In total, we identified 12 trials, but only 10 provided sufficient data for analysis. Among healthy children from low-income communities, most studies did not show a clear benefit of zinc on reducing ear infections. However, one trial with over 1600 participants did find a significantly lower incidence of otitis media in those taking zinc, suggesting that it might help. Additionally, a small study focusing on infants with severe malnutrition hinted at potential benefits, yet it is important to note this was based on limited data.
Overall, the evidence isn't definitive—while some results point towards positive effects, particularly in specific groups, many trials did not support the effectiveness of zinc in healthy children. Furthermore, zinc supplements appeared safe, with minimal reports of adverse effects.
A total of 12 trials were evaluated, involving over 6,800 participants. While most studies, particularly those involving healthy children in low-income areas, showed no significant difference in the occurrence of ear infections between zinc and placebo groups, one trial did indicate a noteworthy reduction in the rate of otitis media among children receiving zinc supplements.
Additionally, a small trial involving infants suffering from severe malnutrition suggested that zinc may help decrease the number of ear infection episodes. However, the evidence remains mixed, especially for healthy children under five in lower income countries. In the end, while zinc supplements did not lead to serious side effects, some participants experienced mild vomiting after taking them.
Overall, while we found some positive indications for specific groups, the mixed results highlight the need for more research before concluding that zinc could be a reliable preventative measure against ear infections.
The results showed mixed outcomes, particularly among healthy children living in low-income communities. In two notable studies involving over 3,191 participants, there was no significant difference in the occurrence of OM between those who received zinc and those who were given a placebo. However, one trial with 1,621 children indicated that zinc did lower the rate of OM.
Furthermore, we looked into a smaller trial involving infants suffering from severe malnutrition, which suggested that zinc might help reduce the mean number of OM episodes. While zinc supplements didn’t appear to cause serious side effects, a few children did experience vomiting shortly after taking them.
Overall, the evidence regarding zinc's effectiveness in reducing ear infections, especially among young children in lower-income settings, remains mixed, and we must interpret these findings with caution, especially since the most promising results were from a small study.

The treatment involved the combination of Boswellia serrata, Bromelain, and other ingredients, including zinc, over 20 to 30 days. We used various methods, like otoscopy and auditory tests, to assess the children's health at the start of the study and after treatment.
Our results showed that both treatment groups performed better compared to the control group concerning measures like ear exams and hearing tests after treatment. However, while we observed improvements in the treatment groups, the specific impact of zinc alone could not be clearly determined given that it was part of a larger formula.
The findings highlight the potential of using this nutraceutical blend as a supportive therapy against upper respiratory infections in children, particularly with the inclusion of Boswellia and Bromelain for their anti-inflammatory properties. Nonetheless, we found it challenging to isolate zinc's individual benefit in this context.
We observed a significant reduction in the mean number of inflammatory episodes before and after the treatment— from 3 episodes down to just 1. Moreover, 77% of the children reported a noticeable improvement in the frequency of these episodes, showing that the treatment may positively influence their quality of life. The results were further supported by an improvement in a quality-of-life questionnaire, albeit with the acknowledgment that no isolated effect of zinc was highlighted since it were used with other herbal ingredients.
While our findings suggest that the herbal compound may help alleviate symptoms of recurrent ear infections, it's essential to note that the combined effect of zinc with other ingredients makes it challenging to measure its isolated impact. However, overall, we find that the herbal compound is a promising option for enhancing pediatric health without any reported side effects.
Over a three-month period, we observed that 50.8% of the children given the propolis and zinc suspension developed AOM, compared to 70.5% in the control group. This marked a significant reduction in infections, with the mean number of AOM episodes per child each month decreasing from 0.34 to 0.23.
The results suggest that administering a propolis and zinc solution can considerably lower the risk of new ear infections and the need for related antibiotic treatments, all while ensuring safety and a high rate of parental satisfaction. However, it is worth noting that the study does not imply any benefit of this treatment regarding other respiratory infections beyond AOM.
The group that received the immune-stimulating oral supplements, which featured zinc, was monitored for improvements in ear health through various measures, such as tympanometry and audiometry. While there was an overall positive trend among those who took the supplements, it’s essential to clarify that the isolated effect of zinc itself on ear infections was not fully determined in our findings.
We concluded that the supplements could enhance overall immune response and potentially reduce inflammation in the ear, thus aiding in better middle ear ventilation. However, the direct impact of zinc remains embedded within a combination of other treatments, making it challenging to specify its individual contribution to treating ear infections.

Frequently Asked Questions
An ear infection, also known as otitis media, occurs when germs—such as bacteria or viruses—infect the middle ear, which is the space behind the eardrum. This condition can cause a variety of symptoms, including ear pain, difficulty hearing, fluid drainage from the ear, fever, and irritability in children. Ear infections are particularly common in children due to their shorter and more horizontal Eustachian tubes, which make it easier for pathogens to reach the middle ear. When the Eustachian tubes become swollen or blocked due to upper respiratory infections, allergies, or sinus infections, fluid can accumulate and lead to an infection.
Treatment typically depends on the severity and frequency of the infections. For mild cases, doctors may recommend observation, as many ear infections resolve on their own. In more severe cases, particularly when symptoms last longer than 48 hours, antibiotics may be prescribed. Pain relievers can also help manage discomfort. In cases of recurrent infections, additional interventions, such as the placement of ear tubes, might be considered. Proper hygiene and avoiding exposure to smoke can also reduce the risk of developing ear infections.
