Randomized, multicenter, active-controlled open-label study of NPC-25, zinc histidine hydrate, (non-inferiority to NOBELZIN™, zinc acetate dihydrate) for patients with hypozincemia.
We conducted a study to evaluate how effective NPC-25, a new form of zinc, is compared to a well-known treatment, NOBELZIN™, for patients with low zinc levels. Participants in this trial had their zinc levels checked and were grouped to receive either NPC-25 or NOBELZIN™.
For a period of up to 24 weeks, we aimed to maintain their zinc levels within a specific target range while closely monitoring for side effects. One of our main goals was to see if NPC-25 could maintain these target zinc levels similarly to NOBELZIN™.
Our findings revealed that NPC-25 was indeed non-inferior to NOBELZIN™, meaning it worked just as well. Importantly, we also observed that those taking NPC-25 reported fewer digestive issues, like nausea and vomiting. This suggests that while both treatments were effective, NPC-25 might be the gentler option.

Zinc treatment in hypozincemia study
Post-marketing surveillance of zinc acetate dihydrate for hypozincemia in Japan.
We explored the impact of zinc acetate dihydrate on several symptoms, including nausea, through a comprehensive study that assessed its safety and effectiveness for treating hypozincemia over a 52-week period. From the data collected, we observed an overall adverse reaction rate of 9.4%, with nausea reported in 1.4% of patients.
Despite nausea being a concern, the benefit of zinc acetate dihydrate for other indications was notable, with an efficacy rate of 83%. For patients experiencing symptoms such as pressure ulcers or stomatitis, the effectiveness was strikingly high. However, the specific effect of zinc on nausea is not definitively isolated within the study results, making it hard to gauge its direct and unique benefits.
In essence, while zinc acetate dihydrate shows promise for a variety of symptoms, including nausea, the evidence does not conclusively highlight its effectiveness for this particular issue on its own. Overall, it appears that zinc treatment can contribute positively to addressing several related health problems.

Zinc affects post-op nausea minimally
Comparing the Effect of Zinc-impregnated Pharyngeal Packs with Conventional Methods on the Level of Sore Throat Among Patients Undergoing Septorhinoplasty.
We explored the effectiveness of zinc-impregnated pharyngeal packs in reducing post-operative nausea and sore throat among patients undergoing septorhinoplasty. In this study, we divided 220 patients into four groups, each receiving different types of pharyngeal packs: normal saline-impregnated vibril, normal saline-impregnated gauze, zinc solution-impregnated vibril, and zinc solution-impregnated gauze.
Our findings revealed that there was no significant difference between the groups regarding the occurrence of sore throat shortly after surgery and at various intervals thereafter. However, we did observe that those using zinc solution-impregnated gauze experienced significantly less severity of nausea two hours post-surgery compared to those using normal saline-impregnated gauze. Ultimately, while zinc did not help with sore throat, it showed promise in alleviating nausea.

Zinc's tolerability in diarrhoea treatment
New formulation zinc sulphate acceptability and adherence in children with acute diarrhoea: A prospective, open-label, interventional study in Bangladesh.
We aimed to understand how zinc tablets, often recommended for treating diarrhoea in young children, affect nausea and overall treatment adherence. In this open-label study, we involved children aged 3 to 59 months who visited the outpatient department at Dhaka Hospital.
Our findings revealed that a significant number of children, about 92.7%, tolerated the modified zinc tablets well. However, we also noted that 32.8% of the children experienced vomiting, and 19.5% had regurgitation, while a smaller number, 7.4%, reported nausea. Interestingly, despite these side effects, a remarkable 99.3% of caregivers expressed their willingness to continue using this zinc formulation in the future.
Overall, while our study demonstrated that the modified zinc formulation was generally well-tolerated, we cannot overlook the considerable instances of nausea and vomiting experienced by the children. Balancing these side effects with the willingness of caregivers offers a complex view of zinc's role in diarrhoea management.

