High Quality Content by WIKIPEDIA articles! Launched in Europe in 1994, Actimel (also known as DanActive in the United States and Canada) is a `probiotic` yoghurt-type drink produced by the French company Danone. It is sold in 100ml bottles, typically as an 8, 6 or 4 pack, but more recently as a 12 or 16 pack. The main claimed benefit of Actimel is the strengthening of the body`s natural defences through the use of patented bacterial culture called Lactobacillus casei DN-114001, marketed as Lactobacillus casei Defensis or Immunitas(s) and more recently as L. casei Danone. Each bottle is claimed to contain 10 billion of these bacteria. In addition Actimel contains the traditional yoghurt cultures Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus salivarius subsp. thermophilus.
