Great-tasting immune support formula* (+) Helps support immune function and upper respiratory tract health* (+) Offers 30 billion CFU per dose from a combination of five proprietary strains, plus vitamins C and D (+) Helps to maintain proper muscle function and nutrient metabolism (+) Once-daily chewable tablet available in a delicious natural blackcurrant flavor HMF Immune combines proprietary probiotics with vitamins C and D to provide targeted support for the immune system. Each convenient, once-daily chewable tablet provides a blend of five research-driven probiotic strains from both the Lactobacillus and Bifidobacterium genera. As nearly 80% of the body?s immunologically active cells are located in gut-associated lymphoid tissue, an important connection has been demonstrated between the intestines and the immune system. In addition to supporting gastrointestinal health, HMF Immune provides Bl-04, a strain that has been shown in a clinical trial to support upper respiratory tract health in physically active adults. Similarly, it offers CUL-60, CUL-21, CUL-34 and CUL-20, which were demonstrated in a clinical trial to support upper respiratory tract health in children when combined with vitamin C. To further help maintain immune function, HMF Immune contains vitamins C and D. Vitamin C supports the immune system by regulating lymphocyte proliferation, natural killer cell activity and immunoglobulin production, while vitamin D helps control T cell activation, cytokine release and phagocytosis in macrophages. Research demonstrates that vitamins C and D may be especially effective in maintaining immune function in the respiratory tract.*
