A supplement with added Vitamin C designed for those wishing to support their immune system. This strain has been extensively researched in thousands of people and is recommended for daily use, especially in the winter months. It is suitable for those aged 4 years onwards.
I genuinely feel my stomach is more settled after about 2 weeks. I’m guessing if my gut feels fine something is right which will lead to better health.
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 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.
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!
Immune Support can be given to adults and children, from 4 years onwards, with the following recommendations:
Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.
Gut health supplements are not intended to prevent, treat or diagnose any medical conditions. If taking probiotic supplements for gut health, note that these should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you are taking any medications or have a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

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