What is Green Coffee?
The Green Coffee Extract is produced by grinding raw unroasted coffee beans and extracting the antioxidants by soaking the ground-up coffee in alcohol. The main ingredient in the green coffee extract is CGA (an antioxidant). It has been found to increase insulin resistance in mice and evidence for its weight-Management benefits is slim, despite the recent publicity.
Thyroid and Green Coffee
The research showed thyroid function can be impaired by high doses of green coffee extract. To clarify further, it was reported high doses of green coffee extract lower T4 and T3, and reduce the activity of the deiodinase enzymes. These enzymes play a crucial role in activating your thyroid hormones.
There have been further studies to show catechins, the main polyphenol compounds found in green coffee can have anti-thyroid effects.
It must be said that so far the studies investigating the potentially harmful effects of green coffee on thyroid function have been conducted on animals. It will be good to see human studies conducted in the future to either confirm or refute the findings.
This, of course, brings to light an important issue when investigating published research. Force feeding laboratory rats a high amount of green coffee extract does not reflect what happens in the real world. No matter what health topic you are researching, human studies are superior to those carried out with animals.
Does Green Coffee really Cure Thyroid?

These included 113 people with thyroid cancer. Along with the thyroid cancer patients, the researchers also tested 138 healthy subjects – who provided a control group.
