to reduce the concentration of thein, since not all manufacturers monitor the quality of the processing of the raw material mass during the blending process.
The first infusion of green tea is recommended to be drained in a minute after pouring hot water & mdash; during this period, about 80% of all alkaloids contained in the brew manage to stand out.
In case of acute reaction to tea drinks, you should pay attention to alternative options for natural brewing & mdash; karkade, camellia, etc.
The total brewing time should not exceed 60 seconds. The longer the leaves are aged in liquid & mdash; the more concentrated the dose of thein obtained during tea drinking becomes.
Cooking algorithm
In accordance with ancient Chinese traditions, it is almost impossible to imagine a real ceremony without a gaiwan and a clay kettle.
However, you can make a noble drink correctly at home using a flask, thermos, French press or other utensils.
Main & mdash; adhere to basic rules:
Capacity must not exceed 0.3 liters.
Before starting, the walls are rinsed with boiling water to keep warm.
A sheet placed inside should be slightly shredded for even coverage.
First brew & mdash; for heating and washing of plaque & mdash; merges immediately.
Traditionally, green teas are brewed several times, allowing you to get a rich and tasty infusion that gradually changes organoleptic properties. At elevated temperature, the effect of polyphenols and catechins that neutralize thein is more effective, which partially softens the tonic effect.
More useful information
In order for tea drinking to be beneficial, you should maintain a reasonable balance, as well as listen carefully to your own body:
Absorption of the active substance is primarily determined by the specific metabolic processes, as well as individual tolerance.
Tannin itself does not provoke an increase in pressure & mdash; such a reaction is determined by the concentration of the infusion and the sensitivity of the body.
For older people, excessive consumption of foods containing caffeine increases the risk of calcium leaching.
Even the strongest infusion does not sober up or stop the state of intoxication & mdash; on the contrary, in some cases there is a risk of additional stress on the heart and blood vessels.
In addition, it is scientifically proven that men are less susceptible to the alkaloid effect, and the overall threshold of susceptibility gradually decreases with age.
How the reaction occurs
The tonic substance, entering the human body, primarily blocks the functions of adenosine, as it is an imitator of this hormone that provokes drowsiness.
As a result & mdash; increased tone, activity and concentration, improved mood and improved performance.
Along the way, caffeine stimulates the production of adrenaline, resulting in an increase in heart rate and pressure, as well as the intensity of blood flow. In addition, dopamine levels are rising & mdash; a neurotransmitter whose task is to ensure conductivity.
Effects on the nervous system
CNS excitation, as a reaction to taking a dose of a stimulator, at standard indicators does not pose a threat to human health.
The acids present in the blood plasma increase the level of the heat exchange process, thereby suppressing hunger and creating a warming effect.
Caffeine for weight loss
Stimulation of calorie processing, or thermogenesis, is caused by the breakdown of glycogen.
The released energy provides a long-lasting charge of vigor that lasts for 2-3 hours.
Performance in sports
The tonic also increases exercise performance by promoting calorie burning and by converting fats into a resource used by muscles during exercise.
However, in this case it is important to monitor the general state of the body, first of all & mdash; cardiovascular response to a drunk dose.
Contraindications
The list of limiting factors, the diagnosis of which necessitates the rejection of caffeine-containing products, includes high blood pressure, vascular and gastrointestinal pathologies, as well as atherosclerosis. It is not recommended to abuse tea and coffee during pregnancy and lactation.
Content and consumption standards
The question of what daily dose of alkaloids can be considered acceptable to humans is still controversial and relies more on the individual characteristics of the tea connoisseur.
For beginners to get acquainted with this drink, at first it is advisable to follow the reaction of their body. 300-400 ml will be enough for them, that is, no more than 2-3 small cups.
If you are a connoisseur of green tea and have been drinking it for a long time, then 1000 ml/day will not be a large amount for you.
However, the concentration of the substance must be taken into account, as well as individual specifics.
Caffeine content of different teas
Measures typically expressed as a percentage of weight vary even within the same class, so you should refine the key characteristics for each individual collection.
So, for example, in various types of puer, the share varies in the range from 1.5% to 5% & mdash; depending on the size of the leaf and the location of the plantation. & nbsp; Pressed and large-leaf varieties have a lower strength.
For mate, 1.8% is considered normal, which is due to the absence of catechin.
Oolongs are fermented in a variety of ways, but are generally not too saturated with thein.
Is there decaffeinated green tea
There are two ways to completely neutralize the alkaloid effect.
The first, more expensive and environmentally friendly method & mdash; treatment of raw materials with liquefied gas under pressure, the so-called & laquo; hiss & raquo;, as a result of which the taste remains unchanged and the active substance is filtered out.
Second & mdash; use of ethyl acetate, draw-off; microelement from leaves when soaked.
It is worth noting that such processing, although cheaper, reduces the content of useful components by 60-70%.
In addition, neither option guarantees 100% withdrawal of the stimulator.
Concentration is minimized, but can still trigger allergies if you have a predisposition.
What is the risk of an excess of caffeine in green tea
The negative symptoms characteristic of caffeine overdose occur when the consumption rate is exceeded. Obvious manifestations include:
Headache and nausea attacks.
Heart palpitations.
Anxiety and sleep disturbance.
Constant thirst.
Indigestion.
Any deviations from the usual condition that persist for several days are the basis for contacting a doctor.
How many cups can you drink per day
As we discussed, one mug contains 30 to 100 mg of the item.
The daily dose tolerated by a healthy adult varies from 800-1000 milliliters, which is equal to 10-15 cups.
But we do not recommend overusing tea drinks, but quenching your thirst with clean water.
Let's summarize
So, now you know for sure whether green tea contains caffeine or not, and whether it contains other trace elements that affect the body.
It is important to remember that in any business the main thing is & mdash; observe a reasonable measure. With a competent approach to organizing and holding a tea party, even the strongest and most saturated varieties will give you extreme pleasure.
