We investigated the impact of dispersible zinc tablets on postoperative sore throat (POST) experienced by patients after endotracheal intubation. In our study, 88 patients were divided into two groups. One group received a 40 mg zinc tablet, while the other received a placebo 30 minutes before their surgery.
Our findings revealed that the zinc group reported significantly fewer instances of POST at the 4-hour mark compared to the placebo group. Specifically, only 6.8% of patients in the zinc group experienced POST, while a higher 31.8% in the placebo group did. Furthermore, none of the patients taking zinc reported severe sore throat, a stark contrast to three patients in the placebo group who did.
Additionally, we noted lower severity ratings for sore throat in the zinc group at various time intervals post-surgery. The results emphasize that taking zinc tablets before surgery can effectively mitigate the incidence and discomfort of sore throat following intubation, presenting a simple solution for a common postoperative issue.

We explored the potential benefits of zinc lozenges for easing postoperative sore throat (POST), a common discomfort following endotracheal intubation. By conducting a randomized, double-blinded trial with 79 patients undergoing low- to moderate-risk surgeries, we divided participants into two groups: one received zinc lozenges, while the other was given a placebo.
Our findings revealed promising results. At the crucial four-hour mark post-surgery, only 7% of patients who took zinc experienced POST, compared to 29% in the placebo group. Interestingly, the difference was even more pronounced right after surgery, where the zinc group reported a 0% incidence of POST versus 24% for the control group.
Moreover, the severity of sore throat symptoms was notably less intense among those in the zinc group. Those with mild and moderate sore throat pains reported significantly lower severity scores. These results suggest that a single dose of 40 mg of zinc lozenges taken just 30 minutes before surgery can greatly aid in reducing both the occurrence and discomfort of POST in the early hours after surgery.

Zinc reduces postoperative sore throat
We conducted a study to understand how well zinc can help prevent postoperative sore throat (POST) after endotracheal intubation. We compared the effects of gargling with zinc sulphate versus magnesium sulphate in a controlled trial involving 132 patients. Those in the zinc group received a solution with 40 mg of elemental zinc, while the magnesium group used 20 mg/kg of magnesium sulphate, with a control group receiving only dextrose.
Our findings showed that the group using zinc sulphate experienced notably lower rates of sore throat compared to those using magnesium sulphate. Specifically, the incidence of mild POST was significantly lower in the zinc group, especially during the first four hours after surgery. Overall, zinc gargle proved to be more effective in reducing sore throat compared to magnesium sulphate, demonstrating its potential benefits in postoperative care.
These results highlight the importance of zinc as a simple yet effective intervention to reduce discomfort for patients following surgery. By using zinc gargle preoperatively, we can potentially improve patient outcomes related to postoperative sore throat.

The best zinc on iHerb! Excellent, high-quality zinc in a small dosage (15 mg in one capsule), well absorbed, and does not cause nausea. Zinc is vital for immunity, especially during a pandemic! Taking 3-4 capsules at the initial stage of sore throat helps stop the disease's progression. I have tested this repeatedly on myself and loved ones. A course of zinc has improved my hair, skin, and nails. I highly recommend this particular product, it is really the best on iHerb!

Very effective product
Great quality zinc with 15 mg taken twice daily works wonders for me. I noticed its impressive effectiveness against viral infections; I experienced only a sore throat for less than 48 hours when I caught Covid. There’s no unpleasant aftertaste, making it an essential mineral for a robust immune system.

Zinc's role in sore throat treatment
We evaluated a promising dietary supplement that combines honey, propolis, and zinc to see how effective it could be for children suffering from acute tonsillopharyngitis, a type of sore throat. In this open-label, randomized, and controlled study, we compared the supplement along with standard care against standard care alone over six days.
The results revealed that incorporating the supplement with standard care led to notable improvements in certain symptoms associated with sore throat, such as throat pain and swallowing difficulties by day four and six. Although zinc was part of the blend, it was challenging to pinpoint its independent effect, given that it was studied alongside honey and propolis.
Interestingly, only one child in the standard care group needed additional medications like ibuprofen, highlighting that the supplement may reduce the need for further treatment. Importantly, we did not report any adverse events, making this combination a potential safe addition to treatment.
Overall, while the study presents encouraging results regarding the adjunctive use of the supplement in treating sore throat, it remains unclear how much zinc alone contributes to its effectiveness.

We examined recent findings regarding zinc's impact on sore throat, particularly in post-operative settings. Some studies have reported that specific zinc formulations, like polaprezinc, can effectively reduce symptoms associated with sore throat after procedures like endotracheal intubation.
Importantly, zinc sulfate showed mixed results, with one review suggesting it did not significantly decrease the occurrence or intensity of oral mucositis in cancer patients. However, there are indications that certain zinc preparations may still hold promise in specific contexts, such as managing sore throat post-surgery.
Overall, while zinc's benefits in sore throat treatment appear to vary, ongoing research explores the best applications and formulations of zinc to potentially ease discomfort. As such, individuals seeking relief should keep an eye on emerging studies that could clarify zinc's role in throat health.

Reduced symptoms time
Recently, I caught a cold with a runny nose and sore throat. I tried zinc along with my regular vitamin C. While unsure of its influence, my sore throat and nasal discomfort lasted only 5 days instead of 7. The capsules were comfortable to take, twice daily as advised.

We conducted a rigorous study to see how zinc acetate lozenges might help reduce the painful and annoying symptoms of the common cold, particularly sore throats. In a well-structured environment, we recruited 50 volunteers who started experiencing cold symptoms within the last 24 hours. Participants were randomly assigned to receive either zinc lozenges or a placebo, taking one every few hours during the day.
Over the course of the study, we monitored various symptoms, including sore throat, and measured participants' plasma zinc and cytokine levels on the first day and as they recovered. We observed that those who took zinc lozenges experienced a shorter duration of cold symptoms, with cough showing notable improvement.
However, when it came to sore throats specifically, while there were positive results, the changes didn't stand out as significantly different from those who received the placebo. So, while zinc may play a role in easing cold symptoms overall, its particular impact on sore throat isn’t conclusively proven in our findings.
