Zinc supplementation benefits MS models
Dietary zinc status is associated with ZnT3 (SLC30A3), IL-6 gene expressions and spinal cord tissue damage in spinal cord tissue in a cuprizone-induced rat Multiple Sclerosis model.
We explored how dietary zinc levels influence spinal cord damage and gene expressions associated with Multiple Sclerosis (MS) using a cuprizone-induced rat model. The study included 46 adult male Wistar rats divided into five groups, with some receiving zinc supplementation while others followed a zinc-deficient diet.
After eight weeks of treatment, we found that the rats with MS symptoms showed elevated markers of tissue damage and inflammation, particularly in the groups that lacked zinc. Notably, those receiving zinc supplementation exhibited significantly reduced levels of harmful substances, bringing them back closer to control levels.
Our findings highlight zinc's protective effects in a model of MS, suggesting that incorporating zinc into treatment plans could help alleviate some symptoms associated with this autoimmune disorder. This is promising for future treatment strategies for those affected by MS.

Zinc intake benefits RA bone health
The association between dietary zinc intake and osteopenia, osteoporosis in patients with rheumatoid arthritis.
We aimed to understand how dietary zinc intake influences the risk of developing osteopenia and osteoporosis in patients with rheumatoid arthritis (RA). Our study relied on data collected from the National Health and Nutrition Examination Survey, spanning several years. Through careful analysis using univariate and multivariate logistic regression models, we were able to uncover significant associations between dietary zinc levels and bone health in this population.
What we found was encouraging: higher zinc intake appeared to lower the chances of these serious bone conditions among RA patients. Our research also went further by examining various factors such as age, body mass index (BMI), and pre-existing health issues like diabetes and hypertension. This comprehensive approach led us to conclude that adequate dietary zinc is crucial for maintaining bone health in individuals with RA, though we noted the need for more extensive long-term studies to corroborate these findings and delve deeper into the underlying mechanisms at play.

Zinc transport's role in T cells
SLC39A10 is a key zinc transporter in T cells and its loss mitigates autoimmune disease.
We identified an important link between zinc transport and autoimmune disorders, specifically focusing on the protein SLC39A10 and its role in T cells. Through our study, we discovered that two specific genetic variations in the SLC39A10 gene are associated with inflammatory bowel disease (IBD). To further explore this connection, we created genetically modified mice with a targeted deletion of the Slc39a10 gene in T cells.
Our findings revealed that the loss of SLC39A10 significantly protects against the progression of both IBD and experimental autoimmune encephalomyelitis (EAE). Notably, we also observed that the absence of this transporter led to increased cell death, independent of common pathways usually associated with apoptosis. This indicates that SLC39A10 plays a crucial role in maintaining the health of T cells by facilitating zinc import, which is essential for DNA replication when T cells are activated.
Our research contributes to a deeper understanding of how zinc homeostasis impacts immune function. The insights gained from this study suggest that targeting zinc transport could present new therapeutic options for managing T cell-related autoimmune diseases.

Zinc's role in alopecia areata
Association Between Serum Trace Elements Level and Alopecia Areata: A Systematic Review and Meta-Analysis.
We analyzed how zinc levels in the body relate to alopecia areata (AA), an autoimmune disorder that affects hair loss. Our research involved a systematic review of 34 studies, gathering data from nearly 5,000 participants across 16 countries. By examining various studies, we sought to understand if zinc supplementation could be beneficial for those suffering from AA.
The results were striking. We found that individuals with alopecia areata had significantly lower levels of zinc and vitamin D compared to healthy individuals. Specifically, the data indicated that those with vitamin D deficiency faced a heightened risk of developing AA. This suggests that replenishing these nutrients might help manage the disease.
Importantly, we didn't find a significant difference in copper levels between AA patients and healthy controls, indicating that not all trace elements play the same role in this condition. Overall, our findings highlight the potential of zinc and vitamin D as targeted treatments for alopecia areata, offering new hope for those affected by this condition.

