Innovative Probiotic Lactic Yeast for the pharmaceutical, nutritional and agricultural industries

Gut Health

"Modern" lifestyle obliges us to find the right natural aid to counteract its negative consequences on our microbial balance, digestive health, immune health and mood. In multiple research and clinical studies, Turval B0399 reduces lifestyle induced gut discomfort when consumed daily. Clinical trials, described bellow, demonstrate that it can ameliorate IBS-like symptoms (occasional diarrhea, constipation and bloating) improving the quality of life and the overall wellbeing.
Besides, the particular enzymatic activity of this yeast helps digestion of complex carbohydrates such as lactose and pectans and may prevent the associated digestion problems.

  • Irritable Bowel Sindrome

    Trial#132 Clinical results of treatment with the lactic yeast Kluyveromyces B0399 for Irritable Bowel Sindrome. This study, based on the gathering of symtomatological data before and after the treatment, demonstrates that the prolonged use of Kluyveromyces marxianus fragilis B0399 significantly improves the clinical picture and above all improves the quality of life of these patients.

  • Trial#125: Evaluation of the effects of a yogurt containing Kluyveromyces marxianus fragilis B0399 in patients suffering from Irritable Bowel Syndrome—a randomized, placebo controlled clinical study (abbreviated text)

    This study evaluates the effects of a yogurt formulated with a new lactic yeast,
    Kluyveromyces marxianus fragilis B0399, in patients suffering from IBS. A double blind, monocentric study, controlled against a yogurt containing S. thermophilus, Lb. bulgaricus and Bifidobacterium lactis BB12, in parallel groups, in patients affected by IBS. The subjects assigned to the treated group presented a global satisfaction significantly superior compared to the control group.
