Summary is adults need at least 8000 IU of Vitamin D per day. This confirm what I have suspected since almost a decade. I have been taking 5k Vitamin D per day since one of my cousin had serious health issues because of low vitamin D for 3 years and as soon as she started having 5k IU per day, they disappeared within a month.
