Zinc effective for acne treatment
Serum zinc levels and efficacy of zinc treatment in acne vulgaris: A systematic review and meta-analysis.
Most Relevant Research
We explored how zinc affects acne through a systematic review and meta-analysis that looked at two main questions. First, we wanted to know if there are differences in zinc levels between people with acne and those without. Second, we examined how effective zinc treatments are for managing acne.
Our findings showed that individuals with acne had noticeably lower serum zinc levels compared to those in the control group. Furthermore, when we looked at treatments, those who received zinc showed a significant reduction in their inflammatory papule count—a common symptom of acne. Importantly, we noted that side effects from zinc supplementation were similar to those seen in other treatments, suggesting that zinc is safe to use.
Overall, acne patients appear to benefit from improved zinc levels, especially when zinc is used either on its own or alongside other acne treatments. This gives hope for those looking for effective ways to tackle acne issues!

Zinc may relieve allergy symptoms
Alleviating effect of intranasal zinc on symptoms of allergic rhinitis.
Most Relevant Research
We investigated how intranasal zinc (Zn) treatment affects symptoms of allergic rhinitis (AR), specifically focusing on individuals suffering from Japanese cedar pollinosis (JCP), a common seasonal allergy. In our study, we monitored 57 control subjects and 44 patients from preseason through the allergy season, observing the levels of Zn in both nasal fluid and serum.
Our findings showed that after exposure to pollen, the level of zinc in the nasal lining fluid of JCP patients significantly increased, while their serum zinc levels notably decreased compared to the control group during the JCP season. To delve deeper, we used model mice that could mimic these changes and the allergy symptoms of the patients.
The results from this mouse study were promising. We observed that treating these mice with a dose of zinc, similar to what humans might use, led to a notable improvement in their allergy symptoms. Additionally, the number of mucin-secreting goblet cells, which indicate a response to allergies, significantly decreased following the zinc treatment.
Our study points towards the potential of using intranasal zinc as a way to alleviate allergy symptoms, suggesting a new approach to managing allergic rhinitis.

Zinc enhances blood clot formation
Enhanced coagulation cascade activation and styptic effects of Zn@SiO nanocomposite.
Most Relevant Research
We explored how zinc affects blood clotting, particularly through a substance called Zn@SiO nanocomposite. This material shows promise as a hemostatic agent, which means it helps stop bleeding by promoting the formation of stable blood clots.
During our analysis, we examined various aspects of how this nanocomposite interacts with blood. It activates specific factors in the coagulation cascade—the process our bodies use to form clots. With the presence of zinc in the material, we observed enhanced activation of these factors, leading to improved clot formation.
Our research involved synthesizing and characterizing the Zn@SiO nanocomposite using several methods, including XRD, FTIR, and HRTEM. We also tested its effects on red blood cell aggregation, platelet adhesion, and several vital clotting time measures. The results indicate that Zn@SiO has significant hemostatic properties, showing potential for use in surgeries and trauma care.
This study highlights the exciting role of zinc in optimizing hemostasis, making it a candidate worth considering for medical applications related to bleeding management.

Most Useful Review
This dietary supplement contains zinc gluconate, which has a 60% digestibility rate, making it preferable since zinc can be difficult to absorb. For instance, zinc oxide might not be absorbed at all. Therefore, when purchasing dietary supplements with zinc, it's essential to check the type of zinc used; otherwise, you may end up with ineffective products. Since taking zinc, I've noticed a slight reduction in the fat content of my facial skin and scalp. I feel more cheerful overall, and it seems that my brain activity, memory, and concentration have improved significantly.

Zinc supplementation may benefit CFS
Lower serum zinc in Chronic Fatigue Syndrome (CFS): relationships to immune dysfunctions and relevance for the oxidative stress status in CFS.
Most Relevant Research
We explored the relationship between serum zinc levels and chronic fatigue syndrome (CFS) in a study that compared patients with CFS to normal volunteers. By using an atomic absorption method, we measured serum zinc concentrations and found that those suffering from CFS had significantly lower levels of zinc compared to healthy individuals.
Interestingly, we observed a trend indicating that lower zinc levels correlated with greater CFS severity. Patients also reported a negative correlation between their zinc levels and their subjective experiences of infection. This suggests that zinc plays a role in the immune dysfunction commonly seen in CFS.
Furthermore, we noted that lower serum zinc was associated with higher levels of inflammatory markers and certain defects in the early activation of T cells. Since zinc acts as a potent antioxidant, our findings indicate that CFS is linked to increased oxidative stress in these patients. Given this, it may be beneficial for some CFS patients to consider zinc supplements as part of their treatment approach.

