We examined how selenium, a trace element known for its role in health, can help those suffering from allergic dermatitis. In our exploration, we focused on how selenium nanoparticles, specifically designed for easier manufacturing and use, can activate the body's natural defenses against allergies.
The study highlighted how selenium impacts allergic reactions by enhancing the production of selenoproteins, which are crucial in regulating inflammation and oxidative stress. We saw that these selenium nanoparticles effectively inhibited mast cell activation. Mast cells are known to release substances that can trigger allergic reactions, so by reducing their activation, the potential for severe allergic responses decreased.
Additionally, through a series of experiments on allergic mouse models, we confirmed the nanoparticles increased selenium levels in the skin, which led to a reduction in inflammatory cells and mast cell activation. The results indicated significant therapeutic benefits, providing a promising avenue for managing allergic reactions.
Ultimately, this study not only demonstrates the innovative use of selenium nanoparticles in treating allergies but also emphasizes the importance of scaling up their production for broader clinical application.

We explored the role of selenium-rich tea polysaccharides (Se-TPS) in managing allergies, focusing on how they influence immune responses and gut health. Using a method called high hydrostatic pressure, we extracted Se-TPS at a pressure of 400 MPa for a specific duration. This process allowed us to isolate several polysaccharide components, particularly Se-TPS3-4, which turned out to be the most effective.
Our research involved both laboratory experiments and tests on mice sensitized to a specific allergen. We observed that these polysaccharides reduced the release of various inflammatory substances, including histamine and interleukin-4, both of which are known to play roles in allergic reactions. In the treated mice, levels of undesirable immune markers decreased, while those associated with a balanced immune response increased.
Importantly, we found that Se-TPS also encouraged the growth of beneficial gut bacteria, such as Lactobacillus, while enhancing metabolites that can support overall gut health. These findings indicate the strong potential of selenium-rich tea polysaccharides as a natural way to reduce allergic reactions by improving immune balance and gut microbiota.

We investigated the impact of dietary selenium on cow's milk allergy, a common condition affecting infants. In our study, we used a mouse model and sensitized three-week-old female C3H/HeOuJ mice with whey protein and cholera toxin. These mice were then divided into groups and fed diets with varying levels of selenium: control, low, medium, or high.
After subjecting the mice to a whey challenge, we noted some interesting changes. Notably, the body temperature of mice on a medium selenium diet was significantly higher 60 minutes post-challenge, suggesting a less severe allergic reaction. We also observed decreased levels of allergen-specific immunoglobulin E and reduced release of mouse mast cell protease-1, indicating a dampened immune response.
This research points towards selenium supplementation as a potential method to modulate allergic reactions to whey. By lowering specific antibody responses and mast cell activity, selenium might help lessen the severity of allergies associated with cow's milk. Overall, our findings could open up new avenues for managing food allergies effectively.

I had eczema on my hands due to my heavy metal allergies, especially from nuts and cocoa. After taking selenium, my fingers returned to their clean condition within days, which surprised my family! Selenium aids in detoxifying heavy metals like mercury and protects against oxidative damage. I take 1-2 pills daily and wish to continue.

Selenium compound reduces allergy symptoms
We explored how a novel water-soluble selenium compound, known as SeTal, impacts atopic dermatitis (AD), a common allergic skin condition. In experiments, we applied 2,4-dinitrochlorobenzene (DNCB) to sensitized mice, creating a model for AD symptoms. By treating these mice with either SeTal or hydrocortisone, we aimed to measure the severity of skin lesions and related inflammation.
The results were compelling. SeTal, at concentrations of 1% and 2%, showed significant effectiveness in reducing the symptoms and inflammatory indicators of AD. In fact, the results were comparable to, and in some cases, even better than the results achieved with hydrocortisone, a traditional steroid treatment often used for such conditions.
This study suggests that SeTal could offer a promising alternative for treating atopic dermatitis, providing a new avenue for those seeking relief from this chronic and often bothersome allergy-related skin issue. With common steroid treatments posing potential side effects, our findings around SeTal support exploring safer, more effective options in the future.

We examined how seleno-L-methionine, a form of selenium, impacts allergic reactions. In our study, female mice were sensitized to a common allergen, ovalbumin, and then given selenium for two weeks before being re-exposed to the allergen to trigger an allergic response.
Our findings showed that selenium significantly reduced allergic reactions in a dose-dependent manner, cutting down specific immune responses associated with allergies. Notably, levels of certain inflammatory markers decreased, suggesting selenium might help regulate allergic responses in the body.

A wonderful product that I can take once or twice a year. I bought it for my mother to alleviate her spring allergies and boost her immunity. She takes a pill every evening, and selenium is vital for maintaining thyroid function, as advised by Dr. Berg and Dr. Karim.

Perfect match
The Now brand is an excellent supplement for me. I usually react to many supplements, but this one does not cause me issues. It greatly helps with my nickel allergy and allows me to tolerate the iodine I need.

Causes allergy symptoms
Selenium works well but causes allergic reactions for me. I should try the smallest package to see if it's suitable. The quality is good, ingredients are well composed, and the taste is acceptable.

We explored the connection between selenium, a key dietary micronutrient, and its effects on three common allergic diseases: allergic asthma, atopic dermatitis, and allergic rhinitis. Using a rigorous Mendelian randomization approach, we aimed to better understand if higher levels of selenium in the body could actually help reduce the risk of these allergies.
Our findings revealed that increased serum selenium concentrations are linked to a lower risk of allergic rhinitis. This suggests that selenium might play a beneficial role in managing this particular allergic condition. It's important to note, however, that while selenium shows promise for allergic rhinitis, we didn't find it connected to significant improvements in allergic asthma or atopic dermatitis.
This study encourages further exploration into how different micronutrients, including selenium, might influence allergic responses. The results highlight the need for ongoing research to clarify the role of dietary supplements in allergy prevention and management.

Prenatal selenium reduces allergy risk
We delved into the connections between prenatal exposure to certain metals—specifically, selenium, mercury, and manganese—and the risk of allergic diseases during early childhood. Using data from 94,794 mother-infant pairs from the Japan Environment and Children's study, we analyzed maternal blood samples taken during mid-pregnancy to assess levels of these metallic elements.
Our findings point to a promising role for selenium: it appears to be linked with a reduced risk of atopic dermatitis, food allergies, allergic rhinitis, and overall allergic diseases in children by their third birthday. Notably, this beneficial effect seems even more pronounced when mercury exposure during pregnancy is lower.
While we also explored the interaction between selenium and mercury, the highlights of our results firmly place selenium in a positive light regarding its potential to mitigate allergy risks in early childhood.
