Is Green Tea Good For Testosterone Levels?
We are all familiar with Green tea and its beneficial effects on our overall health..in fact it is thought to be one of the most healthiest drinks around – a fact largely down to its very high concentration of antioxidants.
Green Tea is high in:
- Epicatechin (EC)
- Epicatechin Gallate (ECG)
- Epigallocatechin (EGC)
- Epipigallocatechin Gallate (EGCG)
It is also high in various health giving alkaloids and also caffeine.
Its health benefits are wide reaching, its an effective antioxidant, it is reported to be good for reducing the risks of certain cancers, type 2 diabetes and also boosting cardiac health..
Something that is this good for you must surely be good for Testosterone Levels – Right??
There is a surprisingly large number of studies that have looked at the effects of green tea on certain hormone production, with Testosterone being one of the main subjects.. the studies have actually highlighted a definite link between regular intake of green tea and reduced testosterone production.
It has to be said that all the studies have been carried out on male rodents, but as they share an almost identical endocrine system to us guys, experts believe that the results are pretty typical and they do not expect them to vary too much if and when they actually try this out on human male test subjects
We will cite two clinical studies here in this article..
The first involved male rodents being injected with EGCG (Epipigallocatechin Gallate) the main and key catechin found in green tea…. within 8 days their testicles had actually shrunk by around 15% and their production of testosterone had actually diminished by a staggering 70%
The second and perhaps the most intensive study carried out to date was carried out in India who separated a rodents into 3 groups… each group was given a varying dose of green tea per day:
Group 1 – Dose equivalent to 5 cups of green tea daily
Group 2 – Dose equivalent to 10 cups of green tea daily
Group 3 – Dose equivalent to 20 cups of green tea daily
After 26 days the animals were tested and the hormonal differences found in their blood were compared..
It was found that overall all of the rodents had decreased testicle size, with the rodents in group 1 found to be producing 25% less testosterone, 60% less in group 2 and 78% in group 3
Although a snapshot of the many studies carried out, these results are all commonplace and it does raise the question as to wether you should be drinking green tea regularly if you want to maintain your testosterone levels…
While we believe that drinking the odd cup of green tea here or there will not cause any real effects, we certainly wouldn’t recommend any man drinking 3 or more cups of green tea a day.. certainly until there has actually been some human testing…