Zinc shortens cold duration variability
Quantile Treatment Effect of Zinc Lozenges on Common Cold Duration: A Novel Approach to Analyze the Effect of Treatment on Illness Duration.
Most Relevant Research
We explored how zinc lozenges affect the duration of the common cold through a detailed analysis of multiple trials. In particular, we focused on the Mossad (1996) trial involving zinc gluconate lozenges, which revealed an average reduction of cold duration by about 4.0 days. While that sounds promising, our findings through a quantile treatment effect (QTE) analysis tell a more nuanced story.
Interestingly, the QTE analysis showed that for individuals suffering from lengthy colds lasting 15 to 17 days, the zinc lozenges could shorten their illness by as much as 8 days. On the flip side, those with shorter, 2-day colds only experienced a 1-day reduction in sickness. This suggests that while zinc may help, its effectiveness varies significantly depending on the initial duration of the cold, making the overall average effect less informative than we might think.
Our examination extended to three trials that used zinc acetate lozenges, yielding a similar average reduction of around 2.7 days. However, again, those averages concealed varying effects for short and long colds, highlighting the importance of looking beyond simple averages in treatment studies.
Overall, we observed that zinc lozenges can indeed help with cold duration, but the extent of that help is very much dependent on how long a person has been suffering. This approach to understanding treatment effects through QTE analysis could have important implications not just for cold treatment but also for analyzing other health outcomes.

Zinc promotes sleep in mice
Zinc-containing yeast extract promotes nonrapid eye movement sleep in mice.
Most Relevant Research
We explored the effects of zinc on sleep by looking at how it might help with insomnia. In our study, we gave mice a zinc-containing yeast extract and monitored their behavior and brain activity. The results were quite promising.
We found that administering zinc at doses of 40 and 80 mg/kg led to a significant increase in non-rapid eye movement (NREM) sleep. This means that the mice were not only sleeping longer but also showed less activity, which is a good indicator of effective sleep. Interestingly, we did not observe any changes in rapid eye movement (REM) sleep, a crucial sleep phase for dreaming and deep rest.
Importantly, we didn’t see any negative side effects, such as rebound insomnia, within 24 hours after treating the mice. This suggests that zinc could be a safe option for those struggling with sleep issues, unlike other mineral extracts we tested, such as manganese, iron, and copper, which did not affect locomotor activity at all.
Overall, our findings provide the first evidence that zinc has a direct role in promoting sleep, opening up exciting possibilities for new sleep supplements featuring this essential mineral.

Zinc's complex role in prostate cancer
Prostate cancer-selective anticancer action of an oxindole derivative via HO-1-mediated disruption of metabolic reprogramming.
Most Relevant Research
We explored the relationship between zinc levels and prostate cancer treatments, particularly focusing on a novel compound known as 3D. This compound showed a strong potential to target prostate cancer cells, contributing to a decrease in their proliferation rates.
Our analysis revealed that compound 3D selectively impacted key metabolic processes in prostate cancer cells by suppressing factors related to energy production, such as lactate levels. Interestingly, it also reduced the activity of transporters involved in zinc absorption while leaving those responsible for zinc export untouched.
We also found that the effectiveness of 3D could be reversed with zinc treatment, highlighting a complicated interaction between zinc and this therapeutic approach. While the compound successfully lowered zinc levels in cells and inhibited cancer growth, it is essential to note that we did not find significant benefits from zinc treatment by itself in the context of this study.
Overall, our findings suggest that targeting zinc metabolism and enhancing heme oxygenase-1 expression could be a promising strategy in prostate cancer therapy, more so than the direct application of zinc itself. The results illustrate the potential for combining innovative small molecules with an understanding of cancer metabolism in the development of treatment strategies.

