Zinc treatment reduces nausea risk
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.

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
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.

This zinc is exceptional and far better than the expensive duds sold in pharmacies. I experienced no nausea or stomach pain with this product, unlike others. I recommend taking it during meals, and I've noticed positive effects on my skin and hair. Just avoid taking it with calcium for best results.

For me, zinc picolinate is one of the best forms. It has produced results, especially during colds. It's important to take it after meals to avoid nausea. I recommend not exceeding 1-3 weeks of usage without checking for deficiencies. The packaging is ample enough for seasonal use.

Zinc's tolerability in diarrhoea treatment
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.

Nausea possible

Take zinc with meals to avoid nausea on an empty stomach and not with calcium or iron. Zinc is crucial for immunity, hair growth, and overall health. I chose zinc picolinate for its good bioavailability. The dosage of 25 mg is suitable for adults.

Zinc Picolinate is said to protect the immune system. Unfortunately, I cannot take it as I experienced nausea immediately after consumption each time, rendering it unacceptable for me.

Prevents nausea

A good form of zinc; I take it at the first sign of an upper respiratory infection. I prefer the capsules and recommend taking them after meals to avoid nausea. You shouldn't use it for a prolonged period as it competes with copper, or follow your doctor's advice regarding levels.

This zinc product is easy to take, with no aftertaste or nausea. I take one nightly alongside magnesium and have started to feel the positive effects. However, I worry that the 50mg dose exceeds the daily maximum of 30mg, which could affect copper levels.

Managing nausea

Zinc is effective for boosting immunity. However, taking too much may result in nausea or headaches; if 50mg feels excessive, consider taking less. My delivery arrived on the 17th and 21st of November with an expiry of 26th March.
