Wikipedia: Ovaltine
Ovaltine (Ovomaltine originally and in foreign markets) is a brand of milk flavoring product made with malt extract (except in the blue packaging in the United States), sugar (except in Switzerland), and whey. Some flavors also have cocoa. Ovaltine, a registered trademark of Associated British Foods, is made by Wander AG, a subsidiary of Twinings, which acquired the brand from Novartis in 2002, except in the United States, where Nestlé acquired the rights separately from Novartis in the late 2000s.
