Green tea extract is a wonder drug. I take it for heart health, for skin health, and according to the study linked and excerpted below, I am now helping to prevent Alzheimer’s disease. Oh, I also take green tea extract to lower my risk of several cancers…I’m a long-term cancer survivor and I’m trying to avoid a relapse or a secondary, treatment-related cancer.
Please don’t come away from reading this post and think that supplementing with green tea extract is the only thing I do for my health. I exercise moderately but frequently, I eat well and I live a healthy lifestyle.
Summary: Two common compounds, green tea catechins and resveratrol, a compound found in red wine, reduce the formation of Alzheimer’s-associated amyloid plaques in brain tissue.

Alzheimer’s disease is the sixth leading cause of death in the United States, affecting more than 6 million Americans, and its incidence is expected to rise in the coming decades.
“The cause of the disease in its most common form, which is not genetically based, is not well understood. This makes treatment difficult, but progress is being made. Using a 3D model of living human brain cells, Tufts researchers earlier this year showed that the common herpes virus could induce plaques in the brain associated with Alzheimer’s disease.
Now, Tufts researchers are working to understand what might slow progression of the disease. They have tested 21 different compounds in Alzheimer’s-afflicted neural cells in the lab, measuring the compounds’ effect on the growth of sticky beta amyloid plaques. These plaques develop in the brains of people with Alzheimer’s.
The researchers found that two common compounds—green tea catechins and resveratrol, found in red wine and other foods—reduced the formation of plaques in those neural cells. And they did so with few or no side effects.
The researchers reported their findings in the journal Free Radical Biology and Medicine.
Some of the 21 compounds tested reduced the disease progression by acting as anti-viral agents—slowing Alzheimer’s induced by the herpes virus…”
“Green tea is widely considered to be beneficial for the brain. The antioxidant and detoxifying properties of green tea extracts help fight catastrophic diseases such as Alzheimer’s. However, scientists have never fully understood how they work at the molecular level and how they could be harnessed to find better treatments….
Preclinical evidence suggests that the green tea compound known as EGCG interferes with the formation of toxic assemblies (oligomers), one of the prime suspects in the early steps of the molecular cascade that leads to cognitive decline in Alzheimer’s patients…
“We all know that currently there is no cure for Alzheimer’s once symptoms emerge, so our best hope is early intervention. That could mean using green tea extracts or their derivatives early on, say 15 to 25 years before any symptoms ever set in,””
