Good yeast vs Bad yeast

Good yeast does indeed offer a wealth of health benefits, including the ability to fight bad yeasts, whereas bad yeast,
such as common pathogen Candida albicans, can be responsible for both superficial and life-threatening yeast infections.


Not only was one of Lesaffre Human Care’s patented strains of Saccharomyces cerevisiae recently proven to have a beneficial influence
in the management of Candida albicans outbreaks but several clinical and real-life studies have also revealed the potential
of one of our patented strain of living yeasts in improving abdominal pain and discomfort in individuals with IBS and other painful digestive disorders.


Probiotic yeasts can also be a safe and natural way for people of all ages to maintain or restore a balanced gastrointestinal flora for optimal gut comfort.

Nutritional Yeast, a nutrient powerhouse


Nutritional yeast has been used by consumers around the world for decades, not only for their overall well-being but also for nails, hair and skin care.


Reliable source of proteins, vitamins, minerals and dietary fibers, nutritional yeast is indeed a trusted partner for a number of consumer groups, ranging from people to everyone aspiring to lead a healthy lifestyle with special needs such as the elderly, pregnant women, etc.

Yeast fractions, fighting against infections


Yeast fractions, such as cell walls containing β-glucans, have proven through in vitro studies that they contribute to the proper functioning of the immune system,
which is key to protecting the body against harmful microorganisms such as pathogenic bacteria and virus.


The above examples are only a few of the many that illustrate yeast’s great potential in providing effective solutions to various health concerns.


With over 160 years of experience in yeast research and biotechnology, Lesaffre Human Care is able to supply
the dietary supplement, pharmaceutical and functional food industry with unparalleled yeast-based ingredients.

Living Yeast, strain-dependent probiotic effects

Lesaffre Human Care’s living yeasts shows great potential in human health with some specific strains of Saccharomyces cerevisiae
revealing a positive response in digestive support as well as women’s intimate health, without the onset of side effects or habituation.


Maintaining a balanced gastrointestinal flora is essential to stay healthy,
not only from a digestive standpoint but also because gut-associated lymphoid tissue represents almost 70% of the entire immune system[1].


Digestive disorders can substantially affect people’s quality of life and ingredients such as ibSium® or Lynside® Pro SCB have been clinically proven
to help ease intestinal symptoms such as, respectively, abdominal pain & discomfort and diarrhea.


Access to effective and natural solutions such as living yeasts is also important in women’s intimate day-to-day support. With over 3/4 of women worldwide
affected by Candida albicans infections at least once in their life, Quatreflora™ Biotic is a great way to maintain a balanced vaginal flora,
helping to manage infections as well as to reduce recurrence.
