Frequently Asked Questions

Probiotics are live microorganisms that, when consumed in adequate amounts, can support a healthy gut microbiome. A diverse microbiome plays a vital role in digestion, nutrient absorption and overall wellbeing. While not a cure-all, probiotics can contribute to maintaining gut health - especially helpful during times of imbalance, like after antibiotics or changes in diet.
Each Bio-Culture Capsule contains 50 billion CFUs (colony-forming units) from 16 well-researched bacterial strains, including the studied Lactobacillus and Bifidobacterium. That means a concentrated, diverse dose, all delivered in one simple, daily capsule.
One capsule 30 minutes before your breakfast is the best way to take this supplement, as it’s most effective on an empty stomach.
Everyone’s gut is different so timing can vary, but most people start to feel the benefits after a few weeks of consistent daily use. For optimal support, we recommend taking Bio-Cultures daily for at least 4–12 weeks.
Taking a probiotic regularly can help maintain the balance of good bacteria in your gut, supporting digestion and contributing to a happy, healthy microbiome. Like all good habits, the key is consistency - your gut thrives on routine, too! Fun fact: your gut produces neurotransmitters, such as dopamine and serotonin, also known as your ‘happy hormones’. So, a healthy body can equate to a healthy mind.
“CFU” stands for colony-forming units, which refers to the number of viable, live microorganisms in each capsule. 50 billion CFU (a healthy, efficacious dose) means you’re getting a high-strength serving designed to deliver maximum support to your gut microbiome - all in one daily capsule.
