Key ingredients deliver outstanding support for healthy sinus function*

The relief for your sinus misery comes from a surprising, yet familiar, source: probiotics. But with thousands of species of bacteria living in your body, it’s critical to understand that the bacteria in your nose and throat are not the same as the bacteria in your digestive system.*

True Results:

  • Helps support healthy sinus function so you can breathe easier*
  • Improves mucus flow and flushes out unhealthy nasal irritants*
  • Stimulates the release of hard, dried up mucus*
  • Reduces drainage and phlegm in the back of the throat*
  • Boosts healthy flora in sinuses*

How Flora Sinus Works for You

Neti pots, nasal rinses and other typical sinus remedies may never give you lasting relief because they don’t address the root cause of all that dripping mucus.*

Thankfully, scientists have identified the misery-making bacteria that live in your nasal passages. Even more important, researchers have taken that information and found targeted probiotic strains that help crowd out the harmful bacteria wreaking havoc in your nose, throat and head.*

We’ve combined a sinus-specific probiotic blend with the top mucus-thinning antioxidant, N-Acetyl-Cysteine, to bring you Flora Sinus, the ultimate solution for relieving sinus misery.*

Flora Sinus gets to the root cause of nasal congestion with a dual-action solution that promotes nasal comfort, while supporting healthy sinus function.*

  1. Nasal Probiotic Blend (240 mg)

    Billions of cells of good bacteria live in your mucosal lining, helping it to work effectively. When you take the right strains of probiotics, they stimulate the immune cells in the mucus of your gut to communicate to the immune cells in the mucus of your nose to fight off unwanted irritants and bad bacteria.*

    Flora Sinus includes Bifidobacterium bifidum and Lactobacillus acidophilus, along with two other sinus-friendly strains, Lactobacillus rhamnosus and Streptococcus thermophilus to keep your sinuses clear and comfortable.*

  2. N-Acetyl-Cysteine (600 mg)

    As a potent amino acid, antioxidant, and detoxifier, NAC is a widely researched nutrient for both traditional and natural medicine. In one study, researchers compared NAC’s mucus-busting abilities against three other mucolytic agents—solvents known to break up mucus. All four solvents were placed directly on thick mucus samples and the results showed NAC outperformed all others in its ability to dissolve mucus, speed mucus flow, improve mucus slipperiness, and reduce mucus stickiness.*

Research Results
Probiotics for Sinus and Nasal Health*

The benefits of probiotics for digestive health are well-known, but now research has shown that certain strains can also benefit your nasal health. Flora Sinus includes four probiotics inspired by groundbreaking research out of Switzerland. In the landmark study published in the American Journal of Clinical Nutrition, scientists showed certain probiotic strains support a healthy balance of friendly bacteria and positive immune microbes in the nose. At the same time, they reduce unhealthy irritants that can worsen sinus conditions and lower your immune response. In fact, the research found that probiotics can reduce potentially harmful bacteria S. aureus in the nose by 19%.1*

In another study published in the Annals of Allergy, Asthma and Immunology, researchers reviewed 12 clinical trials on the use of probiotics for seasonally triggered sinus issues. They concluded that probiotics dramatically reduced the symptoms and severity of seasonal runny noses due to sinus problems.2*

In Flora Sinus you get four, sinus-specific strains: Bifidobacterium bifidum, Lactobacillus rhamnosus, Lactobacillus acidophilus, and Streptococcus thermophilus.*

Featured Nutrient—N-Acetyl Cysteine (NAC):

Flora Sinus also includes one of the most potent mucus-busters available—a powerful antioxidant known as N-Acetyl-Cysteine (NAC). This amino acid is widely recognized as both an immune-booster and a mucus-thinning agent. Initially used to clear mucus in lung patients, research has shown that NAC has the unique ability to flush out harmful irritants and dissolve embedded mucus stuck in your sinuses.*

A breakthrough study published in the Archives of Otolaryngology-Head Neck Surgery found NAC to be a powerful mucus-buster. After treating thick, sticky mucus with NAC, the mucus began to dissolve in just 30 minutes. After one hour, mucus was flowing easily. Even better, the results lasted for four hours. When compared to untreated mucus, NAC improved slipperiness by up to 45 percent for better flow. And, NAC reduced stickiness by up to 30 percent.3*
