Scientific Rationale

Psychiatric disorders such as depression and schizophrenia, along with stress and anxiety, have been linked to alterations in gut microbiota composition, including:

  • Decreased abundance of Lactobacillus, Faecalibacterium, and Bifidobacterium [1].

  • Increased presence of LPS-producing bacteria (like Proteobacteria, including Escherichia coli, Klebsiella, Enterobacter), associated with increased gut permeability, systemic inflammation, neuroinflammation, and oxidative and nitrosative stress [1-4].

BIFIZEN® is a food supplement composed of four strains that have been characterized for their:

  • Strong antipathogenic activity against E. coli and K. pneumoniae, with Lacticaseibacillus rhamnosus LR06 and Lactiplantibacillus plantarum LP01 also active against enterohemorrhagic E. coli O157:H7 [5]. Additionally, LP01 is effective against Enterococcus faecalis and Staphylococcus aureus, and Limosilactobacillus fermentum fermentum LF16 significantly opposes the growth of various Candida spp. Strains [6].

  • Anti-inflammatory effects, with LP01 and LR06 exhibiting strong activity [7].

  • Significant antioxidant properties demonstrated for all four strains in in vitro studies [8].

  • The ability of LP01 to produce GABA in an in vitro study [10].

BIFIZEN® has been shown to be more effective than single strains in positively affecting the epithelial intestinal barrier, ROS production, and cell viability in different cellular models, suggesting that the mixture offers a better treatment strategy [11].

In a double-blind, placebo-controlled study on healthy volunteers, a daily dose of BIFIZEN® for six weeks significantly improved mood, accompanied by [12,13]:

  • A reduction in depressive mood state (which persisted for three weeks after washout), anger/hostility (remaining three weeks after washout), and fatigue.

  • Improvement in acceptance (facilitating recovery from depression), sleep quality, and the adoption of avoidance strategies (participants felt better and were more likely to avoid negative thoughts or situations).

  • Increased novelty seeking (a greater inclination towards new experiences).
