An object or drink that's fortified has had extra ingredients added for stronger taste or nutritional value.
You might see this word used when talking about food and drinks. Fortified usually means adding something to make it more helpful, like vitamins or minerals, or even just to give it a stronger flavor. For example, some breakfast cereals are fortified with iron or calcium to help people get the nutrients they need. Some foods also have extra ingredients added for taste, like sugar in fruit juice or spices in soups. In general, the idea is that the item now has more of something, whether it's healthy stuff or just flavor.
