The Metagenics UltraFlora Immune Booster is a probiotic blend specifically made to support healthy nasal, sinus, and respiratory function. There are pure strands of Lpa 8700:2 and Lp Heal9, which Metagenics calls “friendly” bacteria. Each bottle contains 30 capsules, and the serving size is one capsule. This is nice in comparison to some other probiotics that require two to four capsules per day for the full CFU count.
The probiotics are non-GMO, gluten-free, and vegetarian so the majority of people can take them. Another plus is that they don’t have to be refrigerated and are shelf stable. While there aren’t many reviews, the few reviews they do have are positive.
