What are Green Tea Extract Flavonols?
Green tea extract is comprised of green tea catechins (GTC) which are in turn made up of four major parts, epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG), these are some of the flavonals within green tea. EGCG is likely what you are most familiar with since it seems to get the most press and accounts for most of the content.
Caffeine is of course contained within green tea, but it need not be present in green tea extract and in my opinion is something better left out, I have plenty of stimulants in my life already.

What does Green Tea Extract do?
Green tea extract, and specifically EGCG has several purported uses:
- Decreases the risk of UV skin damage
- Inhibiting cancer growth
- Weight loss
- Stomach disorders
- Wart remover
- Heart and blood vessel protection
In fact, it’s got so many uses both anecdotally and officially being studied that the list above could be very long indeed.
Much like ALA (alpha-lipoic acid) EGCG increases GLUT-4 recruitment of skeletal muscle and inhibits GLUT-4 in fat cells. Skeletal muscle is muscle that is much stronger than the muscle people tend to focus on. The inhibition of GLUT-4 in fat cells means that it preferentially diverts excess carbs from fat cells to muscle cells!
Another interesting tidbit is that EGCG appears to increase programmed cell death in mature fat cells.
Let me put that into simple terms: It appears to cause actual cell death in fat cells (something unheard of) which reduces the likelihood of rebound (regaining lost weight)!
According to Tim, in the 4-Hour Body dosage is important. Targeting around 300 mg of EGCG three to four times daily could sharply increase weight-loss.
For some anecdotal evidence, take a look at some WebMD reviews about green tea.
With EGCG and it’s purported ability to not only aid in the reduction of fat in fat cells, but its ability to possibly even cause fat cells to die and you’ve got the potential for a killer 1 – 2 combination punch!
Are there Any Side Effects?
If drinking green tea, it’s typically believed that one should refrain from drinking more than five (5) cups of green tea in a day, but that’s primarily due to the caffeine in green tea. In fact many of the side effects that come from drinking green tea are due to the caffeine content.
Green tea and its extract even without caffeine may also present some dangers to those with anemia, glaucoma and liver disease.
As in all things, if you are unsure you should speak to a doctor. If you end up having any kind of strangeness after starting to use any supplements you should consult a doctor and work to isolate the root cause.
Too many times I’ve heard people give up on what is otherwise an excellent medley of natural supplements because of something uncomfortable happening when it may only be one of the compounds within it.
If you are undergoing cancer treatment definitely consult your doctor because EGCG can increase the effects of some drugs.
Experiment, but do it safely under the supervision of your doctor.
Green Tea Extract EGCG (Minus the Jitters Please)
This is the absolute most pure product I’ve been able to find. It contains more EgCG (409 mg) than Tim initially recommends but it is much more gentle on the stomach, has no added constituents and is WAY low on caffeine, something that is very important to me.
The total catechins in this product is 606 mg and it has NO fillers (rice flour is common in many brands)! It is a little more expensive, and I don’t know about you, but I’m willing to pay a bit extra for the added security of what I’m actually putting into my body.
