    Customer Questions

    All questions answered by probiotic experts Dr Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Microbiology and Kerry Beeson BSc (Nut. Med.) Nutritional Therapist.

    Can probiotics be taken every day?

    Yes! It’s not possible to overdose on probiotics for immune support as your gut naturally contains trillions of friendly bacteria. Live cultures have been researched for decades, and daily use is both safe and recommended, without risk of dependency or overdose.1,2,3

    How can I boost my immune system?

    Various factors affect immune function, including cold weather or stress, but you can do things to help your immune system. Eat plenty of fruits and vegetables, limit alcohol intake, get a good night’s sleep, exercise daily, and wash your hands properly. As 70% of our immune system is in the gut, consider taking probiotics for immune support during the winter cold and flu season. Optibac Probiotics Immune Support offers all-round gut and immune support.

    Which probiotic supplements are best for the immune system?

    Choose highly researched probiotic supplements containing ingredients proven to support a healthy immune system and your body’s resistance to infection*, such as Vitamin C. Optibac Probiotics Immune Support contains 100% of your daily requirement of Vitamin C, along with one of the world’s most researched probiotic strains, Lactobacillus paracasei CASEI 431®, clinically trialled in thousands of people and found to support immune health4.

    Who should not take probiotics for immune support?

    Vitamin C and probiotic supplements for immune support are generally safe for everyone from one year into old age 1,2. However, they may not be appropriate for adults or children who are immune-compromised – read our safety information for more details. If you have a serious health condition, speak to your doctor before taking any supplement.

    • I genuinely feel my stomach is more settled and less bloated after about 2 weeks. I’m guessing if my gut feels fine something is right which will lead to better health.

      Andy C - 17th April 2022

    • A huge thank you to OptiBac Advisor and Nutritionist Claire Foss for all her support and guidance around my digestive health and OptiBac products. Very happy to say that the gentleness of OptiBac Immunity is working well after a few weeks after many other brands did not agree my digestive system. The secret is trying different products, give them a few weeks each. I know you're eager to reduce your symptoms, but issues like this can take some time to resolve... keep going, and thanks again to Claire for her help.

      Joe - 25th May 2021

    • My wife bought this for us last year and we've both been taking it ever since. So far so good - we're feeling well, good energy and regular in the gut health department!
