Lavenderain and Yddraigoldragon ,
glad to hear you are feeling the effects of being replete in Vitamin D.
It will most likely be many months until your body can repair itself, but in your cases, it has started to happen quite quickly.
Try and get into - "good nutrition" for yourself , it was not an accident , that the gov'ment recently advised that 7 veg and fruit were better for you than 5 items. Vitamin D enables you to use that nutrition.
To my mind , it is a very sad thing , that on these forums, many, many people have entirely preventable health problems. The knowledge is there, but not widely distributed.
In a few years time ( 2017- 2018 ) , the results of the VITAL and VIDAL studies will be released. These are double blind, placebo controlled studies of many thousands of people, which , HOPEFULLY , will be accepted as a definative statement about some of the benefits of Vitamin D.
Just out of interest, ..... there is a cohort of participants , the grassrootshealth cohort, about 7 thousand people, who have raised their level of vitamin D , to over 100 , by supplementation. Their rate of develping diabetes has dropped to about one tenth of the common "westerner" rate, in the USA. Traditionally, this would not be considered as sufficient proof of an effect, because it was " self selected" , however, it is very interesting , to say the least.
IF anyone has high blood sugar levels , pre-diabetes , etc , then it may be advisable to make sure your Vit D level are over the 100 range. Preferably 120 - 140 .
( That does not mean that type 1 diabetes can be reversed, however research into both insulin sensitivity and insulin resistance has shown that Vitamin D definately has some beneficial effects and may very well be helpful, particularly if you are at risk of developing Type 2 diabetes.)
