The US FDA does not currently offer a specific definition of a functional food. However, the widely used description offered by the U.S. Institute of Medicine states that a functional food is one that “may provide a health benefit beyond the traditional nutrients it contains” (U.S. Institute of Medicine, J. ADA 1995).

Isabella’s Functional Muffins are designed to offer specific health benefits to the consumer. Our three varieties are Activate, Optimize, and Revitalize.

Activate – a probiotic raisin bran muffin containing GanedenBC30 that is designed to optimize digestive tract function. The World Health Organization describes a probiotic as a living microorganism that benefits its host when present in adequate amounts. Isabella’s Activate muffin contains friendly bacteria in the proper amounts to help improve gut health and function. They are also an excellent source of insoluble fiber.


Optimize – loaded with blueberries, blackberries, and raspberries, and with Acai and pomegranate extract, this antioxidant-rich muffin helps prevent cell destruction by inactivating free radicals. It is believed that this action helps to slow the aging process and prevent disease. The muffins are further enriched by the addition of the antioxidant vitamins C and E to help improve immunity and heart health.

Atoms are stable when all their electrons exist in pairs. Free radicals are atoms with unpaired electrons. They are thus unstable and highly reactive, as they seek to find other electrons with which to pair up and achieve stability. They often begin a chain reaction of cell destruction as they “attack” other molecules to obtain the needed electrons. The molecules that lose electrons in turn become free radicals.

In the body, free radicals are formed when oxygen breaks the bonds between stable paired electrons. This reaction is called oxidation. Antioxidants help prevent cell destruction by combining with the free radicals that would otherwise damage cells to “steal” an electron.


Revitalize – this hearty peanut butter and chocolate chip muffin helps to increases energy. It is enriched with added Vitamins B6 and B12, and energy boosting compounds such as guarana, taurine, inositol to further increase energy, support cellular regeneration, and promote healthy organ systems, including the nervous system and skin.
