We investigated the effectiveness of zinc sulphate in treating acute bronchiolitis in children, aiming to uncover whether this supplement could help speed recovery. In our study, we closely examined 100 young patients diagnosed with the condition. Half of the children received oral zinc sulphate while the other half received a placebo.
Over the course of the treatment, we compared the clinical signs and symptoms between the two groups at several intervals: 24, 48, 72, 96, and 120 hours after starting. Encouragingly, we observed that those in the zinc group showed a more favorable trend in recovery compared to the placebo group across all time points. Notably, significant differences were noted in improvements of coughing and wheezing at the 48 and 72-hour marks.
Remarkably, we found that 98% of the children who received zinc sulphate achieved full recovery within 72 hours of treatment—indicating a rapid response to the therapy. Our findings suggest that zinc sulphate can notably accelerate the improvement of clinical symptoms in acute bronchiolitis. Therefore, we feel confident recommending zinc sulphate as a helpful treatment option for this condition.

Vitamin C aids bronchitis resistance
We explored how supplementing the diet of broiler chicks with different levels of vitamin C, also known as ascorbic acid, impacts their resistance to infectious bronchitis virus. The goal was to determine whether this supplement could help improve their health by measuring the severity of tracheal lesions and the presence of airsacculitis after exposure to the virus.
Our findings indicated that the effectiveness of vitamin C was dose-dependent. We observed that adding between 300 to 330 parts per million (ppm) of ascorbic acid to their feed yielded the best protective results. Interestingly, when we looked at higher concentrations—beyond 600 ppm—the benefits seemed to diminish. This suggests that while vitamin C can be beneficial, there's a suitable range for its effectiveness.
Overall, this study highlights the potential of vitamin C as a useful dietary addition for enhancing the health of broilers facing bronchitis. Yet, it's clear that more isn't always better when it comes to dosage, and finding that sweet spot is crucial for maximizing its effectiveness.

We conducted a thorough investigation into how vitamin C supplementation impacts elderly patients hospitalized with acute respiratory infections, specifically bronchitis and bronchopneumonia. In our study, 57 patients participated in a randomly assigned, double-blind trial where they received either 200 mg of vitamin C daily or a placebo.
The results were promising, revealing that this modest vitamin C dose significantly raised the levels of vitamin C in both the plasma and white blood cells, even during an acute respiratory infection. Our clinical scoring system, which monitored major respiratory symptoms, showed that those who received vitamin C reported better outcomes compared to those who took the placebo.
This effect was especially notable among the patients who were the most severely ill at the start of the trial. Many of these individuals had low vitamin C levels upon admission, yet they showed improvement after supplementation. We also discussed various mechanisms through which vitamin C may benefit these patients, highlighting its potential role in supporting recovery.

Rapid recovery experienced
I want to share my impressions of these pastilles. I was sceptical about immunity pills. Having chronic tonsillitis, I frequently fell ill. After taking these vitamins, my husband and child both fell ill. I gave them the lozenges—my husband recovered in a week, my child bounced back in 2 days, and I remained healthy, which was surprising. Highly recommend!

We explored the effects of zinc, combined with thymic hormones, on immunization against bronchitis in vaccinated chickens. In a detailed study, chickens were given a trivalent killed vaccine that protected against infectious bronchitis, bursal disease, and Newcastle disease. They were split into groups, receiving various combinations of zinc and thymic hormones to see how it influenced their immune response.
We observed that most of the vaccinated groups experienced significant improvements in immunity when treated with zinc alongside thymic hormones. Particularly, the combination of thymulin and zinc led to remarkable increases in antibodies against the viruses—showing increases of up to 671.7%. This suggests that zinc can play a crucial role in enhancing the immune response following vaccination, notably against bronchitis.
Additionally, we noted the strongest cell-mediated immunity in those treated with a mix of both thymic hormones and zinc. This means that zinc not only helps boost antibodies but might also enhance the overall immune activity against infections, including bronchitis.

We investigated how dietary factors, particularly vitamin C, might influence the occurrence of bronchitis symptoms. Drawing insights from the Second National Health and Nutrition Examination Survey, which included a diverse group of adults aged 30 and older, we analyzed data on participants' dietary habits and their reported respiratory symptoms.
Our focus was on the link between vitamin C levels and bronchitis. We found that higher serum levels of vitamin C were negatively associated with bronchitis symptoms, suggesting that individuals with greater vitamin C levels were less likely to experience bronchitis. This connection remained significant even when factoring in age, race, gender, and smoking history.
Additionally, we noted the importance of the ratio of zinc to copper in the blood and how dietary sodium and potassium intake also played roles in respiratory health. Our findings indicate that a diet rich in vitamin C and certain minerals may help protect against bronchitis, independent of smoking habits. Ultimately, proper nutrition could be a simple yet effective way to support respiratory health in adults.

We investigated the effectiveness of vitamin C compared to azithromycin in treating acute bronchitis through a controlled trial. This study included adults without underlying lung conditions who were randomly assigned either azithromycin or vitamin C for five days.
After a week, we assessed health-related quality of life improvements among the participants. The results were clear—there was no significant difference in recovery between those taking azithromycin and those taking vitamin C.
In fact, 89% of both groups reported returning to their usual activities after seven days, indicating that neither treatment offered a notable advantage. Interestingly, most participants found benefit from an albuterol inhaler, which suggests that supportive care might play a crucial role in their recovery.
Ultimately, our findings show that low-dose vitamin C is no better than azithromycin for dealing with acute bronchitis, highlighting the need for future research to better identify effective treatments for this condition.

Vitamin C potentially aids bronchitis
We explored how vitamin C might play a role in managing bronchitis, particularly in relation to the harmful effects of air pollution. The study investigated the mechanisms through which vitamin C can protect lung health, especially against oxidative damage caused by pollutants like NO2 and O3.
Our findings indicated that vitamin C effectively prevents lung lipids from oxidation by these harmful substances. Interestingly, studies on both human cells and experimental animals demonstrated that this vitamin can offer substantial protection against oxidative stress linked to tobacco smoke and environmental pollutants.
We also observed that vitamin C levels in the lungs can either decline with short-term exposure to NO2 or increase with chronic exposure to cigarette smoke. This might suggest that maintaining adequate vitamin C levels could be crucial for lung health, particularly for individuals exposed to high pollution levels.
While our review highlighted the benefits of vitamin C supplementation, especially at higher doses than normally recommended, it’s clear that more research is needed. Current guidelines may not provide enough protection for the populations heavily affected by air pollution.
Overall, while vitamin C appears promising in helping manage lung conditions like bronchitis, its effectiveness in preventing or treating such diseases still requires further exploration.