Zinc protects heart function in OSA
Zinc Is Indispensable in Exercise-Induced Cardioprotection against Intermittent Hypoxia-Induced Left Ventricular Function Impairment in Rats.
Most Relevant Research
We explored how zinc affects heart function in the context of obstructive sleep apnea (OSA), specifically focusing on cases of intermittent hypoxia (IH). In a detailed study using male rats, researchers set up different groups: a control group and one that underwent 10 weeks of exercise training. Half of the rats in both groups were exposed to IH conditions to simulate the effects of sleep apnea.
The results were eye-opening. Rats that experienced IH showed notable impairment in their heart's left ventricular function, characterized by reduced ejection fraction and increased inflammation. However, when treated with zinc, these negative effects were significantly countered. Notably, those who exercised and received zinc treatment displayed improved heart function and antioxidant capabilities compared to their counterparts that did not receive zinc.
On the flip side, exercise alone did not provide the same protective benefits when zinc was absent. The findings suggest that zinc is essential not only for the heart's protection against the damaging effects of IH but also enhances the benefits of physical exercise. This research indicates the importance of zinc in potentially managing heart health in individuals suffering from sleep apnea.

New treatment reduces digital dermatitis
Investigation on the effectiveness of a new hoof care product to sustainably reduce and prevent digital dermatitis in dairy cow herds.
Most Relevant Research
We embarked on an investigation to understand whether a new hoof care product featuring iron, zinc, and aluminum can effectively reduce and prevent digital dermatitis (DD) in dairy cows. In a controlled trial involving over 130 dairy cows, we treated one hind foot of each cow twice a week with this product while leaving the other foot untreated for comparison.
The results were revealing! Our analysis indicated that the use of the hoof care product significantly reduced the severity of DD compared to the untreated group. In fact, cows treated with the product had a much lower chance of developing lesions. The outcome showed that in the control group, the odds of having a lesion were four times higher than in the treated group, and the likelihood of experiencing an active lesion versus an inactive one was even more pronounced.
Interestingly, we also observed positive outcomes in heifers, with only one developing an active lesion in the treated group, showcasing the potential for this product to help manage and prevent DD even before these young cows enter the herd. The study indicates that the combination of ingredients in this hoof care product could be a promising alternative to traditional, harsher treatments.
While zinc is included as one of the components in the product, it's essential to note that we can't isolate its effect on ulcers from the other ingredients. Therefore, we can't definitively conclude zinc's sole effectiveness when it comes to DD treatment, but the overall findings are encouraging for improving hoof health in dairy cows.

Zinc’s effects on colds
Zinc for prevention and treatment of the common cold: Summary of a Cochrane review.
Most Relevant Research
We explored how zinc might help in treating and preventing the common cold. The study focused on zinc's effects, isolating it from other treatments to understand its true impact on cold symptoms. By doing this, the researchers aimed to clarify whether zinc could genuinely shorten the duration of a cold or alleviate its symptoms.
The findings were intriguing but showed that zinc might not yield significant benefits for everyone. While some individuals reported a slight reduction in cold symptoms, the evidence did not strongly support zinc as an effective treatment overall.
This means that, for those seeking relief from a nasty cold, zinc alone might not be the go-to solution we hoped it would be. It’s essential to consider this information when deciding on a cold treatment plan and to approach zinc with realistic expectations.

Zinc treatment impacts flu virus entry
Epipharyngeal Abrasive Therapy Down-regulates the Expression of Cav1.2: A Key Molecule in Influenza Virus Entry.
Most Relevant Research
In our study, we examined how epipharyngeal abrasive therapy (EAT), which includes the use of zinc chloride, affects the expression of a key molecule known as Cav1.2. This molecule is essential for the influenza virus to enter cells, making it a crucial target in flu prevention strategies.
We compared two groups of patients: those who received EAT and those who did not. Our findings revealed that the levels of Cav1.2 were significantly lower in the EAT group, at a striking 4.19 times less than in the non-treated group. This suggests that the squamous metaplasia induced by EAT—which is a process of changing the epithelium—could be a beneficial approach to limiting flu infections.
The results of the study highlight zinc's potential indirect role in flu prevention by remarking on its contribution to lowering the expression of a critical receptor for the virus. Although we didn't isolate the effects of zinc alone, the findings indicate that treatments involving zinc, like EAT, may offer a straightforward way to help limit the impact of influenza.

