The topic of vitamin D supplementation has been so controversial. Even before the pandemic scientists couldn’t seem to agree on what dose is best or when supplementation is a good idea.
There is a tonne of research now on vitamin D as it pertains to COVID-19 and auto-immune diseases, but none of this has really been conclusive as to whether it actually reduces the severity of disease.
This video discusses why low levels of Vitamin D may be an underlying indicator of metabolic disease and increased inflammation in the body more than anything else.
In the video we discuss:
What factors influence the production of Vitamin D in the body.
The impact of inflammation and metabolic stress on Vitamin D levels.
How natural light is an important contributor to the production of Vitamin D, Melatonin, and reduced levels of inflammation.
The negative impact of high dose Vitamin D & Vitamin C over time.
Tips for getting the most benefit from Vitamin D supplementation.