Zinc is a versatile metal known for its various applications in industry and health. It is a bluish-white metallic element represented by the symbol Zn and atomic number 30 on the periodic table. Zinc is primarily used for galvanizing steel to prevent rusting, in the manufacturing of alloys, and as a component in batteries. Additionally, zinc plays a crucial role in biological processes, making it an essential trace element in the human diet. It is involved in immune function, protein synthesis, wound healing, and DNA synthesis, highlighting its importance in maintaining overall health and well-being.
While zinc is an essential mineral that plays a role in immune function, the evidence supporting its effectiveness specifically for treating ear infections is limited. Some studies suggest that zinc may help bolster the immune response, which could indirectly benefit those suffering from infections, but it should not be considered a primary treatment. Ear infections, particularly in children, often require antibiotics or appropriate medical intervention, so it's crucial to consult a healthcare provider for the best course of action.
Incorporating zinc-rich foods into your diet, such as meats, shellfish, legumes, nuts, seeds, and whole grains, can help support overall health. However, if you or someone you know is experiencing symptoms of an ear infection—such as pain, fever, or difficulty hearing—it's advisable to seek medical advice rather than relying solely on dietary supplements or minerals like zinc for treatment.
Based on user reviews, it seems that individuals taking zinc as a supplement for ear infections often report seeing results within a few days to a month of consistent use. For example, one user noted that after resuming zinc intake due to a sinus infection, they found it significantly bolstered their immune system, leading to no further sinus issues since starting again (Read Review). Another user mentioned experiencing a reduction in painful inflammation behind their ear just a few days after starting zinc (Read Review).
Additionally, a user reported noticeable improvement in their ear-related symptoms after taking zinc, indicating that the supplement may help with recovery from ear infections and related issues (Read Review). However, many users recommend taking it with food and maintaining a consistent dosage to optimize absorption and efficacy, often suggesting daily doses of around 50 mg (Read Review). Overall, while experiences may vary, many users agree that zinc can be beneficial in managing ear infections, with benefits often observable in a matter of days to weeks.
The current body of scientific research presents mixed findings regarding the effectiveness of zinc supplements in the treatment and prevention of ear infections, particularly otitis media. Multiple studies indicate that while zinc may contribute positively to overall immune health and potentially aid in inflammation reduction, the evidence does not conclusively support its isolated efficacy against ear infections. For instance, a study involving 198 children suggested that immune-stimulating oral supplements, including zinc, showed improved ear health trends, but the isolated effect of zinc was not definitively established [2]. Similarly, trials have found some positive results concerning the combination of zinc with other treatments but have struggled to isolate zinc's specific contributions [1], [3].
When evaluating zinc’s preventive potential, particularly in low-income populations, results remain inconsistent. A comprehensive analysis reviewed 12 trials and found that although some studies indicated a significant reduction in ear infection rates among children receiving zinc, the overall perspective remained cautious due to mixed outcomes, especially in healthy children [5], [8]. Collectively, these findings suggest that while zinc may have a supportive role in ear health, particularly in conjunction with other therapies, further rigorous research is needed to clarify its efficacy as a standalone treatment or preventive measure for ear infections.
Users have reported a variety of improvements in their symptoms after taking zinc supplements, with experiences varying from enhanced immune function to aesthetic benefits. For instance, one user noted a restoration of their sense of smell following an ear infection, as well as improvements in hair, skin, and nail health after one month of consistent zinc use (Read Review). Other reviewers remarked on zinc's effectiveness in reducing symptoms of colds and infections, citing a notable decrease in illnesses within their families during peak cold seasons (Read Review). Additionally, one user experienced a significant reduction in painful inflammation behind their ear just days after starting zinc, suggesting its anti-inflammatory properties (Read Review).
Many users appreciate zinc's role in overall health maintenance, citing its benefits during viral outbreaks and its contribution to combating infections (Read Review). However, it's important to note that experiences may vary; while some users reported swift improvements, others like the reviewer who took zinc for migraines found that while it didn’t shorten their cold, it significantly decreased the frequency and intensity of their migraines (Read Review). Overall, many users advocate for the supplement's immune-boosting capabilities and its supportive role in recovery from infections.
According to user reviews, many individuals who combine zinc with other supplements, particularly Vitamin C, report significant benefits in combating infections, including ear infections. One user specifically mentioned taking zinc alongside Ester C to prevent becoming ill, noting that both he and his son experienced impressive improvements in their health after doing so (Read Review). Another reviewer highlighted the synergistic effect of zinc with Vitamin C during cold onset, reinforcing the idea that these supplements can enhance each other's effectiveness (Read Review).
Additionally, some users advocate for careful timing in supplement intake. One user took zinc at different times from other minerals for better absorption, reflecting a preference for optimizing the benefits rather than taking all supplements simultaneously (Read Review). Overall, many reviewers encourage the combination of zinc with other supportive nutrients to bolster immunity and aid in recovery from infections like ear infections, indicating that the right combinations can yield notably positive results.
Users report varying dosages of zinc for treating ear infections, with a common recommendation of 50 mg daily. For instance, one user shared that they took 50 mg per day for a month after an ear infection, emphasizing its role in restoring the sense of smell and boosting immunity against infections (Read Review). Similarly, another user mentioned taking zinc as part of their regimen during cold and flu seasons, suggesting that increased doses helped them recover faster from ear infections and other health issues (Read Review).
Reviewers noted that while higher doses, particularly during periods of illness, showed promising results, a careful approach is recommended. Some users mentioned that they experienced fewer side effects and improved health by possibly adjusting their zinc intake around their meals or in conjunction with other vitamins (Read Review). Collectively, these reviews indicate that while zinc can be a beneficial supplement for ear infections and immunity, users should personalize their dosage based on their specific health needs and circumstances.