Zinc enhances eczema recovery
Transient symptomatic zinc deficiency in an exclusively breastfed infant.
Most Relevant Research
We investigated the relationship between zinc deficiency and eczema in a 3-month-old infant who was exclusively breastfed. The infant presented with symptoms like scaling erythematous dermatitis affecting her face and other areas, alongside irritability and poor weight gain. Her mother had been taking isoniazid for tuberculosis during pregnancy, which possibly contributed to the infant’s zinc deficiency.
After initial treatments for a suspected skin infection didn’t bring any changes, we found that the baby had low serum zinc levels and low zinc concentration in her breast milk. This led us to believe the skin condition was due to zinc deficiency rather than an infection. We started zinc supplementation, and the infant showed remarkable improvement in her skin condition and weight.
By 6 months, the infant had begun eating solid food, and we stopped the zinc supplements, with no signs of eczema returning. This case underscores the importance of monitoring zinc levels in breastfed infants, especially when mothers are on specific medications that might impact nutrient transfer through breast milk.

Zinc reduces migraine symptoms
Assessing the Effect of Zinc Supplementation on the Frequency of Migraine Attack, Duration, Severity, Lipid Profile and hs-CRP in Adult Women.
Most Relevant Research
We conducted a randomized, double-blind, placebo-controlled trial to explore how zinc gluconate affects migraine symptoms in women. Sixty participants, with an average age of 35, were given either 15 mg of zinc per day or a placebo for 12 weeks, allowing us to measure the impact on headache frequency, duration, and intensity.
The results were quite promising; zinc supplementation significantly reduced how often headaches occurred, shortened their duration, and decreased the severity of the migraines reported. Participants in the zinc group experienced notable improvements, as indicated by their responses to the headache severity scale and a disability assessment questionnaire.
Furthermore, we found that zinc also had a positive effect on certain health markers. The serum levels of low-density lipoprotein (LDL), total cholesterol, and high-sensitivity C-reactive protein (hs-CRP) decreased with zinc supplementation.

Zinc improves cholesterol levels
Effect of Zinc Supplementation on Lipid Profile and Body Composition in Patients with Type 2 Diabetes Mellitus: A GRADE-Assessed Systematic Review and Dose-Response Meta-analysis.
Most Relevant Research
We explored how zinc supplementation affects cholesterol levels and body composition in patients with type 2 diabetes. By reviewing data from nineteen randomized controlled trials, involving 1,357 participants, we uncovered significant findings regarding lipid profiles.
Our results revealed that zinc supplementation leads to reduced levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol (LDL-C). Specifically, we noted reductions of 17.41 mg/dL in triglycerides, 19.60 mg/dL in total cholesterol, and 8.80 mg/dL in LDL-C. Furthermore, we observed an increase in high-density lipoprotein cholesterol (HDL-C) by 4.82 mg/dL, which is often termed "good" cholesterol.
While zinc appears to positively influence cholesterol levels, it's interesting to note that it did not have a significant impact on body weight. The body mass index (BMI) did show a slight decrease of 0.53 kg/m², but overall body weight remained unchanged.
In conclusion, our findings suggest that zinc supplementation could be a beneficial strategy for improving cholesterol levels in individuals with type 2 diabetes, thus contributing positively to their overall health and well-being.

Zinc's uncertain role in hypothyroidism
The Effect of Some Micronutrients Multi-Supplementation on Thyroid Function, Metabolic Features and Quality of Life in Patients Treating With Levothyroxine and Vitamin D: A Double-blind, Randomized Controlled Trial.
Most Relevant Research
We conducted a study to investigate the effects of micronutrient supplementation, including zinc, on thyroid function and overall quality of life in patients with hypothyroidism. Our trial involved 104 participants who were receiving levothyroxine and vitamin D. They were randomly assigned to either a group that received a mix of essential nutrients or a placebo group over eight weeks.
We measured various health markers before and after this period, including thyroid hormone levels, cholesterol, insulin resistance, and blood pressure. Our findings suggested that the group receiving the micronutrient supplement experienced improvements in insulin resistance and overall quality of life. However, it’s important to note that the specific effects of zinc alone are somewhat difficult to isolate, as it was part of a combination of nutrients being tested.
Ultimately, while the study indicates potential benefits of micronutrient supplementation for thyroid function in hypothyroid patients, further trials are necessary to clearly define the role of zinc and other nutrients in this context.

