Theanine Health Benefits
7 Reasons Why It's More Than A Relaxant

Here is what scientists have discovered to date. Enjoy.

Do you know that your brain has 4 wave patterns, with each of them associated with a different state of mind? Going from the lowest to highest frequency:

• At Delta brain waves, you are sleeping deeply.

• At Theta brain waves, you are dozing away.

• At Alpha brain waves, you are relaxed, and yet alert.

• At Beta brain waves, you are awake and very excited. You can also be anxious and stress!

So, if you want to lead a happier, more fulfilling life, you would want more of alpha waves, and less of beta waves.

A paper published in the June 1999 issue of Trends in Food Science & Technology found that theanine reduces anxiety in young woman aged 18 to 22.

They were given either water, 50 milligrams or 200 milligrams of L-theanine once a week. Afterward, their brain waves were measured.

Those who received the highest dose (200 mg) produced more alpha waves.

Further evidence of theanine's relaxing properties come from 4 further animal studies that found that theanine reliably increase dopamine levels in the brain.

What's dopamine?

Dopamine is a hormone that is associated with a feeling of well-being. It is a neurotransmitter that is released during pleasure activities such as food and sex.

Some studies also suggest that theanine may increases your brain’s production of serotonin and GABA (gamma-aminobutyric acid). However, these results are still highly preliminary.

Theanine enhances the ability to learn and remember. It increases concentration, a reason why monks and scholars incorporate tea drinking during meditation and study.

It appears to work quickly and seems to be most effective when you are stressed and your mind is preoccupied by many thoughts. It helps to relax your mind, allowing you to focus on the task at hand.

Because it helps the mind stop racing, it also seems to help promote a more restful, sound sleep. This is because sleep is also not interrupted by random thoughts.

A 2007 study conducted by Doctor Foxe found that it synergise with caffeine to boost the activity of brain neurons.

"As little as 100 milligrams enabled people to focus better on complicated tasks, but only when consumed with 60 milligrams of caffeine — a combination found in roughly 4 cups of green tea," says Foxe more recently.

"There was a profound synergistic effect," he says. "My take is, we're all self-medicating with this."

Tea Improve Concentration

Theanine may bring high blood pressure back to normal, but has no effect on normal blood pressure.

In a 1995 Japanese study, rats with natural occurring high blood pressure were fed theanine. Their blood pressure reduces significantly.

However, the same effects were not observed in rats with normal blood pressure, even though they were given doses as high as 2000 milligrams per kilogram.

Green Tea and Blood Pressure

According to a 2002 paper published by Zhang et all, theanine may improve your heart health by reducing your cholesterol counts in both humans and gerbils.

Another 1997 Japanese study also found that theanine prevents your cholesterols from turning bad through oxidisation (in a process called LDL peroxidation). However, this effect was not as strong as that of green tea polyphenols.

Green Tea and Cholesterol

A 2002 study published by Sadzuka et all suggested that theanine may help improve the quality of life of cancer patients by improving the efficacy of cancer drugs and through its relaxing effects on the mind.

Studies have found that theanine have the following cancer benefits:

• Increase the concentration of anti-cancer drugs in tumours.

• Reduce the concentration of anti-cancer drugs in other issues where they are not needed.

• Inhibit the growth of cancer tumours themselves.

The end result? More effective cancer treatment with less side effects

Green Tea and Cancer - Unproven and Yet Valuable?

A 2003 study conducted by Brigham and Women's Hospital and Harvard Medical School found that it acts as antigens and increases the body’s immunity against cold and flu.

The concluded that drinking tea can promote a strong immune response.

Green Tea and Immunity

Green tea helps lose weight, and according to a preliminary 2004 Japanese study, theanine contributes to this effect.

In this animal study, rats fed theanine diet for 16 weeks had significantly lower body weight, body fats and triglycerides (blood plasma fat).

Finally, if you are not already overwhelmed by the magic of theanine, another 2001 study by the Institute of Traditional Medicine discovered that consuming 200 milligrams of theanine daily helps alleviate PMS symptoms.

The study concluded that the supplement is especially helpful on relaxing the mind.
