Vitamin A increases cough incidence
We examined how vitamin A and zinc supplementation influences cough and other health issues in young children. In a carefully designed study involving 736 children in Mexico City, we found that vitamin A actually led to a 23% increase in cough with fever.
Surprisingly, while vitamin A raised rates of cough and diarrhea, zinc showed no impact on these conditions. Our findings suggest that vitamin A's effects can vary significantly depending on a child's living situation and household characteristics.

We explored how vitamin A could influence cough and other symptoms in ferrets infected with canine distemper virus (CDV). By comparing both vitamin A-replete and depleted ferrets, we found that those receiving high-dose vitamin A showed milder symptoms and recovered fully. It seems that vitamin A can enhance disease resistance, similar to its effects observed in children with measles. This suggests that improving vitamin A status might be beneficial during viral infections, particularly for respiratory symptoms like cough.

Vitamin A aids pediatric pneumonia recovery
We explored the effectiveness of Vitamin A as an added treatment for pediatric pneumonia, particularly focusing on its impact on coughing. By analyzing various studies through a systematic review, we found that incorporating Vitamin A can indeed lead to significant improvements in clinical symptoms for children suffering from this condition.
Our findings revealed that Vitamin A not only shortens hospital stays but also helps alleviate coughs that can be distressing for both children and their caregivers. This means that when combined with standard treatments, Vitamin A may help children recover faster by easing coughing and other respiratory symptoms.
Additionally, we discovered that Vitamin A has a favorable influence on inflammation levels in the body. Lower levels of certain inflammatory markers, like IL-6 and IL-10, were noted, which suggests that Vitamin A might contribute to reducing the severity of the illness.
Overall, we see Vitamin A as a promising option for improving the recovery of children with pneumonia, especially by easing cough symptoms, which is a significant concern for treating pediatric patients.

Cough relief achieved
4 people found this helpful
Stopped my cough of 20 years within 5 days of purchase. I had a chronic cough for two decades, visiting numerous doctors and undergoing countless tests, yet nothing helped. After reading an article suggesting 100,000 IU with 2 grams of crystallised Vitamin C three times daily, I decided to try it myself in addition to helping my husband recover from bronchitis. By the second dose, I had not coughed again. While it did return 50% after lowering the dosage, it was nothing like before. I appreciate purchasing it online as it is more affordable than health stores, though I remain slightly concerned about its toxicity.

We conducted a systematic review and meta-analysis of 15 trials to investigate if vitamin A effectively reduces cough in children with pneumonia.
The analysis included nearly 3,500 patients, comparing those receiving vitamin A alongside standard treatment to those who did not.
Our findings showed that vitamin A can aid in alleviating symptoms and shorten hospital stays, but it didn't significantly affect pneumonia-related mortality rates.

This study aimed to explore how vitamin A combined with iron impacts cough and infection rates in preschoolers.
By involving 445 children aged 3 to 6 in a well-structured trial, we found that those receiving both supplements showed the lowest incidence of respiratory illnesses, including cough, compared to those on just one supplement or none.
Significant benefits were observed over six months, indicating that vitamin A with iron could be beneficial for reducing infectious diseases in young kids.

Micronutrient fortification reduces cough
We focused on assessing whether adding a fortified seasoning powder to school lunches could improve children's health, particularly concerning cough and other illnesses.
In a randomized controlled trial involving 569 children, we found that the fortified seasoning reduced instances of cough by 20%. While this intervention didn't lead to significant changes in growth measures, it did help with reducing respiratory symptoms and improving visual recall. Overall, it reveals the potential benefits of micronutrient fortification in bolstering children's health.

Cured severe cough

This supplement effectively treated my severe throat cold. My throat mucous membrane was damaged, causing immediate coughing, but after taking it 2 to 3 times daily, I recovered within three days. For daily maintenance, 10,000 IU seems sufficient, but I had confusion after taking 27,000 IU regularly, even beyond the cold recovery period.

Reduced daytime cough

Taking Vitamin A has significantly aided my husband with severe asthma. I initially struggled to sleep, feeling suffocated, but after drinking 100,000 IU daily for about a month, it became much easier. Furthermore, my husband's daytime cough has decreased dramatically. It’s worth noting that high doses of vitamin A can lead to a deficiency in vitamin K, so incorporating natto in the diet is advisable.

Reduced asthma coughing
14 people found this helpful
Coming from a family with asthma and cancer, I realised a high dose of vitamin A is essential for me. I discovered that taking over 50,000 IU, along with a high-protein diet, helped reduce my reliance on inhalers. Notably, when I experienced severe coughing from asthma, high doses of vitamin A facilitated quicker recovery, and I intend to keep using it.

Vitamin A supports pneumonia treatment
We explored the role of vitamin A as an additional treatment for children with pneumonia. Analyzing 15 randomized controlled trials involving over 3,000 patients, we found that vitamin A supplementation improved clinical responses and shortened the duration of cough and fever.
While it didn’t reduce mortality rates, it effectively helped with other symptoms and reduced hospital stays. Importantly, there was no rise in side effects, making vitamin A a safe option to complement pneumonia treatment in young patients.

We examined how vitamin A levels influence cough and other health issues in school-age children. In a study of 2,774 kids in Bogotá, we found that those with low vitamin A levels experienced more coughs with fever and were generally sicker.
Specifically, lower vitamin A levels were tied to a 10% increase in days with cough compared to those with adequate vitamin A. However, the study highlights a need for further research to determine if vitamin A supplements can effectively reduce these health problems.

We analyzed randomized controlled trials to determine if vitamin A could prevent acute lower respiratory tract infections (LRTIs) in children up to seven years old.
Our findings showed that most studies reported no significant benefits of vitamin A for preventing cough or other LRTI symptoms. In fact, some studies indicated that vitamin A might even increase symptoms like cough and fever in certain children.
It appears that vitamin A may be beneficial only for those with low nutritional status, but it's not recommended for all children as a preventative measure against LRTIs.

We explored how vitamin A supplementation affects cough and diarrheal disease in young children from marginal communities in Mexico City. Our study included 188 children, who received either vitamin A or a placebo over 15 months.
While vitamin A did not significantly reduce overall diarrheal diseases, it did lower cases of mild watery diarrhea and cough with fever. Particularly, supplementation was more effective during the summer and among children with better nutritional status or socio-economic conditions.
However, the overall impact was varied, suggesting that vitamin A’s benefits may depend on different factors affecting each child.
