Sanatogen is the trade name for a "secret recipe" tonic powder. This was added to a fortified alcoholic wine so that it could be sold in chemist shops as allowed in a loop hole in the UK alcohol licensing laws. Many iron fortified wines being sold in the same way early last century. It remains on sale alongside other "British" fortified wines in supermarkets - with a disclaimer about any health benefits. It is one of those traditional branded products that people still buy for the sick and infirm without any real benefit - ie Lucozade. I bought it for a housebound pensioner for years who claimed it was good for anemia before I pointed out that there was no iron in the ingredient list. The iron fortified version being about 25% more expensive. The Sanatogen trade name is now being applied to a wide range of health/baby products.

A fortified wine is a wine that has had a spirit added to it in its fermentation stage. This adds a different flavor to the wine as well as preserving it. the sweetness of the wine is usually determined by when the alcohol is added in the fermentation stage, the sooner, the sweeter.

Port is a good example, the wine is fortified with the addition of a Brandy (distilled grape spirits), in order to stop the fermentation and to boost the alcohol content. The wine is then stored and aged before being bottled.
Fortified wine does not contain any carbon dioxide. It is made by adding alcohol or brandy to a table wine to increase its alcohol content. If it had carbon dioxide it would come under the head sparkling wine.
Table wine usually has anywhere between 7 and 15% alcohol by volume, and fortified wine has between 15 and 22% alcohol by volume.
