  • Lactobacillus acidophilus
  • Lactobacillus plantarum
  • Lactobacillus fermentum
  • Lactobacillus reuteri
  • Lactobacillus casei
  • Bifidobacterium infantis
  • Bifidobacterium breve
  • Bifidobacterium longum
  • Streptococcus thermophilus
  • Protease
  • Amylase
  • Lactase
  • Lipase
  • Inulin

The Lactobacillus species are a very important part of the normal flora in the intestine. As the name suggests they break down lactose, a sugar which is very difficult for some people to metabolize. The presence of the species will make the metabolism of lactose much easier, which place has less stress on the intestine leading to less onset of symptoms. The supplement also contains the enzyme lactase which also breaks down lactose.

The Bifidobacterium species have been shown to play a variety of roles in the human gastrointestinal tract. They are involved with the breakdown of complex sugars some of which humans cannot normally digest. Their effect is helped by the amylase enzyme.

Streptococcus thermophilus also breaks down lactose. The prebiotic inulin stimulates the growth of the natural bacteria in the gut and inhibits the growth of harmful bacteria. This leads to a better balance of the beneficial bacteria in the gut.

The remaining enzymes – protease and lipase break down proteins and fats respectively. Again this place is less stress on the intestine to digest all of the nutrients after the meal which reduces the chance of symptoms occurring.
