I have been spending a lot of time looking at Vitamin D (and zinc) with regards to Covid and have even been corresponding with NICE on this. NICE still don't seem convinced, but given :
- the number of studies out there showing strong correlation between Vitamin D levels and Covid outcomes
- one study even showing much improved outcomes for patients admitted to hospital given a high dose shot of a form of Vitamin D
- the fact that Covid died down in summer (in the Northern Hemisphere) and has now come back again in Autumn.
- BAME individuals have much higher death rates in the UK, but not in their native countries.
- I have seen a study which shows in 2019 the UK had one of the lowest levels of Vitamin D serum levels in Europe.
- Japan with their seafood diet, high in Vitamin D and Zinc, have low levels of Covid 19
seems to me strong proof that Vitamin D matters. Vitamin D is the only Vitamin that Public Health England recommends people do supplement for bone health in the winter (or if you are BAME or work indoors, which is almost everyone).
But whilst looking at that I also noticed this study about Vitamin D and type 1 Diabetes
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2994161/
CONCLUSIONS:
There was an observed effect of vitamin D supplementation on glycemic control in vitamin D-replete, type 1 diabetes mellitus patients. Further studies are needed to determine if these findings are applicable....
I also noticed that my son, who is the type 1, appears to have better control after supplementing with Vitamin D. It may event be that Vitamin D levels are protective against type 1 in the first place.
So given that most in the UK are Vitamin D deficient I would recommend that you supplement. From my understanding it is best, for heart health, to take Vitamin D with Vitamin K or eat Vitamin K foods with your Vitamin D supplement.
So does anyone here supplement, and if they do, do they notice improved control?
As always do your own research.
