Radio Malt was an early to mid-20th-century brand of malt extract preparation that followed the Minadex trend. It is produced by British Drug Houses; it containes vitamin A, aneurine hydrochloride, riboflavin, and calciferol. The contents were sickly sweet, with a consistency between molasses and treacle. It is much loved by George Molesworth, brother of the classic schoolboy character Nigel Molesworth.
