Once-a-day is a probiotic supplement designed to fit into your daily routine. It provides 10 billion live bacteria per capsule, across six carefully selected strains: Bacillus coagulans LMG 6326, Bacillus subtilis LMG S-29373, Bifidobacterium animalis lactis LMG 18314, Lactobacillus casei LMG 6904, Lactobacillus rhamnosus LMG 25626, and Streptococcus thermophilus LMG P-21908.
Each capsule uses an acid-resistant shell to help the bacteria survive stomach acid and reach the intestines. It is free from gluten and soy, and created with minimal, carefully selected ingredients. Suitable for both adults and children aged 4 years and up.
Please note: Once-a-day is a probiotic that may cause slight intestinal discomfort in a small proportion of users during the initial days. This discomfort should resolve on its own within 1 to 2 weeks.
Intoleran was founded in 2008 by Remko Hiemstra, who set out to make eating enjoyable again after navigating his own lactose intolerance. With a strong scientific focus, Remko and his team developed targeted digestive supplements that support the breakdown of specific food components, including lactose, fructose, and histamine. Every formula uses only essential ingredients, avoiding unnecessary additives and keeping digestion support clean and simple. Guided by expertise and a practical, caring approach, Intoleran creates products that help you enjoy food with comfort and confidence, so you can eat freely and live well every day.
