The short version
Green tea extract is made from the leaves of the tea plant, Camellia sinensis. Green tea leaves are heated soon after harvest so they stay fresh and keep many of their natural plant compounds, including catechins.
Where it is from
People have grown tea in China for thousands of years, and the habit later spread across Asia and the world. An extract takes the useful part of the leaf and concentrates it, so a small amount of liquid can carry a lot of leaf.
What the label says
On the ingredient graphic, green tea extract is shown as supporting metabolism and natural fat burning.* It heads the list and shares a coffee-and-tea family feel with green coffee beans.
Worth knowing
Tea plants naturally contain some caffeine. If you limit caffeine, check the bottle and ask your doctor.
