Reduces the side-effects of cancer treatment

Doctors have made use of GG probiotic's protective effect on the intestine to reduce the side-effects of:


Cancer patients usually undergo chemotherapy or radiotherapy as part of their treatment programme. These forms of treatment are meant to destroy cancer cells but very often, they destroy normal cells too. One of the most vulnerable organs which is frequently damaged by these forms of therapy is the gastrointestinal tract.

 LACTOGG®’s probiotic strain can induce growth and repair of the cells of the intestinal surface.
Research groups in the US and Canada have demonstrated that this specific probiotic bacterium produces protein substances which reduce inflammation and intestinal cell damage.

Addition of Lactobacillus GG prevented intestinal cell damage.
A = normal cells,
B = cells damaged by inflammation,
C = addition of Lactobacillus GG prevents damage by inflammation.
Arrows indicate areas when cell walls were destroyed.

[Yan et al. 2007]

How should  LACTOGG® be taken?

Supplement amount:

At least 1 sachet or 1 capsule a day.

Since chemotherapy and radiotherapy actively destroy all living cells, it is advisable to increase the number of capsules and the frequency of doses in order to ensure enough live GG probiotic remain to stimulate the immune system and rebuild the intestinal surface. Eg. Patients may take 2-3 capsules 2-3 times a day during active therapy.

There is no "overdosing" of  LACTOGG®.

For best results, LACTOGG® should be commenced before the start of cancer treatment and continued throughout the course of treatment and maintained after completion of treatment to regenerate the intestinal surface barrier.
