Zinc accelerates bronchiolitis recovery
Zinc sulphate for acute bronchiolitis: A double-blind placebo-controlled trial.
Direct focus on zinc's effectiveness
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
Ascorbic acid and infectious bronchitis infections in broilers.
Highly relevant to vitamin C study
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.

Vitamin C aids bronchitis recovery
The clinical effects of vitamin C supplementation in elderly hospitalised patients with acute respiratory infections.
Highly relevant to research question
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!

Mom healed quickly
I bought this for my mother, who often suffers from ARVI, tonsillitis, and bronchitis. She was sceptical about such supplements. After taking it, alongside probiotics for her throat, she recovered in just 10 days, rather than her usual month-long illness. I was thrilled, though she still wishes it was coincidence! I'll definitely buy this wonderful set again!

Family saved
These lozenges are excellent for the first sign of a cold or sore throat. Though I had initial doubts due to the low price, our family has seen that the combination of elderberry, vitamin C, and zinc works wonders! Improvements were noticeable almost on the second day. This supplement is a lifesaver during cold and virus season, allowing our family to avoid persistent bronchitis.

Zinc enhances bronchitis immunity
Humoral and cell-mediated immunopotentiation in vaccinated chicken layers by thymic hormones and zinc.
Significant findings on zinc impact
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.

Vitamin C may alleviate bronchitis
Dietary factors and their relation to respiratory symptoms. The Second National Health and Nutrition Examination Survey.
Significant relationship identified
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.

Faster recovery noted
I stumbled upon this zinc supplement, which also contains vitamin C—ideal for immunity. The quality is excellent with a pleasant taste. I take it at the onset of a cold, and I recover faster, experiencing fewer incidences of bronchitis that previously required antibiotics.
