Green Tea may boost Dopamine Levels

Not sure if this has been posted before. Some research shows that green tea is good for Parkinsons Disease and may boost dopamine levels:

Might be better off with something like this:

“We already know how the endocrine mechanism in Mucuna pruriens works: the body converts L-Dopa into the neurotransmitter dopamine. Dopamine increases the activity in the brain centres that regulate sexuality and the production of sex hormones.”

Green tea is has caffeine which is a stimulant. Stimulants tend to boost dopamine levels (the strongest one to my knowledge is cocaine). Caffeine is the second known substance in the world behind cocaine with the most full-body effects. These substances are all going to boost dopamine but they are just stimulants with temporary effects that our bodies adjust to. Leaving us worn out and further back than when we started.

Is anyone feeling better in the long run by dosing with stimulants in the long run?

I don’t believe the articles on green tea implied that the increase in dopamine was from caffiene. The top article states:

Take polyphenols, for instance. These phytochemicals, which give green tea its bitter taste, are powerful antioxidants that have been associated with preventing cancer and heart attacks. Recent research has also shown they may help maintain positive mood states and protect against Parkinson’s disease and other brain disorders.

Green tea can be purchased in a de-caffenated variety so that you can get the phytochemicals without the caffiene. The second article also talks about how green tea affects dopamine levels:

“Normally, dopamine is made an area of the brain called the substantia nigra, and it travels a pathway to a second area of the brain known as the striatum,” Najjar says. Sometimes, however, too much of the dopamine flows back into the substantia nigra. That leaves the striatum with less dopamine than it needs to function properly.

Because dopamine helps muscles move smoothly and efficiently, when a deficiency occurs, symptoms of Parkinson’s develop – including muscle rigidity and tremors.

In the new study, however, researchers demonstrated that compounds known as polyphenols can block the back flow of dopamine, so the transport continues, unhampered, from one area of the brain to the other.

"By keeping the transport of dopamine from being disrupted, polyphenols might be able to reduce the risk of Parkinson’s disease, as well as reduce the progression of the disease in those already affected, " Najjar says.

Decaffinated green tea is not fully decaffinated. They basically soak it a little to get the majority out. Same effect happens if you brew a tea for 1 minute, dump it out, then brew again with the same tea leaves. The caffeine level is simply reduced. Same with decaf coffee.

This study claims that mice (ok at least they’re mammels) fed green tea had increases in both testosterone and DHT:

Green tea tended to increase serum testosterone and DHT levels by 73.8% (P = 0.14) and 194% (P = 0.076), respectively. The combination of SPC and green tea reduced serum levels of DHT (P < 0.05).

Note that the study states that black tea reduces DHT levels:

Mice treated with black tea tended to have a greater serum testosterone concentration (34.4%, P = 0.50) and had a 72% lower DHT concentration than controls (P < 0.05), suggesting that black tea may contain components that inhibit the activity of 5-reductase, an enzyme that converts testosterone to the more bioactive DHT.

Most of the Green tea they sell in the grocery stores in the US and other countries is garbage. There is very little actual green tea leaves in the bags. If it is actual green tea, it ususually tiny bits of it.

I travel to China and Taiwan relatively often and buy my green tea there. It is very good quality and can be purchased much cheaper there as well. Some of what I buy is the actual dried green tea leaves without the bags.

There is a very low number of men that develp prostate cancer in most of the asian countries compared to the US. Many beleive it may be the green tea that actually wards off the cancer in these men.

It could be the soy reducing test also, Asian diets are heavy with it.

Let’s use this thread positively. Everyone who has contributed to this thread needs to sign up for Dr Irwig’s excellent trial.

We NEED PEOPLE to sign up for this. WE NEED NUMBERS. Please.

It is easy. This is how I did it.

1. Print off the consent form. Sign it and fax it to Dr Irwig. The fax number is highlighted. If you have no fax, please email it or scan it to propeciastudy@gmail.com

2. Send an email to propeciastudy@gmail.com with your name and your telephone number.

It took me 2 minutes. Maybe 3 minutes.
THE DOCTORS WE RELY ON TREAT US NEED A SIGNIFICANT STUDY. We need this study.

Please.

I am desperate. I have a brother and sister who I love dearly but haven’t been able to love them properly for 9 years. I now live in a different country to them cos I ran away cos Finasteride ruined me.

I weighed 48kg in 2004 before I started TRT.

I have a lovely girlfriend I can’t have sex with because my dick is too limp cos of Finasteride.

Any of this sound familiar?

Every person in this study is a DIRECT stepping stone to getting this sorted.

PLEASE PLEASE PLEASE fill it out and send it. Yes, you. YOU.

My interview is on Monday 26th April. He phones me. Easy.

Martin, I have read that also. That surely could be a possibility, knowone seems to know for sure why the asian countries have such a lower incedence of prostate cancer.

One aspect of the asian population is body size in general is less than caucasian populations. I believe the main reason for this is the high consumption of anti androgen foods such as soy, rice, fish, and green tea. Soy is strongly anti androgen, rice is high in sterols, fish is high in omega 3 fatty acids, and green tea has components that lower DHT. All of these components have a negative impact on 5 alpha reductase.
Rice, fish, and green tea eaten every once in a while is healthy. But when consumed every single day, will have a profoundly negative effect on 5 alpha reductase.

Who knows, but apparantly what ever they are doing it isn’t lowering their testoserone. I think it’s fair to say Chinese have no trouble procreating with 1.3 billion people.

green tea has components that lower DHT

Could you post a study that confirms this? There seems to be alot of mis-information on hair loss boards that state that green tea lowers DHT. However I could not find any studies backing this up. I did post a study above that shows that it indeed increases DHT and T in mice. This study is quoted quite a bit on bb’s on the internet. Here is another one however it doesn’t refererence the studies it claims green tea lowers dht:

psychology.wikia.com/wiki/Dihydrotestosterone

Green tea, in many studies, has been found a potent DHT inhibitor. However, in one trial using mice, both the testosterone and DHT levels increased. However, if the isoflavones in soy are also ingested, the green tea has a synergetic decreasing effect on DHT.

This study indicates that a combination of green tea, blueberries, Vitamin D, and Carnosine can increase stem cells in bone marrow. Might be worth a try since stem cells can transform into any type of cell in the body. Maybe we could get our damaged cells to regenerate and function normally again…

A combination of blueberry, green tea, vitamin D3, and carnosine, however, increased these stem cells by an astounding 68%.

More on bone marrow stem cells:

The bone marrow (BM) provides the home, or niche, for hematopoietic stem cells (HSC)… When needed, HSC can exit the BM into the circulating blood and migrate into injured tissues for repair or cell replacement.

Finally a good write up from one of the body building sites on green tea, for those that are interested. The side effects section has a good summary of DHT and T level effects from green tea:
