Sytrinol is a patented formula (US Patent # 6,239114 and # 6,251,400) derived from citrus and palm fruit extracts. It is a combination of citrus flavonoids and palm-sourced tocotrienols that can exert potent antioxidant effects.

The polymethoxylated flavones (PMFs) are a group of compounds that are derived from the peels of citrus fruits. These are the predominant flavonoids found in Sytrinol. The two most common are tangeretin and nobiletin. These compounds, on their own or in combination with other nutrients, have an ability to affect the metabolism of lipids.

The second major component of Sytrinol is a class of compounds known as tocotrienols. Tocotrienols are fat-soluble vitamins related to the family of tocopherols, derivatives of vitamin E. They are potent free radical scavengers that may have the ability to modify certain cardiovascular risk factors.