Zinc intake may protect bones
The association between dietary zinc intake and osteopenia, osteoporosis in patients with rheumatoid arthritis.
Most Relevant Research
We investigated the connection between dietary zinc intake and the prevalence of osteoporosis and osteopenia in patients with rheumatoid arthritis (RA). Using data from the National Health and Nutrition Examination Survey collected over several years, we applied various statistical methods to analyze how zinc impacts bone health in these patients.
Our findings revealed that higher dietary zinc intake appears to be linked with a lower incidence of osteopenia and osteoporosis among individuals with RA. This suggests that consuming adequate amounts of zinc might support better bone health for those suffering from this chronic condition.
Despite our positive findings, we acknowledge that further research, including longitudinal and randomized trials, is essential for confirming these results and understanding the underlying mechanisms at play. However, the evidence from our analysis encourages a focus on dietary zinc as a possible factor in maintaining bone health for patients with RA.

Zinc's role in cancer immunity
cancer cells outcompete macrophages for microenvironmental zinc to drive immunotherapy resistance.
Most Relevant Research
We explored how zinc levels impact cancer cells and immune function, particularly focusing on macrophages, which are crucial for our body’s defense against tumors. Our research revealed that cancer cells often have decreased expression of specific genes tied to immune response, and this links to resistance against therapies designed to unblock immune checkpoints.
By upregulating a zinc importer known as SLC39A9, these cancer cells manage to hoard zinc for themselves, leaving the surrounding tumor microenvironment (TME) depleted of this vital nutrient. This competition for zinc results in macrophages becoming zinc-starved, which diminishes their ability to perform essential tasks like engulfing and destroying cancer cells.
Interestingly, we found that when we replenished zinc levels in the TME—through a dietary intervention—these macrophages could regain their pro-phagocytic function. This change significantly improved the response of certain tumors to immunotherapy treatments. Notably, T cells weren’t required for this transformation, indicating that macrophages alone play a pivotal role.
Our results are clinically relevant, showing that cancer patients with reduced zinc levels in their body tend to experience worse outcomes. Overall, we identified a new mechanism by which cancer cells can disrupt immune function, highlighting zinc’s critical role in both tumor environments and immunotherapy effectiveness.

Zinc may boost bone density
Treatment for osteoporosis in people with beta-thalassaemia.
Most Relevant Research
We explored how zinc supplementation might help with back pain in individuals with beta-thalassaemia. The research included a randomized controlled trial with 42 participants, where some received zinc while others were given a placebo.
Results showed that zinc supplementation likely increased the bone mineral density (BMD) at the lumbar spine and hip after 12 to 18 months of treatment. This improvement in bone health could suggest potential benefits in pain relief, although the study didn’t directly measure back pain outcomes.
Even though the findings about BMD improvements are promising, we should be cautious. The trial didn't provide direct evidence on whether zinc specifically alleviates back pain. It’s essential to recognize that while we observed positive changes in bone density, interpreting this as a definitive solution for back pain would be premature.
Thus, further research is necessary to connect zinc's effects on bone health to actual pain relief in order to offer clearer guidance on its use as a treatment for back pain.

Zinc cream alleviates cold sores
A randomized clinical trial on the treatment of oral herpes with topical zinc oxide/glycine.
Most Relevant Research
We conducted a double-blind, placebo-controlled clinical trial to explore the effectiveness of a zinc oxide/glycine cream in treating cold sores caused by facial and circumoral herpes. By dividing 46 participants into two groups, one receiving the zinc treatment and the other a placebo, we aimed to measure how this formulation affected the duration and severity of cold sore symptoms.
Our results were quite promising! Participants who began using the zinc oxide/glycine cream within the first 24 hours of noticing symptoms experienced cold sore lesions that lasted only an average of 5 days, compared to 6.5 days for those on the placebo. Additionally, we noticed a significant reduction in the overall severity of their symptoms, including blistering, soreness, itching, and tingling.
As for side effects, subjects treated with the zinc cream experienced only minor and reversible issues typical of ionic zinc salt solutions. This indicates that the zinc oxide/glycine cream is not only effective but also safe for treating cold sores, presenting a valuable option for many people seeking relief from this common condition.

