NOW Allibiotic CFT is scientifically designed to help support healthy seasonal and year-round immune function. This potent herbal formula is fuelled by Allisure, a clinically-tested, safe and unique form of stabilized Allicin. Allicin is responsible for the healthy immune supporting properties in garlic, and has become an increasingly popular way to support overall wellness. In addition to Allisure, we've added Elderberry Extract, Olive Leaf Extract and Oregano Oil - three natural compounds that have been used extensively to provide healthy immune system support. ImmunEnhancer is a non-digestible soluble fiber from Larch that has been included as a prebiotic supplement and helps in supporting healthy intestinal flora - a key component of healthy immune response.
