I am taking Cosway enzymes drink. Enzymes drink is a fermented product, very good for health. You can make your own too, much cheaper.

It can be made from fruit or combination of fruits. The fruits are tightly kept in a glass container and left for fermentation for about 10 days or so.
Something like making wine. I dunno really know how to explain in English. The enzymes making book which my wife bought was in Chinese. Dunno how to read la. I am a banana.
