7 results about "Fumaric Acid Esters" patented technology

The fumaric acid esters (FAE) monoethylfumarate (MEF) and dimethylfumarate (DMF) are chemical compounds derived from the base compound fumaric acid. Fumaric acid is a food additive commonly found in sweets and cakes. In this chemical state, fumaric acid is poorly absorbed and passes straight through the body without causing any effects.
