Ethylvanillin is a synthetic flavor compound that smells and tastes like vanilla. It is far stronger than the vanillin found in natural vanilla beans. Food and fragrance makers use it to add a bold vanilla note to products.
People do not take ethylvanillin as a supplement. It offers no benefits for energy, focus, or immunity. Because it is only a flavoring, there are no supplement dosage guidelines. You encounter it solely as an ingredient in flavored items. The FDA classifies it as safe in food. Concentrated amounts can irritate the stomach. Do not drink or eat it undiluted.
