Key Benefits

  • Contains strains studied for their effects on epithelial barriers.

  • Supports the gut-brain axis.

  • Proven to reach the gut alive.

Bio.Me Barrier is a clinically researched live bacteria formula designed to support microbiome balance for the gut-brain axis. The gut-brain axis is the communication network between the gut and brain, influencing mood, cognition, and overall wellbeing. It contains specific strains, including B. bifidum, L. acidophilus, L. brevis, and Lc. lactis subsp. lactis, which have been studied for their role in strengthening epithelial barriers. Also containing Probioact Technology, PROBIOACT® stands for probiotic activity and is a technology developed by Winclove, focusing on the ingredients that surround the probiotic bacteria.

The PROBIOACT® Technology consists of product-specific protective and nutritional ingredients, which have been extensively tested to: keep probiotics stable at room temperature and maintain high cell counts using a water-soluble carrier matrix of starches and maltodextrin; protect against osmotic shock during rehydration with minerals; safeguard against stomach acid, bile, and digestive enzymes in the GI tract using vegetable proteins; and optimise metabolic activity at the right time and place with an enzyme, prebiotic, and vegetable protein nutrient resource.

Each of Invivo's supplements is meticulously formulated to modulate multiple human microbiomes, undergoing rigorous scientific research and testing to ensure efficacy and safety. Their nutritional products are certified GMP and non-GMO, designed to support overall health and harmony within the body.

Invivo is a life science company dedicated to advancing human microbiome health through innovative testing and supplements. They collaborate with healthcare practitioners, providing cutting-edge bioscience solutions while championing community, transparency, and sustainability. As a certified B Corp, Invivo is committed to ethical business practices and using their platform to drive positive change in healthcare.
