Green tea caffeine content and information
Yes, green tea does contain caffeine. Content varies by the amount of tea used and the length of time the leaves are infused. All things being equal here is a breakdown of the caffeine content of green tea:
Percentage of caffeine in the following beverages:
Coffee- 0.05%
Black tea- 0.05%
Gyokuro- 0.02%
Sencha- 0.015%
Hoji cha- 0.008%
Genmai cha- 0.008%
Green Tea has four important constituents that all work together, caffeine, tannin, essential oils and vitamins. Many people may be surprised to hear that caffeine can actually be beneficial when taken in tea as it works slightly differently from the caffeine in coffee. The good news is caffeine in tea can stimulate the circulation and metabolism via the central nervous system. As more oxygen is pumped to the brain, mental powers are heightened, reactions speed up and muscle function improves.
The tannin in the Green Tea works alongside the caffeine, having a relaxing and stabilising effect. This means the caffeine is absorbed more slowly and prevents that "caffeine shock" we all know too well from coffee.
Green tea contains L-theanine. L-theanine is a healthy amino acid that is only found in tea plants and certain mushrooms. L-theanine directly stimulates the production of alpha brain waves which promotes a state of relaxed awareness, it has a calming effect on the body without making one drowsy.
"There is a way of naturally removing caffeine and preserving the health benefits. Steep the tea for 45 seconds in hot water and then pour off the liquid. Next, add more hot water and steep as you normally would to brew a cup of that tea. Up to 80 percent of the caffeine is released in the first infusion of water so only minimal amounts will remain when you add water the second time. This method eliminates very little of the tea’s flavor and aroma."

Vitamins, minerals, amino acids and herbs taken in too low of a dosage is the same as not taking anything in my opinion. Through research and experimenting with high and low dosages, I came up with what I listed.
For a point of reference: In addition to the supplements I mentioned in a prior post, I also take a multi-vitamin. Multi-vitamins don't have sufficient amounts of the vitamins needed to control high cholesterol levels.
Walking for 30 minutes 1 to 3 times a day will do wonders also in lowering cholesterol levels. Probably food choices and exercise is 80% of the control....................
In the end, I'm offering my experience to you and you ultimately have to make your own decisions.
Example: In the last post, it was mentioned 5% to 10% carbs and 60% to 80% fats in the diet of a low carb dieter. I used to do that and it did nothing special for me. I do fine with 35% carbs, 50% fat and 15% protein. We'll all get different results because we eat differently, different activity, different rest and sleep cylces, climates, etc.... Experimenting and monitoring your results is key to gaining control of your overall health.
I'm not saying the other poster was wrong on percentages, we must all find what works for us. Low carb varies from 1% to 40% in my opinion. I've come to believe, based on my experiences that for me consuming more than 15% protein causes problems for me, but for many up to 30% protein seems to work ok.
A starting point might be considering a 2 to 1 ratio of carbs to proteins and adjust from there. Experimenting and monitoring will let you know what works and what you can live with........
