3. Vitamin D Supplementation
Vitamin D and vitamin D analogs have been shown to be highly effective when it comes to treating psoriasis and much more so than placebo. This makes sense when you consider the importance of vitamin D in strengthening the immune system.
A recent study has shown that vitamin D might actually be just as effective as some vaccinations when it comes to preventing colds and flus and that it could potentially prevent thousands or even millions of people from getting ill each year if we all took it as a supplement.
