Optimal vitamin D intake may be at least 2,000 IU daily
As most people supplementing with vitamins know, the daily RDA for vitamin D has been set at 400 IU (in some countries up to 800 IU) daily, despite no evidence that such doses do anything beneficial, including even the basic target - preventing rickets. More recent studies have argues that the...- haidut

Higher doses of vitamin D, other steroids, may be needed in obese people
The title, at least in regards to vitamin D, is something Ray commented quite a few times when people asked him what the optimal dose for raising vitamin D levels was.

Vitamin D deficiency and low, not high, dopamine drive schizophrenia

Vitamin D is a ‘Game Changer’ for Patients With GI Cancers

Vitamin D may prevent atrial fibrillation (afib)
Some good news to all the people with this condition.

Vitamin D may prevent dementia / Alzheimer's Disease (AD)

Vitamin D supplementation may lower suicide risk by 50%

Another way to phrase the findings of the study is that vitamin D deficiency increases the risk of death from any cause. Another important finding of the study is that it was the levels of 25-OH-D (calcifediol, a biomarker of of cholcalciferol (vit. D3) supplementation) and not 1,25-OH-D...- haidut
