We explored the protective effects of selenium nanoparticles (SeNPs) against the harmful impacts of zearalenone (ZEA), a toxin from grains that can disrupt gut health. In a controlled setting, we observed that ZEA damages intestinal cells, leading to inflammation and increased permeability.
Our findings showed that SeNPs can counteract this damage by enhancing antioxidant activity and improving gut microbiota balance. Despite these promising results, it’s crucial to note that the effectiveness of SeNPs in humans still requires further investigation.

We investigated whether selenium has a protective effect against the harmful impacts of aflatoxin B (AFB), a common toxin found in food. By studying broiler chickens over three weeks, we set up different groups to see how selenium influences cell death caused by AFB.
Our findings showed that selenium supplementation significantly reduced excess cell death in the jejunum, helping restore key biological markers to healthier levels. This research helps highlight selenium's potential as a protective agent against food-related poisonings.

We explored the potential of selenium-enriched Kazachstania unispora KU2 in alleviating intestinal injuries caused by the foodborne toxin patulin (PAT). Our investigation revealed that both the standard K. unispora and its selenium-enriched version helped reduce inflammation and restore gut health.
Interestingly, the selenium-enriched variant showed even greater effectiveness. It seemed to work by enhancing the production of a specific protein, SEPP1. We verified that a healthy gut microbiota was essential for these positive effects. This study hints at promising treatment options for intestinal diseases linked to foodborne toxins.

Reduced antibody levels

An excellent dosage of 200mcg for thyroid issues, while a lower dosage of 100mcg is advisable for prevention. My endocrinologist recommended I maintain selenium intake due to an increase in antibodies. After several months of taking selenium, these antibodies decreased. I alternate my intake every month and find this approach highly beneficial compared to the more expensive Cefasel. I buy from Now Foods and am very pleased with the quality and price.

I was prescribed selenium for autoimmune thyroiditis and took it for three months. I began to feel more energetic and less fatigued. Additionally, I combined it with vitamin D-3 and L-Tyrosine from the same company. Selenium is essential for women, and one should strive to consume at least 100 μg daily.

We explored how selenium might help counteract food poisoning, particularly focusing on kidney damage caused by T-2 toxin. In our study with New Zealand rabbits, we conducted a controlled trial, giving various doses of selenomethionine alongside a toxic agent.
We observed that the toxin induced significant kidney impairment and increased inflammation. Interestingly, rabbits pretreated with a low dose of selenium showed reduced oxidative damage and inflammation. This suggests that selenium could play a protective role against certain types of food poisoning, specifically in kidney health.
