Vitamin D is often referred to as the “sunshine vitamin,” and it plays a vital role in various bodily functions. However, in many parts of the world, vitamin D deficiency is prevalent, especially among those living in colder climates and spending less time in the sun. Let’s explore why we should consider vitamin D supplementation based on scientific evidence.
Research conducted in Portugal revealed that around 66% of adults had vitamin D3 deficiency. Additionally, studies conducted across the European population indicate an epidemic of vitamin D3 deficiency, affecting approximately 40% of Europeans, whose levels are considered insufficient. This deficiency tends to be more prevalent during the winter months when sun exposure is reduced. [1][2]
Several studies have examined the relationship between vitamin D3 supplementation and cancer incidence and mortality. Vitamin D3 does not appear to reduce cancer incidence, except in the case of colon cancer [6]. However, it significantly reduces the mortality of most cancers. [. [3][4][5]
Some studies show that vitamin D3 supplementation may play an important role in mood regulation and reducing the risk of depression. [7][8][9]
Vitamin D3 supplementation reduces the likelihood of developing a respiratory infection by up to 36%, according to a meta-analysis of randomized controlled studies, which included 10 studies and a total of 4,859 participants. [10]
Studies gathered in meta-analyses indicate that vitamin D3 supplementation has the potential to significantly reduce levels of bodily inflammation. This effect appears to be consistent across a wide range of studies conducted in this area. [11][12][13][14]
Several controlled studies have shown that vitamin D3 supplementation was able to significantly reduce the incidence of migraines. [15][16]