Zinc benefits heart health post-cisplatin
Role of zinc oxide nanoparticles supplementation on alleviate side effects of cisplatin induced cardiotoxicity in rats.
Most Relevant Research
We explored the potential benefits of zinc oxide nanoparticles (ZnONPs) in preventing heart damage caused by cisplatin, a powerful chemotherapy drug known for its efficacy but also for its side effects, particularly cardiotoxicity.
In our study, rats were divided into several groups, including control groups and those receiving different doses of ZnONPs. We specifically looked at a range of health markers such as lipid levels, antioxidant activity, and inflammation in heart tissues to see how ZnONPs could help soften the impact of cisplatin on heart health.
As we gradually increased the dosage of ZnONPs to 50 mg/kg, we observed significant improvements across the various health parameters examined. Notably, at this optimal dose, the rats' heart health markers showed a remarkable recovery, aligning closely with those in the healthy control group. This suggests that ZnONPs effectively protect heart tissue from oxidative stress and inflammation associated with cisplatin treatment.
Overall, our findings highlight the promising role of zinc oxide nanoparticles in mitigating heart damage linked to cancer treatments, paving the way for further research in this arena.

Zinc treatment for angina pectoris
High-dose zinc to terminate angina pectoris: a review and hypothesis for action by ICAM inhibition.
Most Relevant Research
We delved into an intriguing question: Can high doses of zinc help relieve chest pain caused by angina pectoris? Our research reviewed studies that highlight how zinc may play a role in managing this condition. Angina pectoris often results from arteriosclerosis, where the arteries become narrowed due to cholesterol buildup and other factors.
We discovered that patients with severe atherosclerosis showed promising improvements when treated with high-dose zinc. Specifically, a treatment regimen involved raising serum zinc levels significantly, resulting in symptom relief for many individuals. In one notable case, 12 out of 16 patients experienced measurable benefits, including one patient who also suffered from Raynaud's disease.
Furthermore, our analysis noted that long-term exposure to zinc in the environment correlated with reduced incidence of angina and ischemic events during exercise. Zinc appears to possess antioxidant properties, which may protect against the oxidation of LDL cholesterol, a key player in artery damage. By blocking certain inflammatory factors and promoting better circulation, zinc might enhance heart function and alleviate chest pain.
Based on these findings, we propose that zinc treatment should be considered a fundamental option in both prevention and therapy for atherosclerosis-related chest pain. This could lead to a renewed focus on restoring a healthier cardiac function among those affected by these conditions.

Zinc oxide combats foodborne pathogens
Active Packaging of Immobilized Zinc Oxide Nanoparticles Controls Campylobacter jejuni in Raw Chicken Meat.
Most Relevant Research
We set out to explore how zinc oxide nanoparticles (ZnO NPs) could help control the bacteria responsible for food poisoning in raw chicken meat. Our approach involved integrating these nanoparticles into packaging materials to see if they could effectively inactivate Campylobacter jejuni, a common and concerning pathogen in poultry.
Through our experiments, we discovered that immobilizing ZnO NPs in functional pads placed under raw chicken could dramatically reduce bacterial counts. In fact, we saw a reduction from about 4 log CFU to an undetectable level within just three days when storing chicken at 4°C. Notably, we monitored zinc levels in the chicken meat, confirming a safe release of zinc without any migration of nanoparticles onto the food. This means that we can help keep raw chicken safe and fresh without compromising its integrity or quality.
Not only did we find that these functional pads inactivated the harmful bacteria, but we also noted a related increase in lactic acid production, which plays a role in further protecting the meat. Our findings open up new avenues for using zinc in food packaging, offering a way to enhance food safety without directly adding chemicals to the food itself. Overall, this study highlights the potential for nanotechnology to play a significant role in managing foodborne pathogens like Campylobacter in poultry products.

Prevention of Recurrent Benign Paroxysmal Positional Vertigo: The Role of Combined Supplementation with Vitamin D and Antioxidants.
Most Relevant Research
This study examined the effectiveness of a nutritional supplement containing zinc, among other ingredients, in preventing the recurrence of benign paroxysmal positional vertigo (BPPV), a condition that can cause intense dizziness. We followed a diverse group of 128 patients with a history of frequent BPPV episodes. They were divided into three groups based on their vitamin D levels and received different treatment plans.
In one group, those with low vitamin D received a daily supplement containing zinc, along with other antioxidants and vitamin D3. We noticed a remarkable decrease in BPPV relapses in this group after six months compared to where they started. However, for the groups that had sufficient vitamin D and particularly those receiving zinc without vitamin D, we did not find significant benefits in reducing dizziness recurrence.
While zinc was part of a combined treatment approach, it didn’t demonstrate a standalone positive impact on dizziness. Our findings suggest that while zinc might play a role alongside other supplements, it shouldn't be solely relied upon for preventing BPPV relapses in patients with sufficient vitamin D levels.