A wonderful form of zinc! It is crucial during the pandemic for boosting the immune system, even surpassing vitamin C. I've noted excellent relief from symptoms, and I advise doubling the intake currently. It's vital to take zinc with a hearty meal to avoid nausea. Many who experience nausea are likely using it incorrectly. Consider taking 3 capsules, especially a citrated or picolinate form for better absorption.
Nausea is a sensation that often precedes vomiting and is characterized by an uneasy feeling in the stomach. It can be caused by a variety of factors, including motion sickness, certain medications, food poisoning, or underlying health conditions. The experience of nausea can range from mildly uncomfortable to intensely distressing and is often accompanied by other symptoms such as sweating, increased salivation, or a feeling of lightheadedness.
Many people experience nausea at some point in their lives, making it a common issue. Fortunately, there are several remedies and treatments available that can help alleviate this unpleasant sensation. Over-the-counter medications, home remedies like ginger tea, and lifestyle changes, such as eating smaller meals or avoiding certain triggers, can be effective in reducing nausea. However, if nausea is persistent or accompanied by severe symptoms like severe abdominal pain or fever, it’s essential to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
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.
Zinc may play a role in alleviating certain types of nausea, especially when it is associated with specific conditions, such as pregnancy or certain gastrointestinal issues. Some studies have indicated that zinc supplements might help in reducing nausea symptoms due to their potential to support overall gut health and maintain immune function. However, the evidence is not conclusive, and results can vary from person to person.
It's important to note that while zinc supplementation might benefit some individuals, it is not universally effective for all types of nausea. If you're considering using zinc to address nausea, consult with a healthcare professional to ensure it's appropriate for your situation and to discuss the ideal dosage. Additionally, it's crucial to address the underlying cause of nausea rather than just treating the symptom itself.
Based on user reviews regarding the use of zinc supplements for nausea, the timeline for noticing results can vary significantly. Many users report experiencing positive effects after a few days to a couple of weeks. For instance, one user mentioned that after two and a half months of taking Zinc Picolinate, they felt calmer and noted improvements in skin and hair without experiencing nausea Read Review. Another user indicated that after ten days, they observed a halt in hair loss, implying a positive shift in their condition Read Review.
However, there are also mixed experiences; some users reported nausea regardless of timing or dosage, while others found that taking it with food was crucial in preventing such side effects Read ReviewRead Review. Ultimately, while some users see benefits within days or weeks, it may take longer to achieve consistent results, making it essential to consider individual responses to the supplement.
The effectiveness of zinc supplements for alleviating nausea is supported by several studies, although the evidence is somewhat mixed. For instance, one study found that participants using zinc solution-impregnated gauze reported significantly less severe nausea two hours post-surgically compared to those not receiving zinc [3]. This suggests that zinc may offer some benefits in specific contexts, particularly related to post-operative nausea.
However, another research highlighted that while zinc acetate dihydrate has a beneficial impact on multiple symptoms, including nausea, the evidence does not clearly isolate its effectiveness for nausea alone [2]. Moreover, while a high tolerance for zinc tablets was noted among children, a notable percentage still experienced nausea and vomiting [4]. In summary, while zinc appears to hold promise for nausea relief in certain situations, more targeted studies are needed to establish its efficacy directly for this symptom.
Based on user reviews, many individuals have reported various improvements in their health after taking zinc supplements. A number of users highlight benefits such as enhanced skin health, improved hair growth, and a boost in overall immune function. For instance, after 2.5 months of using Zinc Picolinate, one user noted a calming effect along with improved hair and skin conditions without experiencing nausea Read Review. Another user shared that they observed a cessation of hair loss within just ten days of starting supplementation, further testifying to its efficacy Read Review.
However, it’s important to note that individual experiences can vary significantly. While many users found success in taking zinc, especially when consumed with meals to mitigate nausea Read Review, others did report adverse effects such as headaches and persistent nausea Read Review. Some users emphasized the importance of proper timing and dosage, suggesting adjustments if side effects occur, which can greatly influence the overall satisfaction with zinc supplementation Read Review.
Based on user reviews, many individuals have reported that combining zinc supplements with food significantly helps mitigate nausea, which is a common concern among users. For instance, several reviewers emphasized that taking zinc right after meals prevents adverse effects, allowing them to experience its benefits without discomfort Read ReviewRead Review. One user even recommended a regimen of taking zinc alongside other vitamins, such as vitamin C and selenium, to enhance absorption while ensuring that they do not experience nausea Read Review.
Conversely, there are reports of some users experiencing nausea regardless of meal times, indicating that individual responses can vary significantly Read Review. A few users noted that adjusting the timing of their zinc intake—either taking it an hour before meals or two hours after—helped alleviate nausea and improved their overall experience with the supplement Read Review. Ultimately, while many users advocate for taking zinc with food for better tolerance and effectiveness, there are also recommendations for careful dose adjustments to counteract any gastrointestinal discomfort.
Users report that taking zinc with food significantly reduces the likelihood of nausea. Many reviewers emphasize the importance of consuming zinc after meals to avoid any unpleasant side effects (review id='b53df030-60f5-47dd-8ff2-4093c17961bb', review id='1298d514-5a65-478c-9c25-47e4188cd537', review id='4ab6137e-6f38-4629-abbd-ed45e4bc6c28'). Some users share that they experienced nausea when taking zinc on an empty stomach, but this was not an issue when taken with food (review id='099044c2-dda0-40df-90c5-7bc44ec92986', review id='c879b8aa-1289-42a8-8b79-74a79c0641c5').
In terms of dosage, users have different experiences, with some recommending a higher intake, especially during times of illness, like when catching a cold Read Review. However, there are cautionary notes, as taking more than recommended could lead to nausea if not paired with adequate food intake Read Review. Overall, many agree that sticking to the recommended dose, especially with a hearty meal, is key to minimizing side effects like nausea while maximizing the benefits of zinc supplementation.

No nausea felt
Hi everyone, today I'd like to discuss Zinc Picolinate from Solgar. This trace element is often overlooked, yet it assists women in balancing hormones, enhancing mood, and improving skin and hair. After 2.5 months of taking it, I feel calmer, my hair loss has ceased, and my skin has improved. I experienced no nausea or dizziness, taking just one tablet daily as suggested by the manufacturer.

Causes nausea sometimes
Zinc glycinate is a good form; it's highly digestible. The suggested dosage is 22 mg per tablet. You can take up to 50 mg daily. If you catch a cold, you might take three tablets at once, but it could cause nausea if taken on a full stomach.
