Vitamin A supports immune response
Effect of oral vitamin A supplementation on host immune response to infectious bronchitis virus infection in specific pathogen-free chicken.
Focus on viral immune response
We conducted a study to investigate how vitamin A supplementation affects the immune response in chickens infected with the infectious bronchitis virus (IBV). In our approach, we used 40 one-day-old specific pathogen-free (SPF) chickens, dividing them into two groups. One group received an oral vitamin A treatment daily, while the other group was given a placebo until they were 21 days old.
Afterward, both groups were infected with a pathogenic strain of IBV. Our findings showed that while vitamin A supplementation didn't significantly alter the disease's clinical course or the chickens' overall growth, it had some notable effects on their immune response. Specifically, we observed increased levels of IBV-specific antibodies and a decrease in viral load in certain tissues among the vitamin A group.
Interestingly, vitamin A appeared to also suppress some immune responses, leading to lower expression levels of certain molecules related to inflammation and immune regulation. While vitamin A helped improve specific aspects of the immune response, it did not completely cure the chickens or prevent infection.
Overall, we can conclude that while vitamin A supplementation can offer some benefits in terms of boosting immunity and managing viral replication, it doesn't drastically change the outcome of IBV infections in chickens.

Cough relief
This product resolved my chronic cough of 20 years within days. I bought it for my husband after his bronchitis, and it worked wonders for both of us. By the second dose, I stopped coughing entirely, which is something I hadn’t experienced before. This is now a staple in my home.

Phlegm decreased
The symptoms related to bronchitis have seen a significant reduction, as the phlegm that was being expelled from my bronchial tubes has subsided considerably.
