I understand what you mean — I've also felt more than once that regular supplements don't work as effectively as I would like. I recently came across an article that discusses an approach that goes beyond traditional vitamins or herbal teas. This text examines in detail how cell therapy can positively affect the immune system, especially during the cold season when our defenses often "fail." In particular, the author describes how certain cellular methods help support immunity, regeneration, and overall body tone — https://ways2well.com/blog/winter-wellness-how-stem-cell-therapy-can-boost-your-immune . The article explains that this is not magic, but a more scientific approach to strengthening the body's natural defense mechanisms. I read it and thought that for people who are serious about their health, such information could become a new tool in their self-care arsenal.
