Klaire Labs Probiotics Safety
Klaire Lab Probiotics are manufactured to very high quality standards and are formulated with safe and well-researched strains of probiotic bacteria. They use microogranisms that naturally inhabit the gut and have a low risk of adverse effects.
According to Klaire Labs, “Studies show probiotics not only beneficially impact health, but are extremely safe.” Some individuals may experience mild and temporary side effects, such as gas, bloating or diarrhea. These side effects subside after a few days of use.
Probiotics should be avoided by those with immune deficiencies or anyone taking medicines that suppress immune function.
Individuals who have received organ donations and those who use catheters should not take probiotics due to the risk of bacterial translocation. Those with SBS (Short Bowel Disease) or open surgical wounds should also avoid probiotics.
Klaire Lab probiotics are produced in hypoallergenic facilities and are free of both dairy and gluten. They also provide supplements that are appropriate for vegans and vegetarians.
Klaire Labs Probiotics are especially formulated for those with chronic digestive problems. They are well-respected in the industry and provide a wide range of probiotic supplements for different needs.
