Best Caffeine Pills: Do you need them?

Best Caffeine Pills: Do you need them?
Caffeine is a substance that many consume almost every day in the form of brewed coffee.

According to statistical studies conducted in the United States, out of 24,808 Americans, 89% regularly consume caffeine, with 98% of the caffeine consumed being ingested as a component of various drinks.

According to the results of the same study, the average volume of caffeine daily received by men is 240 mg. per person and women – 183 mg.

Thus, it is obvious that caffeine is an integral part of the daily diet for most people.

If we talk about those who use caffeine in sports supplements, then the dose of the substance changes dramatically: the lower limit of the daily dose corresponds to 436 mg. and the upper – more than 1000 mg.

What is caffeine?

What is caffeine?

Caffeine is a purine alkaloid (1), colorless or white bitter crystals.

Caffeine is found in plants such as coffee, tea, cocoa, Paraguayan holly (mate), guarana, cola, and some others.

It is synthesized by plants to protect against insects that eat leaves, stems, and grains, as well as to encourage pollinators.

Many people see caffeine as a simple stimulant, but this is not so.

A natural chemical compound from the group of methylxanthines (2) has a profound effect on the cerebral cortex, the centers of the sympathetic nervous system, metabolism, energy, and lipid metabolism.

By blocking adenosine receptors, caffeine stimulates the brain centers that regulate respiration and cardiac activity.

It directly stimulates the neocortex, increases mental activity, improves the reaction. It improves transmission in the spinal synapses, enhances the reflexes and activity of motor neurons.

Many of the effects of caffeine are due to its ability to block the phosphodiesterase enzyme in the central nervous system, adipose, and muscle tissue.

Inhibition of phosphodiesterase leads to the accumulation of cGMP (3) in the cells, and this is the main intracellular activator (4).

Caffeine stimulates the secretion of mediators of the sympathetic nervous system (norepinephrine (5)) and enhances the activation of muscle fibers during strength training.

Due to this, more muscle cells participate in the exercises, strength indicators increase, physical performance improves.

Caffeine directly affects metabolism.

It activates the oxidation of fatty acids and glycogenolysis, increases the metabolic rate.

The experiments revealed yet another interesting effect: caffeine “saves” glycogen and increases the role of fatty acids in the energy supply of muscle contraction.

Hence, not only the acceleration of fat burning but also a significant increase in the tolerance of aerobic and anaerobic loads!

No wonder so many people are looking into caffeine pills.

The effect on the central nervous system and higher nervous activity includes the following:

  • Increases concentration and mental performance
  • Enhances reflexes and motor activity
  • Improves the reaction, relieves fatigue and drowsiness
The effect of caffeine on the sympathetic nervous system:

  • Speeds up breathing, enriches the blood with oxygen
  • Expands blood vessels in skeletal muscles, improves the delivery of oxygen and nutrients
  • Promotes secretion of norepinephrine
The effect of caffeine on metabolic processes:
  • Speeds up the key metabolic processes
  • Stimulates lipolysis (splitting and burning fat)
  • Enhances glycogenolysis

Caffeine in tea

Caffeine in tea

Tea, without a doubt, can be called the most popular and common drink on Earth.

Millions of people around the world enjoy aromatic tea and gain strength for the upcoming day.

How can one explain the surge of extra strength and such needed vigor, which can be compared with the energy that fills the body after a cup of coffee?

The answer to this question is quite obvious – caffeine is also present in tea.

If you love to regularly drink tea, then you should keep in mind that unless it is a decaffeinated tea, your tea will have some dosage of caffeine.

This would be especially important if you are considering to also take caffeine pills to ensure that you do not overdose this substance and experience side effects.

We want to note that the level of caffeine in a tea drink is determined not only by the variety of tea but also by the temperature of its brewing as well as method.

Experts say that caffeine is released much faster at high water temperatures.

In brewed tea from unfermented varieties, there is often much less caffeine.

If you increase the brewing time, the concentration of caffeine will increase.

Try to go for around 5 minutes for the preparation of your tea to conserve all the nutrients it has to offer.

Does green tea have caffeine?

A perfectly logical question: in which drink contains more caffeine – in black or green tea?

Does green tea even have caffeine?

Many people would rush with an answer and say that green tea has no or much less caffeine, but this assumption is very inaccurate.

Recent studies conducted by American scientists, analyzing various varieties of the drink, found that the concentration of caffeine is much higher in green tea varieties.

It was experimentally found that in one bag of green has a little more than 70 milligrams of caffeine.

Experimental studies have shown that the highest possible concentration of caffeine occurs in aromatic green tea varieties but without flavors.

The average caffeine capacity in a tea bag is 80 milligrams of caffeine.

Caffeine Anhydrous vs. Caffeine

In 100 mg. of anhydrous caffeine, there are 98 grams of the active caffeine substance.

Anhydrous caffeine is often called “pure caffeine.”

Products with anhydrous caffeine, such as caffeine pills, can be purchased without a prescription in pharmacies, it is also found in most energy drinks, the producers of which seek to minimize the cost of production of their products.

Anhydrous caffeine is stable in compounds, it is highly soluble in liquids.

Anhydrous caffeine is almost a complete analog of natural caffeine, while its production is much cheaper.

Anhydrous caffeine quickly enters the blood circulatory system, and with it – into all cells of the body, breaking the blood-brain barrier within 30-60 minutes.

During this period of time, the concentration of active caffeine in the body reaches a maximum. In an unchanged form, about 2% of the substance leaves our body excreted along with urine.

Caffeine: Brewed or Pill

Caffeine: Brewed or Pill
With the availability of caffeine pills, one would need to know its advantages and disadvantages in comparison to regular brewed coffee before searching for the best caffeine pills.

 

 

 

Here are some points to consider:

  • Caffeine pills are more readily available whenever you need productivity boost, although they do take about 20 to 30 minutes to start working.
  • It is much easier to overdose caffeine pills than brewed coffee
  • Taste. This can be either a plus or a minus, depending on whether you love brewed coffee or not
  • Pills do not bring the benefits of communication over a cup of coffee
  • With pills, you will be consuming only caffeine. No water, oil, sugar, milk, etc. that are usually added to the brewed coffee. This can be a great advantage to people who are on a diet or want to limit their bathroom trips
  • If you suffer from heartburn after drinking black brewed coffee, caffeine pills can help you to avoid that, although reflux symptoms still appear for some individuals.

Caffeine dosage

For a healthy person, caffeine intake is absolutely safe.

It should be noted that this statement is true only in cases where tea is used reasonably. How much caffeine is safe for humans?

If you are guided by confirmed medical data, then you can take from 100 to 200 mg of caffeine per serving.

A safe daily dosage for most people is about 400 mg of caffeine.

However, you should remember that coffee, tea and caffeine are not the only sources of caffeine.

Thus, to prevent caffeine overdose, keep of track of foods such as hot chocolate, coke, chocolate and protein bars as well as energy drinks.

A cup of tea averages about 85 mg of caffeine.

About 12 cups of tea can be drunk daily.

3-5 cups are completely harmless.

What about caffeine pills?

The answer would depend on the pills you choose, so you should carefully read the instructions.

Usually, one caffeine pill is equal to one cup of brewed coffee or 100 to 200 mg of caffeine.
