        The Most Frequently Asked Questions

        Does it need to be refrigerated?

        No! Spore-forming probiotics are naturally stable and can be stored at room temperature away from light. They have a shelf life of up to 5 years and are convenient to take with you when you're on the go.

        What is the live bacterial count?

        Each 2-capsule serving contains 4 billion CFU of a Bacillus complex. The spore form is extremely stable at room temperature, ensuring the live bacterial count is maintained without the need for refrigeration.

        Can I take this while on antibiotics?

        Yes, but we recommend waiting at least two hours after taking antibiotics. The spore structure helps reduce the damage antibiotics cause to the gut microbiota.

        How long does it take to feel the effects?

        Most users notice an improvement in digestive comfort within 2–4 weeks. A 60-day clinical study showed that it effectively relieves abdominal discomfort and supports regular bowel movements.

        What type of probiotic is MegaSporeBiotic?

        It is a whole-spore probiotic blend made from natural spore-forming strains. Unlike conventional live-culture probiotics, it is resistant to stomach acid and bile and remains active even without refrigeration.

        Is there clinical research supporting this strain?

        Yes, the formula has been validated by 10 peer-reviewed studies, which show that it enhances gut microbiota diversity, promotes the growth of beneficial bacteria, and reduces the number of potentially harmful bacteria.

        Collapsible rowCan it help with constipation and diarrhea?

        Yes, it helps regulate the balance of gut flora, which improves bowel motility and relieves constipation, diarrhea, and bloating.

        Will I experience bloating or increased flatulence after taking this?

        A small number of people may experience mild flatulence at first. This is a normal part of the gut flora adjustment process and usually resolves on its own within 1–3 days. There is no need to worry.

        What is the main difference between this product and regular probiotics?

        Most regular probiotics are inactivated by stomach acid and struggle to reach the intestines; however, its spore structure allows it to survive stomach acid and bile 100%, germinate, and colonize the intestines, resulting in greater efficacy.
