We evaluated how a specific mix of vitamins and minerals, including selenium, influences recurrent colds in a group of 192 patients over 16 weeks. This randomized, placebo-controlled study showed that those receiving the micronutrient combination experienced a greater improvement in cold symptoms compared to the placebo group.
Notably, individuals below 45 reported fewer job absences due to colds. Overall, vitamin and mineral levels increased significantly for those on the treatment, suggesting that micronutrients may enhance immune defense and reduce the severity of common colds. However, the specific role of selenium in these improvements needs more exploration.

We explored how a combination of vitamins and minerals, including selenium, impacts the frequency and severity of common colds in patients prone to upper respiratory infections. In a rigorous 16-week trial involving 192 participants, we found that those receiving the micronutrient blend reported significant improvements in their cold symptoms compared to the placebo group.
Specifically, symptoms improved more in individuals with severe colds, and younger patients had fewer work absences due to illness. Overall, the study supports the beneficial role of micronutrients like selenium in boosting immune defenses against recurrent colds.

Less illness
This selenium is excellent and has improved my thyroid function. I've noticed fewer illnesses, and during common colds, I tolerate them well. It's also an effective detoxifier and antioxidant. My skin has cleared up, and inflammation has reduced significantly. The quality of the product is very high.