Zinc supplementation eases neutrophil activity
Zinc Supplementation Reduces the Formation of Neutrophil Extracellular Traps by Decreasing the Expression of Peptidyl Arginine Deiminase 4.
We aimed to explore how zinc supplementation might influence immune responses, particularly focusing on neutrophil activity in the context of autoimmune diseases. To do this, we simulated inflammatory conditions typically seen in such disorders using specific cytokines, interleukin-17 (IL-17) and tumor necrosis factor (TNF)-α.
Our findings indicated that elevating zinc levels significantly reduced the formation of neutrophil extracellular traps (NETs), which are often implicated in tissue damage during autoimmune flare-ups. We also discovered that zinc supplementation lowered the expression of a protein called peptidyl arginine deiminase 4 (PAD4), which is associated with NET formation.
Interestingly, zinc not only decreased harmful neutrophil activity but also boosted the production of beneficial proteins like interleukin-1 receptor antagonist (IL-1RA) and IL-8 in the activated cells. Overall, maintaining adequate zinc levels seems crucial for preserving healthy immune function and preventing the harmful overactivity of neutrophils, suggesting its potential as an adjunct treatment in managing autoimmune conditions.
I ordered this zinc as my doctor mentioned that my eczema resulted from a zinc deficiency. After taking it for three days, I noticed significant improvement; the eczema on my arm became less inflamed and stopped itching. Over two weeks later, I hardly experience any issues.

An autoimmune disorder occurs when the body's immune system mistakenly attacks its own healthy cells and tissues, believing them to be foreign invaders, such as bacteria or viruses. This reaction can lead to inflammation, tissue damage, and impaired function of the affected organs. There are over 80 known autoimmune diseases, including rheumatoid arthritis, lupus, multiple sclerosis, and type 1 diabetes, each with its own specific symptoms and treatment options. The exact cause of these disorders is still unclear, but a combination of genetic, environmental, and hormonal factors is believed to play a role in their development.
Diagnosis of autoimmune disorders often involves a combination of physical examinations, assessment of symptoms, blood tests, and imaging studies to evaluate organ involvement. Treatment typically focuses on managing symptoms and controlling the immune response using medications such as corticosteroids, immunosuppressants, and biologics. In addition to medication, lifestyle modifications, such as stress management and a balanced diet, can be beneficial in managing symptoms. If you suspect you have an autoimmune condition, it's important to consult a healthcare professional for proper evaluation and tailored treatment options.
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 plays a crucial role in immune function and has been studied for its potential benefits in managing autoimmune disorders. This mineral is essential for the development and function of immune cells, and adequate levels may help modulate inflammatory responses. Some studies suggest that zinc supplementation may help reduce the severity of symptoms in certain autoimmune conditions, like rheumatoid arthritis and lupus, by influencing immune responses and reducing oxidative stress.
However, it's important to note that while zinc may offer supportive benefits, it should not be regarded as a standalone treatment for autoimmune disorders. The relationship between zinc and autoimmune diseases is complex; excessive zinc intake can also lead to adverse effects, including interference with other essential minerals. Therefore, anyone considering zinc supplementation, especially those with autoimmune disorders, should consult a healthcare provider for personalized advice and to determine the appropriate dosage. Keeping a balanced diet rich in nutrients, including zinc, can contribute to overall immune health.
Based on user reviews, the timeline for seeing results from zinc supplementation can vary considerably, but many users report improvements within a few days to a few weeks of consistent use. For example, one user indicated a significant improvement in their eczema within just three days of starting the supplement, noting that inflammation and itching were greatly reduced (Read Review). Another user reported noticeable improvements in their skin after over a month of use, which suggests that while some may experience rapid benefits, others might take longer to notice effects (Read Review).
Additionally, users taking the supplement for issues like hair loss have reported visible improvements within a week, indicating that this nutrient can begin to deliver benefits relatively promptly (Read Review).

Zinc intake influences autoimmune risk
Higher dietary zinc intake increases the risk of autoimmune thyroiditis.
We examined the connection between dietary zinc intake and the risk of autoimmune thyroiditis (AIT), particularly focusing on Hashimoto's thyroiditis. The study analyzed data from the 2007-2008 National Health and Nutrition Examination Survey, including nearly 5,500 participants—273 with AIT and 5,194 without it.
Our findings revealed that higher dietary zinc intake is associated with an increased risk of AIT, acting as an independent risk factor. This is concerning, as excessive zinc could disrupt our immune balance, potentially leading to other autoimmune disorders.
While it’s clear that zinc plays a role in thyroid health, we must be cautious about how much we consume. The study suggests that dietary zinc should be carefully monitored in those at risk for AIT, and it highlights the need for further research to establish safe consumption levels.
