Proven survivability.

A multistrain live bacteria formula developed to be used as part of a daily oral health routine to support oral health and the oral microbiome. 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.
