Xlear Inc. centers on proactive health—staying healthy through transformational hygiene. Xlear xylitol-based products support that goal.
From the time that Ignaz Semmelweiss first wrote about the need for physicians to wash their hands between patients and the time that it became the standard of care (or mandated because it wasn’t being done) was 150 years. Semmelweiss was ridiculed, laughed at, and discredited, but history proved him correct. Washing our hands and our nose are simple hygienic ways that we can stop the spread of bacteria and viruses.
Nasal hygiene is more important to our health than washing our hands. Washing our hands helps stop the spread of infections, but how often do you really get sick through your hands? Practically zero. You get sick when you touch your hands to your face, your nose, your eyes where bacteria and viruses can easily enter the body.
Wouldn’t it make more sense to wash our nose with something that blocks viral and bacterial adhesion?
The nose is where bacteria and viruses enter the body. Nearly 75% of the visits to primary care physicians in the U.S. are related to upper respiratory issues. We can bring that number down significantly if we start washing our nose.
Xlear Nasal Spray was developed by Dr. Lon Jones who wanted to better serve his patients with upper respiratory illnesses and conditions. After reading the extensive research done in Finland on the benefits of xylitol, Dr. Jones developed a xylitol nasal spray to treat his patients with persistent upper-respiratory infections. He successfully treated his granddaughter’s ear infections and soon began dispensing the solution to other patients with ear, nose, and throat issues.
Let’s transform our hygiene and make it more effective. Wash your nose with Xlear.

Anti-Adherence of Bacteria – 1998
This study found that xylitol blocked adhesion of bacteria to epithelial cells, showing that xylitol inhibits bacteria from sticking to tissue, which allows the body to wash them away.

Xylitol Nasal Irrigation in the Management of Chronic Rhinosinusitis – 2011
In this pilot study, researchers wanted to find out if irrigating the sinuses with a water-xylitol solution would improve symptoms of people suffering from chronic rhinosinusitis. They concluded, “Xylitol irrigations result in greater improvement of symptoms of chronic rhinosinusitis as compared to saline irrigation.”

The Three Stages of SARS-CoV-2 Infection – Jul. 2020
The paper’s authors show that like other illnesses which affect the lungs, the SARS-CoV-2 virus has three stages of infection, and if left unchecked, it could cause irreversible damage to lungs. They argue medical professionals must give greater attention and treatment in the earlier stages of infection.

Using Nasal Sprays to Combat SARS-CoV-2 – Sept. 2020
Researchers concluded that using a nasal spray that deactivates the SARS-CoV-2 virus in the nose, “may not only prevent person-to-person spread of SARS-CoV-2, but may also diminish the severity of disease in patients by limiting spread and decreasing viral load delivered to the lungs.”

Nasal Irrigation Reduces Symptoms Related to SARS-CoV-2 – Sept. 2020
In this interim analysis, researchers evaluated the effect irrigating the nose and sinuses had on reducing symptoms related to SARS-CoV-2. They found, “The effect of nasal irrigation on symptom resolution was substantial, with nasal congestion and headache resolving a median of 7 to 9 days earlier in the intervention groups. Our analysis suggests that nasal irrigations may shorten symptom duration and may have potential as a widely available and inexpensive intervention to reduce disease burden among those affected.”

Further Evidence of Xylitol’s Effectiveness Against SARS-CoV-2, H1N1, and Other Viruses – Jan. 2021
In this study researchers used an electron microscope to take pictures of xylitol’s and grapefruit seed extract’s (GSE) interaction with the SARS-CoV-2 virus. They concluded, “Combination therapy with GSE and xylitol may prevent spread of viral respiratory infections not just for SAR-CoV-2 but also for future H1N1 or other viral epidemics. GSE significantly reduces the viral load while xylitol prevents the virus attachment to the core protein on the cell wall.”

Comprehensive Literature Review of Intranasal Therapy Against SARS-CoV-2 – Jan. 2021
In this review, researchers looked at all the studies talking about intranasal therapy in fighting against SARS-CoV-2. They concluded, “Based on the literature review, it is encouraging to note that studies reviewed note that using nasal spray with antiviral properties has promising efficiency and safety in the treatment and prophylaxis against SARS-CoV-2…We propose that intranasal administration of antiviral and virucidal therapies decrease the viral activity in the nasal pathway, thus preventing disease transmission, expedite recovery of patients, decrease severity of symptoms, reduce hospitalization, and mortality.”

Inhibition of severe acute respiratory syndrome coronavirus 2 replication by hypertonic saline solution in lung and kidney epithelial cells – Sept. 2021
In a study performed at the University of São Paulo, researchers found that a hypertonic saline solution inhibits the replication of SARS-CoV-2. They found that, “[The] data show that 1.2% NaCl inhibited virus replication by 90%, achieving 100% of inhibition at 1.5%.” Researchers are excited by the results because they show that a saline can be an effective, cheap option to reduce the severity and longevity of the virus. Researchers found that saline has this effect by inducing cellular processes that reduce energy stores, which hamper replication.

Rapid initiation of nasal saline irrigation to reduce severity in high-risk COVID+ outpatients: a randomized clinical trial compared to a national dataset observational arm – 2021
Researchers wanted to better understand if nasal irrigation would result in fewer hospitalizations after a positive COVID-19 test result. After conducting a study with 79 participants, researchers found that, “Patients who initiated isotonic saline nasal irrigation after a positive COVID-19 PCR test were 19 times less likely to be hospitalized than the national rate.”
