OptiBac 'For daily immunity'
‘For daily immunity’ is now a new and improved formula; a unique combination of Lactobacillus paracasei CASEI 431® and vitamin C.
This product is suitable for those looking for a natural immune support in preparation for the winter season, particularly those who often suffer with colds & flu.
We are excited to introduce this strain to the OptiBac range as L. paracasei CASEI 431® has been studied in numerous clinical trials on thousands of people. This strain is typically studied on its own as a single strain, so we decided to keep it that way.
Moreover, this product is safe during pregnancy, suitable for vegans and guarantees 5 billion live cultures per capsule, at expiry.
Research into the human microbiome is constantly evolving, these are exciting times, especially as we’ve been following the research for years.
Remember, it is important when looking for a live cultures supplement to look for the best, most researched strains for your needs. No strain is the same, be sure to choose one with proven results.
More about OptiBac
At OptiBac we have always focussed on research. We only use the best, most clinically studied strains because we understand that the quality of the strain is reflected by the research supporting it.
Healthcare professionals can read scientific research on L. paracasei CASEI 431® on the Probiotics Database.
Please note that as of January 2018 OptiBac ‘For daily immunity’ comes with new & improved ingredients. The new product now contains one live cultures strain as opposed to four. This strain, Lactobacillus paracasei CASEI 431®, is extremely well-researched. Natural plant extracts (pine bark extract, grape seed extract and green tea extract) have been removed from the formula making the new ‘For daily immunity’ vegan and also suitable for use by pregnant women. Overall, we feel that the new supplement is of superior quality, and are confident that our customers will love it, too.
For daily immunity can be given to adults and children (from 12 months upwards) with the following recommendations:
- Take one capsule daily, preferably with breakfast, or as professionally directed.
- Drink plenty of water with this OptiBac supplement.
- For anyone unable to swallow capsules, the content of the capsule may be mixed with a cold meal or beverage.
- For daily immunity can safely be taken on an ongoing basis.
Like the rest of the OptiBac range, this does not require refrigeration.
Store away from direct sunlight.
Live cultures are not recommended for those with serious medical conditions eg. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or to patients with open wounds following major surgery; unless under a doctor's care. Furthermore, pregnant or breastfeeding women should consult their doctor before taking Saccharomyces boulardii or 'For travelling abroad'.
