On the rare occasion, viruses or bacteria manage to breach the system and make us sick. Understanding how natural immune system boosters work is dependent on our understanding of the factors that prohibit the immune system from doing its job properly.
Like any system, it works best when all integrated processes and structures are in harmony with one another. Helping to balance your immune system is the central goal and concept behind natural immune boosters. So when we consider the idea of boosting our immune systems, perhaps in anticipation for the change of season or because we feel a little under the weather, we need to understand that it is about keeping certain mineral and vitamin requirements up to standard for the system to work at its optimal level. Unfortunately, science is yet to discover a way to literally increase the ability of the immune system to fight of disease, especially once it is contracted, but we can still use natural immune boosters as a preventative measure and a way to help the system do what it does, well.
Balanced nutrition is one of the best ways to do this. Blood tests will reveal certain deficiencies in different individuals. Natural immune boosters like multivitamins can help to balance deficiencies, especially by reintroducing infection fighting micronutrients like selenium, vitamin A, vitamin B2, vitamin B6, vitamin C, vitamin D and zinc. Good natural immune system boosters typically include these nutrients as a daily supplement for use until balance is achieved.
Another way to help the immune system work well is by limiting the oxidisation of free radicals in the blood. Free radicals are unstable particles which become reactive and can harm other cells. They accelerate the spread of disease. Natural immune boosters will typically include antioxidants as well as a way of limiting the oxidisation of free radicals.
Although science has been reluctant to accept the causal relationships between psychological stress and the functioning of the immune system, it is becoming more established that emotional stress does directly affect various processes. Again, this is normally directly related to hormonal imbalances. Natural immune system boosters tend to include herbal ingredients that help with these imbalances.
