An infant swallowing a spoonful of Sanostol food supplement. Colour lithograph by E.B., 195-.

Sanostol is the trade name of a dietary supplement for children that was introduced in the 1930s and became very well known in Germany over several generations. It was manufactured by Promonta in Hamburg. From 1972 it was marketed by Roland Arzneimittel GmbH, the over-the-counter subsidiary of the pharmaceutical firm Byk Gulden, itself a subsidiary of the firm Altana (information current for 1998). The bottle label shown here gives the name Promonta. The product is shown before it evolved in the 1960s to "Multi-Sanostol" containing calcium as well as vitamins ('Sanostol: Long-Seller und Ohrwurm', Altana Geschäftsbericht 1998, pp. 22-24)
