Douglas Laboratories Multi-Probiotic Sinus Support has been discontinued by the manufacturer. Multi-Probiotic® Sinus Support is a unique formula that offers targeted sinus support. This clinically researched formula contains four strains of probiotics and scFOS® prebiotic fiber for immune support, combined with N-acetyl-cysteine (NAC) for its antioxidant and mucolytic properties beneficial for nasal and bronchial health, and the bioflavonoid quercetin to help further modulate immune balance. Ingredients Each serving contains: Proprietary Blend - 280 mg(yielding 7 billion CFU)N-Acetyl-L-Cysteine, Quercetin, Short Chain Fructooligosaccharides (NutraFlora® scFOS®), Bifidobacterium bifidum, Lactobacillus acidophilus, Lactobacillus rhamnosus, Streptococcus thermophilus Other ingredients: Hydroxypropyl methylcellulose (capsule), vegetable stearate. Multi-Probiotic® is a registered mark of Nutri-Health Supplements, LLC, used with permission.NutraFlora® and scFOS® are registered trademarks of GTC Nutrition. Suggested Use Take 1 capsule 3 times daily or as directed by a healthcare professional. More Info. N-Acetyl-L-Cysteine (NAC) is a powerful, natural antioxidant that works in the sinus and nasal passages to support normal mucus viscosity and flow. NAC is efficiently transported into the cell where it is readily converted to cysteine for glutathione synthesis. Thus, supplementation with N-Acetyl-L-Cysteine can raise intracellular glutathione levels. As such, glutathione is a powerful antioxidant to scavenge toxic free radicals and inhibit peroxidation. Quercetin a common type of flavonoid found in various plants that provides antioxidant protection against environmental stresses. In laboratory studies, quercetin supports normal histamine release, which is important for supporting sinus health. Probiotics are supplemental live, beneficial intestinal micro-organisms for gastrointestinal health and immune support. Probiotics have been shown to exert a beneficial support through modification of the immune system host via the gut environment. Clinical trials also suggest that the exposure to healthy microbes through the gastrointestinal tract powerfully shapes immune function. Multiple studies have indicated that multi-strain probiotic blends with lactobacilli, bifidobacterium, and streptococcous can provide optimal support for a diverse range of health needs Research indicates that healthy microflora is critical to promote healthy nasal mucus. There is increasing evidence that oral probiotics support immune function at distal mucosal sites, stimulating a healthy mucosal immune system response. Streptococcus thermophilus combined with L.acidophilus and bifidobacterium have demonstrated positive support of upper respiratory tract health. scFOS, also called short chain fructooligosaccharides, are prebiotics that have short molecular chains. They function as non-digestible fiber that can positively affect selected groups of beneficial intestinal microflora, such as lactobacillus. While probiotics merely add beneficial microflora, prebiotics influence the intestinal environment so that beneficial colonies of microflora can flourish. By aiding the beneficial microflora’s survival, less desirable microflora can have a decreased chance of survival.
